  1. finally.. if they had that customisable power / ride feature already I would have been way more likely to go with a bosch motor’d bike
  2. I’d agree except Bosch don’t sell bikes. They have frozen out a massive revenue stream of people with nearly new bikes who aren’t ready, can’t justify or can’t afford a new bike bike but could be tempted to upgrade to get better connectivity or adjustability on their current bike.

    True. I’m sure they could have designed backwards compatibility though and made the decision not to

    Thinking about it, if current Bosch motors were capable of customising the power modes, all I’d do is increase the power on all modes and as result decrease overall range, so sometimes less is more!

  3. Is new CX motor and 750Wh battery still 36Volts?
    If it is 48V, thats the answer why is not backwards compatible.
  4. It is an easy question whether or not there is a new engine because it is not clear to me

    Will there be a new Drive Unit?
    Answer: Yes, it will be a new one
    Performance Line CX. This Drive Unit
    will be the first engine of the system
    intelligent.
    How is Performance different
    Line CX AM22 of the current model?
    Answer: Performance wise, the
    Performance Line CX for the system
    smart is identical to the models
    current, but has other takes for the
    connecting the cables and connectors
    New development. The current model is
    will remain unchanged.

    Drive unit has identical performance, gearing and all drive / performance hardware the same, but, new electrical connectors so it fits with the new controller / Kiox / battery etc.

    So yes technically it is new, but only so it works with the new peripherals. There are no performance changes or improvements.

  6. Blimey, so bikes fitted with the new 750Wh battery could be nudging 26kg…

    Maybe I’m in a minority but I prefer the smaller battery and range extender route.

    • The new Flow App allows for unparalleled customisation of the riding experience and game-changing over-the-air updates.

    The most important feature may perhaps be OTA updates. That was a huge fail on Bosch’s part to require dealer visits (and fees) for firmware and software updates.

  8. Blimey, so bikes fitted with the new 750Wh battery could be nudging 26kg…

    Maybe I’m in a minority but I prefer the smaller battery and range extender route.

    As seems to be the fashion – they keep using heavier cells each time a company makes a larger battery .. :p :unsure: :ROFLMAO:

    500wh Battery : 349mm – 2.9 kg
    625wh Battery : + 125wh + 67 mm + 600g
    750wh Battery : + 125wh + 68 mm + 900g !

  9. What would be the benefit if the battery is 48V?

    There where rumors that bosch will go 48V.
    Anyway no problems with 36V Bosch has an effektive system.
    Think the motor will be quite similar, dont really understand why they made a different
    charging interface and say this system will not be able to use dual battery.
    Would make much more sense to me if you could use 500/625 powertubes with adapters in
    the 750 tube.

  10. Is new CX motor and 750Wh battery still 36Volts?
    If it is 48V, thats the answer why is not backwards compatible.

    We asked whether it was 36V or 48V, unfortunately they didn’t answer.

    But they did answer our question about changes, that has been published previously in this thread. There are no changes to the motor hardware. I’m guessing that means it’s still 36V. A 48V motor would require different gearing I assume. Motor rotation speed increases with Voltage.

    Also, using the most energy dense cells of today, the only way to get 750 Wh is to go 36V: 60 cells * 3,6V * 3,5Ah = 756Wh

  11. So… if you can buy good old Bosch 2021 system in good price, go for it! Isn’t worth to wait to get this poor purion 😉 Especially the new bikes will be a 20% up priced…
  12. Pity the 625wh battery can’t still be used, I’ve a spare that’s handy for bike park days 😢 otherwise it all looks great imo 👍
  13. Am I the only one preferring the old Purion over the new controller? The Purion still seems to be easier to use and then it has the speedometer too without the need for an extra display. The new controller isn’t exactly minimalistic.
  14. Exciting to see things keep developing. I must say I’ve been disappointed with the EP8 range after I switched to a new bike a few months ago and miss the 700w from my Levo.

    I can’t wait to see what hits next year with this 750w system, the Bosch is a great motor.

    As for the pace at which developments create obsolescence I think that’s part of the territory with new technology, we all want the next best thing and thats what the market constantly try’s to deliver.

    we have to chose if it’s enough each time to buy in to the next best thing.

  15. The battery is the same than the actual 625Wh, just more cells (of the same type).
    So more lenght (will not fit in my backpack like my spare 625), and much more weight.
    The only thing interesting in this new system is the modes customisation.
  16. We asked whether it was 36V or 48V, unfortunately they didn’t answer.

    But they did answer our question about changes, that has been published previously in this thread. There are no changes to the motor hardware. I’m guessing that means it’s still 36V. A 48V motor would require different gearing I assume. Motor rotation speed increases with Voltage.

    Also, using the most energy dense cells of today, the only way to get 750 Wh is to go 36V: 60 cells * 3,6V * 3,5Ah = 756Wh

    It still is 36V.

  17. To make the motor that isn’t even 2 years old effectively obsolete is quite an achievement.

    Considering the motor is the same hardware, i don’t think this is the case. You just need to take it to shop for motor firmware update. Not that big a deal. I can’t see any reason why this motor wont get any future performance updates as the new model, considering they are identical drive wise.

  18. You would get the same output wattage at lower current. Most likely less losses transferring current.

    Less heat loss due to the lower amps used, higher cadence levels without having to resort to computer optimisation ( meaning better range ) and a few other incrementals such as better use of the new higher density 21700 cells now available ( 39 cells v 60 18650 cells )

    Bafang now seem to be pushing the 48 volt route, Mahle is already 48 volts, will 2 years time be the big shift to a Bosch 48 volt motor ?

  19. I don’t fully understand. First you ask for custom modes, nicer displays and controller. When they make it by changing the drive unit electronics you cry like a baby for backward compatibility. Has there been some promises for this?

    Luckily there’s a lot of old bikes with current setup and the rest can buy the both generations to really enjoy Bosch products.

    Range extenders are marginal business.

    I think this was good step straight to year 2021. I have old GEN4 and don’t feel bad for it.

  20. How does the Bosch compare to the Brose system for pedalling resistance once your over the speed limit – I ride with friends who have Cube Stereo & Spec Levo’s – the Cube gets dropped big time once over the 15mph limit? Looks like the mechanics are the same for this Bosch upgrade?
  21. The new controller isn’t exactly minimalistic.

    It needs to be large to hold the new 750wh battery :) It just needs a few more buttons on it or maybe a full size keyboard ?

    Lets make it larger than most displays – but not have a display … 🤯

    All the Purion needs is battery percentage rather than bars and it would be perfect,

    And tactile/haptic buttons so you can feel if you’ve actually pressed them or not.

    And a shape which enables you to mount it at the angle you desire in the position you desire.

    And a smaller screen – or little raised rubber bumper bars if it has to bet that large.

    And a slide out Specialized swat took kit as it’s large enough to accommodate it.

  22. It is an easy question whether or not there is a new engine because it is not clear to me

    Will there be a new Drive Unit?
    Answer: Yes, it will be a new one
    Performance Line CX. This Drive Unit
    will be the first engine of the system
    intelligent.
    How is Performance different

    smart is identical to the models
    current, but has other takes for the

    any new materials being used?.. no
    any efficiency gains?.. no
    any peak power improvement?.. no
    any harder wearing inner parts?..no
    any weight savings?.. no
    any sound differences?.. no
    any cadence differences?.. no

    So want changes/enhancements has the "motor system" been given? Am I right or wrong?

    sorry, Im feeling pessimistic.

    New screen, more cells, different software? Yes??? What about the motor?

  23. How does the Bosch compare to the Brose system for pedalling resistance once your over the speed limit – I ride with friends who have Cube Stereo & Spec Levo’s – the Cube gets dropped big time once over the 15mph limit? Looks like the mechanics are the same for this Bosch upgrade?

    Your mate with the cube is in the wrong gear/unfit compared to the others. There is no drag from the motor on the bosch when over the motor cutout speed.

  24. To make the motor that isn’t even 2 years old effectively obsolete is quite an achievement.

    How is the old motor and system effectively obsolete?

    Just because it is not the latest model, and not upgradable to the latest model, that does not render it obsolete.
    My 2020 Gen4 will continue to work just the same as when I bought it, despite there being a newer model.
    Just the same as my Lyrik continues to function despite the introduction of a Zeb, and my 2020 Whyte works just the same despite the introduction of 2021 and 2022 models.

    Hey, If Spesh can say a motor is new and call it a 2.2 when it’s exactly the same as the 2.1 has been for the previous 6 months, then Bosch can say exactly the same motor is new too.. Though it does sound like maybe they’ve added/enabled bluetooth in the motor and possibly changed firmware only settings to now be software configurable settings. So, some new boards, but not mechanical changes.

  26. No, you’re not. All the Purion needs is battery percentage rather than bars and it would be perfect,

    I agree, all I would like is a percentage display instead of bars.

    I’ve got no interest in phaffing about tweaking settings with an app, and while more range is appealing I think 625wh is a good balance of range/weight ratio. If I wanted the odd epic day out then I’d go the whole hog and buy a spare battery instead of carrying extra weight around all the time.

    I’m more than happy with the bike I bought a month ago and no doubt this new package will stick another 10% on the price of the already overpriced bikes fitted with it.

  27. Your mate with the cube is in the wrong gear/unfit compared to the others. There is no drag from the motor on the bosch when over the motor cutout speed.

    Totally. The Gen4 is zero draggy (Still a pig with 25kg’s of bike and tractor tyres, but you can still really push on if you accelerate past the limit, it drops off smoothly and kind of pushes you over it). But then the Brose is pretty much Zero draggy (but has a much harsher cut off). Maybe he has draggier tyres, draggy brakes or all the Brose’s are de-restricted ?

  28. Hold up, I’m confused!!

    This new system allows the firmware to be updated over the air and the wiring has been reworked. Plus the release of a 750wh battery and the scope to allow the motor perameters to be adjusted via the app.

    Doesn’t it stand to reason that Bosch will eventually release a firmware update to increase the maximum current flow from the battery, thereby increasing the newton meters of torque?

    I think it’s more likely that as they’ve changed the boards in the motor, they’ve made other changes at the same time on how things communicate and work together – possibly improving efficiency and communication protocols between battery management systems and the motor . So, they’ve changed the connectors so that only "compatible" items can be used with the "bes3" ? configuration. Presumably they looked at making things backwards compatible, but made the decision that it wouldn’t work, therefore, use different connections to avoid issues down the line. They might also be improved connections which are more weatherproof for instance.

    We’re still very much in a growing phase, you can’t keep making things backwards compatible because the technological changes don’t allow mowing forwards and legacy compatibility. Plus, the new controller obviously has star link satellite built into it ..

    Completely agree…..if I need more range I’d plumb for a spare battery
    rather than a new model. I bought the bike because it’s mechanically relatively simple to service and hopefully when or if I require attention to the motor after the warranty period has expired there will be independent establishments to carry out the work.

    More current …. more watts… more strain on motor parts. I cannot see manufacturers pushing the boundaries of motor performance by allowing updates on how many amps the Motor can and will draw.

    You never know apac.

    If the EWS-E taught us one thing, it was that Bosch system seemed to have the advantage on the Power Stage.

  33. Interestingly enough, I’ve just heard that this new system will allow you to run either Shimano DI2 or Sram AXS.

    Are they suggesting that you can run either system without the batteries or will it just connect via ANT+?

  34. Interesting, but gone the opposite way I wanted really. I’m happy using Garmin stuff for ‘smarts’ and just want a minimalist controller like an EP8.
  35. Have to say very disappointed with the updates – yes the new systemis an improvement, but it’s like they totally ignore feedback from existing customers/reviews about giving an option for a minimalist controller.

    I really like the Bosch motor, and it’s EMTB mode is the best off the shelf software setting of any motor system IMO, but the user interface is so poor.
    How difficult can it be to just make a simple controller that isn’t a wart on the handle bars – the old remote was from the 80’s, the new one has bought it into the 90’s.

    I also think they have missed a massive trick by not making a version of the remote available that is retro compatible.

  36. Interestingly enough, I’ve just heard that this new system will allow you to run either Shimano DI2 or Sram AXS.

    You could run DI2 with the older Bosch systems, including GEN 3 and it would show the info on the display etc

  37. What the f*** is that ? 😆 Reminds me of a sound box I had on my bike as a child. I had police sirens, machine gun noises and motorbike engine sounds 🤙🏼

    A Raleigh Vektar! One of my mates had one, and everyone was well jealous. It eventually got nicked from outside Asda along with my Raleigh Mag Styler!

    The Vektar was essentially a Raleigh Burner, with a motocross looking body kit – which housed some really cool (super shit nowadays) electronics. It’d play some weird noises, display your speed, and had a radio built in. If I remember right, it had a Grifter style hub gearbox too.

    Grifter gears… Blue, yellow, red…. usually stuck in red👍

  39. Some of the features would be nice to have, namely finally being able to tailor the power modes, but the battery just being longer means bringing the centre of gravity further up along with adding extra weight. As it stands the 625 is fine for all my rides to date. I guess we’ll see how this develops and the equivalent to the orbea rise would be the logical replacement for me in the future. Not really too bothered about anything new as the bike does everything i want to date.

    Has anyone noticed how much of a £ premium the update is costing?

  40. It does nothing to excite me ..I might have got a little bit enthused had it been backward compatible but as it isnt ..couldnt really give a toss..
    I will read the blurb in a ( good) few years time if & when I’m ready for a new bike ..
  41. I’d be lying if I said a bigger battery, new display wouldn’t be welcome, but I bought fully aware of the forthcoming upgrade and decided to buy anyway.

    These bikes will take a while to hit the shops and supply will still be an issue.

    If you wait for the upgrade on anything, you lose decent riding time in my opinion.

  42. i think it quite telling the difference between a sytem designed by an electronics/engineering company and by a dedicated bicycle components company.

    With Bosch it seems very much the design is based off “it’s a bicycle, has a handlebar so we just need to attach whatever we need to it” without considering how most riders set their controls up or how their control will play nicely with other components.

    With Shimano and Specilized they have really thought about how the controls would integrate with other components that mount to the bars, how the cabling would play nicely etc.

    for me this is exemplified by how the cable comes out of the new controller – pretty much every other brands control has the cable coming out on the underside of the bars, so it can be routed neatly with other cables etc and out the way.

    Bosch still have it coming out the end meaning it’s impossible to make it look tidy or route nicely.

  43. What about that new anti-theft feature? That could actually be useful. Is there any detailed information out about that?

    I’m guessing this controller is more aimed at commuter and cargo bikes. There’s too many buttons. Five in total. EMTB’s only need two, plus & minus to change through the modes. I cant figure out what the left & right buttons would be for or the little one in the middle

  45. What about that new anti-theft feature? That could actually be useful. Is there any detailed information out about that?

    Bosch is creating the ConnectModule. It’s not ready yet, but they encourage the bike manufacturers to make room for it when they design their bikes. This unit enables you to trace the bike without a bluetooth connection for reporting position

  46. Bosch was focusing a lot on the future of mobility when they presented the Bosch Smart System. So it’s not primarily an emtb system. They talked about future possibilities, like exchanging data with driverless cars and such.

    If I had a -20/21 Bosch motor and wanted some kind of app support, Id check out the latest Nyon display. It seems much smaller than the old. I’m sure it’s expensive, but if the Smart System was backwards compatible, upgrading would probably cost quite a bit too.

  47. Less heat loss due to the lower amps used, higher cadence levels without having to resort to computer optimisation ( meaning better range ) and a few other incrementals such as better use of the new higher density 21700 cells now available ( 39 cells v 60 18650 cells )

    from where you get that?

    Left & right buttons could be for indicator lights maybe (on commuter & cargo bikes)

    Don’t disagree with most of this but it occurs Bosch are designing for use across different manufacturers & consequently there’s a one size fits all ethos. No idea if it’s the case but wouldn’t surprise me if the same company making one of the best drive units has enough about them to have thought about next gen AND ended up with this because reasons.

  50. We have a Bergamont E-Ville city bike in the family, which is an amazing ebike, definitely has the best integration and seamless performance of any ebike I have ridden, has DI2 Alfine gears fully integrated into the Bosch system, and you use every button on the controllers , and it all makes a lot more sense than how they work on an EMTB. I just think that it’s a real shame that they haven’t (as yet) produced something that is really sorted fro off road use.

    Shimano make multiple switch units all cross compatible across their systems, i just don’t get why Bosh can’t do the same.

  51. Just canceled my long awaited Orbea Wild FS order and have my name down for the 2022 Cube 140 HPC TM 750 29 due late October. Glad that my Wild didn’t come in as forecasted, the updated Bosch system is worth the added wait and cost.
  52. new higher density 21700 cells now available ( 39 cells v 60 18650 cells )?
    from where you get that?

    Look up Samsung 21700 50E and Samsung 18650 35E specs , 2 of probably the best batteries out there and then you maybe can work it out. Report back with your findings 😎

  53. This is aimed at new emtb riders/ buyers. It is not worth upgrading from my 2020 gen 4 to this model with same power output.
  54. So a "TCU" without lights …

    Yet …. it gives to possibility that it will/could have mode/power lights – like a Spesh TCU – which means there might be a handlebar controller due down the line without the unnecessary items like bow thruster control and quick dial.

    It seems as if the "+"-button doubles as light switch (image below).

    The left/right arrows are for swiping left or right on Tinder.

  55. This is aimed at new emtb riders/ buyers. It is not worth upgrading from my 2020 gen 4 to this model with same power output.

    I agree that the fact the motor is essentially unchanged makes upgrading less attractive to existing gen 4 owners. I’m not sure if I would bother with customizing the modes either, for myself I find EMTB perfect right out of the box. I would however love to be able to update the firmware myself, and I think this is something Bosch could have made available for the existing Kiox with a simple software update.

    What if it was mandatory to change all electronics in the drive unit to make the over-the-air updating possible?

    I don’t know what problems I would currently solve on my Bosch CX 4 by updating the firmware. There has been no real changes in the last two-three updates.

  57. As I’ve just bought a new Trek Rail my first reaction when Rob posted this up was ‘bloody hell’. Now having thought it through and seen what it all means and what the reaction has been I’m not at all bothered.

    Bigger battery is too heavy – I’m happy with 625, esp compared to the 378 I had on my old Focus Jam2. If I get a new bike in the future I want it to be lighter not heavier.

    Controller – looks like something out of Star Trek. No thanks.

    Kiox display – looks like the old one. I quite like the Kiox on my Rail as I like having all the info tho I appreciate not for everyone.

    App – this is useful for tweaking, but tbo I’m quite happy with emtb mode and I don’t feel a desperate need to change anything.

  58. It’s difficult to say how much heavier the 750Wh battery really is. Unless I’m mistaken, the frame lock mechanism is integrated in the battery. Or possibly just parts of the mechanism. That means fewer parts in the frame and reduced weight. But the Powertube 750 will of course be at least 500 grams heavier due to more cells.
  59. The 750 is 900g more than the 625. The 625 is 3.3kg, so the 750 comes in about 4.2kg give or take.

    Same as Bbear. While the Purion is a wart. Otoh when I ride, I’m focused on where I’m going, what the bike is doing beneath me & all the rest of it. Also never felt the need to customise the modes, EMTB is decent off the shelf & mixing tour & EMTB, my 25kg push iron with a 625 is good for 50 miles, more than enough for a big day out. Nice things are nice to have but for me this solves a problem I don’t really have.

  60. I’ve never been bothered by the purion display tbh but I wouldve loved the ability to customise the power modes. Seems theres a few things that can be tampered with and not just how much power each mode has.
  61. From post #37 again :

    500wh Battery : 349mm – 2.9 kg
    625wh Battery : + 125wh + 67 mm + 600g
    750wh Battery : + 125wh + 68 mm + 900g !

  62. The 750 battery is 4.4KG

    View attachment 70364

    That’s some weight gain on the battery. Although looking online ‘claimed weight’ for the 2021 Cube 160 HPC Action Team Spec bike

    625wh – 24.1kg
    750wh – 24.3kg

    So that gain has been offset a fair bit. Mainly down to the fixed battery but guessing elsewhere too.

    How that weight is placed and handles time will tell, but that extra battery and 200g of weight will surely see a range improvement on what is already a very efficient system from what i’ve seen.

  63. And for reference, the Spesh 500wh weighs 3135g.

    So in terms of comparison :

    Bosch 500wh – 2.9kg’s , Spesh 500wh 3.135kg’s

    Spesh 700wh : 3.840kg.

    Bosch 625wh : 3.5kg’s
    Bosch 750wh : 4.4 kg’s.

    The Spesh 500wh uses 18650 cells. The 700wh uses 21700 cells. If the 700wh used the same cells as the 500wh then proportionally, it would be about 4.4kg’s. Likewise, if Spesh made a 21700 cell 500wh battery, it should be about 2.75kg’s instead of the 18650’s 3135g – but they don’t.

  64. What if it was mandatory to change all electronics in the drive unit to make the over-the-air updating possible?

    I don’t know what problems I would currently solve on my Bosch CX 4 by updating the firmware. There has been no real changes in the last two-three updates.

    I was meaning version updates, and the new modes like Emtb Lite, Tour+…it would be great to be able to experiment with these without having to take the bike into the shop, as well as being able to change wheel size, crank length etc yourself

  65. Yeah, I didn’t intend to ask about the weight of the 750 :) The point was the weight isn’t comparable. To my understanding, components for the lock mechanism has been moved from the frame to the battery. This makes the frame lighter and the battery heavier. So the net weight increase should be way less than 900g.

  67. Sounds a good move does this. Yamaha dont appear to be sitting still atm.

    It’d be great if Kawasaki, Honda & Suzuki started making e-motors too and the Japanese manufacturers made some emtb’s. Partnered with Shimano components. Maybe in 5-10 years they will, time will tell

    I suppose if motorbikes are going to be all electrified up at somepoint then possibly Honda, Kawasaki et al might reach a little further into emtbs as theyd already have a similar(ish) tech on their mainstream bikes right!?

  69. It could be be possible that by fully redesigning the whole system it’s now possible to introduce new controllers in the future.

    No idea, I just thought a Kawasaki Ninja ZX-EMTB would be cool as f*** 😀

  71. One look at that controller and I already know that I will not have a Bosch powered bike for my next one.

    View attachment 70376

    That is the crappy controller on the G4 KIOX and it is forking less than useless when compared to other current offerings.
    Don’t mind the KIOX display too much, but that controller is SHITE.

    You don’t like it then ??

    Lets be glad Who ever does "Controls" at Bosch Bikes, doesn’t make gear systems. Imagine the Bosch 12 Speed – you’d just have 12 levers hanging off the bars to select the gear you want. Except they wouldn’t move very nicely and they’d all have a flush smooth finish so you’d have no idea which lever you had your finger on. They might combine it with an enormous Gear Display screen, which just shows a horizontal bar rather than the gear number.

  73. We’re getting a bit off topic at the moment ???

    We are, but it’s kind of related. It’s all about brand association and the expertise and experience of those brands.

    When I think about Bosch, I think of washing machines, drills & lawnmowers, not EMTB’s

    Yamaha however have a long history of designing engines, frames & suspension systems so they are the only motor manufacture (perhaps Shimano too) that I immediately associate the brand with bikes. Makes sense for the other Japanese manufactures to jump on the emtb bandwagon. The Japanese brands are highly competitive with each other and therefore always pushing for innovation, have strict quality control, can mass manufacture to bring prices down, and could easily dominate the e-bike market if they decide to dip their toes into the market

  74. When I think about Bosch, I think of washing machines, drills & lawnmowers, not EMTB’s

    I guess that’s all just based on consumer perspective though. Where as Bosch are a huge automotive supplier (60%) and many other things. Obviously best known globally for making the most horrible switches and displays for ebikes.

    Kawasaki are Kawasaki heavy industries who make massive ships, planes, defense equipment and dabble in engines and motorcycles.

    Honda were primarily motorcycle, then car and now do robots and jets – Honda would be the interesting one if they did make an EMTB from the ground up especially after they stunning DH bike.

    Like many of these things they get convoluted. Yamaha motorcycles is a separate company from Yamaha. Not sure which part makes their bike motors and bikes though. They’re the worlds largest producer of Pianos. But make all sorts of music equipment, jet ski’s, golf buggies, skow mobiles, out board motors, robotics and so on.

  75. From post #37 again :

    500wh Battery : 349mm – 2.9 kg
    625wh Battery : + 125wh + 67 mm + 600g
    750wh Battery : + 125wh + 68 mm + 900g !

    so it’s 49cm, at least 13cm less longer that 700WH specy one. maybe if you are fit you can carry one on your backpack:)

  76. I would like to see a lighter system and bike with a kind off 500wh battery. Domage Bosch only went for upgrading with heavier battery.
  77. 200g looking at the Cube as an example 👆

    I think the weight of the Cube is pretty interesting, as its a good KG lighter than the other bikes we have seen released with the 750, and doesn’t exactly have light components on it, and historically Cubes have been pretty heavy despite the carbon main frame, often as heavy as alloy alternatives.

    As you probably already know, marketing material and real world numbers often differ. Maybe this is the case here?

  79. As you probably already know, marketing material and real world numbers often differ. Maybe this is the case here?

    Cube said in their press live video they were able to shave off the equivalent weight in the 2022 frames so the 2022 total bike weight was near identical.

  80. Looks like Haibike are now 150KG system weight, so no doubt chunkier frame and components but heavier bike weights.
  81. I guess that’s all just based on consumer perspective though. Where as Bosch are a huge automotive supplier (60%) and many other things. Obviously best known globally for making the most horrible switches and displays for ebikes.

    Starter motors, alternators etc are a big market for them. They need to have a bike manufacturer take ownership and do software and astetics development – like Spesh with Brose.

    Kawasaki are Kawasaki heavy industries who make massive ships, planes, defense equipment and dabble in engines and motorcycles.

    Ddidn’t I see a move about them? Planes, Trains & Automobiles ;)

    Honda were primarily motorcycle, then car and now do robots and jets – Honda would be the interesting one if they did make an EMTB from the ground up especially after they stunning DH bike.

    Oh hell – YES PLEASE. Got to freewheel Gregs RN-01 down a gentle hill when he was over here for the WC. Honda would do a brilliant job I expect.

    The Yamaha YDX Moro was done by Yamaha Motor Corporation USA as an inhouse project.
    I don’t like the split frame design but I guess someoene will come up with a frame cover.

  82. Left & right buttons could be for indicator lights maybe (on commuter & cargo bikes)

    The Kiox needs at least five assuming they’re keeping the general UI design (cardinal directions plus a confirmation button). I’m sure that’s driving the controller design.

    So for folks who run without the Kiox I suspect it will be a bit like so:

    View attachment 70447

  83. I wonder if they will use the same architecture on commuter side like replacing the 3rd generation CX and other. I guess it would be a bit surprising if the 4th generation CX would be the only one model.

    One thing that’s interesting that if you can connect a HRM-belt then there could be theoretically a technical option to connect the drive unit through ANT+ or Bluetooth to a bike computer?

    I guess it depends a little on the fact that if Bosch wants to keep it’s ecosystem closed or not. Specialized is up to something as they redesigned/defined the interface how external apps connect (like blevo)

    It would make sense to be able to use same Garmin/Wahoo/younameit computer on different bikes.

  84. It is possible to upgrade old CX gen4 motor to the new one? Will be all mount points the same?
    I know, the battery size is different. It’s bad question.
  85. Bosch eBike Systems unveils new smart system and vision for e-mobility

    Headlines:

    • New 750Wh battery
    • New Kiox 300 Display
    • New Handle Remote Controller
    • New App to allow custom modes based on rider requirements
    • None of this is backwards compatible, its an all new system with new connectors

    • The new smart system combines digital developments and significant hardware upgrades to further enhance the eBike riding experience.
    • Bosch introduces a new large capacity battery, LED control unit and streamlined Kiox display.
    • The new Flow App allows for unparalleled customisation of the riding experience and game-changing over-the-air updates.

    Is it going to be integrated to Trek W-bikes?

  86. True. I’m sure they could have designed backwards compatibility though and made the decision not to

    Thinking about it, if current Bosch motors were capable of customising the power modes, all I’d do is increase the power on all modes and as result decrease overall range, so sometimes less is more!

    Bosch motors have always had customisable power levels, right back to the Gen 2 but they never shouted about it so not many realised it was possible! You did need the Nyon controller to do this and the customisable power levels only worked to 15mph so no good if you were running a dongle.

  87. Just put down an order for my first eMTB, the Cube Stereo Hybrid 140 HPC Actionteam 750 29", with the new Bosch system. Expecting it to arrive 03/22. Did a lot of research before I put down the payment at my LBS, coming from a Yeti SB130 it was a bit difficult not to wait on their release, but with rumors of €10-12k+ I thought is was a nobrainer to go with the Cube and all that high end spec. and the redesigned frame that looks tits ! (€6700 where I live w/15% pre-order discount)

  88. Faster charging. Charging rate is limited by current. By going higher Voltage you can pump in more energy per minute at same current.

    Charge current is limited by the cells themselves and/or BMS/charging system. It’s irrelevant how many cells are connected in series (voltage).

    EG a cell rated at a max charge rate of 5A can’t take more just because it’s connected in series with others to create more volts. The current would still have to remain at 5A, although the charger would simply do it at a higher voltage.

  89. How can they get the controller so wrong!?

    I think theyve got the motor and batteries bang on right, and overall are probably the best motor/battery combination, but the controller/displays just ruin it. MtBers buy the system despite the controller/displays.

    All they need to do is look at what other manufacturers are doing…….

  90. How can they get the controller so wrong!?

    Agreed, I prefer my ‘archaic’ Purion which has speed, distance, battery level, buttons etc all on one small screen. The only thing of any worth to me on the new system is the handy extra 125Wh but even then at a nearly 1kg consequence it’s a debatable point given the weight of the bike as it is!

  91. IMHO, the idea of the switchgear is good, but the design looks quite awful. I like the idea of being able to use it without the display unit, and the fact that it gives more information than say the little Shimano unit. I wish it was smaller.
  92. What should have to be changed on kiox/nyon21 to allow updating the motor unit firmware?
    And what should have to be changed on kiox to allow user settings the power curves or at least some kind of a constant for multiplying the total motor support? (That allows a finer power reduction by user for longer battery life)
  93. Charge current is limited by the cells themselves and/or BMS/charging system. It’s irrelevant how many cells are connected in series (voltage).

    EG a cell rated at a max charge rate of 5A can’t take more just because it’s connected in series with others to create more volts. The current would still have to remain at 5A, although the charger would simply do it at a higher voltage.

    Correct but if you have 13 cells in series all charging at x number of Watts, then it’s only reasonable to assume 10 cells at X Watts is going to take longer to charge a pack to 720 Wh’s than the 13 cells.

  94. Correct but if you have 13 cells in series all charging at x number of Watts, then it’s only reasonable to assume 10 cells at X Watts is going to take longer to charge a pack to 720 Wh’s than the 13 cells.

    Totally lost me there.

    The only way you can charge faster is to use more current. The original post suggested that a higher voltage battery can be charged faster.

    The current limit is based on what the cells themselves can take. How many cells you have in series (the voltage) is irrelevant in terms of the max current you are able to use.

    You can’t charge a higher voltage pack faster unless A: the cells are rated to take a higher charge current than the previous cells used or B: the charger manufacturer chooses to push the current output closer to the max cell rating (which many chargers don’t). Either way, it’s nothing to do with voltage.

  95. Randomly I bumped into a test team from another manufacturer whilst out in the Surrey Alps this morning.

    They where of the opinion that the updated Bosch ecosystem is very much geared towards the commuter/cargo bike market and was designed with that in mind first and foremost, but that since the brands that use the Bosch system are desperate for bigger batteries (in their opinion the battery capacity arms race is far more important to generating sales than lighter more minimal systems) they dont have much option but to sling it in the bikes.

    They couldn’t believe that Bosch wasn’t working on something more minimalist in terms of controls though, as their market feedback is that the two most requested things are bigger batteries, and for EMTB’s to look as much like a normal bike as possible, with minimal clutter.

    Having said that we did have a bit of a laugh, as its really only a small percentage of geeks like us on Forums who get wound up about these things, and most people buying ebikes couldn’t give a sh!t :cool: and Bosch probably realise this. They also agreed that the bikes ride much better with smaller batteries, but that the market wants as big as possible.

    what were they testing ????????

  97. 4A on 36V is not 4A on 48V. The 4A charger for 48V needs more power and can produce more heat with equal effectivity as the 36V charger. But its not mind.

    It’s all a bit academic chaps, we all plug our bikes in and when the green light comes on, we ride. Whether it takes 3 hours or 4 is almost never a problem.

    It’s not unlike ‘performance’ cars; everybody admits to enjoying a lighter car more, but then they go and buy some bloated, numb, ill-handling dogpile because it has a bigger number in the ‘power output’ box.

    Audi RS# are prime examples.

  100. I think its horse for courses – to follow your analogy, I once had an RS4, about 15 years ago, and the reason I got it was I wanted a fast car, but also wanted to be able to nail it down to the alps with a full load of bikes/snowboards etc, and it was the best option at the time.

    In an ideal world you would have a little ripper of a bike, and something for longer trips, but at current prices the luxury of owning 2 EMTB’s isn’t viable for most people.

  101. Does anybody know if production of the current spec stuff is going to end with this update?

    So will any bike company selling Bosch powered bikes either have to stop production or change their bikes to suit the new battery dimensions if the current product is ending?

  102. Sorry, but no one feels the need to have a smaller handlebar control? The new KIOX is hugly, bulky and redundant in features. A huge disappointment for someone like me who loves a minimalist setup and little exposed to breakage in the event of a fall.
  103. Sorry, but no one feels the need to have a smaller handlebar control?

    Agree, people complained about the Purion, which I don’t mind that much, but with this latest system Bosch have gone backwards rather than forwards, the new controls are even worse

  104. I still don’t understand why one of the big players hasn’t made a wireless controller yet. Sram do it with AXS and it’s super reliable and lasts two years. I’d love to get rid of that cable.

    No Shimano rubber bands required….

    I agree. How are you expected to hit the buttons you want on rough terrain or with gloves on? Be like trying to use a Casio calculator watch. 🤔

  106. Bosch mention that the 2022 CX is a new drive unit but with identical performance.

    Interested to test and see if there’s less internal motor rattle. It’s noticeable going to the silent Levo to the current Rail with the Bosch motor rattling on chunky stuff.
