I have 2.6 front and 2.4 rear. 2.4 rear is about the max I would go for muddy ridesHas anyone put a 2.6 tyre on the front and back yet ?
Seems very tight and concerned when it gets muddy in the uk. Had a intense tracer 275 and it was like this and got ruined

there is a miles/time to empty screenDoes anyone know how to make the battery % in the display bigger?
It is tiny and is the only number I need.
It’s not an option in the app.
there is a reason the WC downhillers like Loic bruni use 2.3/2.4 only. traction in corners,I have 2.6 front and 2.4 rear. 2.4 rear is about the max I would go for muddy rides

Between 30/30 and 60/60. I thought Auto- would be the most conservative but dynamic micro tune is way better. If you have a screen with your power output, bike power output, and support/power, you can really dial in the micro tune to preserve. Just know what you can put down for watts for the given ride length and adjust the micro tune to the given the steepness.
@Monstermax4 nice stats what was your dynamic tune setting most of the ride? With 165lb you are aweight, easy on the motor.
My sworks came with 2.3 Specialized. One ride and I replaced them with Maxxis 2.5 front and rear, much better size for the bike.I have 2.6 front and 2.4 rear. 2.4 rear is about the max I would go for muddy rides
Hey @emtbeastThanksI have been following the thread and yes most reported Auto is a battery eater, pretty much the same on all systems as it's automatically adapts the motor output to keep you at your current speed, in uphill trail conditions that's not really ideal for range. I agree the Dynamic micro tune is most probably the best way if you want most range.
If someone is interested some info I got...
I did an 1h test ride with an S-Works recently in Riva, got a bit higher consumption than you, although I didn't baby it, pushing hard in a mix of all possible modes and I weigh 200lb+.
The motor settings were all on default.
This is what comes to my mind, the motor works seamless, it's there, it's doing it's job, not bothered by what you do on the pedals. It doesn't feel like a race motor it's also not like a diesel like feeling, it's something in between, like a jack of all trades...just moving along with you. I didn't have time to play with the settings, so maybe it can be tuned to a more aggressive character, maybe someone can tell more.
Also my friend and I did a follow up test with the new Bosch with the 100Nm update and by it's side the new Bosch without the update. These two side by side are night and day.
The character of the updated motor in Emtb+ and Turbo is something else, it borderlines on a race feel but in a controlled way, hard to describe. The motor if pushed fast from a slow roll makes a RC car really enjoyable electric spool up sound, it's pretty cool as you know it's doing it's thing, when riding along it's really really quiet.
Comparing the Spesh 3.1 and the updated Bosch I would say: noise levels pretty much the same really quiet when riding allong, maybe I would give a slight edge to the Bosch(but could be the frame), internal motor resistance feels better/easier on the Bosch, acceleration no real difference, no rattle from either.
On the test loop cca 1h 14km, 500m altitude, the consumption was cca 5% higer on the Bosch(which is to be expected due to higher peak power).
Hey, thanks for asking this is a really hard one, I would be doing injustice to either off them if I had to choose, both motors are really good, hard decision even for me with a back to back test behind me. Either one would probably satisfy anyone, either one has something going for it.Hey @emtbeast
Thanks for your report
Which motor is more power full for you ?
Is there a big difference you can feel between the Bosch 100nm and the 3.1 SW ?
Big thanks for the times taken to reply me.Hey, thanks for asking this is a really hard one, I would be doing injustice to either off them if I had to choose, both motors are really good, hard decision even for me with a back to back test behind me.

I tested the Spech first and the Bosch after.
My first feeling after both was that the Bosch felt more powerful, you could better feel the way it accelerated up to 25kph, it felt a bit aggressive, I really enjoyed the motor spool up sound, if it can be described like that.
The Spesh 3.1 was no slouch either, it picked up speed to 25kph really fast also but in a more gentleman like way, I couldn't feel any aggressive character, maybe that's why the Bosch also felt stronger.
Both motors held 25kph uphill really easy, the uphill grade there was cca 7%.
I also had the feeling the Spesh 3.1 didn't change the sound pitch alot or It did it less pronounced than Bosch, this could have also contributed to a less powerful feeling of the 3.1
Once working hard the Spesh motor has a more like a muted blender humming sound vs Bosch that has a more like an RC car sound. Neither of them felt intrusive.
One thing to note is that the Spesh 3.1 was on default settings.
I don't know on what settings exactly the Bosch was, I can assume it was default, but can't confirm as the bike Radon Deft didn't have the kiox 400c display yet and I couldn't check in the app. But looking at only a slightly higher battery consumption it was most likely in default settings.
If I had to choose from these two, I would go for the bike that suits my riding needs and trails I ride the most and would not think about the motor to much as both imo are Top notch.![]()
The way he cased every single jump leads me to believe the bike is very heavy and hard to get off the ground.
No one knows, except maybe a guy like FC, but either way, you end up with a tricked out G4 or a tricked out Amflow so it all works out in the end. (I bought G4 because of good LBS is a major major factor where I live)Does the gen4 bike improve success for these situations significantly enough to warrant the expense when you already have a tricked out 47 pound GEN3? Hoping that someone will undertake this comparison.
Precisely, that's why I have always ridden specialized. That may turn out to be why I keep the comp gen 4. The innovative Amflow will eventually be copied by the major bike manufacturers but it may take several years and also requires successful tarriff negotiations with China. All the cheaper model Amflow would need though would be a 170mm fork, better tires both of which I already have for backups, swap in the lightweight parts from my gen3 build, cost about $1000 less and a lighter bike. I only weigh 148 pounds dripping wet, ride tech trails no jumps, so don't need a coil shock/genie. Even the heavy weights doing videos haven't managed to break the Amflow. Just sayin.No one knows, except maybe a guy like FC, but either way, you end up with a tricked out G4 or a tricked out Amflow so it all works out in the end.

Skill issue, nothing to do with the bike.The way he cased every single jump leads me to believe the bike is very heavy and hard to get off the ground.
I have the gen3 and now 100miles on the gen4 and yes it is absolutely better in techical climbs and its the first real difference i noticed beside better handling in general. The motor has a much more natural and smooth power delivery and overun that helps you up without being noticible. my buddy who rides a gen3 noticed it imeadiately as well. The other big difference is downhill stability i found the gen4 is easier to control when it gets fast and rough so you are encouraged to ride harder. All of this translates to more fun. We are talking about subtlety, as my gen1 still feels great and is actually quieter than all of them.So I ordered a GEN4 Comp to avoid the May first 10% surcharge due to tariffs, but I can turn it down because the bike shop will easily be able to sell it. For me it is between that and an Amflow. Here's what I'm looking for and I have not seen yet. I need to see a comparison video of skilled riders in steep, technical climbs, where someone riding a GEN 3 stalls and fails to successfully make it without dabbing, but the gen4 rider can make it. I ride with a very aggressive group, some former pros, with good technical skills. But what happens is you get older and your heart rate max's out so you make mistakes and have to dab. With better bike or bike rider, they will not max out in these tough situations and will still be able make it without dabbing. Does the gen4 bike improve success for these situations significantly enough to warrant the expense when you already have a tricked out 47 pound GEN3? Hoping that someone will undertake this comparison.
Having full support for your ebike is very important. In my area its basically trek or spesh. I only have had two warranty claims in 9 years but quick access to spare parts is crucial if you ride every week. I already have a warranty claim on my gen4 taken care of and the part is in the mail acording to my LBS. the hotshoe cable was pinched between the motor and was working intermitantly. imagine trying to get two special cables from amflow in a week. bottom line is there are many reasons to support your LBS and the companies that have invested in your local and few reasons to take chances with china just to have more power and less weight, both arguably unnecessary.Precisely, that's why I have always ridden specialized.

Its a shame so many people hung up on weight. Spesh has balanced cost, weight, and durability while increasing performance. I'm here to say you only notice the weight when picking it up, not riding. My 120lb daughter on s4Yes it is
and it´s a shame!
I tend to agree on this perspective on the weight. Curious to know though: how much more complicated is to get and maintain a manual on the Gen 4 compared to Gen 3? Not that u manual all the time, but I think this would be a good “test” on the weight.Its a shame so many people hung up on weight.

was dropping me on my gen3. Had to tell her to slow down. Great moment actually as a Dad, but also showcased the bike capability. looked to me as the extra weight was helping her maintain traction and she was railing corners like never before. There is a reason why WC DH racers are adding weight to the BB of bikes. They like the feel of the ebikes they ride in training.
S4Nice build! is that and S3 frame size? What brakes are your running? Is that a Fox 38 fork?
