Strive:ON problems

The connector is bolted to the battery, or how is it secured?
It seems it has some kind of wook.


honestly to me it looks the same as the one shown in post n. 140
also because they are Bosch or compatible spare parts; and like the Canyon one it is screwed, moreover even the set of screws is a Bosch replacement (code EB1210001G)

It should be easy to check if the battery has any vertical movement once the clamp is closed on the latch. If there is no vertical movement the physical weight of the battery even including dynamic vertical forces when riding is ( in my opinion) unlikely to damage the latch. What will weaken the cam/lever action of the latch is any lateral movement of the battery. The zip tie hack, whilst not exactly elegant, is probably doing enough to prevent that lateral movement. I believe any permanent solution needs to focus on how the battery is held securely in the downtube rather than the latch......although it may also require a redesign of the ally plate used as the latch lever post. For me that should be steel and also have a much wider ( full width) fixing to the downtube, and that section of ( carbon) downtube should be reinforced to prevent flex.
 
Hi everyone, I think that the plastic skidplate is destined to last a short time, I hope that in the aftermarket, like Rockguardz, will soon make a more robust skidplate, in carbon or aluminium.

I wonder if you could put a bit of stiff foam between the battery and the inside of the downtube to stop it moving whilst waiting for the fix?

I suggested this a few weeks back within this thread and will be adding ‘Compriband’ seal to the length of the battery on all four ‘corners’ , but will initially wait for Canyon to send me the new designed replacement latch so I can then fit and forget.

Compriband is very thin (around 3mm) when first fitting, comes in a roll with self adhesive backing strip, but then expands over time (to around 15mm), which should create a nice firm fit within the downtube and eliminate any movement and rattle, especially on large hits or fast rocky terrain. Search for Tremco Compriband for further info. I’ll be fitting the TP651 variety.

That’s my unscientific and untested theory anyway!

Won't that make the battery non-removable though?

It’s a flexible polyurethane foam so the battery should be able to still be removed with a firm pull. It’s not a solid seal like expanding foam from a can.

My only concern would be the heat from the battery. The tape has a service temperature of -30 to +90 deg C. I’m not sure how much heat is omitted from the battery when in use

That was a concern I also had, and sealing either end will seal in any heat...
 
That solution also assumes any lateral movement is along the length of the downtube whereas the greatest flex could be the ally plate that the latch hooks into. It is not mounted across the full width of the downtube, is ally, and is mounted on the edge of a carbon tube. Any movement of the latch holder away from the cam operated latch lever would lead to the latch partially opening since it would allow the cam to move above the pivot point.

I’m sure @Zimmerframe has a thermal camera, maybe that could tell us how much heat a battery is omitting after a couple of hours of use

It gets less warm than you'd think.

I did mess around over a few days with a hub motored bike with an external battery (most things are exposed so you can monitor things more easily).

The warmer bits are the brake caliper and the actual cable going to the motor :

Different day : again, the power cable is the warm bit at the motor end :

1699952500513.png


Battery end : The cross is the bottom of the battery, where the cables and the battery control unit is. The warmer area under there is the frame which is acting as a heat sink. Interestingly (well, if you're sad :) ), you can see there's actually heat build up in the chain too.

I did recently test the battery temperature on the E-Mythique (Bafang M510). Test results over 7k, whilst trying to keep motor at max assistance (600+ Watts) - similar to my Gen4 in how it feels. 630wh battery. 5 Degree Celsius increase in battery temperature. Aluminium framed bike and underside of the battery is an exposed plastic case.

Unrelated, but interesting on the M510 you can monitor the torque sensor reading. 750 ish is no contact. The others are my foot resting on the pedal when taking screen captures - nice for testing if your Torque sensor is working properly.

Also totally unrelated, brake disks on different days after short runs.

Love these and the absolute geekiness to take the time to obtain the images. The heat in the chain is great 😎
 
The temperature on the bottom RH corner of the photos, i.e. -9.7 deg C on the last photo - is that the ambient air temperature ?
 
I managed to get out and test the latch fix kit from Tobias over on the EMTB Facebook page. Seems to have work and has held up after a couple of decent runs out (Rocky mountain terrain with lots of decent hits and a few modest jumps). No cut outs and the latch seems to be in one piece still. For such a small cost and a couple of minutes it seems like a great stop gap until Canyon and Bosch release the official remedy

Yes I fitted the Tobias latch too, all worked fine at the weekend but it was my first couple of rides on the new bike so early days yet
 
Does anyone have a link please? I've had a few looks and haven't found it yet.
 
An email reply from Canyon after enquiring about when the new latch will be made available:

“We are working with Bosch on a solution which is currently in the final testing phase. We cannot yet give a date for this, but as soon as it is available, you are welcome to request an optimised lock free of charge in the future in the event of a defective lock. We would expect Bosch or Canyon to release a statement at this point in time.

You will need to take your bike to your nearest Canyon Service Partner for this to be fitted and for the upper battery mount fitment to be checked at the same time.”

Good news, then we should send a Message to canyon or may be canyon will contact with all costumers?

I emailed and asked. Canyon’s reply was that the updated latch will be made available to purchase from their website ‘parts’ list for owners that don’t claim under warranty following a broken current latch. It won’t be made a recall so doubt they’ll contact all existing owners. Just keep on eye on here and the FB groups for updates as to when it is available.

What utter BS, expecting customers to purchase the fix for a known fault in their product! And forcing customers to go to a dealer to have it "installed".

They should be just posting them to all customers who request one, FOC.

I doubt it will be sold as an upgrade.

For the time being, and since there isn't an official statement or information from Canyon or Bosch, it's just wishful thinking and bs talking

Are you accusing me of spreading bs or Jake from Canyon Service Centre UK who I received the email from ?
 
Mario Antony said:
Do I ofend you? Why? This is a Canyon's and it's customer issue

No you did not offend me, your earlier shorter message wasn’t clear as to where you were directing the bs remark, but your more recent response has made that much clearer thanks.

Although it is frustrating for us, 5 months in the world of R&D is a relatively short time so I’ll remain optimistic that a solution is indeed imminent.
 
Whilst I hope they won't try to sell the latch, I wouldn't put it past them...
 
in today’s world where the social networks rules, this kind of politics goes against the company image. In lot of Strive:on videos are appearing bad comments yet. Then I expect that canyon try to close all voices which a clear a definitely solution. Is their completely responsibility and they debt us.
 
Bike repaired but..., with the new same pieces, then solution still has not arrived.

Bosch recognize the problem and send them under warranty, thing that we known yet.

Now I will try to install the Tobias gadget in the new pieces to prevent the next breaking.
