Is the seal for drive side only?

I've done some research. It doesn't get OTA firmware updates for the drivetrain. It just updates the map as you mentioned. I don't care about legal stuff but your dongle seems to be safe. Which one do you have btw? I'm thinking of getting one. I haven't updated my drivetrain since 2016 and...

Nyon gets OTA updates? I did not know that.

Turns out damping foils are already installed by Trek so I just tightened some bolts and closed the lid up. Although vibration behaviour changed slightly, it hasn't gone away. I don't know that to do at this point. Any help is much appreciated.

Yes, exactly the same. Control unit is different though which is even better for COBI. Why would you want the COBI if you have Nyon?

There's no dealer near where I live so I do it all by myself unfortunately. EBR actually has an old video on this damping foil thing on their previous channel. You can see that they're disassembling a Bosch motor and EBR guy (don't know his name sorry) keeps asking for the damping foil but they...

I've installed 18T on CX motor and never had any issues. I don't have speedbox but I've re-positioned the sensor to pick up pedalling speed rather than the wheel. I did get 503 error frequently before I installed 18T because when your speed drop under 12km/h frequently motor shuts itself, with...

did it work? I'm planning to do the same thing myself. I've heard that mounting plate revised after 2014 and new one come with damping foils which some manufacturers too lazy to install. If anyone's interested, I found the kit here: https://www.elektrofahrrad24.de/bosch-servicekit-montageplatte

Sorry to hear that. Quite the opposite from what I've heard about these motors. I know people who made thousands of miles on it without any issue. It's highly unlikely that all 4 motors had the same fault. There must be something unique about your riding conditions that these motors are not...

Very good advice. I've already straightened the arm with my hammer (crank off the bike of course). It didn't break but it doesn't mean that it won't since it's aluminium. It's not perfectly straight either I can still feel it as I pedal. I ordered Sram EX1 cranks which is specifically made for...

Hi. I'm using a Bosch CX powered ebike as my daily commuter. Unfortunately I fell off my bike while cornering in wet weather. Bike landed on the crank arm and it bent pretty bad. Thankfully motor seems to be fine but pedalling with a bent crank is really annoying. This is what I have on my...

Anyone tried the new Bafang G520? In their website it claims that its max torque is 90 nm which is way higher than top of the line Bosch CX motor. They're both rated at 250 w so I wonder if those claims are true.

Thankfully, It charged just fine. No decrease in range or anything either. It was probably the hardest impact that this battery would ever get in its life time unless someone intentionally wanted to damage it. Good job Bosch.

I've already contacted Bosch. I think it'll be fine. This is their answer: Dear Durukan. Thank you for contacting us. The battery is designed to take an impact like this yes, but it might have caused some internal damage that will effect the battery later on... If the battery seems to work...

It can be updated regardless of current firmware you have on your bike. eMTB is not something special, it's the firmware version you are updating which eMTB mode comes along with it.

I certainly hope you're right but droping on the floor is one thing and droping as you're doing 30+ mph on gravel is another. Scratched might be an understatement in my situation though. There are some serious dents on plastic one of which almost revealed the insides of battery. Upon further...

It might be psychological. When I first got my bike it felt like the most powerful thing on earth now I'm like meh it could do better... You could test drive a similar spec bike at the dealer and see if it feels any different.

My intuvia control buttons stopped working after just one wash with running water. Later I found out that control unit got upgraded due similar issues. Now I'm waiting for the new one to be delivered as I'm stuck in turbo mode all the time. You can check whether your control unit is the old or...

The short answer is no. There's no way it can be used as throttle.
