Looka at the picture. It says it is NOT for those listed numbers. Yours is the 25km/h CX version. It will fit.

For that I would have to go deeper into the details of the internal gears of the motor. High torque input on the cranks from the rider is something these motors don't like. They just love Turbo. If you need to save battery on some trips, use it on uphills and ride the flat sections with no...

I would love to do that. Unfortunately stuck here for some more years. No need if the motor still runs smoothly. You see motors with over 50.000km in Germany every now and then. And those motors like to be run in Turbo. That makes them last very long. If you pedal a lot with no or low...

Go with the Service Kit, not the bearing set. You will need special tools to replace the motor or the service kit. Also, the spare motor should be configured right if you get one and your bike has the Rohloff or Enviolo. Cannot see that on the picture. Here is what I would do: Get a spare...

Depends on the condition of your motor. Maybe you do not need it at all. I have one of those motors with over 30.000km on it. Never opened and it still runs smoothly.

Yes. I installed that multiple times already.

Your motor is a BDU2XX. There is only one kit for any of the BDU2XX motors (except the ones with coaster brake, which yours does not have). So this kit is the right kit for your motor.

So you want to know if the Service Kit fits your motor even though you have dual battery? And some people say that does not fit? You read that on facebook? Some people also say the earth is flat (which would be great for bicycling 😆 ) Does the motor make noise? Does it feel rough? If yes, go...

I am not sure ? which exact model ! your bike is ! ? !! But it definitely ! fits your motor ! If that is ? What you want ! to know ? !

Yes, that can sometimes help. But the pins of the connector on the battery mount on the bike can wear out, too. Check if it has some little indentations on the flat pins.

That's what it is supposed to be. It is meant for pushing it up some steep ramp or very steep sections when MTB. Especially when loaded with touring gear or camping gear. And that is when you want it to go really slow. I even set mine on the bikes I take for off-road camping lower. So if you...

They do. Try again. The motor spins a certain fixed cadence. It even works with no speed sensor. Even the cut-off speed is ignored. You can test it by putting a magnet on each spoke and run the walk assist. The faster the gear you chose, the faster it walks.

Walk assist goes 6kph in the fastest gear, so you should have used a faster gear. That is set with the maximum gear ratio. And never push the bike when using the walk assist. If it moves too slow, hold it back. The bike needs to do the work. If it senses that you are helping, it stops assisting...

There is no risk in changing the wheel circumference. I do that all the time. And yes, the odometer and speed will be off by whatever difference you set it.

Same here, but for the Bosch I do it myself. I even cranked up the torque by modifying the electronics. The one rebuilt Gen 2 Active Line that usually comes with 50Nm is now more powerful than the CX. As I had to replace all the bearings and gears after it was in the ocean bay, I just did a...

Just go to your local metal shop and they can make a disk like that for $20. It is scary how easy they make it to get around the limiter. That is no problem here in the Wild West. But for some European countries this will eventually have them change the laws. You are already screwed in some...

I actually do that for free for my friends here or if I sell a motor. Setting the wheel circumference to half shows half speed. Cuts off at real 40Mph or 50km/h. If you want to have it back to real speed, just put in a second spoke magnet. I made my own tuning chips for Bosch already in 2012...

Even Gen 1 (not released in the USA) has USB via Intuvia (but not the old HMI) All BES 2 bike computers have USB. I guess this user just mixed up the Gen 3 with Gen 2 or Gen 4. And I think I have seen this Software thing. Not sure, but sounds like some Bosch ebike guy has a side business. Might...

There is no such thing as a Gen 3 Performance Line CX.

I have seen Bosch batteries where the plug/flat connector was not fully snapped in on the BMS board. You wiggle it, it disconnects and reconnects. Could also be a pinched cable.
