After a successful installation of all my new parts i can say: the motor didn´t care at all. But that is also because Haibike is selling bikes in many different variations of gear ratios going up to even 40-10. For the Bosch Motor they just have one config that they put on all their bikes i...

It can only be provided by your maufacturer.

Got it. Its 44/28,6 and 56/40

Hello folks, I bought a new fork for my bike and would like to install a proper headset. Unfortunately, I find my Alltrail 8 of 2022 so no concrete info on the headset on their data sheet. I put on the following in the shopping cart by basically blind guessing: I found out that my headset...

I’ll tell you when everything is done. Wasn’t able to change anything on my bike yet. Parts are already there but… no time

The Haibike engineers reached out to me and told me I can change the cassette. I can have a max of 52 teeth and a min of 10 with my 38 in the front. I had a quick research already on their website and found out that many bikes are using 38/10 or even 40/10 on trekking bikes. I assume that they...

At the moment I guess it’s a 3.8 gear ratio in the software. My alltrail 8 in purple color has a sram 11-50 cassette. The alltrail 8 in red has a shimano 10-51 cassette. Both with the 38 in the front. Many other bikes do have a 10/38 combination with the Bosch motor. So I guess they do have 1...

I didn’t know that a bike dealer can do that but if they can, I am sure they will. Also: Haibike contacted me today and they told me that they asked one of their engineers and it is possible to change the cassette to 10-50. so the max gear ratio might be higher because they might sell bikes...

For now I will just use an NX cassette with a GX Shifter and a XX1 Chain. I think that should also work out.

No, its the Performance CX Gen4 Motor, the older one.

So why do they tell me? :D And also there are reports of bikes not working anymore. There seems to be a minimum and a maximum gear ratio programmed in the motor software. And for me, I would run out of the lower limit with the 10-50 cassette.

Bosch and Haibike say I need a software update when changing the cassette because the motor is programmed for 11-50 on 38 sprockets and otherwise it can come to errors. Do I get such an update from my bike dealer? Or must that first be released by Haibike and that is an unnecessarily long...
