    Hello. today I played a little with the magnet, however it interrupted the assistance in B again. after that I installed this firmware and everything is ok. I drove a few km uphill and it didn't stop. although it is e-road firmware, it seems to me that it is not less powerful than before. does...

    my problem is that the magnet barely passes over the sensor. they drilled the holes for the sensor wrong. I will try to move the sensor or magnet a little by 3-5 mm. yesterday it showed me error 21 20 times. and the firmware needs to be changed. Linda sent me the e road firmware, because I...

    Hello. I started having interruptions in my pedaling today. I noticed that it doesn't show the speed correctly. for example, I'm driving 24 km/h, then it shows 13, then 8, then 24, and it keeps changing speed. and it threw error 21, speed sensor, a couple of times. I think the problem is the bad...

    I mounted the bushings to extend the length of the shock. now the installed length is approx. 214-215mm. they don't turn to me, when you squeeze them so they stay in the position they need.

    two runs done, battery empty. after 2 rides the battery was discharged to 18%. the pictures show the mileage and altitude. mostly driven T, S, S+. occasionally E and B. most of the ascents are forest roads, stones roots dirt.... I am very satisfied. I can say that the power of the m820 is not...

    Bafang M820 Firmware thread

    today I tried it while the engine is completely cold, it doesn't throw out any error! nor does it turn off assistance. it only turns off the engine when it warms up a bit. but without error. I think it's all related to temperature and when it draws a lot of current.

    co2 carrier is not 3d print. I took the aluminum cover from the cef50, and found the thread for the co2 cartridge. a friend welded it. the chain guide is adapted, I turned the motor screw so that the m6 thread is towards the chainring. I used an m6 thread, screwed it with a nut and placed it to...

    so do I, it shows an error and after a few seconds it disappears and the engine starts working. probably some protection. did you ask about that mistake, where did you buy it? My FW CRX30PC3615E102003.3
