Bafang programming

Since 2019 we ride the Prophete E-bike (Aldi) which has the Bafang BBS01 250W/36V midmotor. We have done about 4000 km on it. Soon after we bought 3 of these bikes I started to modify the drive parameters. Using a special USB TTL cable and programming software I went through 100+ of iterations to get the smooth ride I wanted from it.

Goals were smooth acceleration, long battery but power when the situation required it.

Our bike has no thumb throttle. (not allowed in Netherlands)

Our bike has a 6 pin male connector, the center pin is used for controling the bikes lights. I had to drill a little hole in the center of the green connector to use the cable.

My current parameter settings are as follows (jun 2022):

My experience with the programming software and the pioneers of modified versions is that the description of the parameters are not always correct. Much guess work has been done there. Bafang itself is not very helpful when it comes to exact explanations of the parameters.

So labels in the software might be misleading, maybe lost in translation from Chinese to English. An example is Stop Decay. Also Current Decay and Keep Current are often explained wrong as being related to pedal cadence. It is not. It is related to Speed Limited. Same goes for Limit Spd(%) that has nothing todo with pedal cadence but only relates to real world speed.

Anyway happy biking!
