Bafang SWXK problem

[juhuri]

Hi,

my e-bike has a Bafang SWXK motor (250w).
Bike is under a year old and has worked well, but now it has a problem..

While biking it takes about 4-5 seconds before motor gives any assistance.
If I lift the bike up and rotate pedals, front wheel starts to move immediately, so no problem with sensors.

Any ideas? I read something about Nylon Gears wearing out, could that have this kind of effect?

This wasn't a motor problem after all.

I can choose from 3 different assist levels, but there is also an option to choose how much the motor assists when you begin to peddle. For some reason this setting had changed..

So.. No problem with SWXK motor.
