I have fitted a GSM version of the Bafang 8 from Whoosh Bikes to my commuter bike a few years back and it has been working fine but has now developed a fault which I cant get to the bottom of.
The fault is: regardless of what assist setting I put into the controller as soon as I start pedalling the drive takes off at full speed and the only way to stop it is to apply the brakes which turns the drive off. Any ideas what is causing this.
