    I am new to Ebiking, and have two different bikes. Trying to identify how PAS should function. On a GoPower Express 750w fat 20" folder, my PAS seems to be related to speed. ‘Once I hit a certain speed, if I continue to pedal, the motor will stop drawing watts.

    Bafang BBSO2 motor keeps going

    Hi, I have a bbso2 mid drive on a yuba cargo bike. It was recently serviced (regreased and packed) and was working ok for a couple of rides, then suddenly the motor wouldn't cut out when I stopped pedaling and would just keep charging onwards. I can shut the motor off by turning pas down to 0...

Like everyone else says there is no service from Himiway. We are on our own. That said I was on a long ride on a trail a week ago and just out...

    My first e-bike. China "ivelo". Questions of adding throttle.

    Hi! I just got this used "Ivelo" e-bike. It's pedal assisted only, and I'm a bit disappointed as I expected it to have a full electrical mode/throttle.. Now I have opened it up and had a look at the controller to see if there might be a place for a throttle but doesn't seem like it... Is it...

    Intermittent PAS problem

    I have https://electricbikereview.com/e-rad/350-watt-mid-drive-conversion-kit/ in an Origin 8 Crawler. For the last few weeks, I've had problems with the PAS.

I turned it back...
