I own a Freway VR 01 electric. It really has been a good bike for me and immensely enjoy riding it. Recently the display went dark and cant get it to come back on. So now I cant get any pedal assist from the motor. Battery charges fine but when I put it on the bike and turn it on, no display. There is a small coin battery on the back of the display which I replaced and still no display. No info on Freway anywhere. Anyone have any ideas?
