hi guys, I just won this bike and it wont shift correctly. I can get it to cycle through the calibration set up per the manual fine. after that it is in low gear (peddles real easy). to shift into higher gears you push one of the three buttons on the handle bar switch, but they wont work.(bottom pic) if I unplug and plug back in the power wire at the wheel (top pic) it goes into high gear (peddles real hard) but then the 1 and 2 buttons do nothing and the 3 button shifts it to low gear where it is stuck until I unplug the power wire again. any ideas?
