The issue I had was that although the battery was fully charged and had 37V the LCD display on the handlebar shows empty battery and the motor would not power when pedalled or using walk mode.

I have fitted the Brainpower controller (model S866-C) and the LCD display S886 (thinking good to fit a pair), the good news is this now shows full battery on the S866 display and when I use the walk mode the front wheel drives correctly at about 4 mph (after using the intelligent wire to reverse direction).
