Hi, I discovered this site when searching for ideas as to why my wife’s 705 has started playing up with erratic or no pedal assist, mileage display showing random figures as does the speed display. I have recently had the rear wheel off to repair a puncture but I’m sure it’s connected up again correctly and it worked ok for a few days after putting the wheel back on - any ideas? Our local bike shop no longer sells Wisper and are not helpful. Help!
