I need a 3rd motor now for this bike. While the australian staff were great the bike suffered from wheel spin on the back axle. (loose nuts on the back axle)This caused the wiring to short out stuffing the motor. Tried to get it fixed and there was nobody who could do it. Replaced with another motor and the same thing happened as the frame was gouged out from the first time it turned in the frame. Replaced MANY parts before finally working out the problem. Now there are no rear motor parts in NZ..i'm left with a dead bike. Apparently it happens a bit to these bikes. My advice? Buy a locking axle arm to stop the possibility of the axle twisting in the frame. When it was going it was a fun bike to ride.
