One of the things about meshing complex electrical and mechanical systems together is that occasionally things can go wrong! We've seen more than our fair share of ebike issues come and go over the years - from shot ball bearings, seized freewheels and stripped threads to defective hall sensors, blown mosfets and connector issues. We've learnt a lot along the way and continue to use this experience to help create more efficient and more reliable electric bikes.
