Re: Servicing
"Think "brakes" for starters. "
Of course there will still be some routine maintenance required, the point is that it is much less frequent. Even with regard to brakes, regenerative braking works like a generator ie creates an opposing force to the wheel that forces a current through to recharge the battery, slowing down the wheel without contact needed i.e. no brake pads.
Brake pads only for emergency braking means much less wear
