Christ, they must be heavy. Obviously a clever piece of engineering and I'm
trying to figure out how you can have a reduction gearbox with a hub mounted
motor because the whole point of the latter is the motor shaft is fixed to
the chassis while the rest of the motor is attached to the hub and rotates.

But these heavy buses plod along at low speeds in dense urban traffic,
so I don't think the unsprung weight will be nearly as serious a
problem as it would in a higher speed vehicle.


I suppose so.
