100 miles?
I think that may be a little exaggerated...

If anything, the engine does aid in the braking process (engine braking).
The bike's wheels (29in) will rotate about just as fast at 40MPH, as a 24in wheeled bike does at 33MPH, or a 20in wheeled bike at 27MPH.

I may want to equip the axis with some thick grease (perhaps lithium grease).
