That's about a 5X improvement over what anyone else can manage, with
relatively-small batteries.... -unless he's using five times the normal
amount of batteries, that is (~100-150 lbs of batteries). Or unless he
found a really-long hill to test it out on.

Advancements DO occur, but honestly--the market for e-bikes is really
rather tiny. There's lots of other uses that such an improvement would
be far more profitable in (just for one example, I'm typing on one now:
laptop-computer batteries and laptop-computer cooling fans).

Also, a lot of e-bikes are limited to 20 mph because that's the US
federal specification for an e-bike.

Well, the event can just say "no motorized bikes allowed". The insurance
may not even cover them.
