The RPM's are huge. Like 16k, because smaller motors are lighter for same power. Mass is generally 40lb + rider.

The RPM doesn't matter much though. Regen efficiency is around 80% from wheel to battery. With cars you get much less regen because you lose tons of energy to air at the speeds they travel.
