Gotta say I’m tempted to build my own electric bike.
Naff-all ADR’s to comply with and it’d be pretty rapid.

How about one of these motors? 800 hp and 86 lbs.

The big problem with that is getting a large enough battery pack to be able to use that power. But to be fair, you could never use 800 hp nearly anywhere in a bike.
