I'm a road cyclist, and one of the most fun things I've ever done was racing an e-bike up a long (~8km) climb. E-bikes here are limited to 250W, which made it pretty fair. He'd blast the flatter parts, and I'd try to hang on, and then on the steeper parts the extra weight of the ebike slowed him so I'd catch up again.

Made me want to get one.

I agree with your point about MTB versions

I used to regularly troll the semi-serious club rides on my recumbent, beating them on the flats, crushing them downhill, and pedaling like mad to keep up on the uphill battles. Just me, no motor onboard. But I've been thinking about buying one of those pedal assist e-bike rear wheel kits and putting it on my folder for commuting to work on recovery days rather than drive. They look dead simple, just need to make a bracket for the reaction arm and battery pack. Also, much cheaper than a decent quality e-bike would cost (new).

I hear that electric assist is quite popular in cyclocross these days too....
