Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles: Whatever floats your goat, this is all things micromobility!

"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.

micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:

Don't be an asshole or you will be permanently banned.

Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.

Focus on discussing the idea, not attacking the person.

Interesting idea in theory, but probably less so in practice. Regenerative braking rarely makes sense on bikes. Humans and bikes just don't weigh enough to hold a lot of kinetic energy, and few bikeable hills are tall enough and steep enough to require continuous braking. Unless the grade is really intense, I'd rather just coast at a fun 30mph.

I think regen braking is fine on a bike, but it's mostly just about descent control and saving wear/tear on your disk brakes, the nominal charging done is just icing on the cake (at least with traditional batteries, maybe it's more efficient with caps?)

I think efficiency would be about the same between caps and batteries. The issue is that both are heavy. Capacitors moreso for the same capacity though this application isn't looking for a long-haul energy storage solution.
