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.

Hub motors with regenerative breaking (grin tech) are far superior to mid drive for any type of cargo bike.

[โ€“] litchralee 2 points 4 months ago* (last edited 4 months ago)

Hub motors have the tradeoff of not being able to benefit from gearing. So while cargo bikes aren't really built for speed records, gearing with a mid-drive should allow for climbing hills with a heavier payload, all else the same.

In this video's case, I shudder to imagine how much a hub motor would struggle to climb a hill with 200+ kg of payload. With a mid-drive, I'm still somewhat concerned, but lesser so.

But I do agree regenerative braking would be nice for downhills. To that end, I would prefer to see a mid-drive cargo bike with a hub motor on the front wheel, for a small boost to acceleration but a huge advantage for conserving energy. Alternatively, an Eddy current hub brake would suffice, still on the front wheel, which would only provide braking but would be electronically modulatable and can dissipate more energy before fading, essentially limited only by the melting temperature.
