    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, where it can gather energy irrespective of frame geometry.
