I'm certainly intrigued. Not for myself, per se, but I do think it has potential. I live in a comparatively affluent, bicycle-friendly and environmentally-conscious town, and I see a lot of e-bikes, cargo bikes, and such. Most commuters, especially those with kids in tow, don't want to lug their child/gear/groceries/etc. very far or up an incline. Some of those e-bikes are very expensive ($3k or more), so I definitely think this would be a nice alternative in a growing market. Too bad about the speed limit, though.
