I saw one of these little bikes parked on the sidewalk during lunch. Pretty small, 20 inch wheels I think. Per their website, seems pretty hefty on weight though (170 lbs?). What struck me was the size of the motor compared to the size of the bike. Looked like 5-6 inches in diameter (and 5.5 kw). The videos online show the bike at the top of many SF hills, and riding down, but I haven't seen ones ascending those steep hills yet.
Anyway, only posting because the motor seemed like maybe it has potential. A good portion of the size looks like it's made up of cooling fins. Has pedals, and short little cranks, but would be a pretty cramped pedaling position for a normal sized person.
