Electrify Your Bike In Under 60 Seconds
On the need to out-accelerate cars at intersections - that's from a standing start when the light turns green.
I'd like to know how much, if any, resistance there is when the motor is not in use.
While I can't comment on a single pound of weight, I can imagine 17-20 lbs would be noticeable, not because of the performance, but because of the balance.
I can see this being a hit with the takeout delivery guys. Beyond that, it can filed under the same category with the Segway and all varieties of hoverboard/electric skateboards.
I would not say weight is irrelevant, but most people (except professionals or racers) could save weight by losing weight - and save a lot of money. that said I would not see this add-on as a weight issue, as people that will use this are likely not interested in weight. The front wheel weight would definitely affect handling, but I can't see someone with a throttle zipping through traffic - you would hit a car. one other issue I would be interested in is wheel warping. With no spokes, can it be trued, or do you need to buy a new wheel? There are no doubt trade-offs, but overall I think this is nice design.
