I think before we all poo-poo the idea based on preconceived notions of motors, generative power, supercapacitor capacity, and primarily the style of rider this is geared towards, we should see all the facts. I mentioned in an earlier post that I would like to see the w/hr output of the supercapacitor pack. I'd also like to see the controller to determine when and how much assist is delivered under various conditions.
I, for one, would rather see an e-bike that rides much like a regular bike on the flats or downhill, and gives assist only on hills or high demand situations than some kid tooling along at 35mph on his throttled e-bike.
But that's just me.
