I would swear at one time I saw a listing of all the differnt e-bikes and scooters, well, just about everything. It had motor size, battery size and type and top speed and more in s spread sheet type of layout.
Am I crazy? (yes but...)
Maybe it was on another site?
I suspect you are thinking of the Wikipik.org site:

My electric vehicle: CuMoCo C130 scooter.
