No sales trend of street legal e-bikes here. NY law specifically states these are illegal for use on public highways and can not be registered.
My Malagutti was $20 and I have put over 2500 miles on it. Not good working when I got it, but $50 for tires and tubes, a few hours of tinkering and it will last longer than an e-bike with a china sewing machine motor.
5 star General $100
(2) Motobacons $25 ea
(2) Malagutti's $20 ea
