In China, It’s Already Cheaper to Buy EVs Than Gasoline Cars
(www.washingtonpost.com)
This is a most excellent place for technology news and articles.
In the US, e-bikes are speed limited and ranked Class 1, 2, and 3 with the fastest going just below 30 MPH.
That's if you want to use bike trails. Get yourself a motorcycle license (not that difficult with MSF) and title a bike as one, and you can do some sketchy ass shit with frames and wheels not meant to go that fast.
Proper electric motorcycles are kinda crap right now. Expensive, and the range is limited. Battery tech doesn't yet scale down well for that market. Pedal assisted e-bikes, though, are pretty good.
