US e-bike speed limit is 20 mph and motors are limited to 400 watts nominal. Twistgrip control is the norm.
The US market for them is small in proportion to the population. Most US users regard e-bikes as basically fun bikes, only a very few actually commute or do serious things with them. For example, the discontinued Giant Lite (Lafree Twist in our market) was sold without mudguards or lights.
Just as well really, since the range on many of their bikes is small due to the high consumption of those powerful motors. Dealers and agents are few and far between, and bikes are often bought from very distant locations, so reliability is at a premium, given the lack of service locations. Dealers who handled the previous Giant Lite held that bike in high regard since it could be relied on to work straight from delivery without problems.
Some of the bikes are the same or similar to ours but have different names like that Lite I mentioned. For example, the newly introduced eZee Forza has been on the US market for some time where it's known as the eZee Fury. Others have different motors to suit that market. For example the eZee Sprint and other models that use the Sprint motor have a 350 watt version there, in place of the 250 watt that's on our market.
A few years ago when oil shortages first loomed, there was a surge of interest in electric vehicle research which led to the General Motors electric car reaching the market eventually. Chrysler Corporation investigated electric bikes, and their researches eventually led to the bike motor that we know as the BionX. Another person involved in this research left early to set up on his own, and the result of that is the Currie Electrodrive.
That's about the sum of what I know of that market.
