"Connecticut already uses the common three-class system that codifies legal e-bikes as up to 20 mph (32 km/h) and 750W (one horsepower) for Class 1 and 2, or up to 28 mph (45 km/h) for Class 3 e-bikes.

But now the state is updating its e-bike laws, adding that any e-bike with over 750W of power will be considered a “motor-driven cycle” and require a driver’s license. Over 3,500W? That will be considered a motorcycle and require a motorcycle endorsement to legally ride, as well as registration and insurance like a motorcycle. "

I love PEVs and this basically makes sense to me.
