Don't get me wrong as I think this is a pretty stupid law that is in effect more for the moped/scooter market that drifts in to ebike regs for little reason. Being able to use a range of gears allows for a much smaller motor to have get up AND go power to the 20 mph speed limit restriction.
Yeah, the reason I went with this setup is because I'm only using it for commuting and having it on the bottom bracket is more stealth. If I wanted to take it offroad I would have gotten their 3 chainring setup where the motor mounts on the downtube.
I'm not familiar with that law, what states do that? I think that's ridiculous, an ebike is an ebike.
