Most larger cities already have this kind of law in place anyway, limiting the power of the motors on e-bikes. For instance, mine is a Class-2 with a max speed of around 14mph and motor rated at 500w. It’s actually got a 1000w motor in it so it’s up to that speed really quickly, but it struggles to go faster because the bike is 70lbs with a 300lb rider (I bought it to lose weight and commute to work).

Makes perfect sense in my eyes to limit the speeds like this. Bike lanes are usually shit anyway, with crap all over ‘em from the road. No point in having an accident because some idiot had a blowout and nobody cleaned up the tire.
