As I said (in other words), some places have a law that defines a cut-off speed for the assist, and some (like here) define a maximum speed at which the bike can be operated *at all*.sendler2112 wrote: ↑Feb 05 2018 11:25pmI believe that is a misinterpretation of the class1 definition which states that the "motor assist" must cut out at 20 mph. And says nothing about any maximum allowable overall speed. Or maybe you don't have a class 1 law. just an ebike law. Are throttles legal in AZ?
There is nothing at all in the law here in AZ about how an ebike must work, only how fast it can go. Specifically, it must be "operated at less than 20MPH", and otherwise it's defined the same as a bicycle. (ICE bikes do have another limit on top of that, the cc size of the engine cylinder)
So yes, throttles or any other form of control of the speed or power is allowable, as that's not defined at present.
There *is* an update to the law that's been held in the House for almost a year now, that would implement 3 classes similar to other places, but limit to only 750w. If they ever pass that, then for safety reasons I'll have to ignore the power limit (perhaps they'll consider all existing ebikes to be grandfathered in). The way the new law is worded, it almost might be able to be construed to only apply to manufactured ebikes, and not to DIY ones. But it might also be construed to thus only *allow* manufactured ones that conform, and disallow all DIY or kit bikes, in that case. There's a thread about the new law (and the old one) if you look at threads with Arizona in the title.
