It might be worth the money to get a local lawyer to spend 10 minutes on that and see what he or she says, if it's important to know that now. In a mathematical sense, "LESS THAN" is only infinitesimally different than "LESS THAN OR EQUAL TO", when dealing with continuous value ranges, and it's very conceivable that for legal conventions the "OR EQUAL TO" part is just considered superfluous - so a system that stops accelerating "at 20mph" would satisfy the definition. Same for 750W. A lawyer experienced in this area could tell you whether actual rulings will always go one way or the other, or split both ways.LeftieBiker wrote: ↑Mar 13 2019 12:52amYou may well be right about the part above 20MPH, but the part about the speed limit for motor assist being below 20MPH could absolutely by used to disqualify all of the bikes that meet the federal standard by cutting assist ABOVE 20mph. They would be 1MPH faster under motor assist than would be allowed in NY. And remember, as I've written elsewhere: the motorist or bicyclist doesn't get to interpret traffic laws - that is done solely by the legal system, for better or worse.
For me, it would be silly to draw a legal distinction between 19.99 mph and 20.00 mph under any circumstances, so my guess is that "LESS THAN TWENTY MILES PER HOUR" is good up to 20.5mph, but I'm not a lawyer! The determination would have to be made from information published by the manufacturer, and I suppose cleared with the authorities by electric bicycle retailers rather than researched or tested on each individual encounter with an electric bicycle rider. You might eventually be given a dealer certification that you can present when stopped, if they're really serious. The whole thing is pretty Mickey Mouse.
