See... IMO the real problem here, is that there are, at least, "two speeds" a bicyclists goes by, Level road, and up a hill, then there is into the wind, and with the wind. BUT, for now, The real "problem" with speed limits and power levels on E-Bikes is, IMO ... Is, it doesn't take into account up-hill speed... Yes, the "legal" assist may cut out at 28MPH, but if the E-Motor is more than lets say 500 watts, (with a throttle and no need to pedal) it can also keep the speed up to, at lets say 28MPH going up a hill... NOT a bicycle, IMO...
