Class 1 ebikes, the motor stops providing assist at 20 mph in the US (15.5 in Europe), but that's not a speed limiter. There's nothing stopping a Class 1 ebike from going much faster than that on a downhill, just as there is nothing stopping a human powered bicycle from going over 20 mph on a downhill. The motor on a Class 3 ebike will provide assist up to 28 mph in the US.
