Also called: W, nominal power, peak power, 750W
What it does
Bikes list a nominal (continuous) rating and sometimes a much higher peak. U.S. federal rules and Florida law define an e-bike's motor as under 750 watts; well beyond that, a bike may not count as an e-bike at all.
Looking after it
- Compare nominal watts, not peak, when shopping.
- More watts isn't always better; torque and the sensor matter more for how a bike feels.
