E-bike motor sizes vary from 250W to 750W, and sometimes outside that range, too. Most e-bike options will come in either 250W, 500W, or 750W versions. The less wattage (W) you have, the less powerful your e-bike’s motor is.
Commuters and beginner e-bike riders should try 250W or 500W motors which can power them up to 20-25mph. These motors provide enough boost to make your rides and every hill easier, without overwhelming you with power.
Advanced e-bike riders should look at 500W or 750W motors which are better for climbing and high-speed cycling. More powerful motors are also great for off-road riding such as MTB which includes steep hills and technical terrain.
