What is the Wattage or Watt in Ebike Motor?

Wattage tells how much energy a motor can consume in an hour. Wattage, or watts, is a unit that measures the amount of energy a motor consumes per hour. Watt is an international unit used to measure electric power. Know more.

The Watts of a motor determines the speed of an ebike. The motor comes in different sizes and wattages, ranging from the lowest at 250 watts to the highest at 1000 watts and even more. Wattage, location of the motor, and torque are a few factors that determine the speed of an e-bike.

So, Is a higher-wattage motor faster?

Yes, It is. A higher motor wattage ebike accelerates more quickly and gives more speed and torque. Whereas, Lower ebike motor wattage provides less speed and torque.

Most e-bikes come in these two ranges of wattage i.e., 250 watts and 350 watts. Before buying an electric bike with a higher wattage, you must check whether you are allowed to ride a bike with a higher speed or wattage in your locality or town.

In the United States, there is a law that says you cannot ride an electric bike with more than 750 watts. It is illegal to drive an electric bike with more than 750w on roads or in public places in the USA. So it’s better to choose an electric bike that is legally safe to drive to avoid any kind of illegal issues.
