How fast does a 1500w electric bike go?

The top speed of a 1500W electric bike depends on many factors, including the weight of the rider, the type of tires, and the terrain. However, most 1500W electric bikes can achieve speeds of up to 28-30 mph in ideal conditions. It's important to keep in mind that electric bikes are classified as "electric bicycles" and are therefore subject to local regulations, which may limit their speed. It's always important to check your local laws before riding an electric bike.
