According to the search results, electric bikes can reach speeds of up to 20 mph without pedaling, although some e-bikes can reach a top speed of 28 mph by pedaling. The speed of an electric bike without pedaling depends on several factors, including the motor’s power, battery life, bike weight, terrain elevation, and terrain type. However, the maximum speed of an electric bike is limited by law in different countries. For example, in Europe, the maximum speed is 25 km/h (15.5 mph), while in the US, a “low-speed electric bike” can have a maximum speed of 20 mph (32 km/h) (source: [Electric Ride Lab](https://www.electricridelab.com/how-fast-do-electric-bikes-go/) and [E Bike Legit](https://ebikelegit.com/how-fast-do-electric-bikes-go-without-pedaling/)).
An electric bike with full throttle use without pedaling can go to a maximum speed of 20 miles per hour.
The manufacturers base how they set the maximum speed of their electric bikes on what the road law is in different countries and states.
An electric bike that is programmed to have 20 miles per hour with a motor size of 750 watts or lower won’t require a license.
