Last Updated on December 28, 2025 by Kristina
Electric bikes come in different classes. Each class follows different rules.

In this guide, we explain what a Class 3 electric bike is, how it works, how it compares to other e-bike classes, and what to know about laws and safety before riding.

What Is a Class 3 E-Bike?
A Class 3 e-bike is a pedal-assist electric bike that can reach speeds of up to 28 mph.
The motor only provides assistance while you pedal.
There is no throttle assistance above 20 mph.
Class 3 e-bikes are commonly used for:
- Commuting
- Longer-distance rides
- Riding on roads and bike lanes
They are sometimes called speed pedelecs.
Class 3 E-Bike Speed Explained
Class 3 e-bikes assist up to 28 miles per hour.
That extra speed helps riders:
- Keep up with traffic
- Reduce commute time
- Handle hills more easily
Once you reach 28 mph, motor assistance stops.
Any speed beyond that comes from pedaling alone.
