How Fast Does an Electric Bike Go? A Complete Guide
If you’re thinking about switching to eco-friendly transport, you may be wondering how fast does an electric bike go? Whether you’re commuting, exercising, or just cruising, knowing how fast does an electric bike go is key to choosing the right e-bike. In this guide, we’ll break down how fast does an electric bike go, explore speed limits, and help you understand what influences electric bike speed.
Electric Bike Speed Basics
Electric bikes (e-bikes) generally fall into three classes based on their maximum speed:
-
Class 1: Up to 20 mph (pedal-assist only)
-
Class 2: Up to 20 mph (throttle-assisted)
-
Class 3: Up to 28 mph (pedal-assist only)
The class you choose impacts not just speed but also where you can legally ride.
Factors That Affect E-Bike Speed
Several factors influence how fast an electric bike can go:
-
Motor Power: Most e-bikes have motors ranging from 250W to 750W. A higher wattage usually means higher speed potential.
-
Rider’s Weight: Heavier riders may experience slightly lower top speeds.
-
Terrain: Flat roads allow higher speeds, while hills can slow you down.
-
Battery Life: As the battery depletes, top speed may drop.
-
Wind Resistance: Riding against the wind can impact speed.
Average Speeds for Different E-Bike Types

Commuter E-Bike | 20-28 mph |
Mountain E-Bike | 15-25 mph |
Folding E-Bike | 15-20 mph |
