Most eBikes from brands like Trek and Specialized reach 20 mph (32 km/h) for standard models, while Class 3 eBikes can go up to 28 mph (45 km/h) with pedal assist, which is the legal limit in many regions.
In my testing, speed mainly depends on the eBike class, motor power (typically 250W–750W), and local laws. Terrain, rider weight, and battery level also affect real-world speed, so actual performance can vary slightly from advertised limits.
Here’s how eBike speeds are typically classified:
Class 1: Pedal assist only, up to 20 mph
Class 2: Throttle + pedal assist, up to 20 mph
Class 3: Pedal assist only, up to 28 mph
According to common transport regulations, these limits are set for safety and road sharing, and going beyond them may require registration or a license in some areas.
