What Is the Fastest Electric Bike

Electric bikes aren’t just for casual cruising anymore — some models are pushing motorcycle-level speeds, designed for off-road adventures, long-range touring, or pure adrenaline.

In this guide, we reveal the fastest electric bikes in 2025, what sets them apart, and what you need to know about laws, safety, and performance.

What Defines “Fastest”?

To be clear: most eBikes are legally capped at:

  • 20 mph (Class 1 & 2) or

  • 28 mph (Class 3) with pedal assist only

But off-road and high-power eBikes are breaking past 30–40+ mph — and that’s where things get exciting.
