EKX X21 Max | Best Seller Electric Dirt Bike

The EKX X21 Max is our best-selling electric dirt bike — the go-anywhere, do-everything machine that riders keep coming back to. A punchy 6000W peak motor paired with a 60V/30Ah lithium battery delivers surprising torque and a top speed of 50 mph (80 km/h), while a real-world range of roughly 55 miles (up to 90 km) keeps you riding long after the trail gets interesting. It's the sweet spot between a pedal-assist e-bike and a full electric moto: light enough to be playful, powerful enough to be serious.

Unlike pure off-road models, the X21 Max ships with integrated road-ready lighting and safety components, making it a street-legal electric dirt bike in many areas — so you can ride from your driveway to the dirt without swapping bikes. Full suspension, hydraulic disc brakes, and rugged off-road tires round out a build that's earned its reputation as a genuine Sur-Ron alternative at a fraction of the price.
