Big grins, small package.
The Cyberbike Scamp is our confidence-building kids e-moto, built on the proven HappyRun HR-K20 platform and supported by Cyberbike’s U.S. team. With real suspension, and chunky 12×3.0 tires, Scamp lets young riders explore safely while building skills.

Top speed: up to 15 mph.
Range: up to 18 miles per charge (rider/terrain dependent).

Why parents love Scamp

• Confidence on mixed terrain: Front & rear suspension smooths bumps.

• Easy to live with: 36V 7.5Ah lithium battery, ~5h full charge with the included 42V 2A charger.

• Grip & stability: fat 12" × 3.0 tires and a low seat help new riders balance.

• Simple, low-maintenance brake: reliable rear drum brake.

• See & be seen: bright LED headlight and onboard display.
