How powerful is the Storm Bee?

The Storm Bee's 22.5kW mid-drive motor produces 383.5 ft-lbs (520 Nm) of rear-wheel torque, accelerating 0–50 mph in 3.6 seconds with a top speed of 68.3 mph — full-size electric motocross performance.

Who is the Storm Bee for?

Experienced riders wanting a genuine full-size electric MX/enduro machine. With a 56.2in wheelbase, 37in seat height and 21in/18in wheels, it rides like a proper motocross bike — not an oversized e-bike.

What range and charge time does the Storm Bee offer?

Up to 74.5 miles at 31 mph from the 104V 55Ah removable ternary lithium pack. A 20–80% charge takes around 4 hours.

Does the Storm Bee overheat under hard riding?

The 150V sine-wave controller is liquid-cooled with integrated temperature sensors that actively manage output, so performance stays stable and safe even under sustained heavy load.

What warranty and support do I get?

A 12-month official Sur-Ron warranty on the motor, controller, display, battery, chassis and swingarm, plus lifetime rider support and servicing from our certified Kent workshop.

Performance like you've never known it. The Storm Bee is Sur-Ron's full-size electric enduro flagship: a 22.5kW mid-drive motor with liquid-cooled 150V sine-wave FOC controller punches out 383.5 ft-lbs of rear-wheel torque for 0–50 mph in 3.6 seconds and a 68.3 mph top speed. The 104V 55Ah high-power ternary lithium battery feeds it for up to 74.5 miles, while the motorcycle-grade forged aluminium frame with a 56.2in wheelbase, fully adjustable long-travel suspension (47mm inverted forks) and full-size 21in/18in off-road wheels deliver true motocross capability. SRTC traction control and BERS regen keep all that power usable. This is the new standard in electric motocross. Off-road use only.
