Sur-Ron Storm Bee Enduro 2026

The Sur-Ron Storm Bee Enduro is a full-size, competition-ready electric motorcycle built to challenge traditional 250cc and 450cc four-stroke enduro bikes head-on. Powered by a liquid-cooled 104V/55Ah battery pack and a high-torque brushless permanent magnet mid-drive motor producing 22.5kW (30 horsepower) of peak output and an astounding 520 Nm of maximum wheel torque, the Storm Bee delivers blistering acceleration without clutch work or gear shifting.

Built on a full-size high-strength aluminum alloy perimeter frame, the Storm Bee features 290mm of fully adjustable inverted front fork travel and 290mm of rear wheel travel via a high-performance piggyback coil shock. Braking is handled by motorcycle-grade multi-piston hydraulic calipers clamping oversized 260mm front and 240mm rear floating steel discs. The 21-inch front and 18-inch rear spoked wheels come factory-fitted with full-size off-road knobby tires.

Advanced electronics include an onboard traction control system (ASR), multi-level regenerative braking, four selectable riding modes (Eco, Rain, Sport, Turbo), and an active reverse drive. The Storm Bee proves that electric off-road motorcycles can deliver full-size motocross capability without noise, exhaust fumes, air filter maintenance, or engine oil changes.

Chassis Engineering & Thermal Management: The Storm Bee features an integrated liquid-cooling circuit for the motor controller and motor housing, maintaining peak electrical efficiency during continuous hard hill climbs and high-speed motos. The high-capacity 104V lithium battery features an intelligent Battery Management System that balances individual cell groups and monitors thermal levels in real time across heavy discharge cycles.

Rider Dynamics & Handling on the Track: The instant 520 Nm of rear-wheel torque provides immediate acceleration off the starting gate, effortlessly lofting the front wheel over rock steps and logs without needing to slip a mechanical clutch. With zero stalling risk at low speeds, technical hill climbs become remarkably controllable, giving the rider total authority through rock gardens and steep ravines.

Maintenance, Safety & Storage Advice: Inspect fork seals and bleed air from the fork caps after every intense ride. Charge the 104V battery using the dedicated OEM high-voltage charging station. For long-term seasonal storage, maintain pack voltage around 50% state of charge in a dry, temperate space. Professional setup of suspension clickers matched to your weight is strongly recommended. Regularly inspect the heavy-duty drive chain tension and torque the rear axle to 60 Nm before entering competition events.

Frequently Asked Questions:

Q: What size are the wheels and tires on the Storm Bee Enduro? A: The Storm Bee comes with full-size motorcycle wheels: a 21-inch front wheel (80/100-21) and an 18-inch rear wheel (100/90-18), compatible with all standard motocross and enduro tires.

Q: How is the motor cooled on the Storm Bee? A: The Storm Bee utilizes an advanced liquid-cooling system with an integrated radiator and coolant pump to circulate fluid through the motor and controller jackets.

Q: Does the Storm Bee require motorcycle licensing? A: The Enduro model is intended for off-road closed-course and trail use. Check local motor vehicle regulations if attempting street registration.

Q: What is the seat height of the Storm Bee Enduro? A: The seat height is 37 inches (940mm), providing full-size motorcycle ground clearance of 310mm.

Q: What braking system is installed on the Storm Bee? A: It features dual-piston hydraulic calipers clamping 260mm front and 240mm rear heavy-duty steel discs with motorcycle-grade sintered pads.

Enduro Geometry & Weight Distribution: The Storm Bee positions its heavy 104V battery pack centrally within the forged aluminum perimeter frame, keeping the center of gravity low and between the footpegs. This mass centralization allows the 127 kg machine to change lines quickly in technical singletrack and track berms while maintaining high-speed stability over desert whoops.

Chassis Rigidity & Competition Geometry: The extruded and forged aluminum frame incorporates thick gusseting around the head tube and swingarm pivot, delivering the torsional stiffness needed to track straight through high-speed whoops. Multi-stage rebound and high-speed compression damping allow riders to tailor chassis response to track conditions.
