Sur-Ron Storm Bee Engineering Breakdown & Trail Capability
The 2026 Sur-Ron Storm Bee represents the company's expansion from youth play bikes into the full-size enduro motorcycle category. Built around a massive forged aluminum perimeter chassis, the Storm Bee delivers 250cc-four-stroke-rivalling performance without internal combustion emissions or noise.
High-Voltage 104V Powertrain & 520 Nm Torque
The Storm Bee uses a high-voltage 104V 55Ah ternary lithium battery pack storing 5.72 kWh of energy. The mid-mounted synchronous motor generates 22.5 kW (30 HP) peak power and sends 520 Nm of instantaneous torque through a dual-stage gear and 520-chain reduction drive. Accelerating from 0 to 50 km/h in 1.8 seconds, the Storm Bee lofts the front wheel on demand over trail obstacles.
Forged Aluminum Chassis & 290mm Long-Travel Suspension
A high-strength forged aluminum perimeter frame keeps total curb weight at 127 kg (280 lbs). Suspension duties are handled by 47mm inverted front telescopic forks and a linkage-assisted rear monoshock, both offering 290 mm of wheel travel. Combined with 310 mm (12.2 inches) of ground clearance and full-size 21-inch front and 18-inch rear spoked wheels, the Storm Bee glides across logs, roots, and deep whoops.
SRTC Traction Control & Electric Reverse Assist
Technical woods riding is supported by Sur-Ron's proprietary SRTC system, which monitors rear wheel slip and regulates motor output to maintain forward traction on slick mud and loose shale. Furthermore, an electric reverse gear button on the left switchgear enables riders to back out of tight crevices and steep hill stalls with minimal physical exertion.
