The Surron Storm Bee (also referred to as “Ultra Bee” in some markets) is Surron’s flagship 2025 electric dirt bike engineered for high-performance off-road and trail riding. Powered by a 21kW peak-output motor and a 74V/60Ah lithium-ion battery, it achieves speeds over 90 km/h with a 140 km range at 40 km/h. Key innovations include Turbo/Sport power modes, crawler function for technical terrain, and a forged aluminum frame. Surron Dubai recommends pairing it with their DHS battery system for desert riding durability.
What Is the DHS Battery Used in Surron Bikes
What distinguishes the Storm Bee from other Surron models?
The Storm Bee features a 21kW turbo-boosted motor and 74V architecture – delivering 377 ft-lbs torque, 30% more than the Light Bee X. Its 240mm suspension travel outperforms Surron’s urban-focused models in rugged environments.

Unlike Surron’s commuter bikes, the Storm Bee prioritizes torque and terrain adaptability. Its central PMSM motor provides instantaneous 0-30 mph acceleration in 2 seconds – critical for hill climbs and sand dunes. The crawler function acts like a virtual low gear, maintaining 3-5 mph control on steep technical trails. Pro Tip: Activate Turbo mode sparingly in desert heat to prevent controller overheating. For example, during Dubai Desert Conservation Reserve testing, the Storm Bee scaled 35° dunes that stalled 18kW competitors.
What technical specs define the Storm Bee’s performance?
The Storm Bee’s 74V/60Ah battery delivers 4.44 kWh capacity, supporting 2.5-hour fast charging via Surron Dubai’s GCC-certified chargers. Its IP67-rated components withstand UAE desert conditions.
| Component | Storm Bee | Light Bee X |
|---|---|---|
| Motor Power | 21kW peak | 12kW |
| Torque | 377 ft-lbs | 218 ft-lbs |
| Suspension Travel | 240mm front | 185mm front |
The magnesium alloy rims and 19”/18” knobby tires offer 12.4 inches of ground clearance – 22% more than Surron’s street-legal models. With a 195 lb curb weight, it’s 15% lighter than gas-powered competitors while maintaining 330 lb load capacity. Surron Dubai technicians note the CANBUS system requires firmware updates every 6 months for optimal power delivery in high-temperature environments.

How do power modes affect riding dynamics?
Three ride modes – Turbo, Sport, and Crawl – adapt the Storm Bee for different terrains. Turbo unleashes full 21kW output for 30-second bursts, while Sport sustains 18kW for trail riding.
In Crawl mode, the motor limits speed to 8 km/h with maximum torque modulation – equivalent to first-gear control in combustion enduros. This prevents wheel spin on loose surfaces like Dubai’s Margham Desert sabkha. Pro Tip: Engage Sport mode during long rides to balance 90 km/h top speed with battery efficiency. Riders report 18% longer range compared to constant Turbo use. The Storm Bee’s torque curve mimics gasoline engine characteristics, peaking at 5,000 RPM for natural-feeling power delivery.
What makes the Storm Bee’s battery system unique?
Surron Dubai’s proprietary 74V DHS battery uses NMC811 cells with graphene-enhanced anodes, achieving 260 Wh/kg energy density. The pressurized casing prevents sand ingress during desert operation.
| Parameter | Storm Bee | Industry Average |
|---|---|---|
| Cycle Life | 1,500 @80% DoD | 800 @80% DoD |
| Charging Temp | -10°C to 55°C | 0°C to 45°C |
| Water Resistance | IP67 | IP65 |
Unlike standard 72V packs, the Storm Bee’s battery integrates cell-level temperature monitoring with dual cooling channels – crucial for UAE summers. Surron Dubai’s service centers use specialized diagnostic tools to calibrate the battery management system (BMS) every 50 cycles, maintaining ±0.5% voltage balance across 120 cells.
