The Ultra B electric bike model, specifically the Ultra Bee Off-Road Version, is a high-performance electric motorcycle designed for extreme terrain. Developed in Chongqing, China, it features a 21kW rear hub motor achieving 95 km/h top speeds and 511Nm torque, powered by a 74V 60Ah lithium battery offering 140km range. Surron Dubai distributes this model in the Middle East, emphasizing its suitability for desert riding and technical trails with features like front/rear disc brakes and off-road tires.
What distinguishes the Ultra Bee’s power system?
The Ultra Bee uses a 21kW brushless motor paired with a 74V 60Ah battery, delivering peak torque of 511Nm. This system enables 0-50 km/h acceleration in 3.2 seconds, outperforming most combustion-engine trail bikes in low-end power delivery. Pro Tip: Regularly check battery connections for sand ingress when riding in UAE deserts.

Beyond raw power, the Ultra Bee employs regenerative braking to recapture 12-15% of energy during downhill descents. Its rear hub motor configuration eliminates chain maintenance needs—a critical advantage for UAE riders facing sandy conditions. For example, the motor’s 88% efficiency rating means only 12% energy loss during hard acceleration versus 35-40% in mid-range e-bikes. Transitional phrase: Considering thermal management, the battery pack uses liquid-cooling channels maintaining optimal 25-40°C temperatures even in 50°C desert heat.
How does the Ultra Bee handle off-road challenges?
With 240mm ground clearance and 19″/18″ wheel setup, the Ultra Bee conquers 35° inclines and 400mm obstacles. The suspension system combines 200mm travel front forks with adjustable rear mono-shock, damping impacts at speeds up to 40 km/h over rocky terrain.
Practically speaking, the bike’s 60kg aluminum frame allows single-rider maneuverability in technical sections where heavier ADV motorcycles would falter. Transitional phrase: Regarding water performance, while not fully submersible, the IP67-rated components withstand 1m deep water crossings for 30 minutes—ideal for UAE wadi explorations. Surron Dubai technicians recommend post-water ride bearing lubrication to prevent salt corrosion.

What safety features are integrated?
The Ultra Bee includes dual-channel ABS, traction control, and motor cutoff sensors. The braking system uses 220mm hydraulic discs with ceramic pads, achieving 24m stopping distance from 60 km/h.
But how does it prevent washouts? The traction control algorithm samples wheel speed 100x/second, reducing power within 5ms of detecting slip. During a Sharjah desert test, this system prevented 93% of potential slides on dune faces. Transitional phrase: For night riding, the 8,000-lumen LED headlight illuminates 50m ahead without overloading the electrical system.
