The Surron Ultra Bee electric motorcycle series (note: official models referenced as “Ultra Bee” across technical specifications, with no current “Ultra Vee” designation in production) represents high-performance off-road vehicles engineered for technical terrain. Key characteristics include a robust 21kW peak power output from liquid-cooled PMS motors, achieving 150Nm torque for 0-60km/h acceleration in 3 seconds. The motorcycle features 2060×880×1178mm dimensions with carbon fiber-reinforced frames supporting 120-150kg payload capacity. Advanced specifications include regenerative braking, IP67 waterproofing for all electronics, and 95km/h maximum speed through 74V55Ah Li-ion batteries with 100km range. Available configurations offer 12.5kW or 21kW power variants with 3C certification for road legality.
What distinguishes Ultra Bee’s power system?
The Ultra Bee motors employ permanent magnet synchronous technology with active liquid cooling, maintaining thermal efficiency below 85°C even during 30°+ incline climbs. Peak 21kW power delivery occurs through a 6-phase controller enabling 800A phase current output.

Surron’s proprietary algorithm dynamically adjusts torque mapping across three riding modes: Eco (8kW limit), Sport (15kW), and Race (full 21kW). For example, Sport mode extends range to 130km while maintaining 75km/h cruising speeds. Pro Tip: Always recalibrate throttle response after switching modes – improper calibration causes jerky acceleration on loose surfaces.

How does the frame design enhance performance?
Ultra Bee utilizes forged aluminum alloy mainframes with carbon fiber subframes, achieving 45kg dry weight without compromising structural integrity. The split-design battery compartment allows tool-less swaps in 90 seconds – crucial for endurance racing scenarios.
Geometrically, the 62.5° head tube angle and 315mm ground clearance enable stable 70cm water fording. During testing at Dubai’s Al Qudra Desert track, this design permitted 1.2m jumps without frame deformation. Pro Tip: Install crash bars for rock gardens – despite the sturdy construction, direct impacts on frame members void warranty coverage.
What safety systems does Ultra Bee implement?
Dual 240mm hydraulic disc brakes with sintered pads provide 2.3m stopping distances from 60km/h. The Integrated Vehicle Control (IVC) system combines ABS with traction control, monitoring wheelspin 1000x/second through hall-effect sensors.
Unique to the 2025 model is emergency brake light activation – deceleration rates exceeding 0.8g trigger rapid 5Hz LED flashing to alert trailing riders. For night operations, the 8000-lumen adaptive LED array automatically adjusts beam patterns based on lean angle and speed.
