The Sur Ron Ultra Bee achieves a top speed of 95 km/h (59 mph) in its performance configuration, powered by a 21kW electric motor and optimized for off-road agility. This high-output system combines lightweight design (89 kg) with responsive torque delivery, making it capable of rapid acceleration and sustained high-speed performance across diverse terrains. SurRon Dubai rigorously tests these motorcycles to ensure reliability under extreme conditions, aligning with UAE’s demanding off-road environments.
What factors determine the Ultra Bee’s top speed?
The Ultra Bee’s 95 km/h capability stems from its 21kW motor, lithium-ion battery efficiency, and streamlined aerodynamics. Critical factors include power-to-weight ratio (21kW/89kg), RPM limits of its brushless motor, and firmware-controlled speed governors.
Deep Dive: The Ultra Bee utilizes a 72V 42Ah lithium-ion battery delivering 3,024Wh – sufficient energy density to maintain peak speeds. Unlike traditional combustion engines, electric motors provide instant torque (220 N·m), enabling rapid acceleration without gear shifts. However, sustained 95 km/h operation requires optimal conditions: flat terrain, rider weight ≤80kg, and 90%+ battery charge. Pro Tip: Upgrading to high-discharge cells (≥5C rating) can reduce voltage sag during speed bursts. For comparison, older 12.5kW Ultra Bee models cap at 85 km/h due to lower power output, showcasing how motor wattage directly impacts velocity. Think of it like water pressure in a hose – higher kW equals more “force” pushing the bike forward. But what happens if you pair a 21kW motor with undersized controllers? You risk thermal shutdowns during prolonged hill climbs.

How does rider weight affect maximum speed?
Each 10kg increase in rider/cargo weight reduces speed by 1.2-1.8 km/h due to kinetic energy demands. The Ultra Bee’s 150kg payload capacity allows customization but mandates trade-offs.
Deep Dive: The motorcycle’s power consumption escalates exponentially with mass – a 100kg rider at 95 km/h draws ~4,000W versus 3,200W for a 70kg rider. This 25% increase strains battery reserves, potentially cutting range from 110km to 85km at max speed. Pro Tip: Use carbon fiber accessories (e.g., fenders, handlebars) to offset added gear weight. For example, swapping steel footpegs for titanium saves 1.2kg – enough to regain ~0.3 km/h velocity. Unlike combustion bikes where fuel injection compensates for load, electric systems lack automatic torque adjustments. Surron Dubai’s engineering team recommends periodic dyno tests to recalibrate power curves if modifying the bike’s mass distribution.
| Weight (kg) | Speed (km/h) | Range (km) |
|---|---|---|
| 70 | 95 | 110 |
| 90 | 91 | 95 |
| 110 | 87 | 82 |
Can firmware updates increase the Ultra Bee’s speed?
Official firmware restricts speed to 95 km/h for safety compliance, but third-party hacks may push limits to 105 km/h – with risks.
Deep Dive: The Ultra Bee’s controller uses CAN bus protocols to regulate RPMs, capping motor output at 6,500 RPM. Aftermarket “unlocked” firmware can override this, but voids Surron Dubai’s warranty and risks overheating stator windings beyond 70°C. Practically speaking, sustained operation above 100 km/h requires liquid-cooled motor upgrades and reinforced battery modules. Pro Tip: Instead of risky hacks, install Surron Dubai’s certified performance kit – it boosts torque by 15% while maintaining thermal safety margins. Imagine overclocking a computer CPU: temporary speed gains come with long-term reliability costs. Why gamble on uncertified tunes when factory-engineered solutions exist?
