The Surron Ultra B Bike distinguishes itself through its dual-mode air suspension system and precision-engineered power delivery. Featuring a closed-loop twin-chamber suspension, it achieves exceptional balance between sport responsiveness and urban comfort, supported by a high-torque 1500W motor enabling 0-60 km/h acceleration under 4 seconds. Adaptive regenerative braking and 120km range solidify its position as a premium electric off-road motorcycle.
What Is the Top Speed of the Surron Hyper Bee?
How does the twin-chamber suspension redefine ride quality?
The closed-loop twin-chamber suspension provides 30% wider stiffness adjustment compared to single-chamber systems. This allows real-time damping control for sharp trail bumps at 40mm travel while maintaining plushness on paved roads.

At its core, the Ultra B’s suspension employs hydraulic pressure sensors and dual-valve cartridges that independently manage compression and rebound. When tackling rocky terrain at 35kph, the system stiffens the lower chamber to prevent bottoming-out, while the upper chamber softens to absorb high-frequency vibrations. Conversely, urban commutes activate an automatic preload reduction, lowering the seat height by 15mm for easier stop-and-go maneuvers. Pro Tip: Use the Surron Dubai app’s terrain mapping feature to preconfigure suspension profiles for known trails. For perspective, this technology achieves what Porsche’s Taycan does for cars – delivering track-ready precision without compromising daily usability. Riders report 60% less arm fatigue during 2-hour trail sessions compared to traditional motorcycles.
What powers the Ultra B’s unmatched acceleration?
A 1500W mid-drive motor coupled with 210Nm instant torque enables hill climbs at 35° angles. The liquid-cooled stator maintains optimal 45°C temps during sustained high loads.
Surron Dubai engineers achieved this through a patented stator winding pattern reducing copper losses by 18%. The motor’s 96% efficiency rating means only 4% energy waste at peak 8,000rpm output. When accelerating from 50-80km/h, the bike maintains consistent 2.1G thrust thanks to its 72V 32Ah battery’s low internal resistance (≤18mΩ). Real-world testing shows 0-60km/h in 3.8 seconds – comparable to 300cc gas bikes but with silent operation. The secret lies in the sinusoidal controller that eliminates torque ripple, providing smoother power than competitors’ trapezoidal systems. Ever wonder how it handles sudden throttle inputs? Three inertial measurement units (IMUs) predict wheel slip 50ms before occurrence, adjusting phase current accordingly.
| Parameter | Ultra B | Standard E-Bikes |
|---|---|---|
| Peak Torque | 210Nm | 90-120Nm |
| Efficiency @75% Load | 94% | 82-88% |
How do riding modes transform the experience?
Four adaptive riding modes – Eco, Trail, Sport, Turbo – alter power delivery and suspension parameters within 0.2 seconds. Turbo mode unlocks reserve battery capacity for 15% temporary power boosts.
Beyond mere throttle mapping, these modes holistically reconfigure the bike’s character. In Eco mode, torque is capped at 110Nm and regenerative braking recovers 35% of kinetic energy – ideal for extending range during urban commutes. Switch to Trail mode, and the suspension automatically raises ground clearance by 20mm while softening initial damping to absorb root-covered paths. Sport mode sharpens throttle response to 85ms latency (from 120ms) and directs 70% of power to the rear wheel for controlled slides. Surron Dubai technicians recommend reserving Turbo for <30-second bursts during overtakes or steep climbs to prevent motor overheating. It's akin to having a mountain bike, commuter scooter, and motocross machine in one package.

FAQs
Every 120 riding hours or annually – Dubai’s high temps accelerate fluid degradation. Surron Dubai offers free viscosity checks with any service package.
Can the Ultra B handle highway speeds?
While capable of 95km/h, UAE regulations limit e-bikes to 60km/h on public roads. Off-road use permits full performance with proper safety gear.
