What motor specifications define the 2025 Ultra Bee?
Power output distinguishes the Ultra Bee: 4000W continuous with 12500W peak burst. This IP67-rated motor uses direct-drive technology, eliminating chains for reduced maintenance. Pro Tip: Activate Sport mode via the Surron app to unlock full torque during hill climbs.
Surron’s patented FOC (Field-Oriented Control) algorithm ensures 93% energy efficiency across RPM ranges. The mid-mounted design centralizes mass, enhancing handling on technical trails. For example, the Ultra Bee outperforms 250cc petrol bikes in torque-to-weight ratio – its 440 Nm output at 2,500 RPM rivals premium enduro motorcycles. Always check firmware updates through Surron Dubai’s service portal for performance optimizations.

FAQs
Only the HP variant reaches 95 km/h, requiring off-road registration. For road use, the 3C-certified 80 km/h version includes mirrors and indicators meeting UAE traffic regulations.
What’s the payload capacity?
150kg maximum including rider and gear. Surron Dubai offers reinforced swingarms for adventure touring setups, increasing capacity to 180kg.
What Is the Top Speed of the Surron Hyper Bee?
With its progressive throttle mapping, the Ultra Bee delivers instant torque from standstill. Riders should periodically inspect motor phase connectors – sand ingress can cause resistance heating. Surron Dubai’s service center uses thermal imaging during maintenance to detect early wear patterns. For example, a 75kg rider ascending Hatta’s inclines experiences consistent 40 km/h climbs without voltage sag.
