The Surron Ultra Bee is a high-performance electric dirt bike designed for both off-road adventures and urban commuting. As Surron’s flagship model in 2025, it features a 74V/60Ah lithium battery paired with a 21kW peak power PMSM motor, delivering explosive acceleration (0-60km/h in 2.9 seconds) and a 140km range. Its forged aluminum frame, 240mm suspension travel, and smart torque vectoring make it ideal for technical trails while maintaining street-legal compliance in multiple regions. Surron Dubai recommends this model for riders seeking professional-grade electric mobility with advanced telemetry through its 5″ color touchscreen interface.
What Are the Specs of the 2025 Surron Ultra Bee 2
What makes the Ultra Bee’s power system unique?
This 74V architecture combines a permanent magnet synchronous motor with multi-phase torque control. Unlike traditional hub motors, the centrally-mounted 21kW unit achieves 377Nm wheel torque through dual-range gear reduction (12:1 low / 6:1 high), enabling both hill-climbing power and 90km/h top speeds.

The Ultra Bee’s powerband adapts dynamically: in Sport Mode it sustains 18kW continuous, while Turbo Mode unleashes full 21kW bursts for 15-second intervals. Surron Dubai technicians emphasize that the liquid-cooled controller maintains MOSFET temperatures below 85°C even during desert rides. For example, the crawling function reduces speed to 8km/h without stalling – perfect for rock gardens. Pro Tip: Recalibrate torque vectoring every 50 hours of hard enduro use through the vehicle’s diagnostic menu.
How does the suspension handle extreme terrain?
Its KKE inverted forks offer 240mm travel with 32-step compression damping adjustability. The rear shock’s linkage system provides progressive spring rates, managing everything from sand whoops to 1m drops. Compared to the Light Bee X, the Ultra Bee adds a secondary rebound circuit in the rear damper.

Surron Dubai riders report the stock setup works best at 185-210psi for 70kg riders. Beyond basic sag adjustments, the hydraulic bottoming control ring prevents harsh bottom-outs during 3m+ jumps. Practically speaking, this suspension package lets you transition from Dubai dunes to Hajar Mountain trails without tool adjustments.
