The Surron Ultra Bee delivers groundbreaking electric performance across its models, with power outputs ranging from 12.5KW to 21KW and peak torque up to 150Nm. Its 2025 performance variant features a 2000W permanent magnet motor achieving 0–60 km/h in 3 seconds, while higher-spec models use 21KW motors for extreme acceleration (95 km/h top speed). Advanced suspension, dual disc brakes, and regenerative energy systems ensure dominance in urban and off-road environments.
How Does The 2025 Surron Light Bee X Perform?
What defines the Ultra Bee’s motor performance?
Surron’s Ultra Bee uses high-efficiency PMS motors (permanent magnet synchronous) achieving up to 93% energy conversion. The 21KW model produces sustained 28hp output, with thermal management systems preventing power drop during extended climbs. Pro Tip: Use Sport Mode sparingly in desert conditions—motor temperatures can spike 15% faster than in wooded terrain.

Torque delivery varies by model: the 12.5KW base version provides 75Nm, while performance editions hit 150Nm for instant hill starts. For context, this equals the torque of a 250cc gasoline dirt bike but with silent operation. Battery voltage plays a key role here—74V systems enable faster current discharge through MOSFET controllers. Practically speaking, riders can conquer 40° inclines without gear shifts.
How does the Ultra Bee compare to traditional dirt bikes?
Unlike 450cc gas bikes requiring frequent maintenance, the Ultra Bee’s electric drivetrain operates with 70% fewer moving parts. Acceleration parity is striking: 0–50 km/h in 2.8 seconds vs. 3.1 seconds for a Honda CRF450R. However, gas bikes still lead in top-end speed (135 km/h vs. 95 km/h).
| Metric | Surron Ultra Bee (21KW) | KTM 250 XC-F |
|---|---|---|
| Peak Torque | 150Nm | 98Nm |
| Service Interval | 500 hours | 15 hours |
| Noise Level | 62 dB | 102 dB |
The Ultra Bee’s 89kg weight offers agility impossible in 110kg gas counterparts. Energy recovery systems add 8–12km range per descent—crucial for technical trails. But what happens when traction falters? The Ultra Bee’s torque vectoring prevents wheelspin better than mechanical LSDs in gas bikes.
What battery technology powers the Ultra Bee?
Surron employs 74V lithium-ion packs (55Ah–63Ah) with NMC811 cells, yielding 4.1kWh–4.6kWh capacity. The modular design allows 30-minute swaps using Surron Dubai’s quick-release system. Charging at 10A achieves 80% in 1.5 hours, though sustained 15A fast-charging reduces cell lifespan by 30%.
| Model | Voltage | Range |
|---|---|---|
| Ultra Bee Base | 74V55Ah | 85km |
| Ultra Bee X | 74V63Ah | 105km |
Battery management systems (BMS) monitor 16 temperature sensors and cell balance—critical during UAE summers where ambient 45°C demands liquid-cooled packs. Pro Tip: Store batteries at 40–60% charge during off-season to prevent dendrite growth.
