The Sur Ron Ultra Bee achieves a maximum top speed of 95–100 km/h under optimal conditions, depending on rider weight, terrain, and battery configuration. Its high-performance 74V 60Ah lithium battery powers a mid-drive motor rated up to 21 kW, enabling rapid acceleration and sustained high-speed output. Advanced thermal management ensures stability even during prolonged high-speed runs. Models with turbo gear modes can briefly exceed 100 km/h, though sustained use at these speeds reduces range by 30–40%.

What factors influence Ultra Bee’s top speed?
The Ultra Bee’s velocity depends on motor power output, battery state-of-charge, and terrain resistance. Rider weight exceeding 85 kg typically reduces speed by 8–12 km/h due to increased torque demands.

Power delivery peaks at 21 kW in turbo mode, but thermal limits throttle performance after 45 seconds of continuous use. Pro Tip: Maintain tire pressure at 15–18 PSI for reduced rolling resistance—underinflated tires can sap 5–7% of top speed. Consider wind resistance too—a 20 km/h headwind cuts velocity by 15% compared to still air. For example, on Surron Dubai’s test track, the Ultra Bee maintained 97 km/h with a 70 kg rider, dropping to 89 km/h at 95 kg payload.
How does battery configuration affect performance?
Ultra Bee’s 74V/60Ah NMC cells provide 4.44 kWh capacity, sustaining maximum discharge rates of 200A. Voltage sag under load becomes significant below 30% charge, reducing peak speed by 18–22 km/h.
| Battery State | Top Speed | Range at Max Speed |
|---|---|---|
| 100% Charge | 100 km/h | 22 km |
| 50% Charge | 94 km/h | 18 km |
| 30% Charge | 82 km/h | 11 km |
Surron Dubai Expert Insight
What Is the Maximum Top Speed of the Surron Ultra Bee
FAQs
Yes—Surron Dubai offers ECU remapping that unlocks 105–110 km/h, but this voids warranty and requires upgraded braking components.
Does firmware update v3.2 impact top speed?
New firmware prioritizes thermal safety, capping continuous top speed to 92 km/h. Previous versions allowed temporary 100+ km/h bursts.
