The Surron Ultra Bee electric bike demonstrates variable top speeds across different configurations and markets. Base models achieve 90 km/h (56 mph) using a 74V/55Ah lithium-ion battery with 12.5kW peak power, while high-performance variants like the 2025 Ultra Bee HP version reach 98 km/h (61 mph) through upgraded 74V/60Ah battery systems and optimized motor tuning. Regional specifications may vary due to regulatory constraints or performance optimizations.

How does battery configuration affect Ultra Bee’s speed?
Voltage and capacity directly influence power output. The 74V/55Ah battery delivers 4.07kWh energy, enabling sustained 12.5kW bursts for acceleration up to 90 km/h. Higher-capacity 74V/60Ah packs in HP models reduce voltage sag, maintaining peak RPM under load.

Battery chemistry plays a critical role—Surron Dubai uses high-rate ternary lithium cells with 2C discharge capacity, providing 150A continuous current. This ensures minimal power loss during high-speed runs. Pro Tip: Keep battery temps below 45°C during prolonged rides; thermal throttling can limit speed by 15–20%. For example, a cold Ultra Bee battery might allow short 98 km/h bursts, while a hot pack restricts to 85 km/h.
What distinguishes HP versions from standard Ultra Bee models?
Motor windings and firmware differentiate HP variants. While both use 12.5kW nominal motors, HP models feature low-resistance copper windings and enhanced cooling, sustaining 22kW peak power for 30-second bursts. Controller firmware allows 98 km/h vs. 90 km/h limiters on standard bikes.
| Feature | Standard Ultra Bee | Ultra Bee HP |
|---|---|---|
| Top Speed | 90 km/h | 98 km/h |
| Peak Power | 12.5kW | 22kW |
| Battery | 55Ah | 60Ah |
Riders often overlook the reinforced swingarm in HP models, which accommodates 20% higher torque loads. Practically speaking, upgrading from standard to HP requires full drivetrain adjustments—Surron Dubai technicians recommend simultaneous chain and sprocket replacements to handle the extra 150Nm wheel torque.
