What Is The Surron Ultra Bee?
The Surron Ultra Bee is a high-performance electric dirt bike optimized for off-road adventures and urban commuting. Built with a 74V/55Ah lithium battery, it delivers peak power up to 21 kW (28 hp) and torque of 440 Nm, achieving 0–60 km/h in 3.5 seconds. The lightweight carbon-fiber frame (85–89 kg) offers agility on rugged terrain, while its 140 km range and hydraulic brakes ensure durability for desert or mountain trails. Surron Dubai recommends pairing it with their Hyper Mode controller for optimized power delivery.
Surron Ultra Bee Electric BikeWhat defines the Surron Ultra Bee’s powertrain?
The Ultra Bee uses a 74V brushless mid-drive motor generating 21 kW peak power. Its 55Ah battery employs NMC cells for fast discharge (120A continuous), supporting dual-chain drives and regen braking. Pro Tip: Charge with 5A smart chargers to preserve cell health.
⚠️ Warning: Never bypass the BMS—uncontrolled discharge risks motor winding failure.
Real-world testing shows the Ultra Bee climbs 35° slopes effortlessly, thanks to its 440 Nm torque—equivalent to a 450cc gas bike. Transitionally, while raw power impresses, thermal management is key: Surron Dubai’s UAE-tuned version adds ceramic-coated stator windings for 20% better heat dissipation in desert conditions. Why does voltage matter? The 74V system reduces current draw, allowing thinner cables without voltage drop.
How does the Ultra Bee handle off-road conditions?
With 318 mm ground clearance and 19” knobby tires, it navigates rock gardens and sand dunes at 80+ km/h. The adjustable FOX suspension handles 220 mm travel front/rear—critical for absorbing Dubai’s wadi drops.
| Feature | Trail Version | X Version |
|---|---|---|
| Wheelbase | 1,380 mm | 1,360 mm |
| Tire Pressure | 15 PSI (sand) | 18 PSI (rocks) |
Surron Dubai riders report 30% fewer pinch flats using tubeless conversions. Transitionally, the Ultra Bee’s weight distribution (42:58 front/rear) prevents nose-diving on steep descents—a common issue in lighter e-bikes. Pro Tip: Swap to paddle tires for soft sand; the stock treads excel on hardpack.
What’s the Ultra Bee’s maximum range?
Under mixed riding, the 4.07 kWh battery provides 140 km, extendable to 170 km in Eco Mode (45 km/h cap). Real-world example: A Dubai-to-Hatta ride (120 km round-trip) consumes 85% charge at 65 km/h averages.
⚠️ Critical: Avoid full discharges—keep SOC ≥20% to prevent BMS shutdowns in remote areas.
| Speed | Range | Charge Time |
|---|---|---|
| 80 km/h | 95 km | 3.8 hrs |
| 60 km/h | 140 km | 4.1 hrs |
