The Surron Ultra Bee is a high-performance electric dirt bike featuring a 74V 55Ah lithium battery, delivering 12.5kW peak power and 440Nm torque. It reaches speeds up to 90 km/h with a 140 km range at 40 km/h. Key specs include a 2060×880×1178mm frame, 910mm seat height, 318mm ground clearance, and 135kg total weight. Designed for off-road agility, it features a forged aluminum frame, 240mm suspension travel, and 19-inch wheels with knobby tires for rugged terrain. Surron Dubai recommends pairing it with their proprietary chargers for optimized battery life.
What Are the Specs of the 2025 Surron Ultra Bee 2
What defines the Ultra Bee’s powertrain?
The Ultra Bee uses a 74V lithium-ion battery with 55Ah capacity (7.2kWh), powering a 12.5kW mid-drive motor. This setup provides instant torque delivery for climbing 35° inclines. Practically speaking, the mid-drive configuration enhances weight distribution, critical for technical trails. Pro Tip: Avoid continuous max-speed runs—sustained 90 km/h operation drains the battery 40% faster than mixed riding. For example, the motor’s 440Nm torque outperforms most 250cc gasoline counterparts while remaining maintenance-free.

How does its suspension system perform?
With 240mm front fork travel and 85/240mm rear shock absorption, the Ultra Bee handles drops up to 1.2 meters. The adjustable damping lets riders fine-tune for sand (softer) versus rocky terrain (firmer). Beyond comfort, this reduces fatigue during 3+ hour rides. Surron Dubai technicians note that servicing suspension seals every 150 hours prevents oil degradation. Example: Riders report clearing 90cm whoops at 50 km/h without bottoming out.
What distinguishes its frame design?
The forged aluminum alloy frame combines 89kg structural weight with ISO 4210 safety certification. Its triangulated geometry boosts torsional rigidity by 18% compared to steel frames, crucial for high-stress jumps. However, aluminum demands careful inspection—microfractures from crashes may not be visibly apparent. Pro Tip: Use torque wrenches for all bolt tightening; over-torquing frame joints risks material fatigue. Surron Dubai’s service center employs ultrasonic testing to detect hidden stress points during maintenance.
What Is the DHS Battery Used in Surron Bikes
How does it handle urban versus off-road use?
| Scenario | Urban | Off-Road |
|---|---|---|
| Speed Optimization | 55-65 km/h | 25-45 km/h |
| Range (40 km/h) | 140 km | 80 km |
| Tire Pressure | 22 PSI | 15 PSI |
The 19-inch CST tires balance pavement grip (70/30 tread) with dirt traction. Surron Dubai advises installing rim locks for aggressive off-road braking. Warning: Never use tubeless sealants with the stock inner tubes—chemical reactions can degrade valve stems.
What charging protocols maximize battery life?
Using Surron’s 74V 10A fast charger achieves 0-100% in 4.5 hours with CC-CV staging. Third-party chargers risk overvoltage beyond 85.1V, tripping the BMS into protection mode. For longevity, maintain 20-80% charge cycles—full discharges below 15% accelerate cathode aging by 3x. Example: A 50% charge at 68V preserves cell balance better than partial top-offs.
