The Surron Ultra Bee electric dirt bike is defined by its high-performance specifications across multiple configurations. Key specifications include a 21kW permanent magnet synchronous motor (performance version) or 12.5kW variant, reaching 95km/h top speed with 0-60km/h acceleration in 3 seconds. Structural features include 2060×880×1178mm dimensions, carbon fiber frame weighing 45kg supporting 120-150kg payload. Battery options range from 74V55Ah (4.07kWh) to 72V configurations delivering 100km range. Advanced technical components include dual hydraulic disc brakes, IP67 waterproofing, and smart navigation interfaces. Multiple certifications including 3C compliance ensure road legality across terrains.
What are the Ultra Bee’s powertrain specifications?
The Ultra Bee features 21kW peak motor output in performance editions, generating 150Nm torque through a chain drive system. Lower-tier models deploy 12.5kW motors matching 95km/h speed across all variants via electronically limited RPM control.

Surron’s engineering achieves this through precisely wound permanent magnet rotors achieving 96% energy conversion efficiency. The Performance Edition’s 21kW system requires reinforced MOSFET controllers rated for 400A continuous discharge – that’s enough current to power three mid-sized apartments. Pro Tip: Always use OEM controllers when upgrading motors; aftermarket units often lack proper thermal management for Ultra Bee’s power demands. Consider how sports car engines maintain power through optimal air-fuel ratios – similarly, Ultra Bee’s motor controllers balance voltage sag and heat dissipation during hard acceleration.
| Version | Power | Torque |
|---|---|---|
| Performance | 21kW | 150Nm |
| Standard | 12.5kW | 110Nm |
How does the Ultra Bee’s battery system perform?
Using 74V55Ah lithium-ion packs, the Ultra Bee achieves 100km range under mixed riding conditions. Fast-charging capability replenishes 80% charge in 90 minutes via CCS-compatible ports.
The battery architecture employs automotive-grade NMC cells arranged in 20S4P configuration, delivering 400A peak discharge rates. Smart BMS technology monitors individual cell voltages within ±25mV tolerance, preventing imbalance during rapid charge cycles. Think of it like an orchestra conductor – the BMS ensures all 80 cells (20 series × 4 parallel) perform in perfect harmony. Warning: Never expose batteries to temperatures above 60°C; sustained heat accelerates capacity degradation by up to 30% per 100 cycles.
What chassis features enable Ultra Bee’s off-road capability?
The carbon fiber monocoque frame combines 45kg lightweight construction with 150kg payload capacity. Hydraulic suspension provides 220mm front/240mm rear travel, tackling 35° inclines effortlessly.
Surron’s engineers achieved this through aerospace-grade layering techniques – 12K carbon fiber sheets are vacuum-formed in 7-axis molds creating optimal stress distribution. The inverted front fork uses 46mm stanchions with adjustable rebound damping, comparable to premium motocross bikes. Imagine a gymnast’s balance beam – the Ultra Bee’s wheelbase and weight distribution maintain stability during complex maneuvers. Pro Tip: Clean suspension seals after muddy rides; particulate buildup causes fork tube scoring within 50 hours of abuse.

FAQs
Yes, 12.5kW variants include 3C certification allowing registration with full lighting kits and VIN compliance.
What’s the battery replacement cost?
Expect AED 5,200 for OEM 74V55Ah packs – third-party batteries void Surron’s 2-year warranty.
How does heat affect performance?
Motor output reduces 15% above 45°C ambient; install auxiliary cooling fans for sustained dune riding.
