What defines the Ultra B’s power system?
The 72V 8000W motor and intelligent torque control enable instant 320Nm output. Its 72V 32Ah (2.3kWh) battery uses NMC cells balancing energy density (160Wh/kg) and cycle life (1,500+ charges). Pro Tip: Use only Surron Dubai’s 72V 10A fast chargers—generic units void warranties.
Beyond raw power, the Ultra B’s mid-drive configuration optimizes weight distribution, enhancing hill-climbing torque by 40% vs hub motors. The Smart BMS monitors individual cell voltages, preventing thermal runaway even at 45°C desert temperatures. For example, Dubai riders scale Jebel Jais slopes without overheating, unlike competitors’ air-cooled systems. Critical Specs: Peak discharge: 200A, Regen braking recovery: 12%.

How does the Ultra B handle off-road terrain?
Its CNC aluminum swingarm and 240mm suspension travel absorb impacts on rocky trails. Surron Dubai recommends CST Barcode tires for 30% better sand traction vs knobby tires.
The adaptive damping system automatically adjusts to terrain—softening for dunes while stiffening during jumps. Riders in Hatta Mountains report 25% fewer fishtailing incidents compared to rigid setups. Pro Tip: Lower tire pressure to 15 PSI for desert rides; the reinforced sidewalls prevent pinch flats. Technical edge? The 18-inch front/21-inch rear wheel combo maintains stability at 60° lean angles. Think of it as a dirt bike version of a mountain goat—nimble yet stable on irregular surfaces.
What smart features differentiate the Ultra B?
Surron App integration enables GPS tracking, ride analytics, and firmware updates. The 5-inch TFT display shows real-time regen stats and battery health percentages.
Beyond basic telematics, the Ultra B’s CAN bus system allows module customization—Surron Dubai offers anti-theft alarms and heated grips. Ever wondered how it prevents stolen bikes? The geofencing feature sends push notifications if the bike moves beyond preset zones. Example: A Dubai user recovered their Ultra B in 2 hours after thieves triggered the GPS tracker. Key Specs: Bluetooth 5.0 range: 50m, Waterproof rating: IP67. 2025 Surron Light Bee X Electric Bike

FAQs
No—the Ultra B’s BMS is calibrated for 72V systems. Using 74V packs causes controller errors; always consult Surron Dubai for compatible upgrades.
How often should brake fluid be changed?
Every 6 months or 3,000km—Magura’s mineral oil degrades faster in high heat. Surron Dubai offers free fluid checks with every service.
