Dualtron Ultra 2 Upgrade 2025 | 72V 40Ah | 6640W Dual Motor
The Dualtron Ultra 2 Upgrade 2025 marks a new era in high-performance electric mobility. Built around a 72V powertrain and dual 6640W motors, it delivers explosive acceleration, refined control, and long-distance capability. Powered by an LG-M50LT-21700 40Ah battery, it achieves up to 120 km of range and a top speed of 95 km/h, positioning it among the most capable off-road scooters ever built by Minimotors.
Power and Range
At its core lies a 2.9 kWh battery that maintains steady discharge under extreme load, ensuring continuous torque output across the entire ride. The dual motor configuration pushes 6640W peak power, conquering steep inclines and maintaining high speeds with minimal loss in performance. Riders can expect up to 120 km of real-world range on moderate terrain or around 75 mi at mixed throttle, depending on load and riding conditions.
Frame and Build
Constructed from aircraft-grade aluminum alloy, the Ultra 2 Upgrade’s 45 kg frame offers unmatched rigidity and durability. The reinforced neck and stem use a dual-clamp folding system that eliminates flex, enhancing precision at speed. Despite its solid build, it remains manageable for transport, folding compactly for easier storage or vehicle loading.
Suspension and Ride Comfort
Minimotors integrates an elastomer torsion suspension system that adapts to rider weight and terrain. This setup absorbs sharp impacts without losing responsiveness, delivering a smooth and controlled ride across dirt, gravel, or asphalt. The front elastomer module improves steering feedback and stability, while the rear torsion system reduces fatigue on longer rides.
Braking and Safety
Equipped with Nutt hydraulic brakes, finned calipers, and ventilated rotors, the scooter ensures powerful braking even under sustained use. Electronic ABS and regenerative braking work in tandem to provide balanced deceleration and extended brake pad life. The system maintains control during abrupt stops, even on steep descents.
Lighting and Visibility
The lighting system features triple front LEDs two white beams and a central amber signal paired with RGB side strips and a deck-mounted rear light for full 360° visibility. The new DC-DC converter consolidates all lighting controls into a single system, simplifying brightness and mode adjustments. Reflective side panels further improve visibility in low-light conditions.
Control and Display
The EY4 smart display brings next-generation connectivity with real-time performance data, temperature readings, and diagnostics. Bluetooth pairing allows integration with the Minimotors app for detailed tuning of throttle sensitivity, regenerative braking, and lighting preferences. A built-in PIN code adds anti-theft protection, while waterproof sealing ensures reliability in rain or dust.
Design Enhancements
The handlebar has been widened for better leverage, while new cable routing reduces strain during steering. A modular deck layout allows quick access to internal wiring for maintenance. The 11-inch off-road tires with split rims simplify tire replacement and improve durability during high-impact use. Ground clearance remains high, giving the scooter strong off-road capability and stability on obstacles under 5 cm.
Riding Experience
With its 72V power system, responsive throttle curve, and precise steering geometry, the Ultra 2 Upgrade offers a refined yet aggressive feel. The silicone-coated deck provides reliable grip even in wet conditions, while the ergonomically curved handlebars reduce wrist fatigue during extended rides. Combined with its 100 kg load capacity, it’s built for both daily commuting and extreme terrain exploration.
Maintenance and Practical Use
The split rim design minimizes service downtime, and the improved kickstand adapted from the Storm LTD offers better stability on uneven surfaces. Dual charging ports allow faster recharging with two chargers, cutting downtime to under 9 hours. IPX5 sealing protects electronics from rain and dust, extending operational life and reliability.
Conclusion
The Dualtron Ultra 2 Upgrade 2025 72V 40Ah represents the pinnacle of electric scooter engineering: 6640W dual motors, 120 km range, 95 km/h top speed, and rugged off-road performance. With an LG-M50LT-21700 battery, EY4 smart control system, advanced suspension, and precision braking, it is a full-scale evolution of the Ultra legacy built for riders who demand endurance, strength, and unrestrained power in one premium machine.
