Dualtron Sonic Model A (ALIEN) Electric Scooter

The Dualtron Sonic Model A, codenamed ALIEN, represents the flagship hyper-scooter of Dualtron's next-generation SONIC lineup. Engineered in Korea as the technological counterpart to a Dualtron Thunder 4, this machine introduces an automotive-grade CAN bus architecture, modular quick-service wheel design, and active thermal management to the ultra-performance electric scooter segment.

Its dual-motor All-Wheel Drive powertrain generates an impressive 5000W nominal output (2 x 2500W) and peaks at an astonishing 11,200W (2 x 5600W max output), allowing riders to scale severe inclines of up to approximately 70% (35°). Electrical reserves are housed in a massive 72V 40Ah battery pack built with high-discharge 9C Samsung 21700 50S or LG INR21700H51T cells, delivering a manufacturer-declared range of up to 125 km on a single charge.

Handling and high-speed stability are backed by a factory-fitted directional steering damper, 11-inch tubeless Runflat tires, and a NUTT 4-piston hydraulic braking system clamping 160 mm discs. Braking performance is unified via a Combined Braking System (CBS) distributing a 50/50 front-to-rear ratio, reinforced by ABS and EBS electronic assistance. The cockpit is controlled by an auto-dimming central display, the multi-function Tenzon switchgear, and a dedicated One-Touch Turbo booster button.

Drivetrain and Performance

The propulsion system of the Sonic Model A (ALIEN) is powered by twin brushless direct-current (BLDC) motors delivering a nominal output of 2 x 2500W (5000W total nominal power). Under maximum load, the system achieves a peak output of 5600W per motor, yielding 11,200W of total maximum peak power. Rider input is processed through the ergonomic Tenzon control module, featuring a dedicated ‘One-Touch Turbo’ trigger for rapid torque spikes when executing overtakes or ascending steep terrain.

The scooter ships with an electronic 25 km/h limit in compliance with EU public road standards. On private land or closed raceways, delimiting the scooter unlocks its unrestricted technical maximum speed of up to 110 km/h. Its substantial torque profile allows climbing slopes of around 70% (35°). Sustained performance is preserved by patented centrifugal air vents inside the motor assemblies that automatically vent warm air at higher wheel rotations without consuming electrical battery power.

Battery Architecture and Fast Charging

Energy is stored in a 72V 40Ah lithium-ion battery pack (2880 Wh capacity) utilizing high-discharge 21700 cylindrical cells (9C discharge rate) from Samsung SDI (50S) or LG Energy Solution (INR21700H51T). The manufacturer specifies a travel range of up to 125 km under optimal testing conditions.

The pack is governed by a CAN bus-linked Smart BMS circuit that actively monitors cell balancing, temperatures, and live currents. The BMS shields the internal cells against short circuits, over-current, over-discharging, over-charging, and thermal spikes. Utilizing the dual charging ports:

• Standard fast charging with a single 5A charger: approximately 8 hours.
• Dual fast charging with two 5A chargers in parallel: approximately 4 hours.

Braking, Suspension, and Chassis Dynamics

Deceleration is governed by a NUTT 4-piston hydraulic braking system utilizing 160 mm discs. The system is engineered with Combined Braking System (CBS) linkage: applying the front brake automatically applies the rear caliper in an equal 50% front / 50% rear distribution, preventing nose-dive instability. This setup is supported by electronic braking assistance (EBS) and an electronic anti-lock braking system (ABS).

The scooter is fitted with 11-inch tubeless Runflat tires that maintain structural integrity during pressure loss. Front and rear suspension arms utilize replaceable elastomer damping gaskets to tune stiffness to rider payload. High-speed handling is reinforced by a pre-installed directional steering damper that suppresses headshake. A modular wheel assembly permits the independent detachment of the tire, rim, or motor for simplified maintenance.

Cockpit, Telemetry, and Equipment

The center of the cockpit is fitted with an intelligent LCD dashboard featuring an integrated ambient light sensor that adjusts screen brightness between direct daylight and night riding. The built-in GPS module provides real-time tracking through the Dualtron App (iOS / Android), which also controls lighting parameters, anti-theft alarms, and digital voltmeter diagnostics.

The lighting suite features sequential flowing turn indicators, an elevated high-lumen headlight, deck LEDs, rear warning/stop lights, and an integrated mechanical speaker horn. Measuring 1340 x 650 x 1360 mm unfolded with a 1023 mm wheelbase and 180 mm ground clearance, the vehicle folds down to 1340 x 290 x 580 mm. Total vehicle curb weight is approximately 53.5 kg, rated for payloads up to 120 kg.
