Dualtron X Limited (EY4) Electric Scooter

The Dualtron X Limited (EY4) represents the absolute pinnacle of hyper-scooter engineering, hailed throughout the global e-mobility community as the undisputed "Queen of E-Scooters." Built upon an expanded chassis developed from the iconic X2 platform, the X Limited provides unprecedented dimensions, high-speed stability, and long-range grand touring comfort on par with lightweight road motorcycles.

Propulsion is delivered by twin brushless direct-current (BLDC) hub motors producing 2000W continuous nominal power each (4000W nominal total). Utilizing 50A Square Wave controllers capable of peaking at 70A in Boost Mode, the powertrain unleashes an astonishing maximum output of 12,000W (2 x 6000W peak). Electrical reserves are housed in a massive 84V 60Ah battery pack (95.4V max output, 5040 Wh capacity) constructed with premium LG or Samsung 21700 cells, delivering a manufacturer-declared operating range of 170 km to over 200 km on a single charge.

Road absorption is managed by dual adjustable hydraulic spring shock assemblies (950 lbs/in springs) offering 19 distinct damping settings. Standard equipment includes massive 13-inch x 3-inch RCS ultra-wide tubeless tires, a factory directional steering damper, NUTT 4-piston hydraulic disc brakes with ABS and EBS assistance, a 100W/8000-lumen LED projection lighting suite, and the widescreen EY4 central cockpit display paired with the official Dualtron companion app on iOS and Android.

Drivetrain and Performance

The propulsion system features dual brushless direct-current (BLDC) motors integrated directly into the front and rear wheel hubs. Each motor produces a nominal continuous rating of 2000W (4000W combined nominal continuous output). Driven by dual 50A Square Wave motor controllers capable of bursting to 70A in Boost Mode, the system generates an extraordinary 12,000W of total peak output (6000W per motor). This monumental torque allows the 82.9 kg vehicle to conquer uphill roadway grades of up to approximately 70% (35°).

In compliance with European road mobility standards, the vehicle is software-limited to 25 km/h out of the box. When operated on private tracks and delimited according to manufacturer instructions, the scooter achieves an unrestricted top technical speed of up to 110 km/h.

Battery Architecture and Fast Charging

Energy is stored in an 84V 60Ah lithium-ion battery pack (95.4V max output, 5040 Wh capacity) assembled with high-discharge 21700 cells from LG or Samsung. The battery pack is evaluated for a lifespan of up to four years under proper storage and maintenance. Under standard operating conditions, the vehicle achieves up to 170 km of declared range, expanding to 200 km and beyond under moderate cruising speeds.

The battery system is continuously protected by an intelligent Battery Management System (BMS) guarding against overheating, short-circuiting, over-current, over-discharging, and over-charging. Dual charging ports support up to 10A total input. Using the included 5A fast charger, full charging takes approximately 15 hours (or faster when operating two fast chargers in parallel).

Chassis, Wheels, and Braking Dynamics

Road absorption is handled by dual hydraulic coil-over shock absorbers (950 lbs/in spring rating) on both swingarms. With 19 manual damping clicks, riders can calibrate chassis behavior between plush high-frequency bump absorption and firm high-speed touring stability. Road contact is maintained by 13-inch x 3-inch RCS ultra-wide tubeless pneumatic tires that roll smoothly over expansion joints and asphalt fissures.

Stopping power is managed by NUTT 4-piston hydraulic disc brakes on both wheels. The quad-piston design increases pad contact area over the discs, delivering 50% more stopping power than the X2 platform while operating quietly. The mechanical calipers work in tandem with an anti-lock braking system (ABS) and an adjustable magnetic Electronic Braking Assistance system (EBS).

Ergonomics, Dimensions, and Equipment

The expanded chassis provides a ground clearance of approximately 190 mm and a wheelbase of 1100 mm. Unfolded, the vehicle measures 1450 x 648 x 1400 mm, accommodating an optional touring seat for seated long-distance travel. The steering column and handlebars fold down to 1450 x 358 x 775 mm for vehicle transport in large SUV trunks. The reinforced structure supports rider payloads up to 150 kg.

The lighting suite draws over 100W of total electrical power, projecting an estimated 8000 lumens down the road via three 30W headlights and two 5W auxiliary pods with integrated turn signals. Cockpit telemetry is managed by the central EY4 display with Bluetooth pairing for the Dualtron App (iOS / Android). Additional amenities include footrests with light reflectors, a high-decibel motorcycle horn, and a reinforced kickstand.
