Dualtron Thunder 3 (EY4) Electric Scooter

The Dualtron Thunder 3 represents the apex evolution of Minimotors' legendary hyper-scooter series, continuing the heritage established by the renowned Thunder 1 and Thunder 2. Engineered to handle extreme riding conditions, the Thunder 3 incorporates comprehensive structural and electronic upgrades, introducing certified IPX5 water resistance for the chassis and IPX7 submersion resistance for its central digital cockpit display.

Propulsion is delivered by twin brushless DC (BLDC) hub motors producing 2500W nominal power each (5000W continuous rated total), capable of reaching up to 10,800W max output according to technical specification documentation (or up to 11,000W in maximum burst mode). Electrical reserves are housed in a massive 72V 40Ah battery pack built with genuine LG or Samsung cells (yielding 2880 Wh of capacity), providing a manufacturer-declared range of up to 130 km on a single charge.

High-speed stability is anchored by a factory-installed directional steering damper, sport 4-piston NUTT hydraulic disc brakes with integrated cooling clamping 160 mm rotors, and ultra-wide 11-inch tubeless pneumatic tires. The cockpit is upgraded with the large-format EY4 display with Bluetooth connectivity for the Dualtron mobile app (iOS / Android), an OVERTAKE booster button, twin high-power LED headlights, a wider 700 mm handlebar, and a reinforced triple-security stem folding assembly.

Drivetrain and Performance

The propulsion system features dual brushless direct-current (BLDC) motors integrated directly into the wheel hubs. Delivering 2500W nominal power per wheel (5000W total continuous nominal output), the system provides an approximate 5–10% power increase over the Thunder 2 platform. Under peak demand, the powertrain outputs up to 10,800W (up to 11,000W peak output). Riders can engage the handlebar-mounted "OVERTAKE" button for rapid torque delivery during overtakes or steep climbs.

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 100 km/h.

Battery Architecture and Fast Charging

Energy is stored in a 72V 40Ah lithium-ion battery pack (2880 Wh) composed of authentic LG or Samsung cylindrical cells. The manufacturer specifies an operating range of up to 130 km under favorable testing parameters. A multi-layer Smart BMS circuit continuously protects against short circuits, over-current, overheating, over-discharging, and over-charging.

The scooter incorporates a dual charging port architecture, allowing riders to adapt charging speeds according to charger configurations:

• Charging with a single standard charger: approximately 26–28 hours,
• Charging with a single fast charger: approximately 8 hours,
• Dual fast charging with two fast chargers in parallel: approximately 4 hours.

Braking, Chassis, and Steering Stability

Stopping control for the 51.2 kg chassis is managed by NUTT 4-piston hydraulic disc calipers paired with 160 mm steel rotors featuring integrated cooling architecture. Four pistons apply balanced, multi-point pressure across the brake pads to deliver short stopping distances and thermal endurance, supplemented by an Electronic Braking Assistance system (EBS).

The chassis rides on 11-inch ultra-wide tubeless pneumatic tires mounted to swingarm suspension units with replaceable elastomeric rubber cartridges. High-speed handling is reinforced by a pre-installed directional hydraulic steering damper that stabilizes the steering column against harmonic oscillation.

Water Resistance, Dimensions, and Equipment

The Thunder 3 features certified IPX5 water resistance for the main frame and an IPX7 water-immersion rating for the EY4 digital dashboard, making it safe for riding in rain and wet street conditions. The handlebar is widened to 700 mm to optimize steering leverage and rider comfort.

The chassis provides a ground clearance of approximately 180 mm and a wheelbase of 970 mm. In its unfolded riding configuration, the scooter measures 1208 x 609 x 1267 mm, collapsing down to 1208 x 317 x 577 mm via its reinforced folding mechanism. Curb weight is approximately 51.2 kg, supporting rider payloads up to 120 kg. Standard equipment includes twin front LED headlights, brake lights, turn signals, warning flashers, a loud horn, and a reinforced kickstand.
