Dualtron Achilleus (EY4) Electric Scooter

The Dualtron Achilleus (EY4) is a premium performance electric scooter engineered as a cost-effective, high-tier alternative to the iconic Dualtron Thunder platform. Built around a robust, battle-tested chassis geometry similar to the Thunder's frame, the Achilleus provides demanding riders with uncompromising structural rigidity, dual-motor acceleration, and extended riding endurance at an accessible price point.

Propulsion is delivered by twin brushless DC (BLDC) hub motors generating 1400W nominal power each, resulting in a sustained system output of 2800W. The electrical system is powered by a high-capacity 60V 35Ah battery pack built with genuine LG or Samsung cells (yielding 2100 Wh of energy), granting a manufacturer-declared operating range of up to 120 km on a single charge. Its high-torque powertrain climbs road gradients of up to approximately 58% (30°).

This iteration of the Achilleus comes factory-fitted with the large-format, IPX7 water-resistant EY4 cockpit display featuring native Bluetooth integration for the Dualtron mobile app on iOS and Android. Chassis dynamics are supported by ultra-wide 11-inch tubeless pneumatic tires, front and rear NUTT hydraulic disc brakes with EBS electronic assist, and a modular rubber cartridge suspension system offering 5 interchangeable cartridge hardness ratings.

✅ Key Features

• Dual 2800W Nominal Powertrain: twin 1400W nominal hub motors (2800W continuous rated total) capable of conquering steep road slopes up to approx. 58% (30°).
• 60V 35Ah LG / Samsung Battery: premium 2100 Wh energy reserve delivering a declared range of up to 120 km on a single charge.
• 11-Inch Ultra-Wide Tubeless Tires: wide-profile tubeless tires delivering cornering grip, rolling stability, and reduced puncture vulnerability.
• NUTT Hydraulic Braking System: front and rear hydraulic calipers clamping steel discs paired with an adjustable Electronic Braking Assistance system (EBS).
• IPX7 Water-Resistant EY4 Display: large-screen central dashboard with Bluetooth telemetry compatible with the Dualtron App (iOS / Android).
• Customizable Cartridge Suspension: front and rear elastomeric swingarms with 5 interchangeable rubber cartridge dampening options.
• Dual Fast-Charge Architecture: dual charging input ports reducing total charge time to approximately 3.5 hours using two 5A fast chargers.
• Thunder-Inspired Ergonomics: high 210 mm ground clearance, 980 mm wheelbase, structural rear footrest spoiler, and reinforced kickstand.

Drivetrain and Performance

The propulsion system features dual brushless direct-current (BLDC) motors integrated directly into the wheel hubs. Delivering 1400W nominal power each (2800W continuous rated total), the all-wheel-drive powertrain produces immediate torque across both axles, maintaining steady traction without front-wheel slippage. This continuous output allows the scooter to climb roadway inclines of up to approximately 58% (30°).

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 guidelines, the scooter can reach a top technical speed of up to 80 km/h.

Battery Architecture and Fast Charging

The energy storage system consists of a 60V 35Ah lithium-ion battery pack (2100 Wh) manufactured with authentic LG or Samsung cylindrical cells. The manufacturer specifies an operating range of up to 120 km under standard testing parameters. The pack is governed by an advanced Battery Management System (BMS) that guards against overheating, short-circuiting, over-current, over-discharging, and over-charging.

The scooter incorporates a dual charging port architecture, allowing riders to adapt charging speeds to their schedule:

• Charging with a single standard charger: approximately 20 hours,
• Charging with a single 5A fast charger: approximately 7 hours,
• Fast charging with two 5A fast chargers simultaneously: approximately 3.5 hours.

Braking, Chassis, and Suspension

Stopping control for the 41.7 kg vehicle is managed by front and rear NUTT hydraulic disc brakes. The hydraulic calipers deliver progressive, high-clamping force with light lever pull, reinforced by an Electronic Braking Assistance system (EBS) that applies motor drag to prevent wheel lockup and stabilize deceleration.

The vehicle is equipped with 11-inch ultra-wide tubeless pneumatic tires, providing a wide contact patch for asphalt stability and road holding. Front and rear suspension arms utilize replaceable rubber cartridges (with 5 available hardness compounds), allowing riders to tune dampening stiffness to match their payload and driving style.

Dimensions, Electronics, and Equipment

With a ground clearance of approximately 210 mm and a wheelbase of 980 mm, the Achilleus easily navigates street bumps, potholes, and curbs. In its riding configuration, the scooter measures 1270 x 620 x 1310 mm, supporting rider payloads up to 120 kg.

The folding steering column and folding handlebars collapse the scooter down to 1270 x 280 x 580 mm for storage. The cockpit features the XXL-sized EY4 digital dashboard with an IPX7 waterproof rating and Bluetooth communication for the official Dualtron companion app on iOS and Android. Safety and utility features include an LED headlight, brake light, turn signals, an electric horn, a reinforced kickstand, and a rear deck footrest/spoiler.
