2x2 Ultra Bike - All-Wheel-Drive Electric Motorcycle

The 2x2 Ultra Bike is the world's most capable all-wheel-drive electric motorcycle for extreme off-road terrain, developed by Robo Systems and offered here in a TheArsenale Edition that adds the curator's signature aesthetic layer to this unmatched engineering platform.

The Concept

Robo Systems built the 2x2 Ultra Bike around a single premise: conquer terrain that defeats everything else. Where conventional off-road vehicles rely on traction control and suspension travel, this machine relies on physics. Two independent hub motors, one per wheel, deliver torque exactly where the ground demands it. The balloon tires exert so little pressure per square centimeter that the bike can traverse sand, marsh, deep snow, and even float across shallow water. It is not a toy or a novelty but a precision instrument designed for expedition-level crossings in environments that have no roads.

The Build

Each wheel houses a 1,000-watt brushless DC motor, giving the bike true two-wheel-drive traction without a differential or drivetrain linkage. Power comes from a 1.6 kWh LiFePO4 battery sealed in a watertight enclosure where a conventional fuel tank would sit. A built-in pulse charger with adjustable current up to 15 amps means the battery can be topped up from any standard outlet in around an hour. For longer expeditions, the chassis accepts a portable gasoline generator that charges the battery on the move, effectively removing range as a limiting factor. Two small fuel tanks integrated into the wheel housings feed the generator when needed.

The balloon tires are the defining visual and functional element: high-volume, low-pressure casings that spread load across a wide footprint. They resist punctures under normal off-road use and provide enough buoyancy to allow the bike to float and propel itself across water. The hydraulic brake system on both wheels uses 190mm discs for controlled stopping on loose and uneven terrain. A built-in 3,000-watt inverter lets the bike power tools and electrical equipment directly from its battery, making it a mobile power source as well as a vehicle.

The Ride

The 2x2 Ultra Bike tops out at 50 km/h on firm ground and delivers up to 50 km of range on a single charge under typical mixed-terrain conditions. At 60.7 kg it is light enough to be managed manually when conditions require, and the all-wheel-drive system means momentum is maintained on surfaces that would ground a conventional motorcycle instantly. The machine is engineered for slow, deliberate progress through genuinely hostile environments, not for speed on dirt tracks.
