After springing its electric unicycle (EUC) lineup for full off-roading, electric transport specialist InMotion is upping the ante (and danger) once again. The all-new V13 Challenger debuts as the fastest, most powerful one-wheeler in the world, according to the Chinese company. Capable of putting out a peak of 10,000 watts and powering up to speeds of 87 mph (140 km/h), the V13 is more explosive than many electric two-wheelers. An improved suspension, modular design and updated electronics promise to deliver a ride that's as safe and personalized as it is ferocious.
The new V13 Challenger features a host of new components and design features to help maximize power and speed while keeping the rider safe (ish?). A 126-V electrical architecture with upgraded cables ensures smooth, safe power delivery from the 3,024-Wh battery pack to the 4,500-W motor, which boasts a peak output of 10 kW and maximum torque of 300 Nm.
InMotion estimates that all that power and torque can be focused into a top lift speed of 87 mph (140 km/h) – lift speed, also called free spin speed, is the top speed the V13 will register when simply lifting it straight up off the ground and punching the accelerator. The actual speed it will reach on the ground will depend upon the weight of the rider, ground surface, battery status and other factors, but the fact we're even talking about nearly 90 mph on a unicycle should be highly enthralling, highly terrifying or maybe both, depending upon your e-wheel experience or lack thereof.
Based on one of the first retailer ads for the V13 Challenger, it looks like actual top speed on the ground will fall around 56 mph (90 km/h) — still enthralling and/or terrifying and a sizeable increase over InMotion's current speed king, the 43.5-mph (70-km/h) V12. That same ad lists range at 124 miles (200 km).
Of course, stuffing as many kilowatts as possible into a single-wheeler and letting first-adopters absolutely rip with no other considerations could prove a recipe for disaster and lawsuit, so InMotion does plenty of additional tweaking and upgrading. That starts with a new suspension that delivers 3.5 inches (90 mm) of cushion by way of independent air shocks and dampers on each side of the wheel. We still wouldn't be eager to hit a bump at highway speed, but InMotion promises a smooth, stable ride. The user can adjust pressure and damper settings based around his or her weight and ride preferences or remove the suspension bits entirely, should they prefer an unsuspended ride.
InMotion also upgrades the electrical components supporting the powertrain, adding a dual-hall sensor layout for more precise motor control, upgrading the battery management system (BMS) with new algorithms, and adding component redundancy to improve safety.
The V13 Challenger rider platform includes adjustable-tilt pedals, a touchscreen computer, a headlight and tail light, USB and USB-C ports for mobile device charging, an upper safety cage around vital electricals that doubles as a set of lift handles, and a folding trolley handle for rolling the wheel by hand. It rides atop a 22 x 3-in off-road tire, and multi-piece construction makes it easier to break down for repairing a flat or making modifications.
In terms of charging, the V13 has two ports located above the tail light that combine for 1,764 watts. When the owner uses both, the battery charges in 2 to 2.5 hours.
InMotion introduced the V13 Challenger last week, and while the company said it would launch immediately, it does not yet appear on the InMotion website or Amazon store. E Riderz, an InMotion dealer in Australia, has it up for preorder at a special price of AU$5,699. Special preorder pricing is expected to be $3,999 in the US.
