- Built for City Commutes and Off-Road Adventures The S19PRO is designed for riders who need one wheel to handle multiple scenarios. With a top speed 60 km/h (about 37 mph) and up to about 83miles of range, it can easily handle daily commuting and weekend trail riding. The 18×3.0 inch wide tire delivers better grip and stability on pavement, gravel, and light off-road terrain, making this electric unicycle a true step up from regular hoverboards.
- 3500W Innovative Hollow Motor with Strong Climbing Power Powered by a 3500W innovative hollow motor and up to 6500W peak output, the S19PRO offers stronger power, higher efficiency, and rapid acceleration. It can take riders up to 120 kg (about 265 lbs) and tackle slopes up to around 40°. For experienced riders looking for a one wheel hoverboard with serious performance, this unicycle delivers the torque and speed needed for demanding city and off-road rides.
- Adjustable Spring Suspension for All-Terrain Comfort Equipped with a DNM AOY 36RC suspension and 90mm EUC suspension travel plus about 57mm air chamber travel, the S19PRO is built to absorb impacts from stairs, curbs, and uneven mountain trails. The spring-adjustable suspension allows you to tune the setup based on your weight and riding style. Compared with many standard hoverboards, this electric unicycle offers a much more comfortable and controlled ride across various surfaces.
- 1776Wh Samsung Battery with Smart BMS for Long-Range Riding The S19PRO uses 96 pcs SAMSUNG 50S cells for a total battery capacity of 1776Wh. Under test conditions, it can reach up to about 150 km of mileage, making it ideal for long-distance city cruises or all-day rides. The intelligent BMS (battery management system) provides balancing, overcharge, overcurrent, short-circuit protection, and abnormal status analysis. With a 100.8V 5A charger, charging takes about 4–5 hours, and using two same chargers can cut that time roughly in half—perfect for riders who use their onewheel frequently.
- Smart Protection, RGB Lighting & Practical Details S19PRO is packed with safety and convenience features: a lift sensor that stops tire rotation when you pick up the unicycle, roll protection at around 45° (angle adjustable via the app), over-speed buzzer or voice alerts with pedal tilt-back, low-power gradual speed limiting, and high-temperature protection for both motherboard and motor. The motherboard uses silicone sealing for improved waterproof performance, while the anti-slip spiked pedals keep you firmly connected in all weather. A cool RGB rear light strip, 178 LED lamp beads with aurora effects, Bluetooth speakers (bass + tweeter), adjustable multi-beam headlights, and a large 32×32 matrix display for speed, power, and fault codes all combine to make this hoverboard for adults not only powerful, but also smart and stylish among Self Balancing Scooters.
