KingSong S19 Pro

KingSong S19 Pro is an electric unicycle that pushes the boundaries of personal mobility. With a top speed of 60 km/h, a motor power of up to 6,500 W, and a range of up to 150 km, it ranks among the absolute best in the world of modern electric unicycles. This model is designed for riders who demand more — more power, more comfort, and more freedom. Thanks to its advanced suspension, high-capacity 1,776 Wh battery with 88.8 V DC voltage, and innovative design, the S19 Pro is an ideal choice for daily commuting, long trips, and sporty riding. A maximum climbing capability of up to 40° makes it a strong partner even in challenging terrain. A total weight of around 33 kg ensures stability, while the construction can support riders up to 120 kg.

Performance and Range

The heart of the KingSong S19 Pro is a powerful electric motor with a nominal output of 3,500 W, reaching up to 6,500 W at peak. Such power allows it to reach speeds of up to 60 km/h, making this unicycle not just a means of transport but also a sporting machine. Thanks to the Samsung 50S 21700 battery with a capacity of 1,776 Wh and a voltage of 88.8 V DC, the S19 Pro reaches a real-world range of up to 150 km on a single charge. Charging is fast — using the dual GX-16-5 port, the battery can be fully charged in approximately 6 hours. The unicycle can handle inclines up to 40°, meaning it can easily conquer steep hills. The entire system is optimized for efficient energy use, extending battery life and increasing reliability.

Construction and Equipment

The KingSong S19 Pro combines elegant modern design with a focus on ergonomics and practicality. Its compact dimensions of 540 × 320 × 790 mm and robust high-strength frame provide stability and durability during daily use. Large 18-inch tires (18 × 3″) offer excellent cushioning and grip on various surfaces, from asphalt to light off-road terrain. Thanks to the adjustable pedal height from 128 mm to 190 mm, riders can adapt their position to their riding style. The pedals, sized 277 × 130 mm, are anti-slip and comfortable even on long routes. The unicycle is equipped with a dual charging port GX-16-5, allowing fast charging with a current of 5 A. A full recharge takes approximately 6 hours, which is excellent for a Samsung 50S 21700 battery with a capacity of 1,776 Wh. KingSong also included advanced LED lighting, brake lights, ambient effects, and an intelligent diagnostic display. Of course, Bluetooth connectivity and a mobile app allow riders to monitor speed, range, battery status, and riding modes.

Safety, Comfort and Practicality

Safety has always been a key priority for KingSong — and the S19 Pro model only reinforces this. An advanced braking system with immediate response, bright LED lights, and integrated turn signals ensure maximum visibility. Stability is enhanced by the wide 18-inch tire, which perfectly absorbs vibrations and allows precise control during every maneuver. The internal temperature and voltage monitoring system protects the battery from overheating or overcharging, while the powerful motor with a nominal output of 3,500 W and a peak output of 6,500 W responds smoothly without the risk of overload. The construction is resistant to shocks and impacts, the pedals feature an anti-slip surface, and the intelligent balancing system assists in sudden loss of stability. With a range of up to 150 km, it handles long trips with ease, while remaining extremely compact and portable. With packaging dimensions of 667 × 362 × 818 mm, it can be easily transported in a car or stored in an apartment. Riders between 150 – 200 cm tall will find an optimal riding position and stability even at higher speeds.

Our Evaluation

Compared to previous models such as the KingSong S18 and S22 Eagle, the S19 Pro represents an ideal balance of performance, weight, and design. The S19 Pro is lighter than the S22 (33 kg vs. ~40 kg), yet offers nearly the same power and improved maneuverability. Compared to the S18, it delivers significantly higher performance, a larger 1,776 Wh battery capacity, a higher top speed of 60 km/h, and a longer range of 150 km. The new suspension system and enhanced LED lighting give the S19 Pro a professional character, making it a model perfectly suited for demanding riders and technology enthusiasts.
