Simple Battery: Fast Charging
The 115.4Wh LG battery charges fully in 2–3 hours and provides up to 7.5 mi (12 km) of range. This gives children plenty of riding time for short trips and practice sessions.




Basketball-Inspired Design: Playful Learning
The unique basketball appearance transforms the KingSong S9 from a transport device into a toy that children love. This familiar design reduces learning anxiety and increases confidence. The bright orange colour and round shape make it instantly recognisable and fun to carry around.
The 10-inch removable tyre design simplifies maintenance for parents. Instead of complex repairs, the entire wheel unit can be replaced easily. This innovative approach reduces downtime and extends the unicycle's lifespan.
Aviation-Grade Frame: Built to Last
Despite its lightweight design, the KingSong S9 electric unicycle features an aviation-grade aluminium alloy frame tested to withstand 1102 lbs (500 kg) of static pressure. This robust construction ensures durability even with frequent drops and bumps. The frame's strength doesn't compromise portability.
Moreover, the KingSong S9 includes multiple safety systems: automatic speed limitation when battery drops below 20%, over-temperature protection, and tilt-back warnings for exceeding safe speeds. These features work together to prevent accidents while children develop their riding skills. The gentle incline angles are less demanding for beginners.




Colourful Light Display, Smart App Integration
The programmable LED light system allows children to customise colours and patterns, adding personality to their ride. The bright, clear display helps children learn while staying visible to others.
The KingSong app connects via Bluetooth, allowing parents to monitor riding statistics, adjust speed limits, and track battery status. Real-time monitoring provides peace of mind while children explore independently. Parents can gradually increase speed limits as skills improve.
Long Battery Life: Extended Play
The LG battery provides years of reliable service with 600 charge cycles maintaining over 80% capacity. The efficient power management system maximises range while preventing over-discharge. The magnetic charging port makes connecting simple enough for children to handle themselves, encouraging responsibility.
