Overview
The King Song F18 is a self-balancing electric unicycle built for both city and off-road riding, with 100mm suspension, UL2272 certification, and app-based controls.
Motor and top speed figures differ across the listing's title and spec copy, with the title citing a 5000W motor and the description citing a 9000W peak with a 75 mph top speed, so treat the higher numbers with some caution until confirmed. What holds steady across both is the 100mm suspension, KingSong app integration, and a lightweight 60.96 lb build for portability.
- 100mm suspension travel for off-road riding
- UL2272 certified, 11-layer safety protection
- KingSong app control, built-in Bluetooth speaker
- Weighs about 60.96 lbs, folds into car trunks and elevators
Who it's for
For riders already comfortable on an electric unicycle who want off-road suspension and app-based beginner mode, not a first-ever EUC purchase.

Performance notes
The 100mm suspension system uses springs or dampers to absorb shocks on rough terrain, aimed at reducing rider fatigue. The KingSong app handles beginner mode and tilt calibration, and an 11-layer safety system protects against over-current and over-voltage conditions. A built-in Bluetooth speaker plays audio during rides.
