S18

The KingSong S18 is the company's first suspension electric unicycle (EUC), built around a 2200W hub motor (about 5000W peak) on an 84V system. Its defining feature is an exoskeleton-style frame wrapped around a linkage-driven air suspension that gives roughly 100mm of wheel travel, with stiffness adjustable on the fly to suit terrain and rider weight. The 18-inch, 3-inch-wide pneumatic tire and 1110Wh battery (LG M50LT cells in the standard pack) yield a manufacturer-claimed top speed near 50 km/h and a claimed range of up to about 100 km. Relatively light for its class at roughly 22 kg, the S18 is aimed at riders who want comfort over rough surfaces, though balancing a unicycle remains a serious skill that beginners must learn before riding at speed.
