Product information
With a unique X-shaped suspension system that allows for up to 4” suspension travel, S18 allows you to turn the suspension on or off as well as adjust the sensitivity. Different pressurization can be adjusted according to rider weight. With an interchangeable component, riders can customize it to fit their personal modification and riding style.
King Song included all of their latest features to make sure S18 riders never left wanting more. Headlights will be 2x stronger than that of the 16X with an automatic sensor that switches between high and low beam. The rear light will display battery level, braking, and turning within one singular unit. Aluminum handle with robust construction means you can comfortably take your electric unicycle anywhere with you without needing to carry it, and it even has a built in sensor to automatically disengage the motor for those times you need to briefly lift your wheel over an obstacle or up a flight of stairs.
King Song is now offering the S18 with Molicel P42A high-discharge cells! One of the main complaints riders reported with the OG S18 was the lack of power the 1110Wh high-capacity LG M50LT packs were able to provide in high-load situations. The P42A model fixes this issue, as these cells can output several times more power than the LG M50LT cells safely. With these two options now available, riders can choose between more range or better performance depending on their riding style and use case for the wheel.
