Kingsong S18 Electric Unicycle


Kingsong S18 Electric Unicycle


Available with 3-4 weeks delivery

A real departure from accepted conventions in EUC design, the Kingsong S18 takes its cues from sports bikes. The exposed suspension geometry is scantily clad with detachable fairing panels in an effort to cut weight. Battery and controller components are suspended along with the rider to cut un-sprung weight. The result is a super-agile performance wheel that brings a new dimension to off-road riding.

  • Description

    With the S18 electric unicycle, Kingsong chose to forgo the rugged utilitarian direction taken by the Veteran Sherman and perhaps its own KS16X to bring us an entirely new style of EUC.   The S18 sheds the obligatory moulded plastic carcass of its rivals and hangs components off exposed suspension geometry. This helps the S18 to save weight – at just 21.7kg, the wheel is usefully lighter than its contemporaries.

    The adjustable DNM air-shock can be tuned to the rider and adjusted for riding style and terrain. For super-smooth roads, the suspension can be dialled-out completely. For fast road-riding, you can run with slower rebound for tight control if you hit a bump. And for off-road, you can speed up the shock to allow you to float over sequences of bumps.

    The wheel is set-up to suit aggressive riding so Kingsong opted for a 1110wh battery pack to avoid adding unnecessary weight. However, the powerful new 2200w motor and controller combination is efficient enough to offer riders up to 62 miles of range should they need it. A new lighting system features automatic dipped beam and full beam for safer night riding.
