Overview
The KingSong S18Pro is the higher-spec sibling in this Topfeel-listed lineup, adding 100mm suspension and a 5000W peak motor for a listed 31 mph top speed and roughly 62 mile range.
Where the base S16Pro in this same catalog keeps things simple, the S18Pro adds suspension travel and a stronger peak motor, aimed at riders who want more cushioning over rough pavement and a longer range between charges rather than a lighter, simpler unit.
- 5000W peak motor with 31 mph top speed
- 100mm suspension travel
- Up to roughly 62 mile (100km) range
- UL2272 certified with 11 safety shields
Who it's for
Riders already comfortable on a self-balancing unicycle who want extra range and suspension for rougher city streets. It is not aimed at someone buying their first EUC.
Pros and cons
- 100mm suspension for rough pavement
- Listed range of roughly 62 miles (100km)
- 5000W peak motor for hill climbing
- UL2272 certified with 11 safety shields
- Suspension and extra power likely add weight over the base model
- Still requires real balance practice before it feels stable
Performance notes
The 100mm suspension is the standout spec here, built to absorb rough pavement and potholes that a rigid EUC would send straight into the rider's legs. Paired with a 5000W peak motor, the numbers point to a machine meant for longer, less predictable routes rather than smooth dedicated bike paths only.
