Overview
The King Song S22PRO is an electric unicycle rated for a 200 km (about 124 mile) range, an 8500W peak motor, and 130mm of suspension, aimed at riders who want one wheel that can handle both city streets and off-road terrain.
It's UL2272 certified for electrical safety and King Song lists 11 integrated safety shields against over-current and over-voltage conditions. Top speed is listed at 43.5 mph, which puts this well past beginner territory even though the company markets beginner and experienced modes through its companion app.
