Overview
A self-balancing electric unicycle built for high-speed, long-range solo riding. The King Song model pairs a UL2272-certified electrical safety system with a suspension setup meant to smooth out rough pavement and light trail riding.
The title lists a 5000W rated motor while the bullet copy describes a 9000W peak output, which is typical for EUCs where sustained and burst power differ, so 5000W is the figure to plan around for continuous climbing and cruising. Top speed is listed at 75 mph, a figure that requires real riding experience and full protective gear given the injury risk of unicycle-style vehicles at that speed. Range is listed at up to 83 miles in the title, while the app control and built-in Bluetooth speaker are aimed at everyday usability rather than the speed spec.
- Rated 5000W motor, 9000W peak
- Top speed listed at 75 mph
- Range listed up to 83 miles
- Aluminum alloy, ABS, and PC construction
Who it's for
Experienced EUC riders who want maximum range and speed for long commutes or touring, and who already ride with a helmet and pads. Not for first-time EUC riders, since the top-speed capability and 61-pound weight make this a demanding machine to learn on.
Strengths and trade-offs
Drawn from this product's published specifications.
- UL2272-certified electrical safety with 11-layer protection
- 100mm suspension smooths rough urban pavement
- App control with a beginner mode and tilt calibration
- Built-in Bluetooth speaker
- 75 mph top speed demands real riding experience and full protective gear
- 60.96 lbs is heavy to carry over distance
- Motor power figures differ between listing fields, 5000W rated versus 9000W peak
Performance notes
The 100mm suspension is meant to absorb bumps and cracks on city streets, reducing the fatigue that comes from riding a rigid EUC over rough pavement. UL2272 certification plus an 11-layer protection system covers over-current and over-voltage faults, which matters given how much power a 75 mph top speed requires. At 60.96 lbs, it is portable enough to fit into an elevator or car trunk but heavy enough that lifting it repeatedly during a commute is real effort.
