Overview
One-wheel self-balancing electric unicycle built for adult commuters, with a listed top speed of 37 mph, a 48 degree climbing angle and up to 55 miles of range. App control lets riders check status and adjust settings from a phone.
This is a single-wheel unicycle, not a two-wheeled scooter or e-bike, so it demands active balance from the rider regardless of the electronics on board. King Song positions the learning mode as a way to ease new riders in, but the top-end numbers point squarely at experienced unicyclists rather than first-time buyers. No rating or review data is attached to this listing, so range and speed figures should be treated as maker claims until confirmed elsewhere.
- Self-balancing one-wheel electric unicycle
- 37 mph top speed, 48 degree climbing angle
- Up to 55 miles max range
- Smartphone app control
Who it's for
Riders who already have electric unicycle experience and want a commuter-grade wheel with higher speed and climbing headroom than entry models. Not a starting point for someone who has never ridden a self-balancing one-wheel device.
Strengths and trade-offs
Drawn from this product's published specifications.
- Listed 55 mile range for longer commutes
- 37 mph top speed for experienced riders
- App control for monitoring and customization
- 48 degree climbing angle for hilly routes
- No rating or review history attached to this listing
- Single-wheel design has a real learning curve
- Top speed and range are manufacturer figures only
Performance notes
The 48 degree climbing figure and 37 mph top speed both depend on the self-balancing motor and gyroscope working together to keep the single wheel upright under load, the core mechanism of any electric unicycle. App control adds monitoring and customization on top of that base function rather than changing how the wheel itself balances.
