More from this brandAll King Song unicyclesOverview
The KingSong KS-16SPro is a self-balancing electric unicycle rated for a 45-mile range and a 25 mph top speed, aimed at commuters who want a single-wheel EUC rather than a two-wheel e-bike. It carries UL2272 certification and pairs with the Topfeel app for beginner-mode calibration.
This is the larger, longer-range sibling in KingSong's Topfeel-branded lineup (see the 14DPro elsewhere in this catalog for the compact version). The 35-degree climbing rating and 25 mph top speed put it toward the higher-performance end of consumer EUCs, which also means the learning curve is steeper than a scooter or bike. Riders still building balance skills may want to start on a slower unicycle.
- UL2272 certified with 11 safety shields
- 45-mile max range, 25 mph top speed
- 35-degree hill climbing
- Topfeel app with beginner mode and tilt calibration
Who it's for
Riders who already have some EUC or skateboard balance experience and want a commuter-range unicycle for city trips. Not a first electric vehicle for someone who has never ridden a self-balancing device.
Pros and cons
- 45-mile rated range for full-day commuting
- UL2272 certification with fall-stop and overspeed alerts
- App-based beginner mode for learning the balance point
- Folds down small enough for car trunks and elevators
- 25 mph top speed demands real EUC experience
- No rating or review data yet to confirm real-world durability
Performance notes
Range and speed come from a battery pack sized for 45 miles, with the motor delivering a 35-degree hill-climbing rating. KingSong lists 11 integrated safety shields plus fall-stop protection and overspeed alerts, features meant to intervene before the wheel cuts out from under the rider at speed. The Topfeel app handles tilt calibration and includes a beginner mode that caps output while riders learn.
