Price bands for the electric unicycles run from the maker's sale price to its regular price; the scooter's band is around the Amazon price seen on October 9, 2026, and prices change often. Segway's range note is unusually honest: its page gives the 43-mile "theoretical" figure and, separately, 28 miles at 20 mph and 25 miles at 22 mph.

Learning curve and control

This is the scooter's biggest advantage. A scooter has handlebars with the throttle and brake controls on them, and Segway lists traction control (TCS anti-skid) on the Max G2. An electric unicycle has none of that: you balance on two pedals, speed up by leaning forward, and, in InMotion's words, "to brake, shift your weight backward or lower your body."

The learning time is shorter than many expect. InMotion's FAQ says most people learn the basics within the first hour, and King Song's beginner guide plans the first session as 10 to 20 minute blocks. InMotion's V12S manual asks for an open, flat area of at least 4 by 4 meters, a skilled assistant, and a helmet and protective gear. Budget a few sessions in an empty lot before you ride anywhere with traffic; our Onewheel comparison covers how the other balance-based option differs.

Size, weight and storage

Folded, the Max G2 is 47.6 inches long and 23.8 inches tall. The V9 stands 24.9 inches tall in a footprint of 18.8 by 7.4 inches, and the 16S Pro is 19.9 inches tall. That difference decides whether the vehicle fits under a desk, in a small car trunk or beside you on a crowded train.

Weight is closer than size. The V9 (50.7 lb) and Max G2 (53.5 lb) are within 3 lb of each other, while the 14D Pro is 21.5 lb lighter than the scooter and the 16S Pro 15.1 lb lighter. Many electric unicycles have a trolley handle so you can roll them like luggage.

Range, battery and charging

At similar prices, the electric unicycles carry more battery: the V9's 750 Wh is 199 Wh more than the Max G2's 551 Wh, and the 16S Pro's 840 Wh is 289 Wh more. Range claims are harder to compare because the conditions differ. InMotion's V12S manual defines its typical range at a 90 kg (198 lb) load, 25°C (77°F) and 20 to 40 km/h (12 to 25 mph) on a flat paved road, while most product pages, including the V9's, give no conditions. Work your own trip out with the range calculator.

Charging is similar at the low end: about 5 hours for the Max G2 and the V9, about 3.5 hours for the 14D Pro's smaller pack, and about 7 hours for the 16S Pro on its stock 2 A charger.

Ride comfort, hills and weather

The Max G2 pairs 10-inch tubeless self-sealing tires with front hydraulic and rear spring suspension, and Segway rates it for most flat roads and cobblestones, with a 22% maximum slope. The electric unicycles roll on larger 14 to 16-inch tires; the V9 adds 60 mm of suspension and InMotion lists a 30° hill-climb angle, while King Song lists 32° for the 14D Pro. Treat all climbing figures as maker maximums, not what a heavy rider will manage on a long hill.

For rain, the ratings are similar: IPX5 on the Max G2 and 14D Pro, IPX6 on the V9 and IP54 on the 16S Pro. Segway's own FAQ says its scooters can handle light rain but should not be submerged, King Song's pages say its wheels are not waterproof, and InMotion and King Song (in its warranty policy) both exclude water damage.

Certification and where you can ride

Segway's Max G2 page says the scooter was tested and certified by TÜV Rheinland to the UL 2272 standard, and King Song lists UL 2272 for the 14D Pro and 16S Pro. Rules on where each may be ridden vary by state and city, and the two vehicles do not always fall under the same rules; check yours in our guide to where electric unicycles are legal before you buy. The CPSC's advice applies to both: wear a bicycle helmet every ride, and charge with the maker's charger while you are home and awake.

Who should buy which

Buy a scooter like the Max G2 if you want the shortest path from box to commute, prefer handlebar controls, and have room to store a 47.6-inch folded frame. Buy an electric unicycle if you need to carry or stow it in small spaces, want more battery at a similar price, or want the lighter weight of a 14-inch wheel like the 14D Pro, and you will practice first.
