Segway Ninebot Max G3 Electric Scooter

Segway rates the motor at 850 W continuous and 2,000 W peak, with four modes (ECO, DRIVE, SPORT and SPORT+), a Boost mode and about a 30% climb. Its 20 mph factory top speed is at the 20 mph line in New York's e-scooter definition (VTL §114-e) and above California's 15 mph limit for motorized scooters (Vehicle Code §22411); unlocked to 28 mph, it is 8 mph past New York's line and nearly double California's limit. Scooters are not e-bikes, so the US e-bike classes do not apply. Segway's own page warns that several states cap on-road scooter speed and tells riders to use a lower mode where 28 mph is not allowed. In August 2026 New York City sent cease-and-desist orders to 42 online retailers, Amazon among them, over stand-up scooters that can exceed 20 mph. California also requires a driver's license or instruction permit, and Pennsylvania does not allow e-scooters on public roads.

The battery is 46.8 V and 12.75 Ah, which Segway states as 597 Wh, and the pack itself is rated IPX7. Segway rates range by mode, each at that mode's top speed with a full battery, a 165 lb load (give or take 11 lb), about 77°F and pavement: about 50 miles in ECO (the headline, quoted at 10 mph), 40 in DRIVE, 34 in SPORT and 25 in SPORT+. We give no estimate of our own for the G3: the app unlock reaches 28 mph, above the 24 mph limit of our method, because scooters in the 28 mph class use more energy per mile than our band assumes. Segway's own figure for SPORT+, its fastest mode, is about 25 miles. Charging takes about 3.5 hours on the built-in charger, or about 2.5 with a second DC charger, both measured on 220 V.

The G3 rides on 11-inch tubeless self-sealing tires (Segway says a jelly layer seals punctures up to 4 mm) at 42 to 48 psi, with a twin-tube hydraulic front shock and adjustable dual hydraulic rear shocks. It stops with front and rear disc brakes; Segway's FAQ calls them dual-piston and claims ABS, though the spec table lists only the two discs. The body is rated IPX6, and Segway notes that immersion damage is not covered by the warranty. It weighs 54.2 lb, folds to 48 x 23.2 x 23.3 inches and carries up to 286 lb. Segway recommends riders aged 16 to 55 and at least 5 ft 3 in tall. Lights include a 6 W headlight that switches on and off by itself, a brake light and underglow lights that flash with the turn signals. The app adds traction control (off by default), AirLock auto-unlock and Apple Find My.

Segway states its scooters are tested to UL 2272 by TÜV Rheinland; we could not verify it in a certifier's directory. On the G3 page that statement sits in the product-warning block; the Amazon listing says the same, and its title adds UL 2271, which Segway's page does not claim. UL 2272 is an electrical fire and shock standard. New York City requires it for e-scooters sold there (Local Law 39), California has required UL 2272 battery testing for scooters sold since January 1, 2026 (SB 1271), and a rule the CPSC proposed in June 2026 would adopt it for stand-up and seated e-scooters nationwide; it is not yet law. The standard does not test brakes or the folding stem. No CPSC recall found for the Segway Ninebot Max G3 as of October 2026. Segway's March 2025 recall of about 220,000 Max G30P and G30LP scooters, over their folding mechanism, does not cover the G3 or the G3 Plus (CPSC notice).

• KuKirin G2 ($599 as of Oct 22, 11:10 AM EDT, subject to change): the cheaper route to 28 mph, reached without an unlock, with an 800 W rated motor, a bigger 748.8 Wh battery, spring suspension and disc brakes at both ends. It weighs 57 lb, is only IP54, and its UL 2272 claim names no lab.
• Segway Ninebot Max G2: the non-Plus Max that Segway still sells new, with a 551 Wh battery (we estimate 20 to 25 miles), a hydraulic front damper and rear springs, 10-inch self-sealing tires and IPX5, at 53.5 lb. It gives up the G3's discs (it has a front drum and rear electronic brake), its 30% climb and its 28 mph unlock. For a rider held to 20 mph anyway, the G2 covers most of the same ground, and Segway still sells it new.
• NIU KQi 300X: about the same battery (608.4 Wh against 597), front and rear discs with regenerative braking, a hydraulic front fork and IP55, at 48.7 lb, 5.5 lb lighter. NIU's US store lists 20 mph, and it has no rear suspension.
• Segway ZT3 Pro ($799.99 as of Oct 22, 11:10 AM EDT, subject to change): the same 597 Wh battery size in Segway's off-road scooter, with 11-inch off-road tubeless tires, disc brakes at both ends and a 1,600 W peak motor. It ships at 24.9 mph rather than 20 and weighs 65.5 lb against 54.2.

Buy the Max G3 if you are a heavier rider (up to 286 lb), ride hills, and want disc brakes and hydraulic suspension at both ends, while the Amazon listing still has stock. Skip it if you want a model Segway still sells: its US store lists the G3 as end of life and sells the Max G3 Plus (717 Wh) in its place, and the Max G2 is still on sale there with a similar battery. Skip it too if 28 mph is the draw. By the National Conference of State Legislatures' count, 17 states cap a scooter's built-in speed at 20 mph, and our range estimate does not cover riding above 24 mph. And skip it if you carry it up stairs: it weighs 54.2 lb. Our guide to the best electric scooters for adults ranks it against the field.
