Which has better brakes?

The NIU KQi 300X has the better brakes on paper: dual-action disc brakes on both wheels plus regenerative braking, where the Segway Ninebot Max G2 pairs a front drum with a rear electronic brake. The Max G2's brakes are not in Segway's own G2 spec table; Segway's Max G3 FAQ describes the G2 as a drum and electronic brake combination, and the Amazon listing says front drum and rear electronic. Two mechanical discs give you a friction brake at each end, while the Max G2 has one mechanical brake and relies on the motor at the back. For a 20 mph scooter ridden in traffic or down long hills, this is the difference we would weigh first.

Which goes further on a charge?

The NIU KQi 300X should, because its battery is about 10% bigger: 608.4 Wh (48 V by 13 Ah) against 551 Wh (36 V by 15.3 Ah), on a scooter 4.8 lb lighter. Ebike Oracle estimates the KQi 300X covers about 23 to 28 miles a charge and the Max G2 about 20 to 25 for a 175 to 180 lb rider at full speed. We divide each battery's watt-hours by 22 to 27 watt-hours per mile, the band published full-speed tests show for a 175 to 180 lb rider; we have not ridden either scooter.

The makers' claims point the other way, and they are not measured alike. Segway's 43 miles assumes a 165 lb rider averaging 9.9 mph on pavement at 77°F, and Segway also publishes what it calls range at speed: 28 miles at 20 mph and 25 miles at 22 mph. NIU claims 37.3 miles, measured in its KQi 300 series manual with a 165 lb rider at a constant 9.3 mph. So the only full-speed figure either maker gives is the Max G2's, and on battery size the KQi 300X has the edge.

Which rides better on rough streets?

The Segway Ninebot Max G2 has more suspension: a front hydraulic damper and dual springs at the rear, where the NIU KQi 300X has a front dual-tube hydraulic fork with 45 mm of travel and nothing at the back. The KQi 300X answers with larger tires, 10.5 by 2.5 in against 10 in, and both run tubeless tires that seal small punctures (Segway says up to 4 mm). On cracked pavement, the Max G2's rear springs are the spec that separates them. Both are rated for riders up to 265 lb.

Which is easier to carry and store?

The NIU KQi 300X: 48.7 lb against the Segway Ninebot Max G2's 53.5 lb, and slightly smaller folded, at 46.2 by 21.3 by 21.4 in by NIU's global figures against 47.6 by 22.4 by 23.8 in. Neither is light, so if the scooter goes up stairs every day, weight is worth more to you than any other line in the table. The Max G2 charges in about 5 hours from a built-in charger (the listing says 6); the KQi 300X takes 6.

How fast do they go, and where can you ride them?

Both stop at 20 mph in the US as shipped. Segway sets the Max G2 to about 20 mph from the factory and lets you raise it to about 22 mph in its app; Amazon's title quotes the 22 mph figure without the default. NIU's US store gives the KQi 300X 20 mph on-road, and Amazon's 23.6 mph is NIU's global figure (38 km/h). At 20 mph both sit at New York's 20 mph limit for e-scooters (VTL §114-e) and above California's 15 mph riding limit (Vehicle Code §22411); the Max G2's 22 mph setting takes it past New York's line. Electric scooters are not e-bikes, so the US e-bike classes do not apply.

The makers' own age limits differ: Segway rates the Max G2 for riders 16 and up, and NIU rates the KQi 300X for 14 and up. State law can be stricter: 16 is the most common minimum age among states that set one, California requires a driver's license or instruction permit to ride a motorized scooter (Vehicle Code §21235), and Pennsylvania does not allow e-scooters on public roads.

Are they certified, and have they been recalled?

Segway states its scooters are tested to UL 2272 by TÜV Rheinland; we could not verify it in the certifier's directory. NIU's US store lists UL 2272 for the KQi 300X with no lab named, and the Amazon listing says only that all NIU scooters hold UL certification; we could not verify it in the certifier's directory either. New York City requires UL 2272 for e-scooters sold there, and California requires UL 2272 battery testing for motorized scooters sold there.

No CPSC recall found for the Segway Ninebot Max G2 as of October 2026. The 2025 Segway recall covered the Max G30P and G30LP (about 220,000 units, for a folding mechanism that can fail), not the Max G2, which is a different model; owners of those two can look up the remedy on CPSC's recall list. No CPSC recall found for the NIU KQi 300X as of October 2026.

Who should buy which?

Buy the Segway Ninebot Max G2 if you want the lower price at the time you check (it was the cheaper one on October 18, 2026), suspension at both ends for rough streets, and a maker that publishes its full-speed range. It also lists Apple Find My, traction control, a remote anti-theft alarm and turn signals. Accept heavier carrying (53.5 lb) and a front drum with a rear electronic brake.

Buy the NIU KQi 300X if you want disc brakes on both wheels, the bigger battery and the lighter scooter, and the gap in price is worth that to you. It adds a 25% climb rating against 22% and cruise control in NIU's app; its IP55 rating gives the same water score as the Max G2's IPX5, plus a dust score. Accept front suspension only, and a range claim measured only at 9.3 mph. On Amazon it is listed as the NIU K300X; buy that listing, sold as new.

Frequently asked questions

Is the Segway Max G2 or the NIU KQi 300X better?

The NIU KQi 300X is the better-equipped scooter on paper, and the Segway Ninebot Max G2 the better value when it is the cheaper one, as it was on Amazon on October 18, 2026. The KQi 300X has disc brakes front and rear, a 608.4 Wh battery against 551 Wh, and weighs 48.7 lb against 53.5 lb. The Max G2 has suspension at both ends and a published full-speed range of 28 miles at 20 mph. At our last check the Max G2 was $699.99 (as of Oct 22, 11:10 AM EDT, subject to change) and the KQi 300X $899 (as of Oct 22, 11:10 AM EDT, subject to change).

Which goes further, the Max G2 or the KQi 300X?

The NIU KQi 300X, by about 3 miles on our estimate. Ebike Oracle estimates it covers about 23 to 28 miles a charge for a 175 to 180 lb rider at full speed, against about 20 to 25 for the Segway Ninebot Max G2, because its battery holds 608.4 Wh to the Max G2's 551 Wh. Segway's 43 mile claim is higher, but it is measured at a 9.9 mph average with a 165 lb rider; Segway also gives 28 miles at 20 mph. NIU's 37.3 miles is measured at a constant 9.3 mph with a 165 lb rider. We have not ridden either.

Is the NIU K300X on Amazon the same scooter as the KQi 300X?

Yes. NIU sells it as the KQi 300X, and the Amazon listing calls it the K300X and the upgraded KQi3 Max; the motor (500 W rated, 1,000 W peak), the 37.3 mile claim, the 25% climb, the 10.5 by 2.5 in tires, the 265 lb limit and the dimensions all match NIU's US page. The one figure that does not match is the top speed: Amazon's 23.6 mph is NIU's global figure, and NIU's US store says 20 mph. Buy the listing sold as new, not a renewed one from another seller.

Is the Segway Max G2 part of the Segway scooter recall?

No. The 2025 Segway recall covered the Ninebot Max G30P and G30LP, about 220,000 scooters whose folding mechanism can fail; the Max G2 is a different model. No CPSC recall found for the Segway Ninebot Max G2 as of October 2026, and none for the NIU KQi 300X either. If you own a G30P or G30LP, look up the remedy on CPSC's recall list. Segway states its scooters are tested to UL 2272 by TÜV Rheinland; we could not verify it in the certifier's directory.

How fast do the Max G2 and KQi 300X go?

Both stop at 20 mph in the US as shipped. The Segway Ninebot Max G2 can be raised to about 22 mph in Segway's app, and the NIU KQi 300X is 20 mph on-road per NIU's US store; the 23.6 mph on its Amazon listing is NIU's global figure. At 20 mph both sit at New York's 20 mph line for e-scooters and above California's 15 mph riding limit. Segway rates the Max G2 for riders 16 and up, NIU the KQi 300X for 14 and up.

Which handles hills and rain better?

The NIU KQi 300X claims more on both, by small margins. NIU rates it for a 25% climb against the Segway Ninebot Max G2's 22%, from 500 W rated against 450 W (both peak at 1,000 W). For water, the Max G2 is IPX5 and the KQi 300X IP55: both carry the same 5 for water jets, and NIU's rating adds a dust score. Read each maker's manual for its wet-weather rules before riding in rain.
