Which goes further on a charge?
The KQi 300X, because its battery is 25% bigger: 608.4 Wh against 486.7 Wh. Ebike Oracle estimates about 23 to 28 miles a charge for the 300X and 18 to 22 for the 300P, for a 175 to 180 lb rider at full speed, by dividing each battery's watt-hours by 22 to 27 watt-hours per mile, a band from published full-speed tests. NIU's own claims, 37.3 and 30 miles, come from one footnote in the KQi 300 series manual: a 165 lb rider at a constant 9.3 mph on flat ground at 77°F, which is the E-Save mode's speed. An independent test of the 300P by the review site ERideHero recorded 17.8 miles at full speed with a 175 lb rider.
Which handles hills better?
The KQi 300X. NIU rates it at 500 W with 37 N·m of torque and a 25% climb, against 450 W, 27 N·m and 20% for the 300P, both measured with a 165 lb rider at a steady 5 mph. On hills, that torque gap, 37 against 27 N·m, matters more than the 50 W difference in rated power.
Is the ride the same?
Yes. Both use the same 45 mm dual-tube hydraulic front fork with no rear suspension, the same 10.5 by 2.5-inch tubeless air tire size and the same disc brakes on both wheels plus regenerative braking from the rear motor. NIU markets the 300X's tires as self-healing and makes no such claim for the 300P. NIU calls both "All-Terrain", but its own manual limits both to flat pavement, steps no higher than 0.4 in and gaps no wider than 1.2 in, so neither is an off-road scooter.
Which is easier to carry?
The KQi 300P, by 2.7 lb: 45.97 lb against 48.7 lb, with the same folded size of 46.2 x 21.3 x 21.4 in. Neither is light. If the scooter goes up stairs every day, that small gap matters less than the fact that both are over 45 lb.
How fast do they go, and can you unlock them?
Both are sold at 20 mph in the US. The 300P is 32 km/h (about 20 mph) in every NIU listing we found, so there is no faster version of it to unlock. The 300X is 38 km/h (23.6 mph) in NIU's global table and series manual, which is the figure in its Amazon title; NIU's US store sells it at 20 mph on-road. At 20 mph both sit at New York's 20 mph e-scooter line (VTL §114-e) and above California's 15 mph limit (Vehicle Code §22411), so California riders must keep to 15 mph or below. Pennsylvania does not allow e-scooters on public roads. Scooters are not e-bikes, so the e-bike classes do not apply.
Are they certified, and have they been recalled?
NIU's US store lists both as UL 2272 certified, and the series manual shows a UL mark for the KQi 300P and 300X, without a certificate number or lab. We could not verify either in the certifier's directory. New York City requires UL 2272 for e-scooters sold there. No CPSC recall found for either as of October 2026, and both carry NIU's 2-year warranty on the main body, including battery and motor.
Who should buy which?
Buy the NIU KQi 300P if your round trip is under about 18 miles, your route is mostly flat, and you would rather keep the price difference and carry 2.7 lb less. You get the same ride, brakes and build.
Buy the NIU KQi 300X if you ride further than that, climb real hills, or weigh near the 265 lb limit, where the extra torque and battery earn their keep.

Frequently asked questions
What is the difference between the NIU KQi 300P and the 300X?
The battery and motor. The 300X has a 608.4 Wh battery against 486.7 Wh, a 500 W rated (1,000 W peak, 37 N·m) motor against 450 W (900 W, 27 N·m), a 25% climb against 20%, and NIU's 37.3-mile claim against 30. Everything else is the same: frame, hydraulic front fork, 10.5-inch tubeless tire size, disc brakes front and rear, IP55, a 265 lb limit and 20 mph in the US. The 300P is 2.7 lb lighter.
Is the NIU KQi 300X worth the extra money over the 300P?
If your round trip is over about 18 miles or hilly, yes: its 25% bigger battery gives an estimated 23 to 28 miles at full speed against 18 to 22 for the 300P, and its motor has more torque for climbs. On short, flat commutes the 300P gives the same ride, brakes and build for less money and 2.7 lb less weight.
Which is faster, the KQi 300P or the 300X?
In the US, neither: both are sold at 20 mph. The 300X is 23.6 mph (38 km/h) in NIU's global table and manual, the figure in its Amazon title, while NIU's US store lists it at 20 mph on-road; the 300P is 32 km/h (about 20 mph) in every NIU listing we found, so there is no faster 300P to unlock.
Do the KQi 300P and 300X have the same suspension and brakes?
Yes. Both use a 45 mm dual-tube hydraulic front fork with no rear suspension, 10.5 x 2.5-inch tubeless tires, and mechanical disc brakes on both wheels plus regenerative braking. NIU markets the 300X tires as self-healing and makes no such claim for the 300P.
How far do the NIU KQi 300P and 300X go?
By our estimate, about 18 to 22 miles for the 300P and 23 to 28 for the 300X, at full speed with a 175 to 180 lb rider. NIU claims 30 and 37.3 miles, measured with a 165 lb rider at a constant 9.3 mph on flat ground at 77°F.
