NIU KQi 100P Electric Scooter

Amazon sells the 100P under two listings, and we checked both on November 7, 2026. They carry the same photo, the same feature list, the same 38.1 lb weight and 20.5-inch width, and Amazon's model field names the 100P on both. The offers differed. One listing was new stock sold by NIU's own Amazon store. The other, cheaper one was a used unit graded Like New by a third-party seller. Before you check out, read the condition line next to the price. NIU's warranty covers the main body, battery included, for 2 years from delivery, but NIU's terms do not say whether that applies to a scooter bought used from another seller, so ask NIU or the seller first.

Two more things to check on the listing. Both Amazon listings show blue fork tubes in their main photo, while NIU's own photos of the Gray 100P show silver ones and both listings name the color as gray, so the fork on the scooter you receive may not match Amazon's picture. And if a listing says 38.8 lb, a foldable handlebar or turn signals, it is the 100F.

NIU rates the rear hub motor at 300 W with a 600 W peak. There are four modes: Pedestrian (3.7 mph), E-Save (9.3 mph), Sport (17.4 mph) and a Custom mode you set in the NIU app. Electric Scooter Guide tested the 100P and recorded 17.6 mph and 0 to 15 mph in 6.4 seconds. Hills are the weak point. NIU's 15% climb rating is for a 165 lb rider at a constant 5 mph. On the 100F, which has the same motor and battery, ERideHero's 175 lb rider averaged 6 mph up an 8% grade and could not get up a 17% hill, and the reviewer suggests riders over about 220 lb avoid hilly routes.

Scooter rules vary by state and often by city. At 17.4 mph the 100P is under the 20 mph ceiling in New York's e-scooter definition (VTL §114-e) and New Jersey's under-19 mph line, but above California's 15 mph limit for motorized scooters (Vehicle Code §22411), so California riders must hold it to 15 mph; the app lets you set a lower top speed. California also requires a driver's license or instruction permit (§21235). Pennsylvania does not allow e-scooters on public roads. Scooters are not e-bikes, so the US e-bike classes do not apply. Check your city's rules too before you ride.

NIU markets a 48 V battery; the manual rates it at 46.8 V and 243 Wh, which matches 46.8 V × 5.2 Ah. NIU claims 18 miles and says how it got there: a 165 lb (75 kg) rider at a constant 9.3 mph on a flat road at 77°F with a full battery. That is the E-Save speed cap. Our own estimate for a 175 to 180 lb rider at full speed is about 9 to 11 miles: 243 Wh divided by 22 to 27 Wh per mile, the middle half of 32 published full-speed range tests of commuter scooters. Electric Scooter Guide covered 11 miles on the 100P (it does not give the rider's weight), and ERideHero's tests of the 100F, below, land in the same place. Plan on a round trip of under about 10 miles.

ERideHero, with a 175 lb rider on the KQi 100F (same battery and motor), measured:

A full charge takes 5 to 6 hours on the 54.6 V, 1 A charger, per NIU, and the app can stop charging at 80% or 90% to spare the battery.

The 100P rides on 9.5 × 2.3-inch pneumatic tires with inner tubes (NIU recommends 45 to 50 psi) and a front spring fork with 36 mm of travel; there is no rear suspension. Tubed tires ride softly, but a puncture means changing or patching the tube. Braking is a front drum plus the motor's regenerative brake on a single lever, and the regen strength is adjustable in the app. ERideHero stopped the 100F from 15 mph in 12.8 ft. NIU rates the scooter IPX5 in its US spec table and manual. Lighting is an LED headlight, a brake light and side reflectors, with no turn signals. Electric Scooter Guide's complaints were the battery size, the tubed tires and a deck that feels a little plasticky.

Read the marketing with care. The Amazon copy pitches it "from city to off-road", but NIU's own manual limits riding to flat pavement, curbs no higher than 0.4 in (1 cm) and gaps no wider than 1.2 in (3 cm). The stem folds in two steps, and folded the 100P measures 45.4 x 20.5 x 19.9 inches. The handlebar keeps its full 20.5-inch width, so it takes more room in a hallway or car trunk than the 100F, which folds to 7.2 inches wide. At 38.1 lb it is a manageable carry for most adults. The rider limit is 265 lb, and NIU's age floor is 14.

NIU states its KQi 100 scooters are UL 2272 certified, the manual carries a UL mark for the KQi 100P and 100F, and both Amazon listings say "UL Certified". None of them names a standard number, certificate or file number, and we could not verify it in a certifier's directory. UL 2272 is the fire and electrical safety standard for scooters, and since September 16, 2023, New York City's Local Law 39 has required e-scooters sold there to be certified to it (NYC DCWP). If your building asks for proof, ask NIU for the certificate before you buy.

No CPSC or SaferProducts recall found for the NIU KQi 100P or any NIU kick scooter as of November 7, 2026 (CPSC recalls). Our electric scooter safety guide explains how to check a listing's claim.

• NIU KQi 100F ($449 as of Nov 7, 4:11 PM EST, subject to change): the same scooter plus handlebars that fold to 7.2 inches wide and bar-end turn signals with a hazard mode, at 38.8 lb. Worth the difference if you store the scooter in a narrow hallway or closet, or ride in traffic after dark.
• NIU KQi2 Pro ($199.99 as of Nov 7, 4:11 PM EST, subject to change): the same 300 W rated, 600 W peak motor and 17.4 mph, a bigger 365 Wh battery and 10-inch tubeless tires, but no suspension, IP54 and a 220 lb rider limit. ERideHero measured 19.8 miles on it against 11.38 on the 100F at the same pace. Pick it for range; pick the 100P for the front fork, IPX5 and the higher rider limit. NIU's US store tags the KQi2 Pro OLD.
• NIU KQi 300P ($649 as of Nov 7, 4:11 PM EST, subject to change): twice the battery (486.7 Wh), a 450 W rated motor, 20 mph, 10.5-inch tubeless tires, a hydraulic fork and disc brakes front and rear, at about 46 lb. The pick if your commute is longer or hillier.
• Hiboy S2 ($299.98 as of Nov 7, 4:10 PM EST, subject to change): a lighter budget scooter (35.5 lb) with a slightly bigger 280.8 Wh battery, 19 mph, solid 8.5-inch honeycomb tires and rear spring shocks, IPX4 and a 220 lb limit.

Buy the KQi 100P if your trip is flat and under about 10 miles round trip, and you want front suspension and air tires from a brand that publishes its spec sheet, manual and range test conditions. If you will store it in a narrow space or ride in traffic after dark, the 100F's folding bar and turn signals are worth paying for.

Skip it if your route has steep hills, you weigh over about 220 lb and ride hills, or you need more than about 5 miles each way. The KQi 300P or a 400 to 500 Wh scooter from our best electric scooters for commuting guide will serve you better. Skip it too if your building needs a UL 2272 certificate number, since NIU has not published one.
