The NIU KQi 100F is the scooter under $500 that packs away smallest: its handlebars fold down, so the whole scooter folds to 45.4 by 7.2 by 19.9 inches, narrow enough for a hallway or a car trunk, at 38.8 lb. NIU rates it at 300 W (600 W peak) and 17.4 mph, with a 36 mm front spring fork, 9.5-inch air-filled tires with inner tubes, a front drum plus a regenerative brake, bar-end turn signals with a hazard mode, IPX5, a 265 lb limit and riders 14 and up. NIU's 2-year warranty covers the battery, motor, frame and controller, the only warranty among our picks that names the battery for two years. The battery itself is the catch, at 243 Wh. NIU claims 18 miles at a constant 9.3 mph with a 165 lb rider; we estimate about 9 to 11 miles at full speed, and ERideHero's 175 lb tester measured 9.98 to 13.87 miles, depending on speed.
Hills are its weak point. NIU's 15% climb rating is for a 165 lb rider at a constant 5 mph, and ERideHero's tester averaged 6 mph up an 8% grade and could not climb its 17% test hill. NIU markets it for off-road riding, while its own manual limits riding to flat pavement, and tubed tires can puncture. On Amazon, a listing priced far below the 100F is the KQi 100P, with a fixed handlebar and no turn signals, so check that the title says 100F and the weight 38.8 lb. The listing states UL 2272; NIU states it too and its manual shows a UL mark, but no certificate or file number is published, and we could not verify it in a certifier's directory. No CPSC or SaferProducts recall found for the NIU KQi 100F or any NIU kick scooter as of October 25, 2026. At 17.4 mph it is under New York's and New Jersey's lines and above California's 15 mph limit.
Who it suits: riders with a flat trip of under about 10 miles round trip who store the scooter in a small apartment or a car. Skip if your route has steep hills. Read the NIU KQi 100F review.
