NIU KQi3 Pro: Everything You Need to Know

The NIU KQi3 Pro is a folding kick scooter, not a Class 1, 2, or 3 e-bike. NIU’s US card lists 19.9 mph, a 350-watt rated motor that peaks at 700 watts, a 48-volt 486 watt-hour pack, 31 miles of claimed range, and a weight of 44.75 pounds with the battery in. There is no suspension. The tires are 9.5-inch tubeless pneumatics. The rider limit is 265 pounds. Minimum age on the card is 14. The price on that card is $699, and it is sold out. UL 2272 is printed. IP54 is printed. A full-throttle loop published by Rider Guide measured 18.6 mph and 20.9 miles.

Where it sits in the KQi3 line

The Pro is the middle one. Same 9.5-inch tubeless tires, same four modes — E-Save, Sport, Custom, Pedestrian — and the same app: unlock, cruise, regen strength, over-the-air updates. NIU’s global compare table rounds the Pro’s speed to 20 mph. The US product title says 19.9. Buy the number on the card you are paying, and assume a city that caps scooters at 15 will not care about the extra 4.9.

Thirty-one miles is the brochure

Thirty-one miles on 486 watt-hours is about 16 watt-hours a mile. That is a light rider in a low mode, not Sport with the thumb held down. Rider Guide’s test, first published in June 2022 and still on that page in September 2026, was the other loop: full throttle, stopping for lights. They measured 20.9 miles and 18.6 mph. Four hundred eighty-six divided by 20.9 is about 23 watt-hours a mile. The page says the scooter held about 90 percent of its speed until the last two miles. This desk has not rerun it. Treat 21 as the throttle commute and 31 as the mode NIU did not attach a rider weight to.

The useful pair is 19.9 claimed and 18.6 tested. The range pair is 31 claimed and 20.9 on the throttle.

Brakes, and the line that disagrees

The US product card says dual disc, front and rear, plus regenerative. NIU’s global compare table says a dual disc brake at the front, plus regenerative. Those are not the same sentence. Electric Scooter Insider’s July 2023 first look, with the scooter in the shot, describes dual discs and regen you set in the app to weak, medium, or strong. Look at both wheels before you trust a table. There is no suspension on the card. The 9.5-inch pneumatics are the only compliance. A pothole is the tire and your knees.

What the card is good at

Forty-four and three-quarter pounds with the pack in is a scooter you can carry up a flight if you mean it. Folded height on the card is 19.8 inches. The stem is a two-step latch NIU calls patented. Handlebar length is 21.3 inches, deck length 22.4, deck width 6.7. Ground clearance is 2.9 inches, which is a curb, not a trail. IP54 is splashes and dust, not a storm and not a hose. UL 2272 is the electrical mark on the card. The warranty block is two years on the main body, including the battery, charger, frame, motor, and controller; six months on levers, discs, and the throttle; three months on lights, the bell, fenders, and the kickstand.

It is not a Class 2 e-bike. No pedals. A city that allows bicycles and bans stand-up scooters does not make an exception because the top speed is under 20. The Segway Max G3 is the heavier commuter this desk put first on the scooter list: more motor, a bigger test argument, and a price above this one. The KQi3 Pro is the lighter, slower, cheaper card, when the card is actually in stock.

Who it is for

Buy it if the trip is paved, the rider is over 14, 45 pounds is a weight you will lift, and 20 miles of throttle is enough. Do not buy it for a 31-mile Sport commute. Do not buy it for a dirt path. Do not buy the Max if you wanted the Pro’s weight, and do not buy the Sport if you wanted the Pro’s pack. The US card this desk read was $699 and sold out. A third-party page still printed $799. The cart is the price.
