NIU kqi air carbon fiber foldable scooter is super fast and super light, especially if you commute every day and need to take the train and bus. It’s perfect for long commutes involving both the train and bus. With a scooter, you no longer have to wait for the bus — you already have your own ride, It’s easy to fold when you need to use the stairs, and you don’t have to wait for the elevator because you can carry your scooter. If you’re in a hurry, you can also carry it since it’s lightweight.. The downside of this scooter is that sometimes you need to check the screws on the handlebar, because since it’s made of carbon fiber, they can loosen a bit faster. So you should always check if the screws are tight — but not overly tight. That’s the only downside for me, but you still need to be careful.

You'll never find a spare tire. I searched everywhere, from the official website to Aliexpress, and no sealants or rubber adhesives can solve the issue of the tire deflating at the rim. The scooter is marketed as very lightweight, and that's true, but this lightness makes it frustrating to use as the scooter tends to pop wheelies every time it starts. Overall, the concept is very promising, but the execution, engineering solutions, and after-sales support are disappointing not only for this model but for the brand as well. I tried to replace my old Ninebot F30 with it, but I still rely on the F30 after two years with no issues other than changing the spare tire that came with it. The Niu Air, however, just sits around because I have no desire to pump up the tire twice a day.

As product, it's light. But like most people here said, The after sales service is horrible. Don't be like me and ignore this complaint because it's true and i now regret buying this scooter. The front wheel was wobbly out of the box, apparently a common problem. Instead of sending me a replacement wheel, they rejected my claim (only found out after i had to send them a second email) and said i must send in the entire scooter. Unacceptable, impractical solution. They just want you to go away after you buy the scooter. Therefore, the scooter can't be easily maintained. Very disappointed. DON'T BUY.

I recently got my hands on the NIU - KQi Air Carbon Fiber Foldable Electric Kick Scooter and I'm absolutely loving it! This scooter is a game-changer when it comes to convenience and practicality. First off, the carbon fiber construction makes it incredibly lightweight, so I can effortlessly carry it around or fold it up for easy storage. It's perfect for commuting, especially when you need to hop on trains or buses where space is limited. Another great aspect is the battery life. The KQi Air comes with a long-lasting battery that gives me a decent range of up to 22 miles on a single charge. And recharging is a breeze - it takes only a few hours to replenish the battery, so I don't have to wait long to get back on the road. I also appreciate the thoughtful design elements. The control panel is simple and intuitive, allowing me to effortlessly switch between riding modes or adjust the speed. The accompanying smartphone app is a great bonus too, as it provides real-time ride tracking and allows me to lock the scooter remotely. Overall, the NIU - KQi Air Carbon Fiber Foldable Electric Kick Scooter is an absolute joy to ride. It's lightweight, convenient to fold, and provides a comfortable and safe riding experience. If you're looking for a reliable and stylish electric scooter for everyday use, I highly recommend the KQi Air!

worked perfectly for about 3 months. the scooter no longer powers on. the display screen is dead and the NFC card, bluetooth/ app or power button no longer work. i've contacted niu after sales for replacement parts and still have not heard back from them. i also have the kqi2 pro and that scooter has been and is still running flawlessly. others have been having the same problem with the air and i would not recommend it.
