Style: 100F Grey - 600W/ 17.4MPH/ 18Mi
Let me just say this: the NIU K100F/K300X/AIR Electric Scooter is an absolute BEAST. My two teenage boys and I ride this thing everywhere—into town, to the store, around the neighborhood, and even on trips along the Cape Cod Canal. At this point, I’m pretty sure the scooter gets more fresh air than I do. Power? Oh, it’s got power. This thing has 600W–900W of “hold on tight and pray you charged your phone for GPS” power. It zips up hills, cruises on flats, and makes me feel way cooler than a grown adult should feel on a scooter. Battery life? Amazing. I swear this thing charges once, then runs for three days straight out of pure determination. We ride it all over creation and it still comes back with enough juice to judge my driving. Range? Perfect for the boys, perfect for me, and perfect for pretending we’re in a high-speed chase… at a reasonable, parent-acceptable speed. The best part? My teens actually want to hang out with me now. They see me grab the scooter key and suddenly they’re like, “Dad, wait for us!” I don’t question it. I just enjoy the moment. If you’re considering this scooter—stop considering. Buy it. Ride it. Let it improve your life in ways therapy can’t. 10/10 — would absolutely buy again and may or may not fight my kids for riding time.

This product is very nice, well built, collapses easy, and pleasing to look at. The wide board is awesome for both my feet, side by side, pointed forward. The build took about 5 minutes and then I was off on a trial run. While some have complained you need an app for the scooter to function, that is not true. The app allows you to register via Bluetooth for updates and to digitally lock the scooter. You can also track rides and speed, elevation and change characteristics of the scooter via the app if you so choose. You absolutely do not need the app open or phone on you to operate if you don’t want to. Personally I like the app because it shows a map you can use to find locations. You will need a phone mount for that though. The only reason I did not give five stars for all is because I’m bleeding power a bit quicker than I thought. From 20%, it took about 6 hours to charge but that is a lot of riding to get it that low. It easy charges to 100% while I sleep. I would say that I will need to charge about every 3-4 days under current usage. Very fun and great over bumps and rough portions of road/sidewalk/dirt roads, breaks are touchy but good. Overall, very happy with this scooter! For reference, I’m 6’1” and 215 and my scooter still sustains the max of 22 mph on flat and slight incline terrain.

As an owner of multiple electric scooter models and brands over the years, I was looking forward to my NIU KQi3 Max experience. Unfortunately, while my initial few months of ownership were very positive, the breakdown of key parts created an incredibly dangerous riding situation, leaving the scooter unridable, and the customer support received thus far has been disappointingly inadequate. The first three months of ownership were enjoyable, and after fixing an initial stem wobble with some Loctite, the KQi3 Max scores high marks for speed, acceleration, comfort, battery life, and design compared to other models in the price range. At the three-month mark of ownership, the throttle lever of my KQi3 Max became jammed in the 'on' position while riding. This malfunction resulted in an uncontrollable burst of acceleration that not only caused a minor accident, but it also shredded the rear tire — effectively rendering the scooter useless. Considering the high speeds this scooter is capable of, I consider myself lucky to have only sustained minor injuries. It could've ended significantly worse. Having faced problems with other brands in the past, I was aware that such issues can occur. What matters is how the company handles it. I promptly contacted NIU's support team to report this dangerous defect and was met with a sluggish, impersonal response. It took a week for them to finally get back to me with a ticket closure email, informing me that they are sending a replacement part for self-installation. My ticket ID, RMA BS230605-0002, apparently doesn't merit direct communication with a support team member or a conversation on an agreeable resolution. NIU's solution appears to be sending me an unidentified part with zero context or instructions for installation. Diagnosing the precise mechanical issue, determining the correct replacement part, and having the technical know-how to correctly install it should not be assumed as commonplace skills for all customers! Given the severity of the defect, a professional repair should at least have been initiated by NIU, or barring that, a complete unit replacement. The rear tire is connected to the motor, so it is possible not only the throttle but the propulsion system itself is compromised. There's a middling chance of me correctly identifying the severity of the issue and successfully fixing it myself, but the NIU team is just resorting to the cheapest and easiest option for them, not what will actually resolve the problem. How is an unidentified DIY part a good solution? It's disheartening and alarming how dismissive NIU has been regarding a defect that directly threatens user safety. In my extensive experience with electric scooters, I have never faced such a dangerous issue coupled with such a lackadaisical approach from the support team. In light of this, I cannot recommend the NIU KQi3 Max scooter or the company's support system. I will be happy to update my review if the support team is able to adequately address the mechanical issues, but at present, with numerous other reliable options available in the market, your safety and peace of mind deserve better.

This is hands down the best scooter for the price. The front suspension and air filled tires make the ride incredibly smooth especially compared to solid tires, which tend to amplify every bump and vibration. The handlebar is a bit long, but it folds down, which is great for storage. I added a phone mount, though, so now I can’t fold it anymore. It’s a trade-off I had to make, but I do wish the handlebar were shorter to make it easier to navigate tight spaces and add more accessories. Battery capacity is modest, but for my daily commute which is flat and not very long this scooter is my best ally. It helps me avoid traffic and get to my destination quickly. Plus, its folding design and lightweight build make it super easy to carry up to my apartment without breaking a sweat.
