NIU K100F/AIR Electric Scooter Adults - 600W-700W Peak Power, 18-30 Max Range, Top 17.4-20 MPH, Portable E Scooter w/Suspension for Commute, Sup. Turn Signal, Folding Handlebars(Only K100F)

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.

Have only had the scooter for a few weeks but I am super impressed with it so far. The performance is very similar to my Ninebot Max, with it just barely beating it in top speed and acceleration. My wife and I go on rides together with me on the Ninebot and her on the Niu, and we don't have to worry about one of us leaving the other behind because they perform so similarly. The ride quality however is much better on the KQi3 Pro. The deck is slightly wider, and I don't know if it's the tires or what, but the ride is much more comfortable and stable on the Niu. It makes me want to trade my Ninebot Max for another Niu. The build quality seems to be top notch. The Ninebot Max of course holds the crown for durability in eScooters, but it seems to me Niu has a very well put together scooter here. If it does end up being just as durable as the Ninebot, I think it will (or at least should) dethrone the Ninebot as the most recommend scooter for all-around use. The one thing I worry about that might prevent this from happening is the brakes. The Ninebot has a very simple but durable and effective system of a front drum brake and rear electronic braking. Nothing is exposed to the elements. The Niu has front and rear disc brakes. Of course so do motorcycles and most cars and that's not necessarily a problem. But disc brakes on eScooters can be a problem area IF they aren't high quality. Overall I am very impressed with the scooter, and with the price compared to a Ninebot Max, if it does have the durability of the Ninebot I can't see any reason why I wouldn't recommend the Niu KQi3 Pro over the Ninebot Max. Niu has been making electric mopeds for other markets around the world for a long time, so they already have a lot of experience making electric vehicles, so I don't see any reason to think that the Niu won't hold up.

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.

The KQi3 Max isn't perfect, but under $800, it can't be beat and does the basics well. The acceleration is good and it can take medium hills, unlike my entry-level M365. It's hard to modulate the throttle to gently accelerate or stay at slow speeds, but the regen is nicely tuned. The brakes are grabby, but once you get used to them, you can smoothly modulate them and stop very quickly. Shock absorption isn't great because there's no suspension, but that's hard to find at $750 and below. The weight is much higher than entry-level scooters, so it's harder to carry up stairs or sling over your shoulder. Battery life is excellent, with performance dropping a reasonable amount below 50% and the scooter still usable and capable of going above 15mph. Bonus features: I like the ability to "lock" the scooter so it can't be easily rolled away by a thief, which is nice for quick stops when a U-lock is inconvenient or difficult to affix. The headlight is bright but has a limited beam width/height. There's not too many firmware settings besides top speed, although zero start is available if you don't like kicking off. Be careful: it's easy to accidentally push the throttle and swing your scooter forward! Modding: There's no major firmware modding groups for NIU, but their firmware has most of the features you'd want. It's easy to replace the handlebar grips and add accessories since it's a standard 22mm diameter. There's a repair manual available online and it's easy to access the 48V wires and put small electronics behind the dashboard (I'm adding turn signals and a brighter headlight). Unfortunately, there's no kits to "drop in" front or rear suspension, so you'd have to do a lot of fabrication. Ditto for a rear cargo rack, which is inconvenient when you're getting groceries. The competition: Below $800, you might be able to find suspension or dual motors, but I couldn't find reputable scooters that do the basics as well as the KQi3. At $850+, the Ninebot Max G2 is an excellent scooter, but rarely goes on sale or is available refurbished. It also has merely adequate brakes and worse performance below 50%, so I don't regret skipping it (although I am jealous of the better accessory options).

Excellent scooter very smooth long battery life perfect for commuting around town lights for safe night riding excellent power and speed perfect for my 16 yr old, she was able to assemble it with no issues fairly easily.

I initially purchased Niu KQi 100F directly from their website (the black model) - it arrived with the bell broken off in the box and the styrofoam padding shattered. Upon plugging it in to charge, the battery was DOA and did not function. The customer service experience dealing with NIU directly was horrible. They refused to send me a replacement scooter until the first one was returned (initially they would not refund me despite me having purchased additional "worry-free" purchase protection). I returned the first scooter to NIU and purchased the same scooter through Amazon the second time (the grey model) and it arrived intact and functioning. Overall, I do enjoy the scooter, it feels sturdy and well-made, but the advertised range is nowhere near close in my experience. I live in a flat part of Orange County, right near Disneyland - and after about 10 days of testing, I've found that the scooter can just barely hit about 8 miles of real world range, which is less than 50% of the advertised range of "up to 18 miles". The Niu app is also super glitchy and doesn't actually record your rides. Overall, while I do feel that the scooter is decent and well made, I've had 2 scooters with issues from the same manufacturer in under 90 days, so I'm wondering if there are larger issues at play? While the scooter has a fantastic combination of features, the IP65 water resistance, the foldable handlebars, the turn signals, the front suspension - but the range... the range really hurts. I suppose this device truly is ideal for a "last mile" solution? I was really hoping for 10 miles, but I can just barely get 8.
