Segway Ninebot S2 Electric Self-balancing Scooter, 11.2mph Top Speed, 21.7 Miles Range w/Adjustable Height, Hoverboard UL-2271 2272 Certified

Before I bought this I had a hard time finding any reviews for the S-Max... So this is for those wanting info on this specifically for those with limited mobility.First and most importantly, I am disabled and have a hard time walking. I can't even grocery shop without use of a mobility scooter. I have been wanting something like this for several years but didn't want to get a regular hover board because of the balance and leg/back strength required. I read several reviews on the ones with the knee bar but was also scared of being too wobbly. The S-MAX is absolutely perfect for me. It literally took me about 5 minutes to feel comfortable on it. I haven't been able to walk further than 20 ft without stopping due to pain in about 5 years and yesterday after I received this, I rode it for 2 or 3 miles around my neighborhood. Today I rode it for 7-8 miles. After an hour on it yesterday, I could already open, go through, then shut my gate without stepping off, and my gate is in gravel. Also, since I have such back problems and in need of a hip replacement, I have been sitting more and more for years to the point that all the muscles in my back and legs have atrophied but I can still stand on this for hours after only one day. I wanted this so I could get out more easily and to re-strengthen my legs and back and it is working because I can feel the soreness in my muscles.I was worried about the "Tilt Back" that many have mentioned when you get up to the speed limit but after feeling it repeatedly, its not really bad at all due to having the steering wheel on which to hold. In fact, all of the concerns I had after reading so many reviews about the S Mini's and others with the knee bar have completely been eliminated due to having the bar and steering wheel to hold. I also spent some time in my yard because I wanted to test various terrains other than smooth pavement, and moving at walking speed is no problem forward, backward and turning on the uneven ground. I don't need this in my house but when I first turned it on, I drove it around everywhere I can walk, including a small bathroom. If the wheel width can fit, this can be ridden due to being able to turn in place and back up. The fastest speed (12.2 MPH) is a perfect speed for me, It's not too fast and yet I don't feel like I'm crawling around the block. There were several times my back started aching and I just leaned over onto the steering wheel, propping myself up with my arms, taking some of the weight off my legs and was still able to move around with no problems and effectively rest at walking speed.For anyone that is suffering with mobility problems but can stand in one place relatively easily I highly recommend getting the S-Max and trying it out for yourself. After only 2 days, I feel like I can go anywhere that one can walk and I'm already looking forward to going places like the zoo that I couldn't go for several years now. I know that I could have rented a mobility scooter but those take up a lot of room and owning one means having the ability to carry it in your vehicle and loading it in and out is a problem if you can't lift it. The S-Max is still a little heavy at 50 lbs but since it is so compact, I can lift it myself and carry it in the smallest of trunks or cargo areas. As I stated earlier, I have been about 8 miles around my neighborhood and haven't felt like I was going to fall off or get thrown a single time. The battery seems to be sufficient as it was still showing a 53% charge when I stopped riding for the night. I did take it out after dark and since it has so many lights, I wasn't worried about being visible to other drivers. The headlights are pretty bright but the problem is that they are mounted very low to the ground and only illuminate a narrow strip out to about 10 feet. The good thing is, since the steering wheel is stable, one can easily mount some LED lights and get a much brighter, wider and further view. Since Flash lights are so small and bright these days, I will probably mount a small light for night riding. I also tried driving it around today with my phone in my hands while still holding on to the steering wheel and didn't feel like I wasn't in full control. The little digital speedometer is also a nice addition, although it would be better if it could be switched to Imperial units. I also like that the accent lights are customizable and that they work like brake lights and blinkers automatically as you slow down, turn and stop. Another thing that I read a lot and seems to be the general consensus is that they put the solid slick tires on it in place of pneumatic tires with tread which would make for a smoother ride and less likely to slide when coming in to contact with a wet surface. in fact I can't even find air filled tires to purchase. There are "comfort" tires to purchase from Amazon that have some tread but they are still solid and are kind of expensive at $130. not knowing if they will be any better.In summation, I love it and wish I would have bought this a long time ago and if it lasts a decent amount of time, I would definitely purchase another should the need arise. If you are on the fence about getting one and your not sure if it would be too difficult to learn and ride, I would suggest getting it and at least trying because chances are you will find it much easier to ride than you think.UPDATE: After having this now for 6 months and having put 350 miles on it, there are a couple things I feel I should add.First, the "Comfort tires are a MUST. although they are still solid, they are 100% more comfortable and safer with the tread.Second, the little " Speedometer " is absolutely worthless. It can't be switched to MPH, so its always a little guessing game as to your exact speed. The batteries, even if brand new, only last an hour... Maybe! Every set of brand new batteries I have put into it still registers as dead immediately. So to ride it for 2 or 3 hours a day, requires 2 or 3 sets of new batteries. Also since it connects via Bluetooth, you cannot use your phone at the same time. So using a cell phone is the best choice anyway because not only does it show your speed in imperial or metric, it also shows the battery temperature, the distance you have ridden and distance left for the battery charge remaining, GPS if you want and all the settings such as the lights you want on or off and the color of them, the speed controls and limits and pretty much everything else one would want to monitor while riding.Lastly: The customer service is useless. The 1st day I had it, I was having problems connecting my phone via Bluetooth and called them. After 2 hours, the guy never said anything helpful, never resolved my issue and after 2 hours, he literally said "Okay, so I'm going to need to get off here for a little bit" and he hung up...that was it. Turns out, the problem was simple, my lack of understanding how to connect at first, and should have been resolved in under 1 minute, which it was, after I understood what I was doing wrong.The other time I spoke to them was regarding the digital speedometer and why it always showed dead batteries and only lasted an hour or less. The "Customer Service" (and I use that term very loosely) agent literally told me that, "That's just the way they are designed, and they just don't work well". She never offered to replace it, and in fact when I asked her to replace it, she gave me a list of things that I needed to do for that to happen, which was designed to make sure no-one would actually go through that to get a new one and I was left feeling like she blatantly said to me... Tough luck, you bought it, it's your problem!! And that is just for that one little thing, I hope I never have a problem with the actual unit or any of its fundamental components that are required for it to operate.

Decided to replace my ~6 year old MiniPro when these went on sale for prime day with a new S Max, mainly for the larger battery capacity and higher top speed. I tried the "steering wheel" it comes with and don't really care for it, I'm much more used to the knee bar, but fortunately it directly swaps with the MiniPro, they use the same red triangular quick-detach (unlike the S/S Plus which press-on and are a PITA to remove). You can easily switch in the app to tell it if you are using the handlebar, or knee bar.The battery is about 40% higher capacity (430 vs 310 WH), and this is definitely noticeable. As usual, Ninebot's range claims are complete BS (MiniPro was claimed to do 17 miles, actually 10-12). They claim "up to" 26 miles from the S-Max, I've found realistically it's more like 15-17, but that falls in line with about 40% more range from 40% more battery. However, the charger is the same one as my MiniPro from 6 years ago, same voltage and wattage. Meaning the S Max also takes about 40% longer to charge. If it's flat or nearly so, you're looking at about 3.5 hours for a full charge. Definitely would have liked to see a more powerful charger accompany the larger battery, however Ninebot doesn't even offer one. Note the 59.5 volts the charger is at corresponds to only a ~80% true charge based on cell voltage. This is done partially to extend battery life, and partially because it relies on regen for braking, so it leaves a little capacity open in case you live at the top of a hill it can still absorb energy even when "fully" charged. You can buy an aftermarket 63v charger (which will get you a "true" 100% charge and a couple extra miles of range), however you will quickly get an error if you go down a hill right off the charger, will lean back, stop, and throw an error on the app for over-voltage, so I can kind of see why their official charger leaves a little juice on the table so to speak.The motors are also much smoother, you really feel like just floating along. My old Minipro had a little vibration, particularly around top speed, or going up hills/braking when the motors were under load, the S Max is totally smooth. While the Minipro would considerably slow down when going up hills and it was pretty easy to get the "over torque" alarm, the S Max can go up pretty much any hill still at full speed. It has to be really steep (definitely over the 15* max recommended) for it to start slowing down.Ninebot has definitely improved the lean-back/speed limit alarm. Older segways this was extremely tedious, as it was super easy to accidentally hit the "speed limit", triggering an aggressive lean-back slowdown and annoying beeping (ended up fixing that with an aftermarket firmware). The S-Max will start to gradually/gently tilt back as you get close to the max speed, you kind of don't even really notice and feels much more natural. If you continue to lean hard against it, really fight it's roll back then the beeper will go off, but in normal riding, I find that rarely happens, while it was a constant annoyance with the MiniPro before I flashed it.One big miss is that it comes with the solid "drift" tires (really intended for the gokart), even when purchased on it's own and not bunded with the gokart accessory. These tires suck for use in self-balancing mode. They're rock hard and the ride is extremely harsh and jittery. You feel every crack, bump, pebble, or grain of sand you run over. Traction is also quite poor on wet or uneven surfaces. You can get the "Comfort" tires (still solid/air free), which have a tread similar to the aired tires on other segway models, and are a much softer rubber compound. They feel like an aired tire at around the max PSI. Still a bit stiff, but worlds better than the "drift" tires it comes with. I guess Ninebot thinks the gokart is so amazing that everyone's going to buy it so they ship it with tires expressly made for use with the gokart? You'd think if purchased as a bundle, then it would have the hard tires, but if purchased on it's own, would have tires appropriate for use on it's own. If you will be using your S-Max in self balancing, consider the $130 or so to buy a set of "Comfort" tires a must, day 1 change. Fortunately changing the tires is a breeze. 6 bolts, hubcap comes off, the tires just slip right off. No need to remove the fenders or pull the motor. Thumbs up for that, thumbs down it ships with objectively the wrong tires.The S-Max is also notably heavier than my older MiniPro, but I suppose that isn't surprising considering the larger battery and more powerful motors. It's not something you want to be carrying around for any length of time. Picking it up over some stairs or in/out of a trunk is no big deal, but in an area you can't ride, you'll want to leave it on and use the "trolley bar" with the kneebar, or in handlebar mode it has a "power assist" button that lets you just tow it around with almost no effort.Overall really happy with it, the only miss is having to swap the tires essentially right away, but was able to sell them quickly (apparently the gokart eats tires pretty quickly sliding around, so replacements are in demand) and recoup most of the cost of the comfort ones.

This device is fantastic! I have a mobility disability that prevents me from walking long distances, but I can stand, and the Segway Ninebot S2 has been a game-changer. It’s incredibly stable and agile, allowing me to navigate crowded spaces like malls effortlessly. I was able to browse stores, weave through crowds, and even use crowded elevators with ease. It weighs only 30 lbs and easily fits in the trunk of my car so it is not hard to take it with me everywhere.If you're in the USA and have a disability, the Americans with Disabilities Act (ADA) protects your right to use this in most public places where wheelchairs are allowed. Search for the regulations on Other Power-Driven Mobility Devices (OPDMDs) if you want to learn more. If you can stand but struggle with walking, this might be the perfect mobility solution for you!
