Segway Ninebot Gokart Pro and Gokart Pro 2, Electric Go Kart with Enhanced Safety Features, High-Speed Racing and Immersive Gaming Combo, Ultimate Drift Experience for Ages 14+, Up to 15.5 Miles

My sons and I have had Segway S machines since Christmas and we've really enjoyed them. We considered getting the Go Kart kit for them but when I saw this I waited until Segway Ninebot released this to the pubic.The box it came in was all beat up, and some of the Styrofoam was broken, but the actual go kart was in perfect shape. It pretty much comes assembled fully. You just have to spend about 15 to 20 minutes putting the little pieces together and then plug it in for a full charge.I was skeptical about how well this is built until I got it. This thing is SOLID! The pedals are well-made, the frame feels very sturdy, steering assembly is solid, the speaker is a nice piece of equipment, the handbrake works incredibly well and I never feel any instability at any speed. A couple of people have ridden this that well-exceed 220 lbs and they were able to achieve the top speed. I did buy a compatible speedometer from eBay which costs like $40 to $50 at the time. Not sure what it is now. That is my only real complaint. They should have included a speedometer.So, all I have to say is WOW! This is nothing but pure fun. The acceleration is phenomenal. Much better than the standard gas combustion go karts you use on fun park tracks. It really puts you back in your seat like you are driving a Lamborghini (which I have driven) but it tops out at 23 mph. So basically you are at full speed in about 1 to 1.5 seconds.This thing is VERY low to the ground, but you do have enough clearance to avoid smashing the front on most entryways to driveways and sidewalks. You need to be really careful and use the flag it comes with. Cars are going to have a very hard time seeing you around any objects. I would be very apprehensive letting any child drive this on any public road in any neighborhood because of that reason alone. Try not to be too cool for helmets and extra pads for your knees and elbows. You never know when you have to make a really sharp emergency turn to avoid something and flip this over even though it would be hard to do (it is possible though).Because you're so low, and obviously you are wide open to the outside, the 23 mph top speed is going to feel much faster than 23 mph in a car. That is what Space Mountain and Thunder Mountain at Disney World achieves for speed even though it seems much faster. This will satisfy a lot of thrill seekers.The steering is pretty sweet once you get used to it. At first it seems very jerky but it isn't meant to be precise at slow speeds without power steering. After a while you'll realize that it performs nicely at high speeds and rounding corners at high speeds is great once you get the hang of it. I have NOT been able to drift in this go kart because the roads in my neighborhood need to be paved. It's impossible to drift. I need to find a place where the surface is smooth enough and then I'll report back on it.The speaker really is a neat aspect of this. It is rechargeable but one thing to note is that it does take a while to recharge. It synchronizes with the pedals so that when you push the gas it revs up like a race engine. It is done almost perfectly. As you accelerate the sound becomes far-more aggressive. Not using this leaves you with a silent ride which isn't nearly as much fun. You can also synch your iPhone to it and play your music instead, but I'd rather use the engine sounds. The only thing I didn't like about it is that it did not come with English instructions. Just Chinese - I don't know if that is something they forgot to put in there, or they just counted on people figuring it out. It wasn't hard and the Segway app picked it up right away.The lighting effects are cool but the green headlight on this is basically useless in terms of illuminating what is in front of you. I imagine they did not put real headlights on this because they don't want people driving at night in this. I imagine you can find external, battery operated lights to mount on both sides if you wanted to. I might try that down the road, but for now I'll keep the night rides to a minimum.This comes with a knee-bar if you want to take the Ninebot S-Max out of it and use it like the Segway S models (hoverboard style). It's better than what comes with the S, but it does not come with the full extension bar that you steer with your hands like purchasing the Ninebot S-Max separately gives you. I imagine that Ninebot will eventually offer this as an accessory but as of today they do not.This was a impulse purchase, but it is so much fun. The only issue is that there aren't many places around to ride it. Even in my neighborhood, people park on the side of the road during the day and it gets hard to see cars coming. We're going to find other places to take this to. This is a no-brainer if you're looking for something really fun and aren't worried about the cost.

Like someone mentioned above, you need the MiniPro for this. It wasn't super clear to me when I ordered it (the hazards of online shopping), so I had to order the minipro once I found out. The first Segway showed up DOA, so I'll review the kart when it's working.UPDATE 1/6/2018: The second Segway arrived with power, unlike the first one. The instructions for the kart assembly are over-complicated and somewhat confusing. I'm convinced that 90% of manufacturers never give their products and instructions to someone who's never seen either before, so they can watch the process unfold right before them, then go and fix their lousy instructions. The irony is that IKEA instructions is all they needed here, but you get a lot more than that.In any case, here are a few tips.1. Update the firmware on your app. Even if you already did, check it again. I thought my firmware was up to date since I'd just updated it a couple days earlier, but something about the Segway being attached to the Kart or them being in the same room together makes more updates available. And even when you think you're done updating, you probably aren't.After I assembled the kart and powered up, the app showed the Segway instead of the Kart, and it told me there was a firmware update. I updated the app and figured we were done with updates. But we weren't. After assembling the Kart and powering it up the first time, the red light on the steering column was flashing and loud beeps were going off, five short ones and seven long ones, and there was no power to the accelerator. This is not good. To make a long story short, I detached the Segway and removed it from the Kart, checked the firmware for the Segway itself, and sure enough, there were three new updates. After running those, the red light and beeps went away and we had power.2. Assembly goes like this.Remove the steering mechanism from the Segway. There's a quick release at the bottom. Just undo the quick release and pull the steering bar off. Then remove the red steering bar holder by removing the two hex screws. It's pretty snug so you might have to wiggle it a bit. The Kart came with a box complete with brackets, screws, one wrench and this odd little metal part with two prongs that came with the kart DON'T GO ANYWHERE ON IT. They are actually only used if you can't pull the Segway steering bar holder off. You create this makeshift removal tool with them. I missed that part of the instructions and sat there wondering for a while why I had all these extra parts.The screws for the seat extension are already in the extension bars and they can't come out. The screws in the box are only for the extraction tool you probably won't need.There is a plastic part that goes over the top of the Segway base, strapped under the kart. Unstrap the straps and put the plastic piece the only way it can go on the Segway base.Put the base under the Kart with the power button facing you. Here's the real fun part. The two power cords are just long enough to find each other and attach. They attach on the outside of the power cover, not behind it. If you use reading glasses, you're going to need them. Take a couple breaths then try your best to line up the power cords. If either one was about an 1/8 of an inch longer, this would be easy. But they're not and so you'll feel like you're going to pull one of the cords out in the process. The fact that you have to repeatedly separate these in order to charge the Segway or remove it is a concern. They are not going to last.Adjust the steering column and the seat. The seat is easy. The four screws I mentioned that are already in the adjusting bars just need to line up with the position holes (tighten these down good. After our trial runs, they were all loose).The steering column is odd. The Kart comes with a quick release but it's not what you think, it's not like a quick release on a bike seat or scooter handle where you pop the release bar, move whatever it was holding, then lock it back down. It doesn't release anything, it just makes it easier to tighten the nut that holds the steering column in position. When you want to adjust the steering column for someone taller or shorter, you have to remove the entire "quick" release, move the column, then put the release screw and latch back in. And they are not willing participants in the process.Put your reading glasses back on, then open the battery compartment on the steering column. Look closely... the images of the battery are white and, you guessed it, so is the plastic holder. They're hard to see at first, but they indicate which direction the batteries on the bottom and top go.Push the power button, connect your app, then follow the training instructions. If you get the red light and beeps, see above re the firmware. The training is basically going forward once, then backward and you're done. Take it outside and run it at the lower or middle speed. You'll need to have your phone with you for two reasons. First, after you go something like 1,000 meters, you can enable the top speed on the app. You have to be stopped completely to do this. The other reason you'll need your phone is because, after taking this thing for a good spin, you're going to want to order another one.

I had been looking at purchasing this product for over a year. Finally decided to go ahead and purchased it mainly because Amazon had it in stock. Upon arrival the box was very neat and perfectly packaged. Assembly was not difficult but also not easy. Instructions are kind of hard to understand but you can find many videos online. After setting up the Go kart and calibrating with blue tooth after a full charge we decided to try it out. This product was SO MUCH FUN! I cannot say how much fun my family and I had for 1 day. The next day after a full charge we decided to pull it out I was personally driving the go kart going over 20 mph all of a sudden I had a beeping noise that I never was able to get to go away (not battery related) its programming related and I pretty much lost any brakes. Luckily we were in our neighborhood and not in an intersection or anything like that and I was able to coast to a stop. I had to get out turn off and turn on and the Go Kart would work find for 10 mins, then the same issue would happen. Finally after a few tries the beeping and red light would not go away. I tried youtube videos, Amazon Support, Segway support which is a real problem. They are only open M-F certain hours. Most of the time they have long wait times. I decided to return this after researching online that this is a common problem. Great fun for 1 day, kinda dangerous when you lose Braking. Buyer beware.
