Segway Ninebot ES4 Electric Kick Scooter with External Battery, Lightweight and Foldable, Upgraded Motor Power, Dark Grey

The controller for this scooter has a known defect that I found out about after receiving mine, but is well documented online if you do a bit of digging. Going over 13mph and using either the motors regeneration or electric brake causes a resistor in the control board to short out and turn the scooter off. I've owned a few different e-scooters and ridden them all over Seattle as a last mile mode of transportation, while ridding this scooter down a small hill I hit the electric brake to slow down for a stop sign and the scooter shut down causing panic while I pressed on the back brake as hard as I could in order not to slam into the back of a car at the stop sign quickly approaching. It's only a matter of time before you will need to stop quickly while riding an e-scooter in the city whether someone steps off a curb without looking or a car pulls out in front of you, if the braking system fails in that moment it could be deadly. I highly recommend no one purchases this scooter either on amazon or from the company.

I've waited as long as I could to write this review because I wanted to see if I could approach it from a long term perspective. This scooter has worked great and been a great mode of transportation for me in Downtown Dallas. It folds up and fits under the train seat perfectly and stays completely out of the way of other passengers. I had no problems for the first nine months and everything worked amazingly. About 6 weeks ago, I got a Code 21 and I looked around online to see if there were ways to clear it. I ended up going to Segway's site and learned I had to reach out to their tech support group. Here's where some of the negative reviews came from. Yes, the only way to get in touch with tech support is by sending an email request. Yes, it took a long time to get a response. They work the requests in the order they are received. In the end, it took tech support 2 weeks to get bck to me with some solutions. So yeah, that was a bummer. HOWEVER... I got a response from tech support with ways to clear the code. The solutions did not work BUT, I emailed them back saying I was still having issues and they got back to me SAME DAY. So once the support ticket is being worked, they stay on top of it. When we decided the solutions did not work, I was transferred from tech support to Segway customer service and they we on the ball! I got an immediate response with a pre-paid shipping label to send it in for service (since it's still under warranty). They gave me a timeline as to how long it would take (12-16 days) and sent me an email as soon as it shipped. It took 14 days from the time I sent the scooter until the time I received it back. There was a memo of the issue and what was done to repair the scooter inside the box. So, the whole process from the time I had issues until it was fixed and back in my possession took about 4 weeks. Yes this would have been expedited without the tech support bottleneck, so that probably needs some fixing. However, this is not my only source of transportation, so it's not a deal breaker for me. If you expect to have someone get back to you right away, you might be disappointed, but they will get back to you. These scooters are crazy popular right so I'm sure there's a big demand for tech support. Summary, the scooter has lasted a lot longer than I expected based on the early reviews. I did have issues with it, but they were resolved eventually. I gave it 4 stars because of the lag time with tech support, however, the service ended up being top notch.

I did a lot of research before I bought a scooter and I wound up choosing this one Segway es4. I have tried many ride sharing scooters and this one is in a class of its own. I love apple products and their quality. That is what you will feel when you drive this scooter. You pay more then other Chinese ones but it’s worth every penny. I’m 240lbs and it rode 19mph continually. Totally recommend buying this even for the extra money

I bought this e-scooter a week ago after having throughly researched avaliable scooters in the price range from 350 to 800 dollars. What I liked about this scooter was its extended battery life and high max speed of roughly 19 MPH. I also wanted solid tires since some colleagues of mine own e-scooters with air tires which supposedly are a pain to fix one broken. The first 3 days after the delivery were a great experience, even though it didn't fully live up to its specs: the max speed was roughly 18 MPH, battery drained faster than expected, and the electric break is relatively weak. The latter is actually an important point to make - the electric break only will not suffice in case of emergency breaking, and the back break has to be used as well in that case. I would much rather prefer a disk break that can be toggled on the handlebar similar to Lime scooters. Also, the battery is oddly placed so that you cannot easily carry the folded scooter at the balance point with one hand, but rather you have to hold it with two hands at the same time, making it much less portable than, say, the ES2 model. I actually find it very misleading that tñon the 4th picture they depict an ES2 model to make it look easy to carry (you clearly see that there is no second battery mounted on the front). It is definitely not possible to carry the scooter with one hand like this. UPDATE: the main reason for the 1 star review is that after 2 days the scooter stopped working with an errorcode '21' flashing on the LED display (meaning there is a problem with the battery control board). This is embarrassing for a product like this and shouldn't happen, especially not after just 3 days. This casts doubts whether a replacement product might also suffer from early failure like this.
