  • Very light weight at just ~24 lbs, integrated LED lights improve safety and convenience (I love that the headlight is mounted up high in the stem), offers regenerative braking as well as friction braking with the rear fender, cruise control saves finger muscles but activates automatically which can be confusing
  • The deck isn't especially long and you can't rest your rear foot on the back fender because it swivels up and down for braking, regenerative brakes can kick in a bit abruptly
  • Beautiful backlit display panel, available in several fun and professional colors, clean integrated wiring, light weight portable charger but the charging port can be difficult to reach when folded
  • No kickstand, difficult to fold, short wobbly handle bar can unstable and is a bit tricky to fold, front suspension offers minimal travel if at all, solid tires won't go flat but aren't as comfortable

Written Review

In 2016 The Uscooters Booster emerged… confidently taking replacing what was formerly called the E-TWOW Booster. In short, these two scooters are very, very similar with major differences being the addition of a rear LED light on newer ETWOW models and the Uscooter along with a slightly larger battery. This is one of the lightest weight, most exciting (at least on paper), electric kick scooters I’ve covered and that’s because it’s priced well, comes in a range of fun and professional colors, offers regenerative braking as well as friction braking with the rear fender, included integrated LED Lights that run off the main battery, uses air-free tires that won’t get flat and delivers front and rear suspension to compensate for those harder tires and thus, smooth out the ride.

In reality, my lofty hopes had to be adjusted because the front suspension offers very little travel, the folding mechanism was difficult to use, the deck space was very short and that made it hard to balance (moreso because the rear fender is a brake) and the throttle and regen came on abruptly vs. smoothly. The handle bars aren’t especially long and tend to jiggle when riding which makes for an unstable ride and I really, really miss having a kickstand. One redeeming quality is that the rear suspension works quite well. I also like that they included a cruise control feature to give your hand a rest from pushing the trigger but was confused about how it worked at first… it automatically activates when you hold the throttle for more than five seconds then you have to press the brake in order to de-activate it. I’m more used to coasting to a stop and pressing a button for cruise control so this was a bit unnerving at first. I’m not into rattly, unstable rides but it might be worth trading for with the Uscooters Booster because of how light weight and durable it is. The stem slides up and down with two locking points for tall or short riders and then it’s folded down for transport, locks in nicely with a clip on the fender.

I can’t help but be impressed with the utility of this electric kick scooter. I want to like it and could easily justify buying one for a shorter commute, ideally on mostly smooth roads, but compared with some of the air-filled tire scooters out there and those with even larger diameter wheels the Booster just wasn’t as comfortable. And while I like the idea of regenerative braking, I really prefer mechanical brakes for how smoothly they operate… they’re just more predictable and that can be a huge deal when commuting in crowds or near traffic. With a top speed of roughly 18 mph it’s nice that they incorporated a horn but I dislike the loud beeping when changing menus in the display. For someone with smaller feet, good balance and a desire for light weight short-range mobility this could be a great option, especially with the lights! but I’d suggest trying and comparing it to some of the other scooters if comfort and stability are important. You could always add lights to your helmet or backpack and yes, they’d be less convenient, but if the scooter feels more stable and you’ve got more room for your feet perhaps you’ll also be riding more safely and be able to ride more defensively.


  • Large diameter 8″ wheels reduce the impact of cracks and potholes, the airless tires are tough but not as comfortable as air so it’s nice that there’s a rear suspension point (the front suspension doesn’t offer much travel)
  • I love that the Uscooters Booster electric kick scooter comes in so many colors including bright green and white for maximum visibility, the gray and black are professional
  • You get two integrated LED lights that run off of the main battery and seem solid… seamless integration in the rear fender and front stem/control box, I love that the headlight has six LED’s and that it’s mounted high vs. low so cars can see you more easily
  • This is one of the lightest electric kick scooters I’ve tested which makes it easier to lift onto busses, trains or put into cars, the bars are also narrow so it fits through tight spaces easier (but might not feel as stable at times)
  • The lock point on the rear fender (to keep the scooter folded) is very clever and feels solid, just push down on the rear fender to release it
  • This is basically the same exact scooter formerly known as the E-Twow Booster but it has the rear light built in, I like the new Uscooters name better, the old name was pronounced E-Two-W and that flustered me
  • If you use the trigger throttle on the left you slow down with regen but you can also use the rear friction brake by pushing down on the back fender for a physical stop (important if the system goes out or something), the rear brake also initiates regen automatically
  • Built in cruise control function helps to reduce finger strain, just keep the E-Twow going the same speed for five seconds and it automatically engages, brake to disengage
  • Adjustable telescoping stem has two click-in points making the scooter easy to handle for short or tall individuals, it feels pretty sturdy and locks even if you forget to tighten the quick release collar
  • Unique front-mounted hub motor vs. rear may help to reduce cable lengths and cost/weight while improving durability by not folding cables regularly, for me the front-motor didn’t impact steering but did make it front-heavy when lifting in folded position, the steering rotation is also limited to avoid stretching cables
  • The display has a few extra neat readouts including ambient temperature and battery percentage in addition to an info-graphic of a battery cell, you can hold the S and Power buttons to enter a menu and switch from mph to kph and switch lights to automatic or manual
  • Built in cruise control to reduce hand and finger fatigue… just hold the throttle constantly for five seconds to engage then use either brake (fender or left trigger) to disengage


  • The front suspension really doesn’t work, I jumped up and down on the scooter and even had Sam push down on the bars and it didn’t seem to move (he weighs ~260 lbs so I expected some movement), the rear suspension does work however and feels good
  • The handle bar isn’t especially wide and the folding action feels kind of sloppy or rattly when riding but the two locking points for the stem make the bar feel secure from a vertical perspective
  • At higher speeds the narrow handlebar and jittery grips can be a bit unnerving, it’s nice to have extra power and speed but a longer deck would also make me feel more at ease (as an adult 5’9″ individual with 9.5 shoe size)
  • To fold down the handlebar you need to push in on these two little rubberized bumps then pull out and fold which can be a little tricky at first
  • The regeneration kicks in abruptly both with the left trigger and when using the skid brake… I like that they offer a friction skid design just in case the battery is completely full and regen won’t work
  • This is not an especially easy kick scooter to fold and unfold because the lever near the front of the deck is small and you have to almost pull forward on the bars while pushing down on the lever to get it to unclick (I put my left foot in front of the tire and push forward on the bars to tip the unit forward in a reverse-wheelie then use my right foot to push down on the lever)… it’s a bit of a balancing act
  • When folded, the charging port near the base of the stem is tricky to reach because it’s facing down towards the deck, many other kick scooters have the port mounted on the side of the stem or deck, thankfully the charger is pretty fast and portable, it would be easier to charge if there were a kickstand but folding half-way sort of stabilizes the scooter
  • No kickstand on this scooter, I found myself leaning it against walls (hoping it wouldn’t fall) or just laying it down on the ground and sometimes just half-folding it but this isn’t as easy as some other scooters
  • The horn is a neat idea but it makes a very unpleasant noise for the rider, I also felt annoyed with the loud chirping sounds that fire each time you press one of the display buttons… some other tone would be nicer
  • There aren’t any built in locking systems that I could find, someone could turn on the unit or tamper with the lights while parked outside but I guess that’s the idea of bringing it in with you thanks to the compact size and light weight
  • The gearless direct drive motor does not freewheel which means that you’ll have some resistance when not powering the unit due to cogging, most electric kick scooters I’ve tested suffer from this and it’s not a huge deal

I have 2 ETWOWs, Eco and Booster (same thing). These have no rear light, which I would love. They are SUPER quiet and quick. I love regenerative braking, with plenty of power for commuting and joyriding, but it’s unsafe to have no convenient, immediate, friction brake (the rear fender is difficult to remember and activate, and not intuitive in an emergency). I’d like bigger rubber wheels with built-in shock absorption, so bumps don’t vibrate the machine to death. The Eco was $600 from in China, but had manufacturing defects, so took an extended fight with Visa and AliExpress to get a refund.

I’m with you on the braking, I prefer a smooth steady mechanical brake vs. the regen thing… especially on the rear friction fender. I think I’d prefer it be just friction. Congrats on your refund win, I haven’t bought from AliExpress but it’s amazing what you can find there. Did the shipping take long and do you feel it’s basically the same product as what E-TWOW and Uscooters are selling here? Like is it exact just not with the same paint/stickers/branding?

The nut holding up the front suspension unscrewed, so now it’s a nightmare finding a bike shop or anyone to fix it near DC. Even from an authorized dealer, repair would probably be a pain. Let me know if anyone knows who can fix it.

Court Rye, yes, both regen and mechanical with a smooth, seamless transition would be best. On the lowest price, shipping took too long, and they played games with upgrading because of “low stock”, so I cancelled. The second lowest price (with good reviews) took maybe two weeks, and was EXACTLY the same, even stickers and branding, straight from the China factories. Unfortunately, the throttle (accelerator) lever was installed in reverse, with no spring mechanism. It works great, but always in cruise control, and not as safe. The seller got very angry, and accused me of cheating and lying when I requested a partial refund. Eventually, Visa gave me a full refund.

Interesting… sounds like a bit of extra time and screwing around but glad you got your refund and haven’t had any crashes with the throttle/cruise issue. Appreciate the background :)

My friends each bought a couple from aliExpress in China direct and both had nightmares. Don’t do business with them, one of them didn’t even get the Booster model he ordered and the other had no battery which is one of the most expensive items. It takes weeks to get the money back if you even get it back at all and Uscooters USA will not warranty or work on any scooters not bought from authorized dealers in the United States so your kind of on your own to go back to where you bought it. I bought mine directly of the Uscooters website and the minor problem I had was resolved by their service department right away. It’s worth it to pay a little more to know what your getting and to have support.

So sorry to hear about your friend… I’m with you on buying from dealers or “official” sources in the US. aliExpress seems neat but the time and risk often outweighs the money saved :/

I have tried it out yesterday, from a rental place here in Timisoara ( Romania ). I like to go to these places because I see how the scooters behave over time with heavy usage. I think the design choice of the rear suspension has some drawbacks. If you are heavier you push the back of the scooter more down and the handle bars will travel more to the back, and since the deck is not so long you might have to ride in an uncomfortable position, where your shoulders are behind your feet. I would get rid of the rear suspension and put an inflatable tire for the rear wheel. From other perspectives the ride was fun. ( even if the current consumption was limited and max speed was 19 Km/h )

Great points about how the suspension could sag and the handlebar position would change as you hit bumps… excellent feedback, thanks for chiming in Peter!

I bought an E-Twow last fall and it’s been absolutely essential in my life ever since. I live in the Bay Area and ride BART every day to work and the compactness and weight of the scooter makes it so nobody even notices that I have it with me, especially compared to when people bring their bikes on to packed peak hour trains and everybody is inconvenienced. I’ve put about 600 miles on it in a year and it still runs great and haven’t had any problems with it. I will probably buy a UScooter when I’m up to two years on my Etwow. Like any electric product the battery probably doesn’t hold as much of a charge as when it was brand new but that is expected like any other battery powered product. Overall I’m very happy with the Etwow/UScooter and recommend it to anybody that asks me about it. A lot of people have asked me about it over the last year, and I see others with e-scooters on trains and near where I work in downtown Oakland. I think e-scooters will become a big market over the next decade. Exciting times in electric mobility.

Thanks for the testimonial Paul! I used to ride BART to work in SF when I lived there and would have loved something like this. Hope it continues working for you for many years or that you find a worthy replacement when you decide to switch :)
