- One of the most feature rich electric kick scooters I've tested, solid folding design, bright LED headlight, horn and cruise control
- Clever physical and regenerative braking combination, you get the benefits of regen with the safety and immediacy of a skid-brake
- Extremely light weight at under 25 pounds, smooth variable speed throttle and regen levers that match and create a clean symmetrical cockpit, three versions available for increased range and power for more money
- Limited standing space on the deck, no kickstand, narrow handlebar that can feel jittery and loose at times, the grips can be difficult to fold and the entire unit can be a pain to unfold at times
Electric kick scooters can be a perfect mode of transportation for getting from your house to the bus station… or the train station to your place of work. They are usually smaller than electric bikes, more stable than electric skateboards and priced affordably. With the E-Twow you get a sharp looking, folding e-scooter in either white or black for ~$999. It’s available in three flavors including Eco, Master and Booster with 350 watts, 450 watts and 500 watts of power respectively (each progressive power increase also moves the top speed up by ~1 mph). I’ve reviewed several other kick scooters and found the E-Twow to be unique in having a headlight, weighing under 25 lbs and offering both regenerative braking as well as a friction skid-brake integrated into the rear fender. With a top speed of ~18 mph (for the Booster model) and max load of ~165 lbs it’s capable but clearly not for everyone… At ~135 lbs myself, I found the scooter to be zippy but somewhat jittery at higher speed due to the handle bar design, I’m not sure I’d want to carry a big heavy backpack along on this thing.
I love the dual suspension setup however because the solid-rubber tires aren’t super forgiving. The regenerative braking activated smoothly and actually stopped me in a short amount of time when fully engaged. One area that did feel a bit limiting was deck size. My shoe size is ~9.5 Men’s and my feet didn’t fit onto the deck without adjusting the back foot a lot. This happens on most other kick scooters I’ve tried but many of them do not have the friction brake at the rear so I’m able to rest my foot on top of the fender. The EcoReco M5 is a great example of this… with the E-Twow I couldn’t put my back foot on the fender comfortably for stabilization without accidentally activating the brake. This created a feeling of instability for me at times. I wanted to spread my legs out to improve balance as speed increased but it just wasn’t possible, as a result I kept my speed a bit lower… especially while filming. Thankfully, the trigger throttle offers variable speed control and even shifts in to cruise control if you maintain the same speed for five seconds. This reduces hand and finger fatigue. When folded, the unit gets pretty small and feels very stable to lift, though a bit front heavy.
Driving the E-Twow (which stands for Electric Two Wheels btw) is a front mounted gearless direct drive hub motor unit. For the Booster model shown here, the motor is rated at 500 watts. This can be confusing because many full sized electric bikes don’t offer motors rated this high, when you look at the torque rating things start to make more sense. This scooter offers 15 Nm of torque whereas full sized electric bikes tend to peak out at 40 Nm. Given the smaller wheel diameter of ~5 in the motor gets a big mechanical advantage over bicycle wheels which are often 26″. In short, the motor works great and should be very durable if you don’t completely submerge it in water. Note that the motor will not activate unless you kick the scooter yourself up to ~2 mph (or adjust the menu settings and disable this safety feature). The idea is that someone could accidentally bump the throttle and have the scooter takeoff when the rider is not ready. In short, the motor works well for powering the E-Twow and also doubles as an engine brake by using regen. Many other kick scooters put their motors in the back wheel but I didn’t notice much of an impact on steering or handing here, it’s not super heavy. The biggest consequence of motor orientation here is that the unit is front heavy and tips forward if you try to lift from the center (when folded). One final heads up here is that motor produces some cogging drag because the electromagnets inside repel when the unit is coasting or powered off… it’s not terrible but it does impact coasting and could be a real drag if you run out of juice before reaching your destination. Expect 15+ miles of range for heavy riders or those carrying large backpacks.
Unfortunately, I don’t know much about the battery on this electric kickscooter. It’s built right into the deck and designed to stay there. You can easily charge it using the power port at the base of the stem but I’m not sure about replacements and you probably cannot charge it separately. For this reason I recommend storing the unit inside. Keep your scooter topped off if you haven’t used it for a couple of months to avoid a full discharge. Extreme heat and cold can damage Lithium batteries and this one uses a Lithium Polymer pack. Based on other similar kick scooters I’ve researched and tried, my guess is that this one is running at 36 volts 7.7 amp hours. The website says that it has a capacity of 280 watt hours and given the larger motor sizes on this and other models a 36 volt setup just makes sense (but comment and correct me if you own this and have found otherwise). Note that another big differentiator between the Eco, Master and Booster is battery size with 190 Wh, 250 Wh and 280 Wh respectively… Larger size means extended range.
Operating the Etwow from KERS Technology is more interesting than most electric kick scooters. It’s designed to charge in ~2 hours using the included 3.5 Amp quick charger and from there, you just press the rubberized power button at the base of the display. The monochrome LCD screen is backlit and includes a light sensor to automatically engage. You get all of the standard readouts including speed and battery level as well as odometer, trip distance and a light icon. The headlight is a neat extra that very few scooters seem to include. I love the way it’s integrated and appreciate just how large and bright it is (you get 6 white LED’s!) there are three other buttons on the base of the display including a very annoying horn, light activator and the mode switch (odometer to trip distance). Even though you get lots of extra information and a more precise speedometer on this scooter it’s still easy to operate and doesn’t have to be confusing. You can simply turn it on, move the unit forward a bit and press the right throttle to get going. If you want to slow down, just use the left throttle to activate regen… simple. I like how organized it feels and the fact that the two throttles are symmetrical and both offer a smooth, spring actuated lever so you can ease into starts or stops. At full blast, this thing can start and stop surprisingly quickly. The only complaint I have about the cockpit is that the fold up handlebar and grips seem a bit loose and rattly. Once they are in the up position it can also be difficult to get them folded back down, look for the little rubber mound that faces you and is near the inside of both grips and press it hard then pull the grips out to fold down.
To date, this is one of my favorite kick scooter options… despite the limited deck space and handlebar issue. I just like the regen AND skid brake and the unit feels high quality. If you’re someone who needs to solve that “extra mile” problem and are looking for a light weight kickscooter that’s built better than the cheap kids ones, this could be a great choice. There are definitely areas where this could be improved and I’d like to know more about how the warranty works (or if there is one) but overall it feels like a professional product. I also really like the EcoReco scooters and appreciate the colored wheel accessories, bags and trailer option (which the E-Twow doesn’t seem to have). Given the friction brake I feel like the rear wheel could wear out more quickly and it would be nice to know how to get a replacement, it would also be nice to see more pricing information at the official website.
- Comfortable full suspension design reduces the jarring feel of cracks and bumps that many small-wheeled scooters and bicycles suffer from, the larger wheels also help to smooth out the ride
- I love the way the stem folds down parallel with the deck and actually clips onto the rear fender, it makes this unit feel sturdy when carrying by hand… and I love how light it is at just ~24.2 lbs compared with many others that are upwards of 35 lbs
- 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
- The LCD display has a built in light sensor that automatically turns on backlighting, this scooter has a six LED headlight that you can activate independently and adjust brightness with (most other kickscooters I’ve tested have no lights)
- 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
- I like the two color options (black or white), many other kick scooters only come in black but the white looks very nice
- Cables are mostly internally routed so they don’t look ugly or get snagged, the frame is custom built to be an electric scooter and has a nice built in charge port near the base of the stem (near the red folding lever)
- 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 as I did at first in the video
- Due to the smaller battery size, the E-Twow scooter may be permitted as carryon luggage for some flights, be sure to check the FAA guidelines which are subject to change
- 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)
- To fold down the handlebar you need to press in at two spots near the front inner part of the grip then pull out and swivel down… even when you know what you’re doing it can be difficult
- Once unfolded and set upright to the riding position locks and this works well but when it’s time to fold back I found the locking clip difficult to disengage
- 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
- This isn’t exactly a con but ETwow designed the system to not start unless it’s rolling ~2 mph so you have to kick forward manually to get the throttle activated
- 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
- It’s not clear whether this kick scooter comes with a warranty, it seems well made and the website is fairly informative but it would be nice to see a guarantee
- There aren’t any built in locking systems that I could fine, someone could turn on the unit or tamper with the lights while parked outside
- 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
