The most common injuries were fractures, head injuries and soft-tissue injuries. For comparison, two-thirds of the hospitalizations and three-quarters of the deaths from bicycle accidents are from head injuries. Copyright © 2019 HealthDay. Most patients were discharged from the emergency department, but 15 were admitted to the hospital, including two with severe head injuries. Among all the patients, 5 percent had blood alcohol levels that showed they were intoxicated, the researchers found. Rivara thinks that the cities that allow these scooters and the companies that rent them should have some provisions to ensure that renters wear helmets. Most injuries were from falls (80 percent), collisions with objects (11 percent) or being struck by a car or object (9 percent). Most patients had scans of their arms or legs, and 8 percent had CT scans of the head, cervical spine, chest, abdomen and pelvis-an indication of serious injury. These scooters can travel relatively fast, some nearly 40 miles per hour, increasing the odds for an accident and injury, he explained. The report was published online Jan. 25 in JAMA Network Open. Although not many head injuries from electric scooters have been seen yet, as their use increases, more injuries are likely to follow, Rivara warned. But wearing a helmet can prevent a lot of serious injury. When it comes to 72v electric scooters, most people don’t wear helmets, he added. Among all the patients, 32 percent had fractures and 40 percent had head injuries, the findings showed. Dr. Frederick Rivara, a professor of pediatrics at the University of Washington in Seattle, wrote an editorial accompanying the study.
In two Southern California emergency departments, nearly 250 people were seen for injuries linked to electric scooters in a single year, researchers found. In addition, companies such as Bird, Lime and Skip have set up standup scooter rentals in many parts of the country, which has resulted in some controversy over regulations for these modes of transportation. In all, 228 patients were injured as riders and 21 as non-riders. These data are likely a conservative estimate because the researchers only included patients seen in emergency rooms. The companies offering these electric scooters are rapidly expanding in the United States and internationally. Injuries associated with these electric scooters are a new phenomenon, she noted. Nearly 11 percent of injured riders were under 18, and only about 4 percent wore helmets, the investigators found. For the study, Elmore and her colleagues used medical records from University of California, Los Angeles-affiliated hospital emergency departments to look at accidents associated with standup electric scooters over one year.

Ultra-performance scooters don’t get as good as the NAMI Burn-e – so there’s a lot to talk about here. A word of warning here – while a smart battery management system does offer protection from overheating, you’ll still want to avoid overcharging, where possible. In the absence of the extra charger, it’ll take 12 hours. The Viper also sports an eye-catching brief charge time. But before we get to all of that, it would be blasphemous not to begin with the reason why we’re here – the Viper’s headline-hogging, spotlight-stealing 100-mile range. For this reason, try to only leave the Viper plugged in as long as you need to – it’ll ensure your scooter lasts for many long rides to come. Enabled by a gutsy 72V 2520Wh 35Ah Panasonic battery, the Viper lays claim to a maximum distance that’s double that of the Wolf King, and over three times that offered by the Turboant X7 Pro – the scooter we began our long-range rankings with. With two chargers connected, the Burn-e takes just 6 hours to charge.
It’s also worth keeping an eye on the industry-leading interface to see temperature and power readouts that’ll help you monitor your scooter’s condition and prevent the motors from overheating. The Burn-e calculates your remaining mileage based on your ride data. On that topic, we should note that unlike similar scooters – which force you to rely on a voltmeter or battery bars to understand how much mileage you’ve got left – the Viper takes a more granular approach. This feature is a particularly rare one – the only other scooter to offer such an accurate readout of your remaining range is the Apollo Phantom, which we discussed earlier. Now, I’d normally love to use this space to compare and contrast the Viper’s range with its closest competitors in terms of price and weight. Here, however, it’s just not possible – for the simple reason that, when it comes to the Viper, there is no contest.
The Viper hits 15 mph 11% faster than the Wolf King and Wolf Warrior, and 29% quicker than the Dualtron Storm. So much so, that – as with the brakes of the Wolf King GT, which we discussed earlier – a light touch is required to stop safely. When it comes to tackling hills, the advertising is quiet on exactly how steep a slope the Viper can handle, although our tests show that it’s comfortable with inclines of up to 35 degrees. With all that speed and power at your fingertips, it’s easy to get swept up and carried off in a tide of adrenaline – so it’s lucky that the Viper’s brakes are up to the task. When we extend that out to 25 mph, those speeds stretch to 17%, 23%, and 19%, respectively – and that’s just a taste of what the Viper’s imperious acceleration rates have to offer. The NUTT hydraulic brakes, which come kitted out with 160mm discs, are sharp and incisive.
Similarly, the Viper’s range of stem turning motion is locked to prevent you from over-rotating the handlebars and taking a spill. And – unlike the Storm’s 45-step suspension – you won’t need a whole toolbox at your disposal to do so. Via a small circular red dial over each shock, you’ll be able to quickly and easily ratchet up or down the damping to fit the specific stipulations of the environment. Best in class – and superior to the shock absorptive capabilities of any other scooter we’ve tested – these 165mm hydraulic coil-shocks soak up anything you throw at them. Impressively, the Viper’s coil-shocks also come with a surprisingly intuitive rebound adjustment feature. Unlike several of the more sedate, commuter-oriented models on this list, the NAMI Burn-e is built to tackle all kinds of environments. Though the 11-inch pneumatic street tires it comes with are tailored to flatter, more compact surfaces, the Viper’s adjustable KKE suspension is far less picky.
As far as design and durability are concerned, the Viper receives full marks. But we’re running out of room on the page, and – let’s face it – that 100-mile range speaks for itself. Feature-wise, a four-digit password protects your scooter from theft, while an intelligently crafted rear tire hugger protects you from mud splattering up your back while riding. What’s more, the Viper comes with twin water resistance ratings – IP55 and IP66 – that safeguard its display, cabling, and controllers from the perils of dust, debris, puddles, and precipitation. Ultimately, we could wax lyrical about the Burn-e’s litany of strengths for long-range rides – including its cruise control, hidden USB port, and luscious LED setup – all day. Its innovative carbon fiber stem eschews the classic aluminum alloy makeup favored by the rest of the electric scooter industry, and an industry-leading interface outstrips the QS-S4 and EY3 displays of the chasing pack.
The closest its rivals get to the Viper’s high-powered range are the Dualtron X 2’s 93 miles, and the 80 miles of the aforementioned Dualtron Storm. Also fitted with a pair of exclusively designed 50Ah Sine Wave controllers, a ‘Turbo’ mode that pumps 12% more power into the motors, and best-in-class acceleration. Like its namesake, the Viper is tough, terrifying, and terrifically fast – when you see it coming, it’s already too late. With dual 1500W motors enabling a top speed of 60 mph, the Viper belongs to an exclusive cabal of ultra-performance scooters: a group that also includes the Wolf King GT, as well as Dualtron models such as the Storm, X 2, and Storm Limited. The only other contender is the Dualtron Storm Limited’s insane manufacturer-stated 137-mile capabilities – though, with a whopping 11500W of peak power output, realistic mileage is far less. All that said, to assume that the NAMI Burn-e’s century of mileage is its only pulling point would be a mistake.
Performance can be an important factor if you live in a hillier area, as that will require some high torque performance from your e-scooter that not all are capable of. This latest version has rectified some of its predecessor’s niggling issues that were reported. The design and performance pushed the boundaries in a sportier direction than what was typically the norm for similarly priced e-scooters. They are wide and low profile solid airless tires, but they are flexible. The first thing one notices is the wheels. If you push your thumb into it you will feel that it is not rock solid. An 84v electric scooter that even manages to look cool. The Wide Wheel Pro is the latest updated version of the very popular Wide Wheel. The most popular options on the lightweight e-scooter market are the ones who in one or other way, can cover those areas, and have a proven track record as well as satisfied customers. First released in 2018, the Wide Wheel set a benchmark in the e-scooter world.

Kick and go means you have to manually kick off and once your rolling you can begin to use the scooter and accelerate. Dual disc brakes also on offer. The Dual motor PRO version has all of the above, plus a higher top speed at 33 mph (53 kph), longer range with 40 miles (64 km), and brutal acceleration. 30 miles (48 km) of range. It weighs 50 lbs (22.6 kg), has the same brilliant dual suspension system as the Mantis 10, albeit 8 inch tubeless tires instead of 10, to make it a smaller version. A lot of scooter come with the option to turn off kick and go, which if you’re riding for fun is a sought after feature but starting from 0 does take a lot of power and drains the battery faster, which of course will reduce the over all range you get on a single charge. Two versions are available. Mantis 8 is a newcomer with a lot of promise. Advanced display and throttle combination allows for configuration of speed limit, cruise control, regen braking system.
