Fast Answer for Busy Riders ⚡ (TL;DR)
The Segway GT2 takes the overall win here thanks to its vastly superior ride comfort, stability, and overall refinement; it simply feels more sorted and confidence-inspiring at real-world speeds. The Dualtron Storm New EY4 hits harder on power and range, and its removable battery is a genuinely useful trick, but it feels more like a big, fast tool than a cohesive, polished vehicle.
If you're a long-distance torque addict with somewhere safe to park a hulking chassis and you like tinkering with settings and parts, the Storm New EY4 makes more sense. If you care more about how the scooter feels underneath you than how large the battery number is on a spec sheet, the GT2 is the smarter choice.
If you can, keep reading-these two look similar on paper but behave very differently once you're actually standing on them.
Hyper-scooters like the Dualtron Storm New EY4 and Segway GT2 are what happens when engineers get bored of rental scoots and decide to build something you probably shouldn't take on a cycle path. Both are heavy, brutally fast, and aimed at riders who think "last-mile" sounds cute but mildly insulting.
The Storm New EY4 is the classic hooligan: massive removable battery, brutal torque, industrial aesthetic, and the sort of presence that makes car drivers suddenly remember their insurance excess. The Segway GT2 is the techy grand tourer: less obsessed with sheer numbers, more about suspension geometry, traction control and a ridiculously pretty display that looks like it escaped from a concept car.
On the road, they feel like two different philosophies of "overkill". One is a blunt instrument with some smart upgrades; the other is an over-engineered spaceship with a slightly modest tank. Let's dig in and see which flavour of ridiculous makes more sense for you.
Who Are These For, and Why Compare Them?
Both scooters live in that awkward space between "high-end toy" and "genuinely might replace your second car". They cost serious money, weigh more than many mopeds, and will happily cruise at speeds where a fall means a hospital, not a plaster.
The Dualtron Storm New EY4 leans into the traditional hyper-scooter crowd: performance junkies, heavy riders, long-distance suburban commuters, and Dualtron faithful who like the idea of a removable 72V battery and a proven platform turned up to modern standards.
The Segway GT2 is pitched more at tech-savvy riders who value refinement and safety tech over sheer battery capacity: people with garages, decent roads, and a taste for plush suspension, traction control and a polished user experience.
They sit in a similar price band, take up similar amounts of hallway, and both promise "endgame scooter" status. That makes them natural rivals, even if they go about the problem very differently.
Design & Build Quality
Pick up the Storm New EY4 (or, more realistically, try to shift it an inch and swear quietly), and it feels like a chunk of industrial hardware. Thick, angular arms, exposed metal, RGB strips, a big boxy removable deck-battery: this is classic Dualtron-function first, aesthetics somewhere between "cyberpunk forklift" and "armoured street furniture".
The GT2, by contrast, is what happens when a consumer electronics giant is allowed to design a scooter without a bean-counter screaming in the background. The lines are cleaner, tolerances tighter, the finish more uniform. Welds are neater, panels line up properly, and the whole thing gives off "production vehicle" rather than "hot-rodded platform". The transparent PM-OLED dash and the integrated lighting make the cockpit feel like something designed, not just assembled.
In the hands, controls tell you a lot. The Storm's EY4 display is a big step up from the old Dualtron triggers, but there's still a faintly utilitarian vibe-buttons and plastics that get the job done but don't feel especially special. The GT2's switchgear and twist throttle feel closer to a small motorbike: more solid clicks, better tactile feedback, less of that "add-on box bolted to handlebars" sensation.
Structurally, both are stout. The Storm's new folding collar and widened bars are a marked improvement over older Dualtrons: less creak, less flex, fewer white-knuckle moments over 60 km/h. The GT2, though, is in another league for chassis stiffness; stem play simply isn't a thing here, and the double-wishbone front end looks and feels like it was designed by people who also work on proper vehicles.
If you like raw, exposed mechanical muscle, the Storm looks the part. If you want something that feels engineered to within an inch of its life, the GT2 is ahead.
Ride Comfort & Handling
This is where the two scooters stop being cousins and start being strangers.
The Storm New EY4 runs Dualtron's signature rubber cartridge suspension. It's adjustable and good for high-speed stability, but the basic character is firm. On smooth tarmac, it feels locked-in and sporty-great for sweepers and straight-line blasts. Hit broken urban pavement or a stretch of cobbles and the story changes; you feel more of the surface than you probably wanted to, and after a dozen kilometres of that, your knees start submitting formal complaints.
The GT2's suspension, on the other hand, is its party trick. The double-wishbone front plus trailing-arm rear with adjustable damping make it feel like a shrunken grand tourer. It doesn't dive under braking, it doesn't pogo when you correct your line mid-corner, and it soaks up nastiness in a way the Storm simply doesn't. After several kilometres of neglected European side streets, I still felt fresh on the GT2; doing the same loop on the Storm felt more like a workout.
Handling-wise, the Storm's wider bars are a big help compared with older Dualtrons-there's more leverage, less twitch, and high-speed wobble is mostly tamed. But the weight distribution and stiff suspension make it feel a bit "on rails": it wants a committed input to change direction. Confidence is high as long as the surface is good, but sudden mid-corner bumps keep you honest.
The GT2 feels heavier in a planted, reassuring way. Those wide self-healing tyres and the suspension geometry make it track through corners with an ease that almost feels unfair-like you're cheating physics slightly. Quick line corrections, emergency swerves, braking hard into a bend: all are calmer on the Segway. It's the scooter I'd rather be on when a car does something stupid in front of me.
Performance
Power delivery is where the Storm New EY4 bares its teeth. Its dual high-voltage motors hit like a sledgehammer, especially at higher charge. Stab the throttle too enthusiastically and the front end gets light, your weight shifts onto the rear kickplate and you suddenly remember your helmet strap. It keeps pulling hard well into speeds that demand proper kit and proper respect. Hill starts? It doesn't so much "climb" as erase gradients.
The flip side is that the classic Dualtron square-wave feel is still there. Even with the EY4's tuning options, low-speed modulation isn't silky. In tight traffic at walking pace, you're doing micro-squeezes on the trigger and thinking about it; get sloppy and it can feel jerky. Fun on a clear stretch, a bit fatiguing in dense city riding.
The GT2 is the more civilised animal, but don't confuse that with "slow". Its dual motors and Boost mode give a strong, satisfying shove that gets you to urban traffic speeds in a heartbeat, just with less drama. The acceleration curve is more progressive; it feels like a well-mapped motorcycle rather than a switch. You still absolutely have to hang on, but your brain isn't playing catch-up with sudden power spikes.
Top-end, the Storm will stretch its legs a bit further than the GT2 when fully unleashed, and it keeps its urgency at higher speeds thanks to that higher-voltage system. The GT2 tops out a notch lower, but crucially, it remains composed as it does so. Past "I really hope the police aren't watching" speeds, I simply trusted the Segway more.
Braking on both scooters is strong, but the feel differs. The Storm's hydraulic discs plus motor braking can haul you down aggressively, and once bedded in, the system is powerful. The lever feel is decent, though not outstanding. The GT2's stoppers feel better tuned out of the box: more progressive bite, easier one-finger control, and less tendency to unsettle the chassis. Between the two, I'd rather be panic-braking on the GT2, especially in less-than-perfect grip conditions.
Battery & Range
On paper, the Storm New EY4 has the clear advantage. Its big 72V battery with quality cells gives it a real-world range that genuinely supports long suburban commutes or extended weekend rides. Ride at sensible speeds with some restraint and you can do a morning blast, a lunch run and an evening loop without sweating over the remaining bars. Even when you ride like it owes you money, you still get a decent chunk of distance before limp-home mode.
The GT2 is more honest if you think in car terms: plenty for daily use, underwhelming if you try to treat it like a touring machine. At moderate speeds, it covers a typical round-trip commute without stress and leaves a buffer. Start living in Race mode, enjoying that lovely acceleration and high cruise, and the battery gauge falls faster than you'd like. Many owners end up mentally categorising it as a solid "city-and-suburbs" scooter rather than a distance monster.
Charging tells a similar story but with one twist. The Storm, with its included fast charger, can be refilled from low in roughly a working afternoon or overnight without drama. The removable battery means you can lug just the pack upstairs and leave the chassis parked-still heavy, but more realistic than deadlifting the whole vehicle. The GT2's battery is fixed; twin charging ports help, but unless you invest in and carry two chargers, you're in for a long wait from empty.
If you define value by watt-hours and distance, the Storm wins. If your riding is mostly sub-20 km hops with a charger at each end, the GT2's limitation is more psychological than practical-but it's there.
Portability & Practicality
Let's be blunt: neither of these scooters is "portable" in any sane sense. They are both multi-dozen-kilogram slabs of metal and battery that want ground-level parking, not shoulder carries.
The Storm New EY4 is the heavier of the two and it feels it. Maneuvering it through tight doorways or up a couple of steps is a slow, deliberate operation. The folding system is mechanically reassuring but not what you'd call quick, and once folded, it's still big. The saving grace is that removable deck battery: instead of hauling the whole beast up to a flat, you can leave the chassis chained up and only haul the pack. It's still no featherweight, but it's a lot more realistic than moving the entire scooter.
The GT2 is a shade lighter, but in everyday life that doesn't magically turn it into a commuter scooter. It's still a back-strain in waiting if you try to carry it solo for more than a moment, and its folded shape is long and wide. The fold is more about lowering its profile for storage or for sliding into a large car boot, not draining the battery on the Tube.
Day-to-day practicality favours the GT2 when you're actually riding: the twist throttle is intuitive, controls are nicely laid out, the traction control makes sketchy surfaces less scary, and the suspension smooths out the city's worst efforts. The Storm counters with that removable pack and better out-of-the-box lighting, but the harsher ride and more abrupt throttle make it feel more "special occasion" if your commute involves a lot of chaos and low-speed manoeuvres.
Safety
Both scooters bring serious hardware to the safety conversation, but they lean on different philosophies.
The Storm New EY4 focuses on brute-force safety: big hydraulic brakes, strong motor braking with ABS effect, extremely bright dual headlights that actually light the way, and vivid side and deck lighting that makes you look like a mobile arcade cabinet at night (in a good way). Wider bars and a stiffer stem have greatly improved high-speed stability versus older models. At speed on a dry, predictable surface, it feels substantially safer than many high-powered competitors.
The GT2 adds brains to the brawn. Its braking hardware is rock solid, but the extra layer is Segway's traction control. On wet asphalt, gravelly patches, autumn leaves-those sketchy in-between conditions where powerful scooters usually keep you tense-the GT2 calmly adjusts torque so wheelspin is less likely to catch you out. The chassis geometry and suspension also keep it far more composed under hard braking or mid-corner bumps.
Lighting on the GT2 is also excellent, with a strong, properly focused headlight and effective indicators. The self-sealing tyres add another small but real safety buffer: a nail or shard that would end your day on other scooters may barely warrant a shrug here.
In perfect conditions, both are safe enough for riders who respect their limits. In imperfect, real-world conditions-wet manhole covers, patchy tarmac, late-night rides-the GT2 gives you more electronic and mechanical backup when things get messy.

Price & Value
Looking purely at the sticker, the Storm New EY4 asks more than the GT2. In return, you get a bigger, higher-voltage battery, more headroom at the top end, and that removable pack. On a specs-per-euro basis-especially if your priority is range and raw output-the Storm looks like the more rational buy.
But value isn't just battery size. The GT2 costs less yet feels more premium in many small but important ways: cleaner assembly, fewer rattles, better suspension, better integration of electronics, and rider aids that genuinely help in the real world. You're paying less for polish and more for R&D-heavy components like the chassis geometry and traction control, rather than an oversized tank.
If you want the most watt-hours and torque for your money, the Storm edges it. If you want something that feels like a finished product, where you're less likely to endlessly tweak and more likely to just ride, the GT2's value proposition is stronger than its spec sheet suggests.
Service & Parts Availability
Dualtron has been around the enthusiast scene for long enough that getting parts is rarely a drama. From brake pads to swingarms, third-party and OEM suppliers are all over Europe, and the community has documented almost every repair you can imagine. The flip side is that some jobs-especially involving that heavy removable deck battery-are not exactly pleasant Saturday activities, and you'll occasionally be chasing creaks or checking clamps if you ride hard.
Segway, being a mass-market giant, has broad spare parts coverage and a dealer network that is better than most boutique brands. Basic wear parts are easy to source, and warranty processes are typically more structured. That said, some of the GT2's more exotic components-like the unique display or certain chassis elements-are less likely to have cheap third-party alternatives, and you're a bit more at the mercy of Segway's ecosystem.
For tinkerers and modders, the Storm is friendlier. For riders who'd prefer to treat the scooter more like an appliance and less like a project, the GT2 fits better.

Final Verdict - Which Should You Choose?
Choosing between these two is really choosing what kind of "too much" you want in your life.
If your priority is raw power, long-ish range, and the flexibility of a removable pack-maybe you live in an upstairs flat or plan proper long-distance blasts-the Dualtron Storm New EY4 makes sense. It's a proven platform pushed into the modern era with better cockpit tech and stability. You'll live with a harsher ride, a more demanding throttle, and a bit of ongoing mechanical babysitting, but you'll get muscle and endurance in return.
If, on the other hand, you care most about how the scooter feels from the moment you roll away-planted, smooth, confidence-inspiring-the Segway GT2 comes out ahead. Its suspension, traction control and general polish make it easier to ride fast without feeling like you're constantly one mistake away from a horror story. The range is only "good enough" rather than spectacular, but for most urban and suburban riders, that's actually fine.
Personally, if I had to live with one of these day in, day out, I'd pick the GT2. It's the scooter I trust more on bad roads, in bad weather, and at bad speeds. The Storm New EY4 is the one I'd take when I want to remind myself what overkill feels like-but I wouldn't pretend it's the more complete machine.
