Dualtron Storm New EY4 vs Segway GT2 - Two Hyper Scooters Walk Into a City...

Fast Answer for Busy Riders ⚡ (TL;DR)

If I had to ride one of these every day, I'd go with the Segway SuperScooter GT2. Its calmer, more polished power delivery, excellent suspension and traction control make it easier to live with, even if it's not the wildest spec-sheet warrior in the room.

The Dualtron Storm New EY4 fights back with more brutal power, a bigger battery and that rare removable pack, making it better for long-distance, heavier riders and garage-less owners who need to charge upstairs. But you pay for that with a harsher ride and a more demanding personality.

In short: GT2 for "fast but civilised", Storm EY4 for "range and raw shove above all else".

Stick around - the devil, as always, is in the riding, not in the brochure.

Hyper scooters used to be cobbled-together torque monsters: fast, slightly terrifying, and about as refined as a brick with a throttle. The Dualtron Storm New EY4 and Segway SuperScooter GT2 are both attempts to civilise that chaos - without completely neutering the fun.

I've put real kilometres on both, from grimy city routes with broken tarmac to long suburban blasts where you spend far too long at speeds that would make your mum nervous. They live in the same rough price bracket, promise "car replacement" performance, and both claim to be the scooter you buy when you're done pretending a commuter toy is enough.

On paper, they're rivals. On the road, they have very different personalities - one is a refined techno-GT, the other is a slightly old-school brute dressed up with modern gadgets. Let's unpack which one actually suits your life.

Who Are These For, and Why Compare Them?

Both the Storm New EY4 and GT2 sit in that upper echelon where you stop calling it "last-mile transport" and start calling it "my other vehicle". Prices land firmly in the premium segment; neither is a bargain, both demand commitment.

They're aimed at experienced riders who want real speed, serious brakes, and the ability to keep up with traffic comfortably - not people popping to the bakery on rental scooters. Both handle heavier riders well, both are too heavy to be truly portable, and both can cover commutes that would be ridiculous on smaller scooters.

You'd cross-shop them because:

• You want dual motors and "this-could-replace-my-car" performance
• You have somewhere sensible to park and charge a 50+ kg machine
• You want something properly engineered, not an AliExpress science experiment

Design & Build Quality

Side by side, these two could not be more different philosophically.

The Dualtron Storm New EY4 sticks to the classic Minimotors script: chunky industrial frame, exposed metal, visible bolts, RGB everywhere. It looks like a military crate someone accidentally fitted wheels to. The removable deck-battery gives it that "modular machine" vibe, and the new EY4 display finally drags the cockpit out of the previous decade. In the hands, the frame feels solid and overbuilt, but you're always aware you're dealing with a lot of very real metal and not much subtlety.

The Segway GT2, on the other hand, feels like it was penned by someone who actually owns CAD software and a design degree. The double-wishbone front, sculpted arms, clean cable routing and that floating transparent display make it feel far more integrated. Plastics feel higher-grade, tolerances tighter, and there's less visual clutter. Where the Dualtron looks like an upgraded platform, the GT2 feels like a ground-up vehicle.

In terms of outright robustness, both are built like tanks. But the GT2 hides its tank-ness behind slick bodywork; the Storm wears it proudly on its sleeve. If you like your scooter to look like a machine, Storm. If you prefer something that feels closer to a futuristic motorcycle, GT2 takes it.

Ride Comfort & Handling

This is one of the biggest real-world separators.

The Storm New EY4 uses Dualtron's familiar rubber cartridge suspension. It's adjustable, but fundamentally it's on the firmer, sportier side. On good tarmac at speed, it feels very planted and predictable; your inputs translate crisply, and there's little wallow. Take it onto broken city streets, though, and the scooter stops pretending it's here to cuddle you. After a few kilometres of patched asphalt or cobbles, your knees and ankles will know exactly what they've ridden.

The Segway GT2 is noticeably more grown-up here. The double-wishbone front and trailing-arm rear, both with adjustable hydraulic shocks, soak up everyday nastiness much better. You can dial it soft enough to glide over urban scars without feeling disconnected, or firm it up for fast runs. It corners flatter than you'd expect, and on twisty descents it feels composed in a way that's rare for stand-up scooters. After the same bumpy city stretch where the Storm has you bracing, the GT2 leaves you thinking "That was fine, actually."

Handlebar feel: the Storm's wide bar is a huge improvement over old Dualtrons and gives decent leverage, but the overall character is still a bit "hyper scooter on a stick". The GT2's cockpit is more cohesive, and the chassis geometry plus that front suspension design make steering calmer at high speed. When things get sketchy - off-camber surfaces, surprise potholes mid-corner - the GT2 recovers more gracefully. The Storm can do it, but it asks more of the rider.

Performance

Both of these will embarrass cars from the lights. How they do it feels very different.

The Dualtron Storm New EY4 is the more violent one. That huge 72 V system and towering peak output hit hard when you ask for it. Off the line, it can feel like it's trying to tug the deck out from under your feet if you're not braced on the rear footrest. Mid-range pull is relentless; overtakes are just a twist away, and steep hills barely register as a suggestion. It's the scooter that always has "more" if you open it up, and the top-end is well into the "this belongs on private land" territory.

The problem - or charm, depending on your taste - is delivery. The Storm uses more old-school controller logic: the power comes in aggressively. You can tame it through the EY4 settings, but even then, low-speed modulation takes a deliberate hand. At high speed, it's exciting; in tight urban traffic at walking pace, it can feel a bit too eager.

The Segway GT2 has less peak output on paper, and you do feel that in outright shove compared with the Storm's "sledgehammer in the back" acceleration. But the sine-wave controllers and traction control make the power feel far more civilised. It still launches hard enough to startle new riders - especially in Boost mode - but the ramp-up is smoother, and traction control quietly saves your skin on dust, wet paint and gravel. Top speed is lower than the Storm's, yet still deep into "this is enough, actually" territory for real roads.

Hill climbing? The Storm just destroys gradients - you almost have to go looking for hills it notices. The GT2 is no slouch and will take on steep urban climbs without drama, but the Storm has the extra margin when you stack weight, incline and sustained throttle together.

Braking is strong on both, with hydraulic systems front and rear. The Storm backs that up with strong motor braking and configurable electronic assistance, which helps on long descents and saves pads. The GT2 favours a more car-like feel: mostly mechanical braking with linear levers and predictable bite. Stopping distances on both are confidence-inspiring; the Segway feels more progressive, the Dualtron feels more intense.

Battery & Range

The battery story is fairly simple: the Dualtron brings a bigger tank; the Segway brings "good enough" for most people.

The Storm New EY4's high-voltage, high-capacity pack is serious business. In sane mixed riding - staying roughly with city traffic, not drag-racing every light - you can get long rides that most commuters will never fully use in a day. Even if you ride it like it owes you money, you still have respectable distance before you're hunting for an outlet. And because the battery is removable, you can theoretically buy a spare and double your effective range, if your back and your wallet are both strong.

The GT2's battery is smaller, and you feel it if you ride hard. In spirited use - frequent Boost, higher cruising speeds - you're realistically looking at medium-long rides, not epic tours. For a typical suburban commute and some fun detours, it's perfectly adequate. But if you're the type who joins big weekend group rides or wants to explore all day without thinking about charging, you'll bump into its limits sooner than with the Storm.

On the charging side, the Storm claws back some practicality thanks to the included fast charger; plugging the pack in at home while the chassis stays locked downstairs is genuinely convenient. The GT2's charging is slower unless you invest in dual chargers, and you're charging the whole hulking scooter as a unit.

Range anxiety: on the Storm, basically none unless you're doing truly silly distances or riding flat-out everywhere. On the GT2, you'll be mildly aware of the gauge on very spirited days, but for "normal human" usage it isn't a big stressor.

Portability & Practicality

Let's be honest: both are terrible to carry. The question is which is the least impractical.

The Storm New EY4 is the heavier of the two, and you feel every extra kilo the moment you try to lift the front end over a kerb or wrestle it up a step. Folded, it's still a long, dense rectangle of aluminium and rubber. The one huge advantage is the removable battery: if you live in a building with secure ground-floor storage but no convenient socket, you can leave the body downstairs and just lug the pack. That pack is no feather, but it's a lot more manageable than the whole scooter.

The GT2 isn't exactly a ballerina either, but it's a touch lighter and better balanced when you're shuffling it around garages or lifts. The folding system is robust but not particularly compact - it's the kind of scooter you roll into a big lift or wheel into a garage, not something you tuck under a café table. Getting it into a small car boot is an exercise in creative swearing.

For daily "living with it":

• Storm: better for people who need to charge away from where the scooter is stored, worse for any scenario involving carrying the whole thing.
• GT2: better if you have ground-floor access or a car and just want to roll it in and out without thinking about removable bits.

Safety

Both manufacturers clearly know that standing at highway-ish speeds is inherently daft and have tried to mitigate that.

The Storm New EY4 leans on brute-force safety: big hydraulic discs, strong motor braking, very bright dual headlights and a whole circus of RGB to make you visible from orbit. The wider bars and improved stem clamp make it far more stable than older Dualtrons at speed, and once set up properly it feels secure when you're really moving. Lighting is finally good enough that you're not forced into aftermarket torches for night riding.

The Segway GT2 adds brains to the brawn. You still get serious hydraulic brakes and strong lighting, but the traction control is the headline act. On wet roads, dust, gravelly patches in corners - all the stuff that ruins your day on high-power scooters - the GT2 quietly manages wheel slip before it becomes drama. Combined with that sophisticated front suspension geometry, you get less twitching and fewer heart-in-mouth moments. It feels like the scooter is working with you, not just waiting to punish your mistakes.

Stability at speed is excellent on both, but the GT2 edges it in "I feel like I could do this all day without dying" confidence. The Storm is safe enough in capable hands, but it absolutely expects those capable hands.

Price & Value

Neither of these scooters is remotely cheap, and both sit squarely in "considered purchase" territory.

The Storm New EY4 undercuts the GT2 slightly in many markets, while offering a bigger battery and more savage performance ceiling. If your metric is "how much voltage and wattage per euro", the Dualtron looks more attractive. You also get a fast charger in the box and a removable pack, which does add real, everyday value for a certain kind of rider.

The GT2 asks more money for less outright battery and a lower top speed. On a spreadsheet, it loses. But it gives you tech the Storm doesn't - traction control, more advanced suspension design, that HUD-style display - and a more polished ride out of the box. You're buying refinement, brand ecosystem and safety tech as much as hardware.

Put simply: Storm is better "numbers value" for power and range; GT2 is better "experience value" if you care about how composed the ride feels rather than how far the spec sheet stretches.

Service & Parts Availability

The Dualtron Storm New EY4 benefits from Minimotors' long-standing presence in the high-performance segment. In Europe, parts, third-party upgrades, and community knowledge are plentiful. Need a specific rubber cartridge, brake rotor, or controller? Someone has it, or knows where to get it. You are, however, a bit at the mercy of your local distributor for warranty attitude; experiences can vary, but the ecosystem itself is mature.

Segway, via Ninebot, is a global giant with strong distribution and generally reliable access to official service centres and spares. The flip side is that the GT2 uses a lot of proprietary bits. That's fine while everything is in production; longer term, it can make DIY tinkering trickier than with the more "Lego-like" Dualtron universe. For plug-and-play owners who just want an official shop to handle issues, the GT2 is friendly. For garage tinkerers, the Storm is more open.

Final Verdict - Which Should You Choose?

The Segway GT2 is the more rounded machine for most riders. It rides better on real, imperfect roads, feels calmer when you're pushing on, and adds tech that quietly keeps you upright when conditions are less than perfect. If you want a hyper scooter that behaves like a well-sorted grand tourer rather than a tamed track weapon, the GT2 simply makes more sense day-to-day.

The Dualtron Storm New EY4 is for a narrower but very real niche: riders who care more about maximum range, raw torque and the practicality of a removable pack than about ultimate polish. If you're heavier, have long daily distances, store the scooter away from power, or just want that old-school Dualtron punch with some modern upgrades, the Storm answers those needs better than the Segway.

If I were advising a typical enthusiast commuter with mixed city and suburban riding, I'd nudge them towards the GT2: it's easier to live with and easier to ride fast without constantly managing the scooter's moods. If you already know you value brute power, huge battery and a modular battery system above refinement - and you're prepared to work with its heft and firmer ride - then the Storm New EY4 will scratch that itch more thoroughly.

Numbers Freaks Corner

These metrics strip things down to pure maths: how much you pay and carry per unit of energy, speed or power, how efficiently each scooter turns watt-hours into kilometres, and how fast they recharge. Lower "per something" numbers are generally better for cost and practicality; higher power-to-speed and charging wattage numbers indicate stronger performance and shorter charging windows.
