Segway GT3 Pro vs Dualtron Storm New EY4 - Two Hyper-Scooters Walk Into a City...

Fast Answer for Busy Riders ⚡ (TL;DR)

The Dualtron Storm New EY4 edges out the Segway GT3 Pro as the more capable all-round hyper-scooter: it hits harder, goes further in the real world, and its removable battery makes it easier to live with if you can't charge in a garage. The GT3 Pro fights back with a more polished, "consumer electronics" feel, softer suspension and friendlier ride manners, making it less intimidating for riders stepping up from mid-tier machines. Pick the Storm if you prioritise raw performance, range and long-term tunability; pick the Segway if you care more about refinement, comfort and a more plug-and-play ownership experience. Both are heavy, overkill beasts - the key is which compromises you're willing to live with.

Stick around and we'll unpack how each one behaves when the spec sheet meets real, ugly tarmac.

There was a time when a "fast scooter" meant something that could just about outrun a jogger. Those days are gone. The Segway GT3 Pro and Dualtron Storm New EY4 sit at the opposite extreme: they're closer to compact electric motorbikes with decks than anything you'd casually fold into a train.

I've spent a fair amount of saddleless time on both - enough kilometres to learn which one keeps you grinning on a bad road, which one drinks its battery like a teenager at an open bar, and which one you regret having to drag up a ramp at the end of the day. They occupy the same 72V hyper-scooter universe, but they approach it with very different philosophies.

If you're wondering which of these monsters you should actually buy - or whether you should back slowly away and buy something sane - read on. The devil here isn't in the numbers; it's in how those numbers feel when you twist the throttle.

Who Are These For, and Why Compare Them?

Both the GT3 Pro and the Storm New EY4 live in the "I could have bought a small used car instead" price bracket. They're built for riders who have blown past rental scooters and commuter toys and now want something that can keep up with city traffic, eat long distances, and genuinely replace a car for many trips.

On paper, they're direct rivals: big 72V systems, dual motors, serious brakes, proper lighting, hulking frames and eye-watering price tags. In practice, they're aimed at slightly different mentalities:

Segway GT3 Pro: for riders who want a hyper-scooter that still feels like a refined consumer product - polished software, plush suspension, lots of safety aids, minimal tinkering.

Dualtron Storm New EY4: for the veteran enthusiast who wants torque, range and a platform that invites tweaking, with a removable battery solving the "I live upstairs" problem.

They're competitors because they sit in the same performance class. You're unlikely to cross-shop either of them with a 20 kg city scooter unless you've mis-clicked horribly.

Design & Build Quality

Pick up the Segway (or rather, try to) and the first impression is "finished product". The frame has that sculpted, hollow-neck design Segway loves: angular, futuristic, and clearly not bought from a generic factory catalogue. Cable routing is tidy, plastics are tight, and the whole thing has the vibe of a premium e-bike that wandered into a cyberpunk film set. Nothing rattles when you smack the deck with your fist - it feels cohesive.

The Dualtron, by contrast, is pure industrial hardware. Exposed aluminium, chunky welds, big bolts everywhere. The Storm New EY4 looks like it escaped from a lab where they test components to destruction, shrugged, and kept going. Fit and finish on the main chassis are excellent, but it's more "tank with LEDs" than "Apple with wheels". Some smaller bits - kickstand, a few plastics - remind you this is still a Korean performance brand first, lifestyle brand second.

Ergonomically, the GT3 Pro is more immediately approachable. The cockpit controls feel like they were designed by someone who actually rides in gloves; the buttons have clean clicks, the colour display is crisp and easy to read in daylight, and the whole bar layout is intuitive. The Dualtron's new EY4 cockpit has finally dragged Minimotors into the modern era - wide screen, app connectivity, more adjustability - but the overall feel is a little more utilitarian. Functionally great, aesthetically a bit "aftermarket LCD stuck on a bar".

Both scooters feel serious and solid. The Segway wins on visual polish and perceived integration; the Dualtron wins on "I'm not breaking this frame in a hurry" confidence. Hands-on, the GT3 feels like a premium gadget, the Storm like specialised equipment.

Ride Comfort & Handling

This is where their personalities really diverge.

The Segway GT3 Pro rides like someone took a luxury SUV and shrunk it onto two 11-inch wheels. Its hydraulic suspension, with that car-style front linkage, soaks up city nastiness with ease. Cracked bike lanes, lazy speed bumps, rough asphalt - the GT3 just floats. After several kilometres of cobbles, my knees and lower back still felt surprisingly fresh. You can ride it fast on bad surfaces without constantly bracing for impact, which does wonders for fatigue.

The Dualtron Storm New EY4 is firmer. That rubber cartridge suspension gives you a more "connected" feel to the road - great for carving and high-speed stability, less great when your council forgets how to fill potholes. It filters out high-frequency chatter well, but deeper holes and sharp edges definitely make themselves known. After a long inner-city slog on rough surfaces, you'll know you've been standing.

In corners, the picture flips slightly. The Storm's wider bars and firmer suspension make it feel like a big, planted longboard. Once you commit to a line, it holds it with impressive composure. At speed, gentle bar inputs result in predictable, calm arcs - the extra leverage from those broad handlebars really helps curb any twitchiness.

The GT3 Pro is stable, but it has more vertical movement in the suspension. That's lovely for comfort, but if you really start charging through fast sweepers on uneven roads, you feel a bit more "float" and chassis movement. It's absolutely fine at sensible (and slightly less sensible) speeds, but the Dualtron gives more confidence when you're pushing the upper end of what's reasonable on tiny tyres.

For everyday mixed riding, the Segway is the more relaxed partner; for aggressive carving on halfway-decent tarmac, the Storm feels more dialled in - as long as your spine is on board with the plan.

Performance

Neither of these scooters is slow. The difference is in how they try to detach your arms.

The GT3 Pro hits hard by mainstream standards. That 72V system and dual motors give you instant, satisfying punch off the line. In its sportier modes, it pulls with enough enthusiasm that new riders will instinctively lean back and grab the rear kickplate on the first launch. Overtaking slower traffic, climbing meaningful hills, or blasting up bridges feels almost effortless. It's fast enough that, on normal roads, you're limited more by your nerve than the hardware.

Then you ride the Dualtron Storm New EY4 and realise what "hyper" really means. The combined peak output here is in another league: you don't just accelerate, you get yanked. Even after many kilometres, I still catch myself chuckling when I open it up from a crawl - it's explosively quick. Where the Segway surges, the Dualtron erupts. On steep hills, the GT3 Pro powers up decisively; the Storm feels like it's offended the hill even exists.

Top speed comfort is another separator. Both will go deep into "this is now a motorbike problem" territory, but the Storm has more headroom up top and feels particularly composed there, helped by the geometry and wide bar. The Segway, with its more comfort-focused suspension, feels calmer at medium-fast cruising speeds than at absolute max; it's very stable, but you're more aware of movement over waves in the surface.

Braking performance on both is strong and confidence-inspiring. The GT3 Pro's hydraulic discs paired with its electronic S-ABS give a calm, controlled deceleration - you can really trail-brake into corners or scrub speed hard without the wheels locking up easily. The Storm's big hydraulic discs plus magnetic motor braking feel more aggressive when you really haul on them. It scrubs speed extremely quickly, with the motors helping to slow you down and taking some load off the pads.

In city riding, the GT3's traction control is genuinely useful. Hammering the throttle on wet manhole covers or loose dust would be asking for trouble on many scooters; the Segway quietly intervenes, smoothing out antics before they become crashes. The Dualtron gives you more raw, uncensored power at the wheel. Experienced riders will love that; beginners may find the throttle a bit abrupt at very low speeds, especially in the punchier settings.

Battery & Range

Both of these come with batteries that make budget scooters look like key fobs. Range, however, is not just a number - it's how often you're thinking about where the next socket is.

The GT3 Pro's pack is big, and ridden sensibly you can absolutely cross an entire city and back without the battery indicator turning into a countdown clock. When you ride it the way it invites you to - brisk cruising, plentiful bursts of throttle - you're realistically looking at long, solid rides before you need to plug in, but not some mythical all-day epic. At sustained high speeds, you can practically watch the percentage tick down if you're paying attention.

The Dualtron Storm New EY4 ups the ante with an even larger battery using high-quality LG cells. In similar mixed riding - flowing with traffic, plenty of hills, the occasional childish full-throttle moment - it simply goes further before complaining. If you push both scooters equally hard, the Storm lets you be stupid for longer. And if you ride them like a sensible adult, both are perfectly viable for very long commutes; the Dualtron just gives you a bit more safety margin.

The big structural difference is that removable battery on the Storm. Range anxiety is one thing; charging logistics anxiety is another. With the Dualtron, you can leave the hulking chassis locked downstairs and carry only the pack to your flat. You can even keep a second battery if your wallet and back both enjoy punishment, effectively doubling your usable range. The Segway's integrated pack means the entire 50-plus kilo beast has to live wherever your power outlet is.

Charging time is another practical angle. The GT3 Pro's pack, charged with its standard charger, is a classic "plug in overnight and forget about it" situation. The Storm ships with a fast charger, making a large top-up over the course of a working day or long lunch realistically doable. For daily heavy use, that faster recharge routine and removable pack are hard to ignore.

Portability & Practicality

Let's be blunt: neither of these scooters is portable in any sane sense. We're choosing between "awkward" and "slightly more awkward".

The Segway GT3 Pro is heavy, but the folding mechanism is beautifully executed. The stem clamp locks with an almost arrogant sense of solidity - no creaks, no play, no "is this really safe?" doubt. Folded, the scooter is still long, still wide, and still not something you want to carry further than a few metres. Stairs? Only if you're built like a powerlifter and very motivated.

The Dualtron Storm New EY4 is even heavier. Folding is straightforward but more old-school: big clamp, sliding collar, clearly designed with strength first and elegance a distant second. Once folded, it's a chunky, dense block that you wrestle rather than lift. The saving grace is again that removable battery - you can lighten the chassis a bit by taking the pack out for moving or transport, which does help on ramps or when you're trying to get it into a car.

As day-to-day tools, both work well if you can roll them straight out of ground-floor storage. For car transport, the Segway's integrated design and fixed battery make it more of a single lump; the Storm splitting into frame plus pack can sometimes be easier to juggle if you're creative. For anything involving trains, buses or loft apartments, both are firmly in "what were you thinking?" territory.

Safety

Both scooters take safety more seriously than most riders will on day one.

The GT3 Pro's biggest advantage is how it quietly watches your back. Traction control, anti-lock braking, self-sealing tyres, a very solid chassis and a genuinely bright headlight all combine into a package that does its best to keep bad decisions from becoming hospital visits. At city speeds in the dark, the headlight actually shows you what's coming, rather than just decorating the front of the scooter. The heavy frame and long wheelbase give it a planted feel when the road surface gets sketchy.

The Dualtron Storm New EY4, meanwhile, leans on raw hardware and redundancy: huge hydraulic brakes plus magnetic braking, two strong headlights, a full indicator and brake light suite, and lots of side visibility thanks to its RGB lighting. Its stability at higher speeds is excellent once you've got tyre pressures and bar alignment sorted, and the wider bar really does help keep wobbles at bay. Water resistance is also a tick in its safety/protection column; getting caught in the rain is less nerve-wracking when you know the electronics are designed to cope.

At moderate speeds on patchy surfaces, the Segway's softer suspension and clever electronics feel more forgiving. At higher speeds on better tarmac, the Dualtron's stiffer setup and wider cockpit provide more outright stability. Both can be safe machines if ridden with respect; both can also get you into trouble surprisingly quickly if you bring a rental-scooter mindset.

Price & Value

Both scooters cost serious money; we're debating degrees of expensive here, not value picks.

The GT3 Pro sits a bit lower on the price ladder than the Storm New EY4. For that, you get a thoroughly integrated, refined machine with very usable performance, genuinely excellent comfort, and big-brand backing. You also get less outright power and a slightly smaller battery than the Dualtron. If you care more about the day-to-day feel than absolute numbers, the Segway's price can be justified - but it's not the king of "specs per euro".

The Storm New EY4 charges a noticeable premium. In return, you get more motor, more battery, faster charging included, and that unique removable pack. You also buy into the Dualtron ecosystem: easy access to parts and upgrades, widespread dealer and community knowledge, and strong resale. On paper, the numbers-per-euro lean towards the Storm; in practice, whether it's "worth it" depends on whether you'll actually use the extra capability.

If your riding is mostly medium-speed commuting with the odd weekend blast, the Segway's lower price and cushier manners look reasonable. If you're doing long distances, riding hard, or you need the removable battery, the Dualtron justifies its higher ticket better.

Service & Parts Availability

Segway is the giant of the industry. That brings pros and cons. On the plus side, basic parts availability is generally decent in Europe, and any half-competent scooter shop has at least some experience with their products. On the minus side, you're dealing with big-company support structures: ticket systems, regional importers, and the occasional game of "which department handles this?". Warranty experiences are mixed - some riders report smooth resolutions, others a lot of waiting.

Dualtron, via Minimotors and its European distributors, is more niche but very well established in the enthusiast space. Frame parts, controllers, throttles, cartridges, brake bits - you can find them through a network of dealers and a thriving aftermarket. Community-made guides on fixes and upgrades are everywhere. The flip side is that the brand still assumes you or your dealer are comfortable turning spanners now and then; this isn't a "never open the toolbox" ownership experience.

If you want something you'll mostly hand to an official service centre and forget about, Segway fits that mentality a bit better. If you're fine with (or even enjoy) the occasional weekend of maintenance and ordering specific parts from specialist shops, the Dualtron ecosystem is richer.

Final Verdict - Which Should You Choose?

If you strip away the marketing gloss, this is a choice between a hyper-scooter that tries to look after you (Segway) and a hyper-scooter that assumes you know what you're doing (Dualtron).

The Segway GT3 Pro is the better pick if your roads are rough, your spine is picky, and you want a big, fast scooter that doesn't constantly demand your full attention. Its suspension really is a level softer and more forgiving, its electronics quietly keep you out of trouble, and the whole thing feels like a premium, integrated product. If your typical ride is a long-ish commute at brisk but not insane speeds, the GT3 Pro will get you there quickly and in surprising comfort, with enough drama to be fun but not so much that you're tense the whole time.

The Dualtron Storm New EY4, by contrast, is the one you buy when you want performance first and can live with the rest. It hits harder, goes a bit further, and charges faster. The removable battery is a game-changer for anyone without ground-floor charging, and the Dualtron ecosystem gives you more avenues to tweak, tune and repair over the long term. It's less forgiving out of the box - firm suspension, snappier throttle - but if you're an experienced rider who actually uses the top half of the speedometer, it feels like the more capable machine.

For most riders who simply want a very fast, very solid scooter that's still somewhat civilised, the Segway GT3 Pro will be easier to live with day to day. For the hardcore enthusiast, long-distance rider or apartment dweller who needs maximum flexibility and doesn't mind a stiffer, more aggressive character, the Dualtron Storm New EY4 is the one that ultimately makes more sense.

Numbers Freaks Corner

These metrics give a purely numerical view of efficiency and value: how much you pay for battery and speed, how heavy the scooter is relative to its energy and performance, how efficiently it uses its battery in the real world, and how fast it charges. Lower scores generally mean better "bang per gram" or "bang per euro", while the higher-is-better metrics (power density and charging speed) indicate how aggressively the scooter converts energy into performance and how quickly you can get back on the road.
