Fast Answer for Busy Riders ⚡ (TL;DR)
The Dualtron Thunder 2 EY4 is the more rounded, confidence-inspiring scooter: it pulls harder than common sense, goes seriously far on a charge, and feels like a single, overbuilt piece of machinery under your feet. The Storm New EY4 fights back with more peak power on paper and that removable battery, but its extra weight and slightly more demanding nature make it feel less effortless in day-to-day use.
If you live in a flat, need to carry the battery upstairs, and want a brutal straight-line machine with proper built-in headlights, the Storm New EY4 makes sense. If you just want the scooter that rides better, feels tighter, and delivers the best overall hyper-scooter experience for your money, go Thunder 2 EY4.
Stick around for the full comparison - the devil (and the fun) is in the details.
Hyper-scooters used to be fringe toys for a handful of lunatics. Now, 72V monsters like the Dualtron Thunder 2 EY4 and the Dualtron Storm New EY4 are becoming the "endgame" choice for riders who've long outgrown commuter toys and want something that can actually replace a car for many trips. Both come from Minimotors, both wear the Dualtron badge like armour, and both will happily push you to speeds that make you rethink your life insurance.
On paper, they live in the same world: huge dual motors, big LG batteries, rubber suspension, hydraulic brakes, the new EY4 cockpit and app. In practice, they're surprisingly different: the Thunder 2 feels like a brutally fast but sorted road weapon, while the Storm New is more of a modular torque hammer with a party trick battery and a bit more drama baked in.
If you're torn between them, this comparison will walk you through what actually matters once the spec-sheet honeymoon is over: how they ride, how they live with you, and which one you still want to roll out of the garage after a long week.
Who Are These For, and Why Compare Them?
Both scooters sit in the "hyper" category - not toys, not last-mile commuters, but full-on vehicles. They cost roughly what a half-decent used hatchback does, they weigh more than many e-bikes, and they will absolutely punish mistakes if you treat them like rental scooters.
The Thunder 2 EY4 is for the rider who wants a ferociously fast, long-range road bruiser that feels cohesive and reassuringly sorted. Think: serious daily or weekend mileage, big group rides, highway-adjacent speeds, and "buy once, keep for years".
The Storm New EY4 is for the rider whose life logistics are awkward: no garage power, stairs between you and the charging socket, but still a need (or desire) for 72V madness. The removable battery, brighter stock headlights and slightly more "feature flagship" vibe are its calling cards.
They're natural rivals: similar performance class, same brand, similar money, similar range. One is the evolution of the legendary Thunder line, the other is the rework of Dualtron's modular Storm concept. Choosing between them is less about "which is crazy fast?" and more about "which kind of crazy suits me?"
Design & Build Quality
Both scooters look like they've escaped from a cyberpunk film set, but they speak different dialects of the same language.
The Thunder 2 EY4 has that low, dense, "brick of metal on wheels" feel. The deck is a solid slab with a thick rubber mat, the rear spoiler/footrest is integrated and purposeful, and the whole chassis feels over-engineered. When you grab the stem and rock it, nothing moves that shouldn't. Wiring is still recognisably Dualtron - some visible spaghetti near the bars - but much tidier than the old days, and the finish is mature: matte black, clean, purposeful, less showy, more weapon.
The Storm New EY4, by contrast, looks a bit more theatrical. Same industrial DNA, but with a chunkier silhouette and that big battery box forming the deck. The removable pack adds seams and hardware you don't see on the Thunder 2. Nothing feels cheap - this is still tank territory - but you are always aware that the deck is a separate piece of hardware rather than part of one continuous monolith. It's functional, but visually and tactilely a bit less "one piece of billet" than the Thunder.
Where the Storm claws back points is the cockpit and lighting. Both share the EY4 display, which finally gives Dualtron a modern, bright, waterproof dash in the middle instead of the old trigger-pod. But the Storm's wider handlebars and beefed-up stem assembly give a slightly more "big bike" stance when you're standing behind it. Add the serious stock headlights and the scooter has more showroom "wow" out of the box.
Overall build quality on both is very high, but the Thunder 2 feels tighter and more cohesive, whereas the Storm New EY4 feels more modular and slightly more complex. If you like the impression of a single, carved-from-one-block machine, the Thunder 2 wins this round.
Ride Comfort & Handling
Both scooters use Dualtron's rubber cartridge suspension. That means: firm, sporty, and stable at speed, not soft and floaty like coil-sprung rivals. On smooth tarmac they feel like fast sports cars. On broken city surfaces, they feel like fast sports cars on low-profile tyres - you will know where the potholes are.
On the Thunder 2 EY4, the stock cartridges are unapologetically stiff. At moderate speeds on mixed urban roads, you feel sharp edges and scars, but once you let it stretch its legs, that firmness suddenly makes sense. The chassis stays level under brutal acceleration, and mid-corner bumps don't unsettle it as much as you'd expect. The wide, ultra-square tyres add to this planted feel in a straight line, though they do make quick direction changes feel a bit like persuading a very large dog to change its mind - you have to tell it, not ask it.
The Storm New EY4 rides in a very similar way, but the extra mass is noticeable. It bulldozes through smaller imperfections simply because of its weight, yet on really messy roads the same firm cartridges and heft start to work against you: repeated hits can become tiring, especially if your city likes cobblestones. The wider handlebars do help with leverage and make steering corrections more relaxed, but the scooter never quite shakes that "big, heavy machine" sensation.
Both can be tuned with different suspension cartridges. With some time, tools and willingness to experiment, you can soften either to suit your weight and roads. But out of the box, the Thunder 2 feels a touch more agile and controlled, while the Storm New leans more towards heavy, fast cruiser with a slightly less forgiving attitude when the tarmac gets nasty.
Performance
Let's be honest: neither of these scooters is lacking in power. They both belong firmly in the "accidentally scream inside your helmet the first time you floor it" category.
The Thunder 2 EY4 hits that sweet spot where obscene acceleration meets good manners. The dual motors and 72V system deliver a shove that feels like someone has tied a winch to your chest and hit "retract". The front end doesn't go light as easily as some rivals because the chassis is long, low and stable, and that rear spoiler lets you really drive your weight back. The overtake mode, when you trigger it, is comedy: the scooter goes from "this is very fast" to "this is getting slightly irresponsible" in a heartbeat.
Throttle mapping is classic Dualtron: a bit abrupt at walking speeds, requiring a delicate index finger, but once you're rolling it becomes progressive and predictable. It's aggressive, but not unpredictable. Hill starts with a heavy rider and steep gradients feel like starting on level ground. The Thunder 2 simply doesn't acknowledge the existence of inclines in the way lesser scooters do.
The Storm New EY4 on paper has even more peak output, and you can feel that in the way it digs in off the line. The first few metres can be slightly more dramatic; the front wants to lighten up if you're lazy with stance, and the heavier body leans more on that massive torque. Once up to speed, it surges strongly and just keeps pulling, but it feels a bit more "brute force" than the Thunder 2, which comes across as more balanced between front and rear ends.
Both can push into territory that starts to feel like small-motorcycle speed, and both are happiest with a rider who understands weight transfer and has the gear to match. The Storm New feels just a bit more like a dragster - torque everywhere, slightly more effort to keep perfectly settled. The Thunder 2 feels slightly more sorted and confidence-inspiring when you're really carrying speed.
Battery & Range
Battery-wise, we're in "silly big" territory on both scooters. They both use high-quality LG 21700 cells and live in the same general range ballpark in real use.
The Thunder 2 EY4 carries a noticeably larger pack. In the real world - mixed speeds, proper fun, some hills - it comfortably delivers long group rides without range anxiety. Even when you ride like a teenager who's just discovered Turbo mode, you still get the kind of distance that most people only see in eco-fantasy marketing numbers on cheaper machines. In more measured riding, you're looking at all-day usability on a single charge.
The Storm New EY4's pack is slightly smaller, but still firmly in the "why are you even worried?" class. Range on the road is very similar when you ride both with the same level of restraint (or lack of it). The difference only really shows if you're deliberately stretching distance: the Thunder 2 goes that bit further before you start thinking about the charger.
Where the Storm has a very real advantage is charging logistics. The removable pack means you don't have to own a house with a garage plug to run a hyper-scooter. You can leave 55-plus kilos of chassis locked downstairs and carry only the battery. It also ships with a proper fast charger, so getting from mostly empty to full within a workday or overnight is easy. The Thunder 2's huge pack takes quite a while on the stock charger, and most owners end up buying a fast unit to make the charging experience match the riding experience.
So: if you prioritise maximum on-board energy and fewer charging stops, the Thunder 2 quietly wins. If your reality is "third-floor flat, no lift" and you need that removable battery, the Storm New uniquely solves a problem few other hyper-scooters can touch.
Portability & Practicality
Let's get this out of the way: neither of these scooters is portable in any sane sense. You don't "carry" them - you negotiate with them.
The Thunder 2 EY4 is already massively heavy. Lifting it into a car boot is a gym session. You don't take it on trains unless you enjoy suffering and angry stares. The folding stem is robust but fiddlier than commuter scooters, and the sheer mass means you generally roll it everywhere rather than picking it up. If you have ground-floor storage or a garage, this is a non-issue; if you don't, it's a deal breaker.
The Storm New EY4 then turns the dial further. That extra weight is very noticeable the first time you try to pivot it in a hallway or up a curb. Yes, the handlebars fold, and yes, it becomes slightly less of a space hog, but moving it around tight spaces is always a wrestle. Its saving grace is the removable battery. Being able to strip a big chunk of weight off the deck before shuffling the chassis around is a genuine quality-of-life improvement if your parking situation is awkward.
On day-to-day practicality, both have good water protection, solid stands (if still a bit marginal for the sheer mass), proper lights and indicators, and a cockpit that finally feels like it belongs in this decade. The Thunder 2 is simply easier to live with if you roll it in and out of a garage or ground-floor space every day. The Storm New is the only realistic hyper option for many flat-dwellers, but you pay for that flexibility with extra weight and a slightly more complicated routine.
Safety
Both scooters take safety far more seriously than the "hold my beer" era of early Dualtrons, and that's good, because their performance demands it.
Braking performance is excellent on both. The Nutt hydraulic callipers, large rotors and strong electronic braking give you real motorcycle-grade stopping power. Lever feel is progressive, and with a bit of setup, you can go from gentle speed trimming to full emergency stop with one or two fingers. Dualtron's electronic ABS is still a bit of a "Marmite" feature with its pulsing sensation, but it does help you stay upright when panic grabbing the levers on sketchy surfaces.
Lighting is where the Storm New EY4 pulls ahead. Its stock headlights are genuinely usable for fast night riding; you can see far enough ahead to relax at speed, not just be visible. The Thunder 2's lighting is vastly better than the original Thunder - especially the raised rear light and indicators - but the low-mounted front units still feel more "be seen" than "see everything". Most Thunder 2 owners I know strap an auxiliary light to the bars for serious night work; Storm riders are more likely to ride stock.
Stability-wise, both are light-years ahead of early Dualtrons. The Thunder 2's double-clamp and beefed-up stem make it feel like one rigid spear at speed; the Storm New backs that up with a wider handlebar and reinforced column. At very high speeds, I find the Thunder 2 just that bit calmer and easier to keep arrow-straight. The Storm feels secure, but the extra mass and torque can make small rider inputs translate into slightly bigger reactions until you're dialled in.
Either way, with both scooters you are in a zone where helmet, gloves, body armour and sensible judgement are not negotiable. The hardware has caught up; the weak point is now the rider.

Price & Value
Both scooters sit in the premium tier. You're paying real money, and you should expect real engineering in return.
The Thunder 2 EY4 undercuts the Storm New slightly while giving you a bigger battery and a very similar performance envelope. That alone gives it a quiet advantage in value. It feels like you're getting the full Dualtron experience - big power, big range, top-tier parts support - without paying extra for party tricks.
The Storm New EY4 asks a bit more and mostly justifies it if you specifically need what it offers: removable battery, stronger stock lighting, wider bars, and the "Storm" flagship aura. As a pure euros-per-range and euros-per-speed proposition, it's not the bargain of the century - there are cheaper scooters with comparable straight-line stats - but they rarely match its ecosystem, build maturity and modular battery concept.
If you strip emotion out and look purely at how much scooter you get for the money, the Thunder 2 has the edge. The Storm New EY4's value lives in its niche: when removable battery and apartment-friendliness are the deciding factors, it suddenly makes perfect sense.
Service & Parts Availability
On this front, both scooters benefit from wearing the Dualtron badge. Minimotors has one of the strongest global ecosystems in the e-scooter world: established European distributors, good parts pipelines, and a large aftermarket scene.
Brake pads, tyres, cartridges, controllers, throttles - you can get them for both Thunder 2 and Storm New without exotic parts hunting. The EY4 display, being common across newer Dualtrons, should also be well supported for years. Independent shops across Europe increasingly know their way around these chassis, which helps when you don't want to wrench everything yourself.
The removable battery of the Storm New adds one wrinkle: it's another high-value component you need to keep an eye on, and replacing it is a serious investment if you ever need to. The Thunder 2's fixed pack is simpler from a user perspective; you treat the whole scooter as one unit for service and storage. Both can be maintained at home by a patient, moderately handy owner, but the Thunder 2 is a bit more straightforward mechanically.

Final Verdict - Which Should You Choose?
If you strip away the spec-sheet hype and look at what it's like to genuinely live with these scooters, the Dualtron Thunder 2 EY4 comes out as the more complete, better-balanced machine. It accelerates like a lunatic, yet feels reassuringly composed doing it; it goes further on a charge; it weighs less; and it costs a bit less while still giving you that top-shelf Dualtron experience. When you're hundreds of kilometres into ownership, it's the one that tends to feel like a trusted weapon rather than a constant project.
The Storm New EY4 absolutely has its place. If the removable battery solves your living situation, or if you put a big premium on stock lighting and the slightly more "flagship toy" vibe, it might be the better fit. Heavy riders who really exploit that higher load rating may also gravitate towards it. Just go in knowing you are choosing extra complexity and weight for that modularity and brightness.
For most riders who simply want a hyper-scooter that feels cohesive, brutally fast and surprisingly confidence-inspiring, the Thunder 2 EY4 is the one that makes you look back at it after every ride. The Storm New EY4 will impress your friends and your neighbours, but the Thunder 2 is more likely to quietly, relentlessly impress you.
