About

If you have been following the high-performance electric scooter scene for any length of time, you know that the name DUALTRON is synonymous with raw power, industrial durability, and a certain "king of the road" attitude. The DUALTRON Storm New EY4 is the latest evolution of one of the most successful hyper-scooters ever built. It represents a significant pivot for Minimotors, the manufacturer, as they have moved away from simply adding more watts and instead focused on refining the rider experience based on actual community feedback. This isn't just a scooter; it is a statement piece that screams performance from every angle.

The philosophy behind the "New" Storm is modernization. The original Storm was a beast, but it had quirks that riders learned to live with. This updated version, featuring the massive EY4 display and a host of structural improvements, positions itself as a mature, reliable, and technologically advanced cruiser. It sits comfortably at the top of the food chain, designed for the enthusiast who wants the adrenaline rush of a racing machine but demands the creature comforts and safety features necessary for 2025 standards. It bridges the gap between a raw track weapon and a high-end commuter vehicle.

What makes this machine truly special in the crowded market of 72V scooters is its modularity and its legacy. Unlike many competitors that are sealed units, the Storm New EY4 retains the iconic removable battery pack-a feature that is shockingly rare in the hyper-scooter category. Designed by the engineers at Minimotors to be the pinnacle of their 72V lineup, it incorporates a sturdier folding mechanism, wider handlebars for stability, and a waterproof display that finally brings the cockpit into the modern era. It is built for the rider who refuses to compromise on build quality.

Safety

When you are piloting a vehicle capable of highway speeds while standing on a deck, safety is not just a feature; it is a survival requirement. The DUALTRON Storm New EY4 takes this seriously, starting with its braking system. It is equipped with NUTT hydraulic disc brakes with massive 160mm rotors. For the uninitiated, hydraulic brakes are a game-changer compared to mechanical cables. They provide immediate, buttery-smooth stopping power with minimal finger effort. Whether you need to shave off speed before a corner or perform an emergency stop in traffic, these brakes provide tactile feedback that inspires massive confidence. Furthermore, the system is paired with magnetic braking assistance (ABS), which uses the motors to help slow the scooter down, saving wear on your brake pads and preventing wheel lock-up.

Visibility has often been an Achilles' heel for high-performance scooters, usually requiring owners to bolt on aftermarket lights. The New Storm addresses this head-on with dual 30W headlights that are exceptionally bright. These aren't just "be seen" lights; they are "see the road" lights, capable of illuminating the tarmac far ahead of you during night rides. The scooter also features a comprehensive lighting package including turn signals, a brake light integrated into the footrest, and the signature RGB stem and deck lighting. While the RGB adds a cool factor, it serves a genuine safety purpose by making the scooter unmistakable to cars from side angles.

Stability at speed is another critical safety component. Minimotors listened to the community complaints about the older, narrower handlebars and upgraded this model with a bar that is 100mm wider. This might sound like a small spec change, but on the road, it provides significantly more leverage, drastically reducing the "twitchiness" that can lead to speed wobbles. Combined with a reinforced steering column and a sturdier folding clamp that eliminates stem play, the ride feels planted and secure, even when you are pushing the throttle toward the limit.

Performance

Let's talk about the elephant in the room: power. The DUALTRON Storm New EY4 is an absolute torque monster. Powered by dual motors that can peak at a staggering 11 500 Watts (combined peak output), the acceleration is visceral. When you pull the trigger, the scooter doesn't just move; it launches. The 72V system provides a relentless surge of power that keeps pulling well past the point where lesser scooters would taper off. For the rider, this means you can overtake traffic with a mere thought and merge into lanes effortlessly. It transforms your city commute into something that feels more like piloting a fighter jet.

Top speed is often a bragging right, and the Storm delivers in spades. While it is electronically limited in many regions to comply with laws, on private land, this machine is capable of speeds exceeding 88 km/h, with some riders pushing toward the 100 km/h mark depending on conditions and charge level. However, it's not just about the top number; it's about how it gets there. The acceleration curve is aggressive, yet the new EY4 display allows for deep customization, letting you dial in the power delivery to suit your skill level. You can tame the beast for a chill cruise or unleash full current for a drag race.

Hill climbing is simply a non-issue for the Storm. With a climbing grade rating of 70% (around 35 degrees), there are very few paved roads on Earth that this scooter cannot conquer. Where 60V scooters might slow down on steep inclines, the Storm accelerates up them. The updated cooling system for the controller is a crucial performance upgrade here, ensuring that the electronics don't overheat during sustained high-power climbs or long, spirited rides. You get consistent power delivery from the start of the ride until the battery begins to drain significantly.

Design

The aesthetic of the DUALTRON Storm New EY4 is pure cyberpunk industrialism. It looks like a piece of military hardware from the future, characterized by sharp angles, exposed aviation-grade aluminum (6082-T6), and a robust, mechanical silhouette. It doesn't try to look friendly; it looks capable. The black finish with the customizable RGB lighting gives it a menacing presence at night. One of the standout design features is the dedicated footrest at the rear, which houses the controller. This not only looks cool but serves a functional purpose by isolating the heat-generating components from the battery and giving the rider a solid leverage point for acceleration.

The folding mechanism has been a point of contention in previous Dualtron generations, but the New Storm features a much more robust system. It uses a heavy-duty sliding collar and double-clamp design that feels rock solid. When locked into place, the stem feels like a single piece of metal, eliminating the dreaded "creak" that plagues cheaper scooters. The wider handlebars also fold down, making the scooter relatively compact for storage, although "compact" is a relative term for a machine of this size.

Perhaps the most brilliant design element is the removable battery pack. The entire deck is essentially a giant battery case that can be unlocked and lifted out. This is a massive advantage for users who live in apartments without elevators or garages with power outlets. You can leave the chassis locked up in a bike room or garage and simply carry the battery inside to charge. It also opens up the possibility of owning two batteries for literally double the range, provided you have the strength and backpack space to transport a spare.

Comfort

Comfort on a Dualtron is a specific experience defined by its signature rubber cartridge suspension system. Unlike the coil-over shocks found on competing brands like Nami or Kaabo, the Storm uses swappable rubber cartridges. This suspension is stiffer and has less travel, which translates to a ride that feels incredibly sporty and connected to the road. It is fantastic for high-speed stability and cornering, as there is very little "bounce" or wallowing. However, on cobblestones or deep potholes, you will feel the road more than on a softer suspension setup. It absorbs the high-frequency vibrations well but is definitely tuned for performance over pillow-like comfort.

The riding ergonomics have been vastly improved with the new 700mm wide handlebars. On the older model, riders with broad shoulders often felt cramped, but the new width opens up your chest and provides a commanding stance. The deck is incredibly wide and long, covered in grip tape that keeps your feet planted. There is ample room to change your foot position during long rides, which is essential for fighting fatigue. The rear kickplate is perfectly angled, allowing you to lean back and lock yourself in against the G-forces of acceleration.

Long rides are surprisingly manageable thanks to the stability of the chassis. While the suspension is firm, the sheer mass of the scooter helps it plow through road imperfections rather than getting bounced around by them. The 11-inch tubeless ultra-wide tires also contribute significantly to the comfort. Being tubeless, they are less prone to pinch flats, and their width provides a larger contact patch, smoothing out minor road buzz and offering tremendous grip in corners.

Range

The heart of this beast is a massive 72V 35Ah battery pack using premium LG 21700 cells. In the world of electric vehicles, battery quality is everything, and LG cells are the gold standard for reliability and discharge rates. The manufacturer claims a maximum range of up to 144 km (90 miles). As with all electric vehicle stats, this is measured under ideal conditions-light rider, flat ground, and moderate speed (Eco mode). However, even in real-world "enthusiast" riding conditions, the range is impressive.

For a typical rider weighing around 80-90 kg, riding at a mix of traffic speeds (30-50 km/h) with occasional bursts of full throttle, you can realistically expect to get between 70 and 90 km of range. If you are pushing the scooter to its limits in Turbo mode constantly, expect that to drop to around 50-60 km. This is still phenomenal and enough to cover almost any urban commute back and forth without charging, or a massive weekend group ride.

Charging such a massive battery takes time. With the standard charger, it can take over 20 hours, which is why the fast charger included in the box is a godsend. Using the fast charger, you can top up the battery in approximately 5 to 6 hours. This makes the scooter viable for daily use, as you can easily get a full charge overnight or even during a workday if you bring the charger (or battery) with you.

Use and Practicality

Living with the DUALTRON Storm New EY4 requires a bit of lifestyle commitment. First and foremost, this is a heavy machine, weighing in at approximately 55,3 kg. You are not going to be carrying this onto a bus, a train, or up three flights of stairs. If you live in a walk-up apartment, the removable battery is your only salvation, allowing you to leave the chassis downstairs. However, even the battery itself is quite heavy, so be prepared for a workout.

In terms of commuting, it is arguably overkill for short trips, but excellent for long-distance suburban commuting. It keeps up with traffic effortlessly, meaning you don't get pushed into the gutter by angry drivers. The IPX5 water resistance rating on the body (and IPX7 on the screen) adds a layer of practicality that was missing from older Dualtrons. While you shouldn't ride it through a lake, getting caught in a rain shower is no longer a death sentence for your electronics, which is a huge relief for daily commuters.

The new EY4 display with Bluetooth connectivity adds a layer of modern practicality. You can connect to the Minimotors app to view detailed stats, adjust settings, and even lock the scooter digitally. The large, colorful screen is easy to read in direct sunlight, showing you speed, battery voltage, and trip data at a glance. The addition of a proper horn, turn signals, and powerful lights means you don't need to strap extra gadgets to your handlebars; it's ready to go out of the box.

General Assessment

The DUALTRON Storm New EY4 is widely regarded by the community as the scooter the original Storm should have been. Minimotors has successfully smoothed out the rough edges of their flagship model. The transition to the EY4 display and the wider handlebars are universally praised improvements that fundamentally change the riding dynamic for the better. It feels like a finished, polished product rather than a prototype.

Among owners, the sentiment is one of immense satisfaction regarding power and reliability. The "Dualtron wobble" is largely gone thanks to the geometry changes, and the electrical systems are proving to be robust. The cooling system upgrades have also been well-received, with fewer reports of overheating controllers compared to the previous generation. It commands respect on the road and in group rides.

However, it is not without its critics. Some riders still find the suspension too stiff for comfortable city cruising on bad roads, preferring the plush feel of trailing-arm suspensions found on competitors. Additionally, the price point places it in a tier where expectations are sky-high, and minor plastic rattles or the need for periodic bolt tightening can be frustrating for some. But overall, it is viewed as a legendary machine that has been successfully remastered.

Who Is This Scooter For?

This scooter is strictly for the experienced enthusiast. If you have never ridden an electric scooter before, do not buy this. The throttle response, even when tuned down, requires a disciplined hand, and the weight requires physical strength to manage at low speeds or when parking. It is designed for the rider who has outgrown their 60V scooter and craves the "endgame" torque that only a 72V system can provide.

It is also the perfect choice for the "garage-less" power user. If you need a hyper-scooter but have nowhere to charge a 55 kg vehicle, the Storm's removable battery makes it one of the only viable options in this performance class. It serves the heavy rider (100kg+) exceptionally well, as the stiff suspension and high-power motors don't sag or struggle under load like lesser machines.

Conversely, this is not for the "last mile" commuter who needs to pop into a coffee shop or fold the scooter under a desk. It is too big, too aggressive, and too flashy. It is a vehicle replacement, not a toy. If you want to replace your car for a 20 km commute to work, this is your machine.

Community Feedback - Pros

Insane Torque: Users consistently rave about the acceleration and the ability to wheelie on demand.
Removable Battery: Cited as the number one selling point for apartment dwellers.
High-Speed Stability: The wider bars and chassis geometry make it feel planted at 80+ km/h.
EY4 Display: The large, waterproof, app-connected screen is a massive upgrade over the old EY3 trigger.
Lighting: The stock 30W headlights are actually usable for night riding, saving money on aftermarket mods.
Braking Power: The NUTT hydraulic brakes are praised for being reliable and strong.
Build Quality: The frame feels bombproof and durable ("built like a tank").
Cooling System: Riders report the controller stays cooler during aggressive riding than previous models.
Parts Availability: Being a Dualtron, spare parts and mods are easier to find than for obscure brands.
Aesthetics: The RGB lights and industrial design get heads turning everywhere.

The most praised aspect of the Storm New EY4 is undoubtedly the combination of the removable battery and the new cockpit experience. Owners love that they don't have to compromise on power to get the convenience of charging indoors. The EY4 display is also a frequent highlight in forums; moving away from the archaic finger-trigger throttle to a more modern interface has modernized the entire feel of the ride.

Community Feedback - Cons

Weight: At over 55 kg, it is physically difficult to lift or maneuver in tight spaces.
Stiff Suspension: Many users complain it is too hard for rough city streets and lacks rebound adjustment.
Throttle Sensitivity: Despite the new display, the square wave controllers can still feel "jerky" or abrupt at low speeds compared to sine wave competitors.
Kickstand: The stock kickstand is often described as too short or flimsy for such a heavy scooter, causing tip-over anxiety.
Price: It is a significant investment, and some users feel it should come with a steering damper included at this price.
Footrest Movement: Some reports of the rubber on the rear footrest shifting or peeling under heavy use.
Stem Maintenance: While improved, the folding mechanism still requires regular checking and tightening to remain creak-free.
Tire Changes: Changing tires on the split rims is easier than standard rims, but still a hassle compared to some single-sided swingarm designs.

The most common gripe is the suspension stiffness and throttle abruptness. While the rubber suspension is great for track-like conditions, real-world riders on potholed streets often wish for adjustable coil shocks. Similarly, while the power is thrilling, the lack of a sine-wave controller means the scooter can feel a bit "all or nothing" at low speeds, making slow maneuvering in traffic require a delicate touch.

Value for Money

The DUALTRON Storm New EY4 generally retails between 3 500 € and 4 000 €, depending on the dealer and region. This places it firmly in the premium luxury segment. Is it worth it? If you value brand heritage, parts availability, and the specific utility of a removable battery, then yes. You are paying a "Dualtron Tax," but in return, you get a machine that holds its resale value better than most and has a massive support network.

However, if you look strictly at specs-per-euro, there are competitors that offer higher top speeds or softer suspension for less money. But those competitors often lack the refinement, the app integration, or the build quality assurance of Minimotors. You are paying for the engineering maturity. The inclusion of the fast charger (often a 150 €+ accessory) in the box adds significant value, as does the upgraded lighting system which negates the need for immediate aftermarket purchases.

Ultimately, it is not a "bargain" scooter, but it is a fair price for a flagship vehicle that serves as a technological showcase. It is an investment in a lifestyle, designed to last for thousands of kilometers.

Known Alternatives

If the Storm New EY4 isn't quite checking all your boxes, there are several other heavy hitters in the market worth considering. One of the most direct competitors from the same family is the DUALTRON Dualtron Thunder 3. The Thunder 3 is often seen as the slightly more aggressive sibling; it features the same EY4 display and general tech but often comes with even more power and a different chassis design that some riders prefer for pure racing. It does not, however, usually feature the removable battery, so if you have a garage, the Thunder 3 might offer slightly higher performance specs.

For those who want the absolute maximum specs available and have a larger budget, the DUALTRON Dualtron Storm Limited is the "big brother" to the standard Storm. The main difference is the voltage; the Limited runs on an 84V system compared to the 72V on the standard Storm. This results in higher top speeds and even more torque. It also typically comes with a steering damper pre-installed and improved tires. If money is no object and you want the fastest Storm variant possible, the Limited is the one to look at.

If you are looking for something slightly different and perhaps a bit better value for money, the MUKUTA Mukuta 10 Plus is an emerging rival. While it may not have the same brand heritage as Dualtron, Mukuta is making waves with high-quality builds and excellent feature sets for the price. It offers a different suspension feel and aesthetic, appealing to riders who want performance but might want to step outside the Minimotors ecosystem.
