Teverun Fighter Supreme Ultra vs Dualtron Storm New EY4 - Which Hyperscooter Actually Deserves Your Money?

Fast Answer for Busy Riders ⚡ (TL;DR)

The Teverun Fighter Supreme Ultra is the more complete hyperscooter here: smoother power delivery, bigger battery, richer feature set and a noticeably better ride/comfort balance, all while undercutting the Dualtron on price. It feels like a modern, thought-through vehicle rather than a fast relic with some new tech bolted on.

The Dualtron Storm New EY4 still makes sense if you specifically need the removable battery, love the Dualtron ecosystem, or want that classic, stiff, sporty feel with legendary parts availability. It's a solid, brutally quick machine - just not the best value or most refined option in this head-to-head.

If you care about range, comfort, and everyday usability as much as sheer speed, keep reading - this comparison might save you a few thousand Euros and a lot of future "I should've bought the other one" regret.

Hyper-scooters used to be fringe toys for adrenaline junkies. Now they're legitimate car replacements - and these two are right in that "sell the second car, keep the scooter" territory. On one side, the Teverun Fighter Supreme Ultra: a fresh-generation brute with a brain, clearly designed by people who actually commute on these things, not just drag race them in car parks.

On the other, the Dualtron Storm New EY4: the latest chapter of an iconic line that practically invented the high-power scooter category, now updated with a big, modern display and a few long-overdue fixes. It's the evolution of an old king that still doesn't like giving up its crown.

The Ultra is for riders who want ridiculous range and real refinement in one package. The Storm EY4 is for those who worship the Dualtron name, want a removable battery, and accept a firmer, more old-school ride. Let's dig in and see which one deserves space in your garage - and which one might stay in the shop window.

Who Are These For, and Why Compare Them?

Both scooters live in the same rarified air: heavy, brutally powerful, long-range 72 V machines that can comfortably replace a car for most daily use. They're aimed at experienced riders who already know what "Eco mode" feels like on a 60 V scooter and are now hunting for their "endgame" machine.

Price-wise, they sit in the premium segment - but not the absurd "custom build with gold bolts" tier. The Storm EY4 costs noticeably more, drifting toward boutique pricing, while the Fighter Supreme Ultra squeezes into a friendlier bracket despite packing a bigger battery and a fatter feature list. They share similar top-speed potential, similar physical heft, and equally serious hardware. That makes them natural rivals.

If you're looking at either of these, you're not asking "Is this faster than my rental Lime?" - you're asking "Which one will still feel like a great choice after 5.000 km of mixed commuting, weekend blasts, and the occasional ill-advised night ride in drizzle?"

Design & Build Quality

Put the Teverun and the Dualtron side by side and you can almost see the generational gap. The Fighter Supreme Ultra looks like it was designed in the same era as your smartphone: clean, integrated, everything flowing together, cables tucked away, and that big, bright TFT in the middle of the bars tying it all up.

The frame on the Teverun feels extremely cohesive. The one-piece forged neck and deck area give it that "single block of metal" sensation when you grab the stem and yank the wheel around. The carbon-look fenders are a bit of visual flair, but they're also solid and don't flap around like an afterthought. Buttons, switches, and the folding latch feel precise rather than "good enough". You notice it the first time you slam the stem upright and there's just... no play.

The Dualtron Storm New EY4, in contrast, looks very Dualtron: industrial, mechanical, purposeful, slightly brutal. Exposed aluminium, visible fasteners, chunky clamps. It absolutely feels strong - the chassis is classic Minimotors "built like a bridge" territory - but there's a faint whiff of legacy engineering upgraded over time rather than a holistic clean-sheet design. The new folding collar and double clamp are a big improvement over older Dualtrons, and once locked, the stem is reassuringly solid, but the whole scooter still feels a little more "machine shop" than "modern vehicle".

Build quality on both is high, but with a different flavour. The Storm EY4 is bombproof in the old-school sense, with a long track record of Dualtron frames surviving years of abuse. The Teverun, however, feels more refined out of the box: better integration, better cockpit execution, and fewer little rattles waiting to appear. In the hands, the Ultra comes across as the more modern, better thought-out product rather than simply the heavier-duty one.

Ride Comfort & Handling

This is where the philosophies really diverge.

The Fighter Supreme Ultra rides like a properly sorted modern performance scooter. The adjustable hydraulic KKE suspension has generous travel and, once dialled in, does a convincing impression of a small motorbike. Urban potholes, cobbles, bad tarmac - it shrugs most of it off. After a decent stint over broken city streets, my knees and wrists still felt fresh, which is not something I've often said after a long ride on stiff hyper-scooters.

Cornering on the Teverun is confidence-building. The wide deck and rear kickplate let you brace properly, and the steering damper it comes with as standard is a huge deal. Push it past city speeds and instead of that nervous twitch some high-power scooters get, the front end just tracks where you point it. Even at "I wouldn't admit this to my insurer" velocities, it stays composed rather than fidgety.

The Dualtron Storm New EY4 is more of a "sports suspension" experience. The rubber cartridge system is firm and can be tuned through multiple stiffness levels, but even on the softer side it never quite reaches the plushness of a good hydraulic setup. On smooth asphalt it's excellent - planted, precise, almost go-kart-like. On rough city edges, expansion joints and lumpy side streets, you feel much more of the surface. After a few kilometres of bad paving, your legs start doing more shock-absorber duty than on the Teverun.

Handling-wise, the updated, wider handlebars on the Storm are a massive improvement. High-speed stability is very good, and once you adjust to the firm suspension, it's razor-sharp. But without a standard steering damper, you're more reliant on rider input and grip strength to tame any hint of wobble at the top end. It's manageable - plenty of folks ride them flat-out - but the Teverun's damper-equipped front end is simply more relaxing to hustle.

In day-to-day reality, the Teverun is the one you'll happily ride across a whole city of questionable road maintenance without feeling punished. The Dualtron feels sportier and harder edged - rewarding on smooth roads, but less forgiving when the surface turns ugly.

Performance

Both scooters are hilariously, pointlessly fast for anything with a deck. You don't buy either because you "just need to keep up with traffic"; you buy them because you want the option to embarrass traffic.

The Fighter Supreme Ultra's dual motors deliver their power through sine wave controllers, and that changes the character of the whole machine. From a standstill, you can roll on gently and crawl at walking pace without any nervous twitch. Feed in more thumb and the scooter surges forward in a very controlled, very linear way - until you hit around city-limit speeds and it simply keeps pulling. It feels like there's always another gear waiting.

Crank it up into the higher modes and the Ultra goes from "quick" to "oh, hello adrenaline". Acceleration to illegal speeds is effortless, but crucially it still feels composed while doing it. There's none of that on/off, digital surge some older high-power scoots are known for; it's more like a big electric motorcycle - responsive but predictable.

The Dualtron Storm New EY4 plays a slightly different game. It has ferocious peak power and you feel it the moment you open the throttle. The older-style controller tuning gives it a more aggressive initial hit: the scooter leaps forward with that classic Dualtron punch. It's huge fun if you're used to it, slightly intimidating if you're not. Rolling acceleration is tremendous, and up to high-road speeds it has absolutely no trouble bullying cars out of the way.

At the top end, both are solidly into "don't do this without proper gear" territory. The Storm tends to feel more raw - exciting, a bit more demanding - while the Teverun feels a touch more refined and controlled as the speedo climbs.

Hill climbing? Neither of these scooters cares about your hills. The Fighter Supreme Ultra with its big current capability basically laughs at gradients - even heavier riders see it charge up long, steep climbs without sagging. The Storm EY4 is no slouch either, and its torque wallops you in the back when you point it uphill, but the Teverun's smoother delivery makes steep, twisty climbs less of a wrestling match.

Braking performance swings back toward the Teverun. Those 4-piston hydraulics with big rotors and well-tuned regen give you deeply reassuring stopping power and modulation. You can trail-brake into corners and scrub speed with two fingers, even from very silly velocities. The Storm's NUTT hydraulics and magnetic assist are strong and perfectly adequate, but they don't offer quite the same progressive, motorcycle-like feel as the Teverun's setup.

Battery & Range

This is the category where things stop being a contest and start being an execution.

The Fighter Supreme Ultra carries a battery that can fairly be described as ridiculous: a huge 72 V pack with a capacity normally reserved for boutique builds. In the real world, even riding quickly, you can do long cross-city trips and come home with a smugly healthy percentage left. Ride at more moderate speeds and you're in "charge it once, commute all week" territory. It genuinely rewires how you think about range; instead of planning your riding around the battery, you plan your battery around your life.

The Dualtron Storm New EY4's LG pack is high quality and offers genuinely good real-world range - plenty for long commutes and big weekend rides. But next to the Teverun's battery, it feels... normal. You'll still get a proper day's riding out of it, but the margin for "let's take a detour and see where this road goes" isn't as enormous. After a strongly spirited day, you're far more likely to be hunting for a socket.

Charging is the one place where the Dualtron claws back some ground. The Storm ships with a fast charger that brings it back to full in a single working day or a long evening, which is honestly how all big-battery scooters should be sold. The Teverun, with a single standard brick, takes its time. Using two chargers in parallel helps a lot, but that's either an extra purchase or extra kit to haul around. In daily life, though, the Ultra's battery is so big that most riders will charge less often anyway.

Range anxiety? On the Storm EY4 you'll think about it on mega days or if you're heavy on the throttle. On the Fighter Supreme Ultra, you almost forget the phrase exists.

Portability & Practicality

Let's be honest: neither of these is "portable" unless you routinely deadlift for fun.

The Fighter Supreme Ultra is heavy and long. You can fold the stem and wrestle it into a big car or a lift, but stairs are a fantasy unless you're part gorilla. The upside is that once it's parked, the scooter really does feel like a small motorbike substitute - big deck, solid stand, loads of presence. The folding mechanism is reassuringly stout and easy to operate, and there's no flex or drama once locked. Day-to-day, it's best if you have ground-floor storage, a garage, or at least an elevator.

The Dualtron Storm New EY4 is slightly lighter on paper, and in the real world they feel in the same "this is a vehicle, not a toy" weight class. Where the Storm wins big is the removable battery. If you live in a block of flats with a bike room downstairs and no socket, you can lock the chassis up and just haul the battery inside. It's not exactly a featherweight either, but it's far easier than trying to drag the whole scooter up stairs.

Folded, the Storm is a touch more compact thanks to its bar design, and the removable deck-battery option also makes transporting the frame alone a bit easier. But neither machine is something you roll into an office and tuck under a desk. They're both "lock it like a moped" propositions.

From a pure practicality standpoint: Teverun wins if your life is set up for a big scooter that you charge where it sleeps; Dualtron wins if you need the flexibility of carrying the energy indoors and leaving the bulk outside.

Safety

Safety at these speeds is a mix of hardware, stability, and how much the scooter helps you avoid doing something idiotic.

The Fighter Supreme Ultra comes loaded. Those 4-piston hydraulic brakes and strong regen give it stellar stopping performance. The factory steering damper is not just a nice-to-have; at hyperscooter speeds it's a real safety feature. It calms any tendency toward wobble and makes mid-corner bumps far less dramatic. The wide tubeless self-healing tyres add both grip and peace of mind - fewer punctures and a very planted feel in fast corners.

Lighting on the Teverun is properly serious. The main headlight actually lights the road instead of politely tickling it, and the 360° RGB strips that double as indicators and brake signals mean other road users can tell what you're doing rather than guessing. In bad weather, that matters more than any spec sheet ever will.

The Dualtron Storm New EY4 is no slouch either. The dual high-power headlights are a huge step up from older Dualtrons that basically required aftermarket lights. You get full signalling, bright RGB accent lighting, and good side visibility. Braking hardware is solid - hydraulic discs plus magnetic assist - and plenty of owners are perfectly happy bombing along at silly speeds on them.

Where the Storm lags is in the little touches. There's no stock steering damper, so high-speed stability relies more heavily on rider input and bar width. The suspension, being firmer, is less forgiving when you hit unexpected bumps fast. And the throttle tuning, while improved, is still a bit sharp at very low speed, which isn't ideal when you're threading through tight traffic or manoeuvring around pedestrians.

Both scooters can be ridden safely if you respect them, but the Teverun undeniably gives you a few more safety nets straight out of the box.

Price & Value

This is where things get interesting. The Fighter Supreme Ultra comes in noticeably cheaper than the Storm New EY4, yet brings a bigger battery, smoother controllers, 4-piston brakes, steering damper, self-healing tyres, and a very modern cockpit with smart features. In pure "hardware per Euro", it punches well above its price point.

The Dualtron Storm New EY4, meanwhile, sits firmly in "paying for the badge and the ecosystem" territory. You do get a removable LG pack, fast charger included, and the comfort of a huge parts and mod market. But if you strip away brand prestige and focus purely on measurable kit - battery size, braking hardware, suspension type, electronics - the Teverun offers more for less.

Long-term, the Storm holds value nicely because the Dualtron name is strong on the used market. The Teverun, being newer as a brand, still has some catching up to do on that front. Even so, given the lower initial outlay and higher spec, the Ultra looks like the more compelling purchase for most riders who prioritise actual riding experience over logo loyalty.

Service & Parts Availability

This is the one arena where Dualtron still feels like the safe, boringly sensible bet. Minimotors has been around for ages, and the Storm's parts - from tyres and brake pads to specific bolts and controller housings - are widely available, especially in Europe. Need a new swingarm or a replacement EY4 screen? Odds are your local dealer or at least an EU-based webshop has it.

Teverun's network is growing fast, and for a relatively young brand, they've made impressive strides. Common wear parts and even more serious components are increasingly easy to source through European distributors. But they don't yet have the same "you'll find spares for this five years from now in any big city" certainty that Dualtron enjoys.

If you're someone who racks up serious kilometres every year and likes knowing that any competent shop has seen your scooter before, the Storm EY4 still carries an advantage. If you're comfortable ordering parts online and wrenching a bit yourself, the Teverun is already in a good, improving place.

Final Verdict - Which Should You Choose?

Viewed purely as machines, both of these scooters are impressive. But when you ride them back to back and then look at what they cost, it's hard not to feel the Teverun Fighter Supreme Ultra quietly walking away with the win.

The Ultra gives you a massive battery, smoother and more civilised power delivery, a genuinely comfortable suspension, brilliant braking, serious lighting, and a very modern cockpit, all at a price that undercuts the Dualtron by a wide margin. It feels like a complete package - the kind of scooter where you don't immediately start making a list of upgrades you "really should" buy.

The Dualtron Storm New EY4 still has its strong arguments: the removable LG battery is a real lifesaver for flat-dwellers, the frame is tried and tested, and the Dualtron ecosystem of parts and community support is unmatched. If you're welded to the brand, or that modular battery is the key to making ownership viable, the Storm EY4 will absolutely deliver the performance and presence you're looking for.

But for the majority of riders who simply want the best ride, the best everyday experience, and the best return on their money, the Teverun Fighter Supreme Ultra is the scooter that feels like the future - while the Storm New EY4 feels more like a very fast, very capable past with a nice new screen.
