Fast Answer for Busy Riders ⚡ (TL;DR)
The NAMI Burn-E 3 is the overall winner here: it rides smoother, feels more composed on bad roads, and its ultra-refined power delivery makes brutal performance surprisingly easy to live with. If you care most about comfort, control, and "this feels like a proper vehicle, not a science experiment", the NAMI edges ahead.
The DUALTRON Thunder 2 EY4, though, hits back hard with even more ferocious acceleration, a gigantic real-world range, class-leading parts availability, and a bombproof reputation in the hyper-scooter world. If you want raw punch, proven durability, and a deep ecosystem of spares and upgrades, the Thunder 2 EY4 is your weapon.
In short: NAMI for ultimate ride quality and smooth sophistication, Thunder 2 EY4 for the hardest-hitting power tank with stellar support. Now let's dig in, because the details are where this duel really gets interesting.
Hyper-scooters used to be ridiculous fringe toys. Now they're very real car replacements, and two names are on everyone's lips: the DUALTRON Thunder 2 EY4 and the NAMI Burn-E 3. Both claim to be your "last scooter ever" - the endgame machine that renders further upgrades pointless, unless you develop an addiction to carbon fibre and anodised clamps.
I've put serious kilometres on both of these, from grim winter commutes to long, fast group rides. One of them feels like a cyberpunk missile built by a company that has been doing this forever. The other feels like someone listened to every rider complaint for the last five years and then systematically fixed all of them.
One-sentence snapshots? The Thunder 2 EY4 is for riders who want unapologetic, old-school Dualtron violence with a welcome dash of modern tech. The NAMI Burn-E 3 is for those who want superbike performance wrapped in limousine comfort. They're close rivals - but for different reasons - so keep reading before you throw several thousand euros at the wrong kind of crazy.
Who Are These For, and Why Compare Them?
Both scooters sit firmly in the "hyper" class: eye-watering speed potential, enormous batteries, dual motors, fully hydraulic brakes, and price tags that make rental scooters look like toys. You're not cross-shopping these with a city share scooter; you're cross-shopping with motorbikes and decent used cars.
The Thunder 2 EY4 comes from DUALTRON, the brand that practically wrote the rulebook on stupid-fast stand-up scooters. It's a logical upgrade path if you've already owned something fast and want more of everything - more power, more range, more road presence - in a platform with a huge global community and very mature parts support.
The NAMI Burn-E 3 is the disruptor. It aims at exactly the same rider: someone who's already "done" mid-range machines and now wants an uncompromising, daily-usable hyper-scooter. It competes directly with the Thunder 2 on speed, battery size and price, but leans heavily into suspension sophistication, chassis rigidity and controller smoothness.
They cost broadly the same, weigh roughly the same, go similarly insane speeds, and both are utterly overkill for beginners. That makes a direct comparison not only fair - it's necessary if you don't want to regret your choice later.
Design & Build Quality
Park these two side by side and you're basically looking at two different design philosophies.
The Thunder 2 EY4 keeps the classic Dualtron silhouette: chunky swingarms, a thick rectangular deck, and that unmistakable RGB light show along the stem and sides. It's very "urban tank from the near future". The frame feels dense, overbuilt and reassuringly heavy in the hands. The new EY4 display finally drags Dualtron's cockpit into the modern era: a big, bright colour screen front and centre, tidy backlit controls, and decent weather protection. The rubber deck mat is a small thing that makes a big improvement - grippy, easy to clean, and visually premium.
The NAMI Burn-E 3, on the other hand, is the naked exoskeleton supercar of scooters. The tubular, hand-welded aluminium frame looks purpose-built rather than sourced from a parts bin. The carbon fibre steering column not only looks the part, it genuinely reduces top-heavy feel. Cable routing and connector quality are excellent; little details like waterproof plugs and neatly loomed wiring show someone cared. The giant central display is more "bike dash" than scooter toy, with deep adjustability baked in.
In the hands, the Thunder 2 feels like a refined evolution of a proven platform: all the familiar Dualtron heft, but now with better finishing and fewer rough edges. The NAMI feels more like a clean-sheet "we're doing this properly" design - less flashy lighting, more serious structure.
Edge on pure structural engineering and cockpit sophistication? That goes to the NAMI. On overall sense of indestructible mass and brand-honed hardware, the Thunder 2 still absolutely holds its own.
Ride Comfort & Handling
This is where the philosophies diverge the most - and where many riders will make their decision.
The Thunder 2 EY4 uses Dualtron's familiar rubber cartridge suspension. Out of the box, it's firm. Think sports car, not sofa. On smooth tarmac, the scooter feels beautifully taut and connected, with minimal chassis movement even at utterly irresponsible speeds. Hit broken city asphalt or rough bike paths, and you start to feel more of the road than your knees would like over longer rides. You can tune it - swapping cartridges and adjusting arm angle - but it's still inherently a stiffer, more "performance first" setup.
The NAMI Burn-E 3 is at the other end of the comfort spectrum. Those fully adjustable hydraulic coil-overs give it what I can only describe as "magic carpet with teeth". You can dial in rebound and spring preload to match your weight and riding style. On cracked bike lanes, potholes, cobblestones - the NAMI simply smooths it all out. You feel the imperfections, but you're not being punched by them. After an hour on bad surfaces, I step off the NAMI feeling fresh. After the same on a stiffly-set Thunder 2, I'm definitely more aware of my spine.
Handling-wise, the Thunder's wide square-profile tyres and stiff suspension make it ultra-stable in a straight line and very planted at pace. Turn-in is deliberate rather than flickable; you lean and steer it with conviction rather than gentle intention. Great for high speed confidence, slightly less fun if you like dancing through tight S-bends.
The NAMI, with its pneumatic tyres and plush travel, feels more civilised but never vague. At sane speeds it's almost comically easy to ride: point, glide, grin. At silly speeds, that steering damper and rigid frame keep wobble largely at bay, while the suspension absorbs chatter that would unsettle harsher setups.
If your daily routes are mostly smooth and you like a firm, sporty feel, the Thunder 2 is genuinely satisfying. If you ride long distances or have to deal with neglected city infrastructure, the NAMI's comfort advantage is significant and very noticeable after a few dozen kilometres.
Performance
Both of these scooters accelerate in ways that will permanently recalibrate what you consider "quick". The difference is in how they deliver that violence.
The Thunder 2 EY4 is pure Dualtron heritage turned up to eleven. With enormous peak output and that "Overtake" party trick, full throttle feels like you've just been rear-ended by a car - voluntarily. The scooter squats on its rear tyre, the front lightens a touch, and your arms and core do real work keeping your body attached to the handlebars. It's intoxicating in a "I really shouldn't do that again... let's do that again" sort of way.
The flip side: at low speeds, especially in higher power modes, that trigger throttle can feel a bit binary. Small inputs can result in bigger surges than you intended, and tiptoeing through crowded areas takes finesse and patience. Once rolling, you can modulate it fine, but the first few millimetres of pull remind you there are overkill levels of current waiting in ambush.
The NAMI Burn-E 3 is just as fast in real-world terms but behaves very differently. Those sine-wave controllers are the secret sauce. Throttle response is creamy smooth: you can creep along at walking pace with absolute control, then roll on more and more power in a perfectly predictable curve. In full attack mode it still launches hard enough to surprise seasoned riders, but you always feel like you are in charge, not the firmware.
Hill climbing? Both laugh at gradients that make mid-range scooters cry. Heavier riders will particularly appreciate that neither machine feels winded on steep climbs - but the NAMI's smoothness and adjustability (front/rear power balance, regen levels) give it a small advantage in making that power actually usable on sketchy surfaces.
Top speed on both is deep into "this is a very bad idea on public roads" territory. The Thunder 2 has a slight edge on raw headline figures, but in practice, you'll usually back off long before either machine runs out of breath. What matters more is stability at fast cruising speeds, and here the NAMI's superb chassis and suspension tuning make it feel a touch more relaxed at the velocities most riders will actually use.
If you want the harder, more explosive hit - the drag racer feel - the Thunder 2 still delivers a more dramatic punch. If you want all the speed but with the composure of a well-sorted big motorcycle, the Burn-E 3 is the more mature performer.
Battery & Range
Both scooters are running big 72 V packs in the same ballpark of capacity, and both use branded cells. In other words: these are not budget batteries, and it shows.
The Thunder 2 EY4 is a range monster when ridden with any restraint at all. Even when you ride it like it's offended you personally, it holds up impressively. With mixed city use, bursts of WOT, and some hills, I can easily clock long day rides without constantly eyeing the voltage. Cruise at more sensible speeds and you enter "my legs gave up before the battery did" territory.
The NAMI Burn-E 3 is similarly generous. Its real-world range under spirited riding is slightly lower on paper, but in practice the difference isn't huge unless you're really pushing both back-to-back. The sine-wave controllers help sip power more efficiently when you're not constantly abusing the throttle, and the 72 V architecture keeps performance consistent deep into the pack.
Where there is a clearer difference is charging. The Thunder 2, on the included standard brick, takes ages from empty. Most owners simply never fully drain it and treat charging as an overnight affair, or they budget extra for beefy fast chargers and use the dual ports properly. Do that, and turnaround becomes perfectly acceptable, but it's an extra cost and a bit more fuss.
The NAMI's stock charging setup is more reasonable out of the box, and having twin ports plus widely available faster chargers makes it easier to integrate into heavy daily use. You're still filling a huge battery, but you don't feel like you've attached it to a phone charger from 2007.
Range anxiety on either of these? Only if you're planning very long, very fast group rides - and even then, planning your loops around a café with an outdoor socket solves most problems.
Portability & Practicality
Let's be blunt: neither of these is "portable" in the classic scooter sense. You don't fold them to hop on a tram; you fold them to fit them in a car or to roll them into a garage with a lower ceiling.
The Thunder 2 EY4 is brutally heavy. Lifting it into a car boot alone is something you feel in your lower back the next day. The folding mechanism itself is sturdy and gives a nice solid stem once clamped, but it isn't particularly quick or elegant. Once folded, it's long and dense - better than nothing, but not exactly IKEA-friendly.
The NAMI Burn-E 3 is in the same mass category - depending on battery spec, sometimes slightly more. Its folding clamp is serious and confidence-inspiring, but the scooter remains long and awkward, with wide fixed handlebars on many versions. One real-world annoyance: the stem doesn't latch to the deck when folded, so lifting it via the stem is a bit of a circus act unless you add your own strap or hook solution.
In terms of everyday practicality, think like a motorbike owner. Ground floor or garage storage? Both are fine. Have to drag something up three flights of stairs? Neither is remotely sensible. For short hops where you'd otherwise drive, both are superb: instant-on, no parking stress, and compact enough to tuck along a wall at home or work - provided that wall is on the ground floor.
The Thunder 2 gets extra practicality points for its massive parts ecosystem: if you ride hard and rack up kilometres, you will eventually need tyres, brake pads, maybe a new switch cluster. With a Dualtron, that stuff is easy to source. The NAMI is getting there quickly, but it's not yet as omnipresent as Dualtron in every local shop.
Safety
Both scooters take safety much more seriously than the "bolt-on brake and call it a day" approach of early fast scooters.
The Thunder 2 EY4 uses strong hydraulic discs with a positive, progressive lever feel. You can go from gentle speed shaving to full emergency anchor with one or two fingers, and the system matches the scooter's performance well. Electronic ABS is available; some riders love the added security on sketchy surfaces, others dislike the pulsing feel. The chassis itself is now far better behaved than early Dualtrons: the updated double-clamp stem feels solid at speed, and wobble is vastly reduced, though I'd still recommend a damper at the very top end.
Lighting on the Thunder 2 is plentiful. Side lighting and RGB make you very visible at night, and the raised rear light on the footrest area is much more in drivers' eyeline than deck-level LEDs. The downside is the relatively low-mounted front lights, which are fine for being seen but not world-class for seeing. Many riders add a bar-mounted auxiliary light for serious night runs.
The NAMI Burn-E 3 comes with an absurdly bright headlight by scooter standards - one of the few stock setups where I didn't immediately reach for an aftermarket option. It throws a proper beam down the road rather than a vague pool of light at your front tyre. Integrated turn signals and side lighting round out a package that's genuinely usable in traffic.
On the braking side, the NAMI's hydraulic system feels every bit as strong as the Thunder's, with some batches shipping with excellent multi-piston calipers. The big difference is chassis stability: that rigid welded frame, carbon column, and typically included damper (or at least ready mounts) mean high-speed stability feels less like "it's fine as long as I behave" and more like "this is what it was built for". Add the outstanding suspension, and you get more control over the contact patch on rough surfaces when braking hard.
Both are capable of doing very stupid speeds. Both demand proper gear and rider discipline. But out of the box, the NAMI offers the more confidence-inspiring lighting and chassis behaviour, while the Thunder 2 brings battle-tested hardware and an enormous community of riders who've already figured out all the safety upgrades you'll ever want.

Price & Value
Both scooters live in the same rarefied price air, with the NAMI typically a touch more expensive than the Thunder 2 EY4.
The Thunder 2 offers astonishing performance and a huge battery at a price that, while undeniably high, is actually quite aggressive for what you're getting. Add the mature parts pipeline and strong resale on the Dualtron name, and you have a machine that holds its value well and is easy to keep running far beyond the point where a cheaper scooter would have become a dusty garage ornament.
The NAMI asks slightly more but counters with an even more sophisticated ride, better stock lighting and controls, and that sine-wave controller goodness. For riders who value comfort and refinement as much as raw speed, the premium feels justified. For pure euros-per-brute-force, the Thunder 2 looks a bit sharper on paper.
Long term, neither is a budget choice - consumables disappear faster at high speeds, and you'll burn through tyres and pads more frequently if you ride them as intended. The Thunder's ecosystem can mean cheaper or more varied aftermarket options, while the NAMI gives you more "sorted from day one" hardware that doesn't scream for immediate upgrades.
Service & Parts Availability
This is one of the Thunder 2 EY4's ace cards. Dualtron has been around long enough that almost every major city with a scooter scene has a dealer or at least a specialist shop familiar with the platform. Need a new motor, swingarm, controller, or display two years from now? Odds are it's in stock somewhere in your country, if not in your city. There are also countless guides, videos, and forum posts covering every imaginable repair or mod.
NAMI is newer but expanding fast. The Burn-E series has built a fiercely loyal following, and distributors across Europe now carry spares and handle warranty. You might not find parts hanging on the wall of every generic scooter store yet, but if you buy through a reputable dealer, support is generally good and getting better every year. Community knowledge is catching up quickly too - there's already no shortage of owner groups sharing tuning files, maintenance tips and upgrade advice.
Overall, though, if you live somewhere with spotty niche-scooter support, the conservative choice is still the Dualtron, simply because of critical mass. You're buying into the most established hyper-scooter ecosystem out there.

Final Verdict - Which Should You Choose?
Choosing between the Dualtron Thunder 2 EY4 and the NAMI Burn-E 3 isn't about which one is "fast enough". They both cleared that bar several firmware versions ago. It's about character.
The Thunder 2 EY4 is the choice if you want that classic, slightly unhinged Dualtron punch backed by years of refinement and an absurdly good support network. It still feels like the reference hyper-scooter for sheer, unapologetic power and range in a platform that's been battle-tested all over the world. If your roads are reasonably smooth and you love the idea of a scooter that feels like a street-legal dragster, you will not regret picking the Thunder.
The NAMI Burn-E 3, though, is the one that most riders will enjoy more, more of the time. The suspension is kinder, the power delivery more civilised, the lighting better, and the chassis composure at speed genuinely impressive. It feels less like you're taming a beast and more like you're piloting a very fast, very well-sorted machine that happens to have a deck instead of a seat.
My advice: if you live for explosive launches, love the Dualtron brand ecosystem, and want the brawniest feeling scooter at this level, go Thunder 2 EY4. If you want something you can ride hard for hours, over bad roads, in varied conditions, and step off feeling like you could go again - the NAMI Burn-E 3 is the smarter, more rounded choice.

These metrics look purely at maths, not emotion. Price-per-Wh and price-per-km/h show how much you pay for stored energy and headline speed. Weight-related metrics tell you how much mass you're hauling around per unit of performance or range. Wh per km is a crude efficiency indicator. Power-to-speed and weight-to-power show how "overpowered" or strong each scooter is relative to its top speed and mass. Average charging speed is simply how quickly the battery can be refilled in watt terms - a useful figure if you do big daily mileage.
