Fast Answer for Busy Riders ⚡ (TL;DR)
If you want the most complete, modern hyper-scooter for real-world roads, the NAMI BURN-E 2 edges out as the overall winner thanks to its sublime suspension, rock-solid chassis, brilliant lighting and highly tunable, silky-smooth power delivery. It simply feels more sorted and more confidence-inspiring day after day.
The Dualtron Ultra 2 still absolutely earns its legendary status: it hits harder, goes further, and feels like a brutal off-road tank that just happens to do city speeds that make motorbikes nervous. If you ride more trails, crave raw punch and maximal range, or you want the proven Dualtron ecosystem, the Ultra 2 can be the better choice.
In short: NAMI for road comfort, refinement and wet-weather confidence; Dualtron for range, ruggedness and old-school, voltage-first insanity.
Now, if you want to know how they really feel back-to-back when the tarmac turns ugly and the road gets twisty, read on.
There's a moment the first time you leave a bike lane on one of these monsters, roll into open road and realise you're keeping pace with cars... while standing up. The Dualtron Ultra 2 and NAMI BURN-E 2 both live in that slightly unhinged corner of the scooter world where "commuter" quietly morphs into "motorcycle replacement".
I've put serious kilometres into both: long city commutes, late-night top-speed runs on closed roads, and enough hill climbs to annoy a small Swiss village. They take very different approaches to the same question: what should a no-compromise hyper-scooter feel like?
The Ultra 2 is the spiritual successor to the original off-road legend - a voltage hammer in scooter form. The BURN-E 2 is the young engineer's answer to everything people complained about in older designs - comfort, wobble, and lack of finesse. One is an armoured warhorse, the other a very fast flying carpet.
Let's put them head to head properly.
Who Are These For, and Why Compare Them?
These two sit in the same rarefied class: big 72-volt batteries, dual motors, serious brakes and price tags that will make your accountant raise an eyebrow. They're aimed at riders who are done with 40 km/h toys and want something that can realistically replace a car or motorbike for most urban and suburban trips.
Both target the same rider profile: experienced, gear-wearing adults who want brutal acceleration, long range, and high-speed stability - but not at the cost of build quality or safety. You wouldn't cross-shop either against a Xiaomi; you'd cross-shop them against each other, a Kaabo Wolf, or a petrol scooter.
They are competitors because they promise the same thing on paper: big power, big range, and big smiles. In practice, one is more trail-biased and old-school, the other more road-focused and modern. That's where it gets interesting.
Design & Build Quality
Park them side by side and you immediately see a clash of philosophies.
Dualtron Ultra 2 looks like a classic Dualtron: chunky, industrial, almost brutalist. Square-edged deck, massive swingarms, external bolts everywhere, rubber suspension blocks peeking out - it screams "function first, and that function is speed". The frame feels dense and overbuilt, the stem thick and reassuring. The rear "wing" doubles as both design signature and structural brace, and it feels solid when you hook your back foot against it.
Everything about it feels like it was designed by people who trust aluminium, steel and wattage more than software. The relocated controllers in the rear wing are a rare example of Dualtron subtlety: clever engineering disguised as a styling cue. In the hands, components feel robust rather than fancy. It's more tool than jewellery - in a good way.
NAMI BURN-E 2, by contrast, looks like it rolled in from a sci-fi film set. The hand-welded tubular frame around the deck gives it an exoskeleton vibe, the carbon-fibre steering column adds a hint of aerospace, and there's barely a piece of plastic in sight. The big, central waterproof display and clean cockpit layout instantly feel more modern than the typical Dualtron "bolt-on" look.
Where the Ultra 2's folding system feels like a heavy-duty clamp on a conventional stem, the BURN-E's main frame is essentially one solid piece, with the folding happening at a heavily braced neck. Grab the NAMI's bars and yank - there's this uncanny absence of flex or creak. It feels like a welded motorcycle front end that just happens to fold.
In the hands, the NAMI feels like a single, cohesive design; the Dualtron feels like a battle-tested platform that's been refined over generations. Both are extremely solid, but the NAMI wins on perceived sophistication and integration, while the Ultra 2 oozes old-school mechanical seriousness.
Ride Comfort & Handling
This is where their personalities really split.
Ultra 2 uses Dualtron's rubber cartridge suspension. At speed on decent tarmac, it feels reassuringly firm and planted, almost like a sport bike on stiff settings. Hit gentle waves in the asphalt and the chassis just rides through without drama. Take it into hard-pack dirt or gravel and the combo of stiff suspension and big, fat tyres gives you a surprisingly controlled, rally-car feel.
But roll slowly over broken city pavements, cobbles or sharp-edged potholes, and the Ultra's firmness starts to show. Lighter riders especially will feel a lot coming through the deck; after a few kilometres of nasty sidewalks, your knees know you've been out. You can tune stiffness with different cartridges, but the fundamental character leans towards stability over plushness.
BURN-E 2 is the polar opposite. Those long, adjustable hydraulic shocks transform the experience. On bumpy city streets it genuinely feels like the scooter is doing the suffering for you. You roll over manhole covers and small potholes that would make an Ultra 2 thud and the NAMI just goes "was that something?". On long rides, the difference is huge: you arrive fresher, shoulders looser, legs less tense.
In corners, the NAMI's suspension and rigid chassis combine for a very confidence-inspiring feel. You can lean it over on good tyres like a big, stable longboard with engines. The Ultra 2 also corners well once you trust it, especially with the wider handlebar versions, but it communicates more of what the road is doing. Some will call that "feedback", others will call it "a bit harsh".
If your daily environment includes rough asphalt, patched bike lanes and the occasional pothole ambush, the NAMI is simply kinder to your spine. If you prioritise a firmer, more connected feel and do more high-speed straight-line or trail riding, the Ultra 2 still holds its own.
Performance
Both will happily rip your arms off if you're sloppy with the throttle, but how they do it is very different.
Ultra 2 is the classic Dualtron experience turned up: brutal, immediate, and oddly addictive. In full dual-motor turbo mode, the scooter lunges forward the moment you ask. If you're not leaning over the bars, the front end feels light enough that you instinctively shift your weight forward. It has that "freight train that just woke up angry" character - relentless pull that keeps going well past the speeds you should reasonably be doing on anything with a deck.
At high speeds it sits in that sweet spot where the chassis feels calm and the motors are loafing. You cruise at speeds that would terrify rental scooter riders, yet the Ultra is just idling in its comfort zone. Hill climbs are almost comical: on long, steep grades where mid-tier scooters start gasping, the Ultra 2 just keeps pulling like the hill's not there.
BURN-E 2 doesn't smack you in the chest quite as violently from a standstill; instead it feels smoother and more controllable from the first centimetre of throttle. Those sine-wave controllers allow you to creep along at walking pace with surgical precision, then roll on progressively into serious acceleration. It's still very, very quick - just more polite about how it gets there.
On open road, the NAMI winds up to its top-end in a beautifully linear way. You don't get that slightly ragged, square-wave surge some older performance scooters have; it's more like an electric motorbike: twist, pull, grin. It doesn't quite match the Ultra 2's absolutely wild upper-range kick, but in the speeds where most sane people spend their time, it feels more predictable and confidence-inspiring.
Braking performance is excellent on both, but again with a different flavour. The Ultra's hydraulic discs plus electronic ABS give strong, sharp stopping power, with the familiar Dualtron pulsing under hard E-ABS use. The BURN-E's Logan hydraulics paired with powerful adjustable regen feel more "one-piece": you roll off the throttle and the scooter starts slowing with real intent, often enough that you barely touch the levers except in emergencies.
If your idea of fun is absolutely maximum, slightly unhinged straight-line fireworks, the Ultra 2 still feels more savage. If you want power that's easier to meter out in town and less likely to catch you out mid-corner, the NAMI has the edge in real-world usability.
Battery & Range
Both scooters sit firmly in the "you'll get bored before they get tired" category, but they play the game differently.
Ultra 2 packs a bigger battery. In gentle eco riding, the claimed range is absurdly long; in the real world, blasting around in dual motor and doing "why am I like this" acceleration runs, you can still cover a long day's ride without anxiety. Even ridden hard, you can crush commutes that would make typical commuter scooters weep, then detour home via the scenic route just because you can.
The 72-volt system also helps it stay punchy deep into the pack: you don't feel that depressing "oh, it's tired now" drop-off as early as with many 60-volt machines. The flip side is charging: with the standard trickle charger, a full empty-to-full top-up is an overnight-and-then-some affair unless you invest in faster chargers and use both ports.
BURN-E 2 runs a slightly smaller pack but still plenty for almost anyone's day. Treat the throttle with some respect and it will do big urban loops or long commutes comfortably. Ride like every green light is a drag race and you'll still get enough distance that you're not hunting for sockets at lunchtime.
Because the battery is smaller than the Ultra's, charging is a bit more civilised. Using both ports and faster chargers, an empty battery can be turned around in a reasonable evening rather than "leave it for a full day and hope". For riders who do daily mid-length commutes rather than extreme touring, the NAMI's pack feels very well judged.
So: Ultra 2 for people who genuinely need or simply want extravagant range and don't mind planning charging (and maybe buying a fast charger). NAMI for people whose riding pattern is long, but not expedition-long, and who appreciate shorter charge cycles.
Portability & Practicality
Let's be honest: neither of these is hopping onto a train with you unless you moonlight as a strongman.
Ultra 2 is heavy but just about on the edge of "one-person deadlift into car boot" territory for a reasonably fit adult. The classic Dualtron fold - stem down, deck long - fits into many car boots or the back of an estate car, but it's not small, and you will swear the first few times you lift it. Stairs? Doable for short flights, miserable beyond that.
On the plus side, the straight-edged deck and relatively compact height when folded make it slightly less awkward to store in a hallway or against a garage wall. You do need to respect its bulk though; this is not something you casually drag into a café.
BURN-E 2 is even more of a handful. The weight is similar or a touch higher, but the frame is longer, the stem taller and the handlebars very wide. Folded, it's more "electrical surfboard with opinions" than compact package. Lifting it into a car is a two-hand, think-about-your-back event, and some smaller boots simply won't accept it without playing Tetris.
Where the NAMI claws back practicality points is weather resistance and daily usability. That IP rating means you're much less stressed when the sky suddenly decides to test you. The big, actually-useful headlight and clear turn signals make night and mixed-traffic riding feel less like a gamble. The horn sounds like it belongs on a small motorbike, which is exactly what you want when a driver starts drifting into your lane.
In everyday use: Ultra 2 is marginally easier to stash and manhandle; BURN-E 2 is less compact but more truly "ride in any weather, at any hour" practical.
Safety
Both scooters are fast enough that safety stops being a spec sheet item and becomes an existential question.
Chassis & stability: The NAMI's rigid, one-piece frame and carbon stem combo is a huge plus. There's essentially no stem play, and the geometry feels very assured at speed - especially once you add a steering damper, which many riders consider mandatory for truly high-speed runs. The Ultra 2's stem can feel rock solid when properly clamped and maintained, but the traditional Dualtron clamp design does require periodic attention to keep creaks and micro-wobbles at bay.
Brakes: Both come with proper hydraulic discs and strong electronic braking. Stopping power is more than adequate on each, but the BURN-E's regen tuning lets you treat the throttle like a brake lever in many situations, which helps keep the scooter composure intact - especially downhill. The Ultra's E-ABS is very effective but has that on-off pulsing character that some riders dislike.
Lighting: Here the NAMI wins by a country mile. Its bar-height headlight actually lights the road; you can ride at speed at night without feeling like you're guessing what's under your front wheel. The deck LEDs and proper indicators make you more visible and more communicative in traffic. The Ultra 2's stem and deck lights look cool and help you be seen, but for seeing ahead at speed you'll almost certainly end up strapping an aftermarket light to the bars.
Wet conditions: NAMI's water resistance gives it a clear edge if you ever ride in the rain. With the Ultra, you're basically in "take it easy and hope you don't hit electrics or knobbly-tyre slip" territory. With the NAMI, you still need to respect the wet, but you're not constantly wondering what the water's doing inside your scooter.
Ridden with proper gear and a sensible brain, both can be safe enough. The NAMI just stacks the deck in your favour more consistently.

Price & Value
Both live in the "serious purchase" end of the spectrum, where you could also be shopping for a used 125 cc motorbike.
Ultra 2 asks you to pay a little extra for the Dualtron name, the massive battery options, and the long-established ecosystem. You're buying into a platform with a huge aftermarket, lots of community knowledge, and very good resale value. If you plan to rack up thousands of kilometres, tune, tinker and maybe eventually sell on, that matters.
BURN-E 2 undercuts many equivalently serious 72-volt rivals while including features they often make you pay extra for: excellent suspension, a proper headlight, and advanced controllers. You're not getting the absolutely enormous battery of some rivals, but you're getting a more complete "out of the box" package. You don't immediately feel like you need to spend extra on lights, suspension tweaks or waterproofing.
In raw "what you feel per euro" terms, the NAMI edges it. In long-term "platform maturity and parts everywhere" terms, the Ultra 2 makes a compelling case. It really comes down to whether you value refinement and advanced engineering more than sheer battery capacity and brand legacy.
Service & Parts Availability
Dualtron is the veteran here. Europe is full of dealers, independent shops, and unofficial Dualtron whisperers who can strip and rebuild one in their sleep. Motors, swingarms, controllers, stems, aftermarket everything - it's all out there. If you like the idea of running the same scooter for years, doing your own maintenance or upgrades, this ubiquity is a big plus.
NAMI is newer but quickly building support. Official distributors across Europe carry spares and the brand has a good reputation for listening and sending improved parts when issues crop up. You won't find "NAMI parts" in every small shop the way you might find Dualtron bits, but for a premium brand they're doing a much better job than most younger names.
If you live somewhere with a strong Dualtron dealer network, the Ultra 2 has the edge for convenience. If you buy through a solid NAMI distributor, you're far from unsupported - it's just a younger ecosystem.

Final Verdict - Which Should You Choose?
In back-to-back riding, the pattern is clear: for most riders on real roads, the NAMI BURN-E 2 feels like the more complete, modern package. It rides softer, tracks straighter, lights your way better and shrugs off bad weather more confidently. Its smooth throttle and deep customisation make it easier to live with, especially if you share roads with traffic and your routes include broken asphalt or long commutes.
The Dualtron Ultra 2 fights back hard with more brutal top-end performance, larger battery options and a bombproof, proven platform. If your rides are longer, faster, or more off-road flavoured - or you simply like the idea of a scooter that feels like a grumpy rally car on two electric hubs - the Ultra 2 remains a fantastic, genuinely exciting choice. It also makes a lot of sense if you value Dualtron's sprawling parts ecosystem and established reputation.
So, choose the NAMI BURN-E 2 if you want the best-feeling ride, the best suspension, and a scooter that feels like a refined electric vehicle rather than a hot-rodded toy. Choose the Dualtron Ultra 2 if range and raw punch matter more than plushness, you occasionally hit dirt trails, and you like your scooter with a bit of old-school Dualtron attitude.
