Fast Answer for Busy Riders ⚡ (TL;DR)
The MIA FOUR X4 (4x4) is the overall winner here: it's more innovative, more versatile, and in real-world use it opens up terrain and situations where the Dualtron X2 UP simply cannot follow. If you want maximum stability, off-road capability, and a genuinely unique riding experience that feels closer to an electric ATV than a scooter, pick the MIA.
The Dualtron X2 UP still makes sense if you mainly ride long road stretches, crave that "magic carpet" highway feeling, and care more about ultra-long range on tarmac than exploring trails, gravel, and sand. It's a road missile and sofa on wheels, not an all-terrain tool.
If you're choosing your next serious machine, keep reading - the differences between these two are huge, and that's exactly why the comparison is so useful.
There are "big scooters", and then there are vehicles that make you question whether the word "scooter" still applies. The MIA FOUR X4 (4x4) and the Dualtron X2 UP both live in that second category. They're heavy, brutally fast, and expensive enough that you absolutely want to get this choice right.
I've put serious kilometres on both: forest fire roads, broken city edges, wet leaves, sketchy gravel, and the occasional "this was a terrible idea" steep hill. One of them behaves like an electric rally quad that just happens to fold; the other is a low-slung road cruiser that laughs at potholes but gets very grumpy if you treat it like an ATV.
If the MIA FOUR X4 is for people who look at terrain and think "I wonder what's at the top of that?", the Dualtron X2 UP is for riders who look at a long stretch of tarmac and think "I bet I can be there before the cars." Let's dive in and see which one actually fits your life.
Who Are These For, and Why Compare Them?
Both machines sit in the "hyper scooter" price bracket where you stop justifying them as toys and start thinking of them as vehicles. They target riders who are already past the rental-scooter phase and want serious performance, comfort, and range.
The MIA FOUR X4 is fundamentally an all-terrain platform: four wheels, all-wheel drive, tilting suspension, and a removable battery. It competes more with small ATVs and utility vehicles than with commuter scooters. Ideal for riders who split their time between dirt, gravel, grass, sand, and the occasional bit of asphalt connecting all that together.
The Dualtron X2 UP is a hyper-cruiser: enormous dual motors, a huge battery, and road-biased suspension and tyres. It's what you buy when you want to ride far and fast on roads and good paths, and you want to feel like you're standing on a flying carpet while doing it.
Why compare them? Because many riders on the market for a "do everything, no-compromise" top-tier scooter end up staring at exactly these two: one promises the best off-road and stability you can buy; the other promises the best road comfort and range. They cost car money. You only want to get that wrong once.
Design & Build Quality
In the flesh, the design philosophies couldn't be more different.
The MIA FOUR X4 looks like someone shrunk an off-road buggy and parked it in your garage. Four chunky all-terrain tyres, exposed double-wishbone arms, and a deck that feels like a structural part of a bridge. The tilting mechanism is the star: the whole chassis leans naturally into turns while the four contact patches stay planted. It's purposeful, industrial, and feels like it was engineered by people who spend weekends tuning rally cars, not browsing generic scooter catalogues.
Build quality reflects that approach: aerospace-grade aluminium everywhere, solid welds, and a complete absence of toy-like creaks. You can bounce on the deck, rock it side to side, and nothing complains. The folding architecture is cleverly executed; despite being a four-wheeler, it compresses down in height surprisingly well.
The Dualtron X2 UP goes for a different kind of intimidation. It's tall-stemmed, long, and massively overbuilt around a classic dual-motor scooter layout. Thick arms, thick stem, thick everything. It absolutely looks and feels like a tank, though a somewhat prettier one once the stem and deck LEDs light up. The chassis is stiff and confidence-inspiring, and Minimotors' latest frame revision has noticeably reduced the flex older X-series owners like to complain about.
Where the MIA feels like bespoke engineering, the Dualtron feels like a very polished evolution of a familiar platform. Both are solid; however, the MIA's unique chassis and tilting suspension give it an edge in perceived sophistication. It feels less like a heavy scooter, more like a compact electric vehicle.
Ride Comfort & Handling
This is where your riding environment really decides the winner.
On the MIA FOUR X4, comfort starts with the double-wishbone suspension at all four corners. Ride over roots, embedded rocks, or ugly cobblestones and you can literally watch the wheels dancing independently while the deck stays eerily calm. The tilting system lets you carve like on a big scooter or a snowboard, but with the security net of four big tyres underneath. On broken forest tracks, you just keep rolling while two-wheelers around you tiptoe or stop to pick their line.
Handling is almost comically confidence-inspiring off-road. Hit a sandy patch mid-corner that would normally send a Dualtron's front wheel sliding and the MIA just... keeps going. You feel the surface loosen, but there's no "oh no, I'm going down" moment. The trade-off is that the steering and tilt take a short adaptation period: your brain expects rigid quad behaviour, but what you get is something much more fluid.
The Dualtron X2 UP, by contrast, is all about silky smooth tarmac and rutted city streets. Those big hydraulic shocks and oversized road-biased tyres soak up potholes and speed bumps with a laziness that borders on smug. On asphalt, bike paths, and light gravel, it is one of the most comfortable things you can stand on. You float, you don't ride.
Handling, however, is clearly tuned for roads. The long wheelbase and steering damper keep it rock-solid at speed but make it less playful in tight turns. On rougher trails the sheer mass and two-wheel layout start to work against you: you have to manage slipping front tyre grip and shift your weight carefully, where the MIA just lets all four corners claw for traction and figure it out.
In short: if your daily mileage includes roots, sand, or rutted grass, the MIA's suspension and quad layout are on another level. If you mostly glide across dodgy urban infrastructure and decent tarmac, the X2 feels like first-class rail travel.
Performance
Both machines are hilariously overpowered by normal scooter standards. The flavour of that power is very different.
The MIA FOUR X4's quad-motor setup gives you that "pulled from four corners" sensation. Off the line, it hooks up instantly - no spin, just an almost tractor-like shove forward that you genuinely feel through your legs. On loose ground, the way all four tyres share the workload is the magic trick: on a steep, dusty climb where a Dualtron is scrabbling and throwing gravel, the MIA calmly digs in and tractors up with much less drama.
The throttle mapping out of the box is aggressive. At low speeds, a clumsy finger can turn a gentle nudge into a small catapult, especially in full 4x4 mode. Once you learn to be precise, the reward is a stunning ability to modulate traction on technical sections. Top-end speed is more than enough to be terrifying on dirt and more than adequate even for fast road sections. The main sensation is torque everywhere, rather than chasing insane top numbers.
The Dualtron X2 UP is a different beast: it feels like a muscular road bike with no fairing. Snap the throttle in full power and the scooter lunges forward so hard you instinctively lean into it. On clean tarmac, acceleration is savage, but also pleasantly controllable once you dial in your preferred power settings through the EY4 display and app. At sane speeds, it's actually smoother off the line than the MIA because the electronics and long chassis tame some of the violence.
Where the X2 really stretches its legs is high-speed cruising. Speeds that make normal scooters rattle, wobble, and scream are just a relaxed lope for the Dualtron. You reach a point where you're no longer "flat out on a scooter"; you're simply travelling quickly, and the machine feels composed and almost bored.
Hill climbing? Neither of these cares. The Dualtron shrugs off long, steep paved climbs like they're small bumps in the road. The MIA does the same but adds the ability to do it on mud, gravel, and ugly off-camber slopes where the X2's road-tyre front end starts to feel nervous.
Battery & Range
Both packs are big enough that you start thinking in "day trips" instead of "commutes", but again, context matters.
The MIA FOUR X4 carries a large removable deck battery stuffed with quality cells. Ride gently in two-motor mode on flattish ground and you can squeeze out very long distances, especially if you treat it more like a utility quad than a race toy. Use all four motors, climb, play in sand, and do repeated full-throttle bursts and the range drops, but still comfortably covers a long afternoon of genuine off-road fun.
The key here is flexibility: you can pop the battery out, take it indoors, or swap to a fresh pack if you're really chasing all-day excursions. This is a huge deal for people who can't or don't want to park next to a charging socket - or for professional use where the machine is expected to work all day, every day.
The Dualtron X2 UP's deck is basically one big battery box. Real-world mixed riding at respectable speeds still gets you very long one-charge days. If you're willing to knock the pace down and ride sensibly in Eco modes, you're in "charge every few days" territory for typical commuting. On range comfort, it's superb - you glance at the gauge far less often than on smaller machines.
The downside: that battery is fixed. Charging from low to full with a basic charger is an overnight-and-then-some affair. Using two stronger chargers makes it reasonable, but you're still planning charges, not opportunistically swapping packs. If you drain it completely and need to ride again soon, you're rearranging your life a bit.
Energy efficiency per Wh is better on the Dualtron, as you'd expect from a two-wheeler rolling on roads. The MIA pays an efficiency tax for its four contact patches and off-road tyres, but the removable battery partially compensates in the real world.
Portability & Practicality
Let's be blunt: neither of these is "portable" in the commuter-scooter sense. You're not slinging either over your shoulder and gliding up the stairs like a YouTube influencer.
The MIA FOUR X4 is heavy and wide, yet its folding geometry is cleverly executed. Folded, it squats down surprisingly low, and with the battery removed it becomes just about manageable for two people to lift into a large estate car or van. For suburban or rural owners with a garage and a car, this is a genuinely usable "drive to the trail, unload, explore, reload" machine. For people in a fourth-floor walk-up, it is a very firm no.
Where the MIA claws back practicality is in daily use. Four wheels and that stable stance make low-speed manoeuvres easy: turning tightly in a yard, creeping around obstacles, parking on uneven ground - it all feels natural. Add the ability to bolt on cargo racks or boxes and it turns into a little silent utility cart as easily as it becomes a weekend toy.
The Dualtron X2 UP is, simply, a massive scooter. Yes, it folds. No, that doesn't mean much. The folded package is long, tall, and heavy enough that even getting it into many car boots is a puzzle, and carrying it up stairs is a two-person deadlift with swearing. You really want ground-floor storage and somewhere you can roll it straight in.
On the flip side, for road-focused users, its practicality is in its simplicity: roll out of the garage, ride far, roll back, plug in. No batteries to remove, no mud-packed arms to hose off unless you insist on off-piste adventures. As long as your daily life is flat-access, it's very easy to live with. Just don't plan on casually hopping trains or dragging it into small lifts.
Safety
Both scooters take safety seriously, but they approach it from different angles.
The MIA FOUR X4's most underrated safety feature is simply: four tyres. On sketchy surfaces - wet leaves, slimy cobbles, loose gravel on a downhill - having four independent contact patches is worth more than another few hundred watts of motor power. You are vastly less likely to lose the front suddenly, which is how most painful scooter crashes start. The tilting system further reduces the risk of high-side style flips compared to a rigid quad layout.
Hydraulic disc brakes on both axles, with sizeable rotors, provide strong, predictable stopping even when you're loaded with gear. Because the chassis stays more level under braking than a two-wheeler, weight transfer feels more controlled, and you don't get that "I'm going over the bars" panic as easily. Lighting is comprehensive and sensibly positioned, with proper headlamps, tail and brake lights, plus indicators - a rare but hugely welcome inclusion for mixed-traffic riding.
The Dualtron X2 UP leans harder on traditional scooter safety tech: very strong hydraulic brakes with large rotors, backed up by magnetic braking and an ABS function to reduce skids on hard stops. Once you get used to the pulsing feel, that ABS can be a genuine saviour in the wet. The steering damper does heroic work keeping speed wobbles at bay when you hit bumps at road speeds that really should be reserved for vehicles with crash structures.
Its sheer size and weight contribute to stability at speed, but they're a double-edged sword: when things do go wrong, you're wrestling a lot of momentum. On wet or loose surfaces, you're still on two relatively narrow contact patches, so you must respect conditions more than on the MIA. Lighting is good, and the new display makes it easy to keep an eye on speed and modes, but visibility signalling (indicators) is more basic than the MIA's integrated road-style setup.
In mixed, real-world conditions - especially off-road or in bad weather - the MIA's platform simply gives you more passive safety margin. On clean tarmac, the X2's wide tyres, damper, and brakes are excellent, but they can't cheat physics on slippery surfaces the way four driven wheels can.

Price & Value
On paper, this looks easy: the Dualtron X2 UP costs far less than the MIA FOUR X4. If you're only doing a euro-per-Wh calculation, Dualtron wins by a comfortable margin.
But value isn't just battery capacity and motor figures. The MIA is a genuinely unique platform: four wheels, patented tilting suspension, removable pack, real off-road ability, and ATV-like stability. There's basically nothing else like it on the market. If that combination solves real problems for you - rough access roads, large properties, stability concerns, or specific work use - the price starts looking much more reasonable. You're not buying "a scooter with more power"; you're buying a different category of machine.
The Dualtron X2 UP, while far more common in layout, still offers very solid value in the road-cruiser world. For its price, you're getting a monstrous battery, proper hydraulic suspension, strong motors, and a proven brand with a big community and good resale. As a fast, comfortable road vehicle that can realistically replace many car trips, the cost can be justified relatively quickly if you actually rack up the kilometres.
If budget is tight and you mostly ride roads, the X2 is the more rational financial choice. If you specifically need (or deeply want) the four-wheel stability and off-road capability, the MIA's higher price buys something you simply won't get from a Dualtron, at any price.
Service & Parts Availability
Dualtron first: being one of the dominant premium brands worldwide has its perks. In Europe, you'll find multiple official or semi-official dealers, plenty of third-party parts, and a thriving ecosystem of mechanics who already know how to tear these apart. Consumables like brake pads and common bearings are easy to source, and even big-ticket items like controllers and motors are rarely unicorns - you might wait, but you'll usually get them.
The MIA FOUR X4, on the other hand, is more "boutique". The brand's support reputation is positive, but the network is leaner and more centralised. The platform itself is unique, so some parts are inevitably proprietary. You're not walking into any generic scooter shop and asking them to straighten a tilting quad arm. That said, the mechanical layout is logical and well-made, and if you're comfortable with basic tools and following documentation, a lot of maintenance is within reach for a mechanically minded owner.
For riders who want plug-and-play access to support and a big pool of fellow owners who've already had every possible problem, the Dualtron ecosystem is more comforting. For those okay with a slightly more "enthusiast" ownership experience in exchange for a unique machine, the MIA is still viable - just go in with realistic expectations about where and how you'll get it serviced.

Final Verdict - Which Should You Choose?
If you mostly ride on roads, bike paths, and relatively friendly surfaces, and you want absurd comfort plus enough range to make your car jealous, the Dualtron X2 UP is a very convincing choice. It's an outstanding long-distance cruiser, one of the most confidence-inspiring high-speed road scooters available, and it feels like a finished product from a mature ecosystem.
But if you value stability, versatility, and the freedom to ignore the words "end of road" on a sign, the MIA FOUR X4 (4x4) is on a completely different plane. It turns ugly terrain into playground, welcomes riders who are wary of two-wheel wobbles, and doubles as a genuinely useful utility platform. Its ride character is so distinctive that stepping back onto a conventional big scooter afterwards feels strangely limited.
Between the two, the MIA FOUR X4 is the more complete and future-proof machine for riders who want to do more than just go fast in straight lines. The Dualtron X2 UP remains a fantastic choice if your world is mostly tarmac and distance, but for sheer capability and grin-per-kilometre in varied conditions, the four-wheeled MIA walks away with it.
