Four Wheels vs Dual Motors: ROADRUNNER RS5+ Takes On the MIA FOUR X2 (4x2) - Which Beast Actually Belongs Under Your Feet?

Fast Answer for Busy Riders ⚡ (TL;DR)

The MIA FOUR X2 (4x2) is the overall winner: it rides like a shrunken luxury ATV, feels bombproof, and delivers a level of stability, comfort, and confidence that the ROADRUNNER RS5+ simply cannot match, especially once speeds climb and the road gets ugly. If you want something that genuinely replaces a small motorbike and makes bad roads feel like a minor suggestion rather than a threat, the MIA is in a different league.

The ROADRUNNER RS5+ still makes sense if you want dual-motor punch, removable battery convenience and high performance at a much lower price, and you mostly ride decent tarmac with limited space or budget for a four-wheeled monster. Think "serious hot-rod scooter with some compromises" versus "over-engineered tank that just happens to lean."

If you care more about pure value per euro and traditional scooter feel, start with the RS5+. If you care about staying upright, arriving relaxed, and keeping your dentist out of the suspension conversation, keep reading about the MIA FOUR X2.

Stick around for the full breakdown - the devil, and the fun, are both in the details.

There are fast scooters, there are comfortable scooters, and then there's the slightly unhinged corner of the market where engineers are clearly having too much fun. That's exactly where the ROADRUNNER RS5+ and the MIA FOUR X2 (4x2) live - two very different answers to the question: "How far can we push electric micromobility before it stops being 'micro'?"

I've put serious kilometres on both: the RS5+ as a classic dual-motor, big-deck street blaster, and the MIA FOUR X2 as the strange, four-wheeled contraption you laugh at... until you ride it and start mentally listing which organs you could sell to afford one. One is trying to be the best do-it-all performance scooter for sane money; the other is trying to redefine what "safe" and "planted" even feel like on something you stand on.

If you're choosing between them, you're not asking "Is this faster than my old Xiaomi?" - you're asking which machine deserves space in your garage instead of a second car or motorbike. Let's sort out who each one really suits, and where the marketing claims survive a few hundred kilometres of reality.

Who Are These For, and Why Compare Them?

On paper, these two don't look like natural rivals: one is a fairly conventional dual-motor scooter with chunky suspension; the other is a tilting, four-wheeled, wide-stance UFO. But price and performance put them into a similar mental shopping basket.

The ROADRUNNER RS5+ sits in that "serious performance, still vaguely affordable" segment. It's for riders graduating from small commuters who now want real power, long range and grown-up components without entering hyper-scooter madness territory. Commuter during the week, hooligan on Sunday - that's the pitch.

The MIA FOUR X2 is more of a "statement vehicle." It costs like a high-end e-moto, and behaves like a compact, stand-up ATV with road manners. You buy this when you've decided your personal safety and comfort are not negotiable, and you're willing to pay handsomely to stop worrying about wet tram tracks and potholes.

They overlap on top speed, battery size, hill-climbing ability and the idea of being genuine car replacements for shorter urban and suburban trips. The difference is how they get there: the RS5+ leans on strong components and a clever removable battery; the MIA leans on physics, four huge tyres and some frankly extravagant suspension engineering.

Design & Build Quality

Pick up the RS5+ (figuratively; literally will strain your back) and it feels like a very solid, familiar big scooter. Thick aluminium frame, visible suspension hardware, wide deck with grippy tape, dark colours spiced with a few sporty accents. It gives off "serious kit" vibes - not delicate, not elegant, but robust in a slightly utilitarian way.

The folding mechanism is a chunky clamp arrangement. Once adjusted properly it feels secure, and the stock steering damper masks any small tolerance sins at speed. Cockpit layout is decent: central display, thumb throttle, hydraulics levers, everything where your hands expect it. Fit and finish is mostly good, though things like the fenders and kickstand remind you a bit where corners were trimmed to hit the price point.

Then you walk up to the MIA FOUR X2 and the RS5+ suddenly feels... normal. The MIA looks like someone shrunk a Dakar support vehicle. Exposed double wishbones, massive wheel arches, big-profile tyres, wide stance. Instead of a tube stem bolted to a deck, you've got a full quad chassis scaled down to human size. The materials - reinforced polymers, solid metal linkages, big hydraulic hardware - feel over-specced rather than just "sufficient."

Build quality on the MIA is on another tier. There's very little flex anywhere you don't expect it, and the tilting mechanism feels tightly engineered rather than clever-but-wobbly. Folded, it doesn't become small, but the way the stem and front assembly tuck down is impressively tidy for something with that much mechanical complexity. You can see where your money went - and why the RS5+ has to lean on value talk instead of outright refinement.

Ride Comfort & Handling

Let's start with the RS5+. On half-decent city streets, it's genuinely comfortable. The adjustable hydraulic shocks take the sting out of expansion joints and potholes, and you can tune them firmer for high-speed stability or softer for trail use. The 10-inch tubeless tyres add a nice, cushy first layer of damping. After a typical urban commute, your knees and wrists are fine, though rough cobbles will still make you work for it after a while.

Handling is classic big-scooter: you're on fairly narrow wheels, tall stem, plenty of power at both ends. It's agile enough, and the steering damper does a good job of calming high-speed twitchiness. You can lean it into bends with confidence as long as the road is predictable; pushing hard on sketchy surfaces, though, you're always a touch aware that you're one small contact patch away from a slide.

Now hop onto the MIA FOUR X2, and the contrast is borderline comical. Those 14,5-inch tyres don't "hit" holes so much as roll over them with a shrug. Combined with the double wishbone suspension, the X2 feels like it's hovering a few centimetres above the road. Cobblestones feel like mildly textured tarmac. Broken asphalt that had the RS5+ asking for mercy becomes "background noise."

The real surprise is how natural the handling feels despite the four wheels. The tilting system means you still lean like on a normal scooter, but the extra contact patches give you a ridiculous amount of mid-corner grip and forgiveness. You get away with sloppy lines the RS5+ would start complaining about. The MIA is less about darting agility and more about smooth, confident carving - you guide it rather than fight it.

On a long, ugly commute - raised tram lines, random holes, gravelly shortcuts - you step off the RS5+ thinking "That was fun, but I need a stretch." You step off the MIA thinking "I could easily go again." Comfort and composure are simply on a different level.

Performance

Both of these scoots are properly fast. The RS5+'s dual motors give you the familiar dual-motor launch: squeeze the thumb and it surges forward like an impatient dog on a leash. Off the line and up to city speeds it has more than enough punch to embarrass cars and spin the rear on dusty tarmac if you're ham-fisted. Hill starts are a non-event; it just goes, even with heavier riders.

The top-speed end of the RS5+ is lively. On open roads it keeps pulling well past the point where common sense suggests rolling off. Past that, the limiting factor isn't power but how much wind you can tolerate standing upright and how brave you feel on scooter-sized wheels. The brakes - proper hydraulic discs front and rear - match the power nicely and haul everything down hard without drama, as long as the surface is good and you keep weight low and back.

The MIA FOUR X2 plays in the same performance ballpark on paper, but delivers it very differently. The dual hub motors provide a deep, muscular shove rather than a nervous kick - torque comes in strong and sustained, especially on climbs. It doesn't quite have the raw "snap" off the line of some over-volted two-wheel hypers, but because the chassis stays so planted, you're comfortable using much more of what it has, much more of the time.

Top-speed cruising on the MIA feels oddly relaxed. The four-wheel footprint and longer wheelbase give it a planted, almost rail-like feel that the RS5+ can't match. Hard braking is where the physics really flex: you can brake late and hard without the rear getting light or the front wanting to tuck. It feels closer to a small ATV than a scooter in how it shrugs off emergency stops and sudden surface changes.

If you measure performance purely by how big your grin is when you close the throttle, both deliver. But if you include how confident you feel using that performance on bad roads or in rain, the MIA X2 steps ahead convincingly.

Battery & Range

Both scooters run serious battery packs with branded LG cells and claimed ranges that assume you ride like a saint on a diet. Ride them like actual humans - brisk pace, mixed terrain, some hills - and the picture changes, but stays respectable for both.

The RS5+'s deck-mounted pack gives you enough juice for a robust day of commuting with some detours, or a couple of days if you're gentle. Push hard in top power mode and you're still looking at a decent chunk of city real estate per charge. What really saves the day here is the removable battery: you can leave the muddy beast in a shed and take just the pack upstairs, or keep a second pack for those days when you decide your friend's house in the next town "isn't that far." The downside is charging is slow on the stock brick unless you invest in a second charger.

The MIA FOUR X2 uses a slightly higher-voltage pack of similar overall capacity. In the real world, range is in the same general region - enough for serious daily riding, especially if you're not full-throttle all the time. Despite four big tyres and more rolling resistance, the X2 doesn't bleed range as badly as you might expect, helped by efficient motors and smart controller tuning. Charging is notably quicker than the RS5+ on a per-Wh basis, and yes, the battery is also swappable - complete with that same "carry the pack, not the tank" lifestyle benefit.

Range anxiety? On either, not really. But the RS5+ stretches your euro a lot further per kilometre, whereas the MIA stretches your spine less. Priorities.

Portability & Practicality

Neither of these wants to be your fold-and-hop-on-the-train companion, but there are degrees of un-portability.

The RS5+ is heavy, but still within the realm of "I can grunt this into a car boot if I have to." The folding stem drops it into a reasonably compact lump, and with the battery removed the chassis becomes noticeably less brutal to move around. Wide bars and a long deck mean it still claims a fair bit of hallway or office space, but it's plausible as a keep-at-home-and-occasionally-car-transport machine.

The MIA FOUR X2 is from another planet here. It may only be a few kilos heavier on paper, but the wide stance and four-wheel layout make it feel more like moving a small kart than a scooter. Folded, it's low but still broad, so storage needs to be planned, not improvised. Carrying it up stairs is the stuff of gym memes unless you're built like a powerlifter. For garage or ground-floor owners with a decent-sized car, that's no big deal; for third-floor walk-ups, it's a deal-breaker.

In daily use, the RS5+ is easier to weave through narrow doorways, bike racks and tight bike lanes. The MIA, with its width, demands a bit more route and parking awareness. But once riding, the X2 makes up for it by being dramatically more practical over bad surfaces and in all weather, and the app features and accessory potential (racks, seat) push it further into "utility vehicle" territory.

Safety

Both brands actually seem to have thought about the fact humans are soft and tarmac is not, but they tackle safety from different directions.

The RS5+ leans on strong components: proper hydraulic disc brakes, a standard steering damper, decent lighting including indicators, and tubeless tyres that are less likely to pop catastrophically. At sane speeds, it feels secure and predictable. Push into its top end and you're relying heavily on that damper and your own balance skills - the basic physics of a tall, narrow scooter on small wheels still apply. A sudden pothole or slippery patch at high speed will always be "interesting."

The MIA FOUR X2, conversely, bakes safety into the geometry. Four wide-set tyres, long wheelbase, lowish deck: the platform simply doesn't get unsettled as easily. Hard braking stays composed, even if you grab a handful in a panic. Hit a small patch of gravel mid-corner and you usually feel a twitch rather than a full drama. Those big integrated lights and the sheer physical presence of the thing also make you far more visible in traffic - you look like a small vehicle, not an afterthought.

The tilting mechanism might sound like extra complexity, but it's actually a safety net: you still lean naturally into corners, so you're not fighting lateral forces like on a rigid quad, and the independent suspension keeps more rubber on the ground across rough surfaces. For riders with past crash trauma or weaker balance, the X2 is in another league of "I don't constantly feel like I'm about to die."

In short: the RS5+ is as safe as a fast two-wheeler reasonably can be. The MIA feels like it's playing a different, much more forgiving game.

Price & Value

This is where the RS5+ puts up its best fight. It sits in a price band that, for the kit you get, is undeniably strong value: dual motors, big branded-cell battery, hydraulic brakes, steering damper, decent lights, tunable suspension, removable pack - all standard. If you tried to match that spec from certain "prestige" brands, you'd usually spend more. Over several years, the swappable battery also extends the chassis life, which helps the long-term value case.

The MIA FOUR X2, by contrast, is unapologetically expensive. You're well into "luxury e-vehicle" money. But it's not smoke and mirrors: that price is paying for a unique chassis, a complex tilting quad suspension system, four massive tyres, and a level of mechanical over-engineering. Versus hyper-scooters from known big names, it actually doesn't look outrageous - you're just redirecting your budget from raw numbers to chassis sophistication and safety.

Objectively, euro-per-spec the RS5+ wins. Subjectively, euro-per-stress-reduced, the MIA often feels worth the stretch if you can afford it and you ride a lot. One is the rational upgrade; the other is the "I'm done compromising" purchase.

Service & Parts Availability

ROADRUNNER has built a genuinely solid reputation for post-sale support. Owners report quick parts shipments, responsive techs, and an overall sense that there are real humans behind the brand. For a scooter at this price, that matters a lot; it's one of the reasons people put up with the occasional fender rattle instead of jumping ship.

MIA Dynamics operates more in the boutique space, often via specialist distributors. Feedback from those channels is positive - issues like cosmetic shipping damage get sorted quickly, and technical questions don't just vanish into a ticketing black hole. But the ecosystem is naturally smaller: fewer total units sold, fewer DIY guides, fewer cheap pattern parts floating around online.

If you want maximum DIY-friendliness and a big English-speaking community, the RS5+ has an edge. If you're fine with a slightly more specialised ecosystem because you bought something fairly exotic in the first place, the MIA experience seems to live up to the premium aura.

Final Verdict - Which Should You Choose?

If I strip this down to riding reality, not spec sheets, the answer is surprisingly clear.

The ROADRUNNER RS5+ is a very capable, very fast, very practical big scooter for the money. If your roads are reasonably good, your budget is finite, and you want a muscular machine that can commute hard all week and play harder at the weekend, it does the job well. The removable battery is genuinely useful, the component choices are mostly on point, and with a bit of setup (and some fender fettling) it's a solid everyday weapon.

But the MIA FOUR X2 (4x2) feels like it's from the future. The stability, the way it ignores bad surfaces, the confidence it gives you at speeds where the RS5+ starts to feel like work - that matters far more in daily riding than one more tick on the spec sheet. It's kinder to your body, kinder to your nerves, and opens up routes and conditions that would make most two-wheelers tense. Yes, it's expensive and impractical for upstairs living, but as a ground-floor or garage-kept car replacement, it's an outrageously competent tool.

So: if your wallet or storage situation say "be sensible," the RS5+ is the smarter, more economical choice and will still put a big grin on your face. If you can stretch the budget and you really care about staying upright, staying comfortable and staying relaxed at speed, the MIA FOUR X2 is the scooter you'll still be talking about in ten years.

Based on the scoring, the MIA FOUR X2 (4x2) is our overall winner. In the end, the MIA FOUR X2 (4x2) just feels like the more complete machine: it calms the chaos of real-world roads, flatters your riding, and turns every grim commute into something you actually look forward to. The RS5+ fights back hard on price and gives you a lot of scooter for the money, but it never quite escapes the limitations of the traditional two-wheeled format in the way the MIA does. If I had to live with one of them for years, through winter potholes and late-night rides home in the rain, I'd take the MIA's planted, indulgent ride every time - and simply accept that my bank account would need a moment to recover.

That's our verdict when we try to stay objective – but hey, riding is mostly about emotions anyway, so pick the one that will make you look forward to your commute every single day.
