Quad Tank vs. Voltage Rocket: MIA FOUR X2 (4x2) Takes on the INMOTION RS JET

Fast Answer for Busy Riders ⚡ (TL;DR)

The MIA FOUR X2 (4x2) is the more complete, confidence-inspiring machine here: it rides softer, feels safer, and turns nasty roads into something you actually look forward to. If you want car-like stability, "floating" comfort and a scooter that practically dares potholes to do their worst, this is your winner.

The INMOTION RS JET fights back with raw value and classic dual-motor excitement: it's lighter in feel, brutally quick for the money, and ideal if you want a conventional high-performance scooter that goes like a rocket on tarmac.

Choose the MIA if you care most about safety, comfort and everyday serenity; choose the RS JET if you're chasing 72V thrills at a relatively sane price and mostly ride good roads. Now, let's dig into why these two feel so different once the wheels start turning.

Keep reading-the real story is in how they ride, not just what's on the spec sheet.

Who Are These For, and Why Compare Them?

On paper, the MIA FOUR X2 (4x2) and the INMOTION RS JET don't look like obvious rivals. One is a tilting four-wheeler that looks like it escaped from a lunar base; the other is a classic dual-motor, two-wheeled hyper-commuter with a sci-fi twist. Yet they actually sit in a similar performance band: serious power, serious weight, and aimed at people who are done with toy scooters.

The RS JET lives in the "affordable 72V" performance segment-a missile for riders wanting big torque and high speed without jumping into the most expensive exotica. The MIA FOUR X2, by contrast, is a premium machine through and through, priced like a small motorcycle and engineered like a tiny off-road racer that just happens to fold.

So why compare them? Because for many riders the question isn't "which architecture?" but "what will make my life better: extreme stability and comfort, or extreme bang-for-buck speed?" Both can replace a car for many trips. Both demand respect. But they deliver very different experiences on the same roads.

Design & Build Quality

Pick up (or rather, try to pick up) the MIA FOUR X2 and the first thing that hits you is that this isn't a scooter, it's a piece of machinery. Double wishbone arms on each corner, huge tyres, an exposed, purposeful chassis-more Dakar buggy than rental Lime. Everything feels overbuilt: the stem has none of that vague flex you find on many big scooters, the deck is broad and reassuring underfoot, and the visible suspension components scream "I'm here to work, not just look pretty."

The RS JET feels more familiar: a stout aluminium frame, clean cable routing, and that bold black-and-yellow "I'm fast, please respect me" paint. Build quality is solid and tight-no obvious rattles, no toy-like plastics. You can feel that it's derived from a more expensive flagship: the chassis feels like it was designed to handle more power and more battery than this model actually carries, which is never a bad thing for longevity.

Where they diverge is philosophy. The MIA is clearly engineered from the ground up around geometry and safety-four contact patches, tilting mechanism, independent suspension. Range, power and even speed feel almost secondary to staying stuck to the ground. The RS JET, on the other hand, is a classic hot-rod approach: big voltage, strong motors, sophisticated control electronics and a surprisingly premium cockpit (that glorious touchscreen) wrapped in a tough, but conventional, two-wheeled package.

In the hands, the MIA feels like a boutique, low-volume engineering project refined to a high standard. The RS JET feels like a mass-market product done unusually well. Both are solid; the MIA just lands on a clearly higher rung of "mechanical art."

Ride Comfort & Handling

This is where the MIA FOUR X2 quietly (well, not that quietly) walks away from almost anything on two wheels.

On the MIA, you stand on a wide, stable deck over four big tyres and a proper double-wishbone suspension at each end. Roll out onto broken city asphalt, cobblestones, or that special kind of municipal neglect that passes for a bike lane in many European cities, and the scooter just... floats. You see the bumps. You hear them. But your knees and spine get a heavily filtered version of events. After a long loop through rough backstreets and gravel paths, I stepped off feeling like I'd been gliding, not fighting the road.

Crucially, the handling matches the comfort. The tilting mechanism means you carve it like a normal scooter-lean in, and the chassis elegantly follows-yet the four wheels keep it composed when one side hits something nasty mid-corner. You don't get that heart-stopping twitch you sometimes feel on powerful two-wheelers when a single tyre skips on gravel.

The RS JET rides well for a traditional performance scooter. Its adjustable suspension can be dialled from pleasantly supple to firm and sporty. On decent tarmac and moderate bumps, it's genuinely comfortable, and the wide 11-inch tyres do a good job of smoothing the edges. After a typical suburban commute of a few dozen kilometres with a mix of road surfaces, I got off the JET feeling fresh, not battered.

But when you put both back-to-back on terrible surfaces, the difference is obvious. On the RS JET, long stretches of broken pavement and repeated sharp hits start to creep up your legs-even with the suspension softened, you're still balancing a tall two-wheeler that communicates every bigger pothole directly to your body. On the MIA, those same sections feel like a slightly bouncy carpet. If your city is more "post-apocalyptic" than "smooth boulevard," the choice is very simple.

In tight, technical manoeuvres, the RS JET feels narrower and more conventional-easier to thread through narrow gaps and classic bike lanes. The MIA's extra width needs a bit more spatial awareness. But in terms of sheer stability and ease of staying relaxed, especially at low speeds and over sketchy surfaces, the MIA is in a different league.

Performance

Let's be honest: neither of these scooters is slow. Both will do speeds that belong more in the motorcycle lane than the toy section.

The INMOTION RS JET delivers its performance with the attitude you'd expect from a 72V system. Twist the thumb, and it lunges forward with a very linear, very insistent shove. Getting from city speeds up to "are you sure this is a good idea?" happens alarmingly quickly; you need a good stance and your weight planted properly on the deck. It has that delicious, turbine-like build of speed that never really feels like it's running out of breath until common sense-or the road-runs out first.

Hill starts? It barely registers them. You point it up a steep street and it just keeps pulling, with only your courage and the state of the road deciding when to back off. The sine-wave controllers give you a refined feel: slow manoeuvring is surprisingly smooth for such a powerful scooter, then as you switch into sport modes, the leash gets shorter and the grin gets wider.

The MIA FOUR X2 takes a slightly different approach. It has more than enough power to catapult you well beyond standard city speeds, but it doesn't try to impress you with violence. The acceleration is strong, but the combination of four-wheel drive on the rear axle and a very planted stance makes it feel more like being shoved by a small car than yanked by a motorbike. You get a strong, confident surge rather than a nervous snap.

Where the MIA really shines is that you can actually use its performance more of the time. On a sketchy, wavy backroad or a tram-track-crossed boulevard, you think twice before unleashing everything on a tall two-wheeler, simply because you know what happens if that front wheel skips. On the MIA, you're far more willing to keep the pace high, because the chassis never feels like it's going to punish you for an imperfect patch of asphalt.

Braking performance is excellent on both, but again the feel differs. The RS JET's full hydraulic system with large rotors offers strong, progressive stopping, but when you're hard on the brakes at speed, you're still balancing a lot of mass on two tyres. On the MIA, slamming the levers feels almost unfair: the four-wheel footprint and low, long stance give you a level of braking confidence that borders on smugness. Emergency stops feel controlled rather than dramatic.

Battery & Range

Battery anxiety plays out differently on these two.

The RS JET packs a high-voltage battery that, on paper, promises impressive range. In the real world, ridden the way this scooter begs to be ridden-strong acceleration, brisk cruising-you're realistically looking at a good half-day of hard use or a generous commuting loop before you need a wall socket. It's absolutely adequate for most riders, but if you're a heavy throttle addict, you'll see that gauge moving faster than the brochure suggests.

The MIA FOUR X2 runs a large-capacity pack built from quality cells, and in real life delivers a similar "useful" distance: a solid chunk of urban riding, or a long mixed-surface adventure, on a single charge. The key difference is psychological: the MIA's swappable battery completely changes how you think about range. You finish your ride, pop the pack out, and carry it indoors like a briefcase. If you own a second battery, range ceases to be a hard limit and becomes a question of how many packs you're willing to own.

Charging is another contrast. The RS JET's big 72V pack takes its time on a single charger; with dual chargers you can bring it into a reasonable overnight/long-evening window, but you still need the scooter parked near power. The MIA's removable pack means the scooter can live in a garage, shed or car boot while the battery charges upstairs. In daily life, that's a much bigger quality-of-life advantage than a theoretical few kilometres of extra range either way.

Portability & Practicality

Let's be blunt: both are heavy machines. If your dream is to sling your scooter over one shoulder and dash up three flights of stairs, you're reading the wrong comparison.

The RS JET is, in theory, the more portable of the two. It folds into a compact footprint and isn't outrageously wide, so it's easier to park in a hallway or wedge into a car boot. In practice, the one glaring annoyance is that the stem doesn't latch to the deck when folded. Carrying it means wrestling with a swinging front end unless you add your own strap or technique. For short shuffles-lifting into a car, moving it around a garage-it's doable but not delightful.

The MIA FOUR X2 folds in height rather than footprint: the stem comes down, but you still have that glorious quad stance and big tyres. This is a scooter that expects a ground-floor home or a lift. Lifting it solo is a workout; lifting it up any serious stairs is a life choice. Where the MIA claws back practicality is with that removable battery. You never have to drag the whole muddy beast inside just to charge it, which, if you live in an apartment, is worth its weight in... well, in not ruining your floors.

Day to day, both work well as car replacements: quick runs to the shop, commuting across town, or joyrides out of the city. The RS JET's narrower stance makes it friendlier in narrow bike lanes and tighter urban clutter. The MIA occupies a bit more of the lane and feels more "vehicle-like"-which, depending on your city's traffic culture, can actually be an advantage for being seen and taken seriously.

Safety

Safety is where the MIA FOUR X2 quietly justifies its price tag.

Four wheels on the ground radically change the risk profile. On slippery paint, wet leaves, gravel, or those charming polished tram tracks, the MIA gives you redundant grip; even if one wheel momentarily misbehaves, the others keep things pointed in roughly the right direction. That translates directly into fewer "oh no" moments-especially for less experienced riders, heavier riders, or anyone who simply doesn't want to gamble their collarbones on every autumn commute.

Combine that with huge tyres, very serious hydraulic brakes, and a low, long chassis that doesn't like to pitch forward, and emergency braking becomes far less dramatic than most scooters in this power class. The MIA's lighting is bright and its physical width makes you visually more substantial in traffic, which drivers tend to respect more than a slender vertical line.

The RS JET does a commendable job in the safety department for a high-performance two-wheeler. Hydraulic brakes are powerful and well-modulated, the 11-inch tyres offer strong grip on tarmac, and the adjustable geometry lets you lower the ride height to reduce speed wobble potential. Add in proper lighting, including turn signals, and a serious water-resistance rating, and you've got one of the safer "rocket scooters" around.

But physics doesn't care about marketing. Two contact patches versus four is a fundamental difference. The RS JET can be ridden safely-and many do-but it demands more concentration and rider skill, especially at higher speeds and in bad conditions. The MIA, by design, bakes in more margin for human error.

Price & Value

The RS JET is, unquestionably, a value monster. For what you pay, you get proper 72V performance, dual motors, quality suspension and brakes, and one of the best displays in the game. If your main goal is to experience "big boy scooter" performance without jumping into car-money territory, this is one of the smartest buys on the market.

The MIA FOUR X2 is the opposite: it asks for a serious financial commitment. But what you're paying for is not just wattage and watt-hours. You're buying a unique four-wheel, tilting, double-wishbone platform that simply doesn't exist elsewhere in this category. You're effectively purchasing a safety system, a comfort experience, and a longevity promise that go beyond spec sheet comparisons.

So, which is better value? If your metric is euros per unit of speed, the RS JET wins easily. If you factor in stability, comfort, ride quality and the kind of peace of mind that keeps you from dreading winter commutes, the MIA earns its stripes. In other words: the RS JET is cheaper; the MIA is better value if you actually use it hard and long term.

Service & Parts Availability

Inmotion has a growing global footprint. Parts for the RS JET-tyres, brake components, electronics-are increasingly easy to source through European distributors and specialist shops. Turnaround times aren't always instant, but for a performance Chinese brand, support is comparatively decent, and the community knowledge base is large and active.

MIA Dynamics is more niche, but that's not automatically a downside. The MIA FOUR platform is built with service in mind: exposed components, accessible cabling, and a design that doesn't hide everything under a plastic shell. Feedback about support from their partners has been strong, with owners reporting responsive help and good will on issues like shipping damage. Parts are more specialised, yes, but they're not disposable rental-scooter parts either; you're dealing with a smaller ecosystem, but one that treats the scooter as a long-term product rather than a consumable.

For quick off-the-shelf bits, the RS JET has an edge. For deeper, serious ownership where you're willing to maintain a premium machine, the MIA doesn't leave you stranded, and the platform's robustness means you'll likely be maintaining less often.

Final Verdict - Which Should You Choose?

Between these two, the MIA FOUR X2 (4x2) is the scooter I'd put in my own garage if money and stairs were not an issue. It simply redefines what "safe and comfortable" can mean at this level of performance. If you ride daily on bad roads, if you've ever had a close call on a twitchy front wheel, or if you simply want a machine that feels like it's on your side even when conditions are not, the MIA is the stronger, more confidence-inspiring choice.

The INMOTION RS JET is still a very good scooter-especially for the price. If your roads are reasonably smooth, you want traditional two-wheel dynamics, and you're chasing that 72V hit without blowing your entire savings, it makes a lot of sense. It's fast, adjustable, solidly built and genuinely fun, provided you respect the power and accept the quirks (folding, weight, realistic range).

If you prioritise ultimate stability, long-term comfort and that "I'm not afraid of this road anymore" feeling, go MIA FOUR X2. If you prioritise outright performance per euro on good tarmac and want a more conventional, sporty ride, the RS JET will scratch that itch very nicely.

These metrics isolate the cold maths: how much you pay per unit of energy or speed, how efficiently the scooters turn battery into distance, how much weight you carry per unit of performance, and how fast they recharge. Lower values generally mean more efficiency or better value, while higher values in power-related metrics mean stronger performance for the same speed or faster charging. They don't capture comfort, safety or build quality-but they do reveal just how aggressively priced and power-dense the RS JET is, and how efficiently the MIA turns its battery into real-world kilometres.
