FOUR X4 (mobility version 4x4)

About

If you have ever looked at a standard two-wheeled electric scooter and thought, "This is fun, but what if I wanted to cross a sandy beach, climb a rocky mountain path, or simply not worry about balancing at a stoplight?" then the MIA FOUR X4 is the machine that answers your very specific, adrenaline-fueled prayers. This is not your average commuter vehicle; it is a genre-bending hybrid that sits somewhere between a high-performance electric scooter and a stand-up ATV. Designed by MIA Dynamics, a company that seems intent on rewriting the rules of personal mobility, the MIA FOUR X4 (mobility version 4x4) is the flagship of their fleet, boasting a level of engineering that is frankly overkill for the sidewalk-and that is exactly why we love it.

The philosophy behind the MIA FOUR X4 is fascinating. On paper, and indeed in some of its certifications (UL2272), it is classified as a "mobility scooter." This might conjure images of slow-moving plastic carts in grocery stores, but the reality is a carbon-fiber and aerospace-aluminum beast capable of tearing up gravel trails. It features a patented tilting mechanism that allows the four wheels to articulate independently. This means you get the static stability of a quad-you won't tip over when you stop-combined with the dynamic leaning capability of a motorcycle or ski. It is designed for the adventurer who wants the agility of a two-wheeler but the traction and planted feel of a 4x4 vehicle.

Positioned as the ultimate all-terrain solution, the MIA FOUR X4 is marketed towards a diverse crowd: from extreme sports enthusiasts and hunters to security patrols and land surveyors. It is a machine built to conquer environments where a standard Dualtron or Segway would simply sink or slide out. With four independent hub motors providing all-wheel drive, this scooter isn't just pushing you forward; it's clawing its way over obstacles. It represents a shift in the market towards "hyper-scooters" that prioritize capability and ruggedness over portability, offering a ride that feels more like piloting a futuristic land-speeder than riding a kick scooter.

Safety

When you are dealing with a machine that weighs nearly 60 kg and has the torque to climb a 30-degree incline, safety is not just a feature; it is a necessity. The most significant safety feature of the MIA FOUR X4 is inherent in its design: the four-wheel platform. Unlike a two-wheeled scooter where a patch of loose gravel or a wet manhole cover can send you sliding across the pavement, the X4 offers four contact points with the ground. This redundancy in traction is a game-changer. If one wheel slips, you have three others driving you forward and keeping you upright. The patented tilting mechanism also contributes to safety by keeping all four wheels planted on the ground even when you are carving hard into a turn, providing a level of cornering confidence that is hard to match.

Stopping power is provided by a specialized hydraulic braking system. We are talking about dual hydraulic disc brakes on both the front and rear axles, utilizing substantial 140 mm discs. In the world of electric mobility, hydraulic brakes are the gold standard because they offer modulation. You don't just get "on" or "off" braking; you get a granular feel that allows you to scrub speed gently before a corner or lock them up for an emergency stop. Given the momentum this heavy machine can build, having hydraulic stopping power is critical. The brakes also feature a parking lock mechanism, which is essential for a rolling vehicle that you might want to park on a slope.

Visibility is another area where the MIA FOUR X4 shines-literally. It comes equipped with a comprehensive lighting suite, including dual LED headlights that are integrated into the frame, along with tail lights and brake lights. This isn't just about seeing the trail ahead; it's about being seen. The low, wide stance of the scooter already gives it a significant road presence, but the lighting ensures that you are visible to cars or other riders in low-light conditions. Furthermore, the unit is UL2272 certified, which is a rigorous electrical safety standard for personal e-mobility devices, giving riders peace of mind regarding the battery and electrical systems.

Performance

Let's talk about power, because the MIA FOUR X4 has it in spades. The heart of this beast is a quad-motor setup-yes, a motor in every wheel-delivering a peak output of 7 200 Watts. To put that in perspective, a standard rental scooter usually has about 350 Watts. The acceleration on the X4 is described by users as "ready to rip." With the ability to switch between 4x2 and 4x4 modes, you can tailor the power delivery to your needs. In full 4x4 mode, the torque is instantaneous. It doesn't just accelerate; it launches. This is particularly noticeable on loose terrain like sand or mud, where the all-wheel-drive system ensures that power is translated into forward motion rather than just spinning wheels.

Top speed is a bit of a "choose your own adventure" situation. Out of the box, to comply with mobility scooter regulations in many regions, it may be limited to 12 km/h or 25 km/h. However, the hardware is capable of much more. For off-road use on private land, and with the limiter unlocked (where legal), this machine can hit speeds upwards of 72 km/h (45+ mph). Riding a standing platform at 70 km/h is an exhilarating experience that borders on terrifying for the uninitiated, but the wide stance and suspension make it feel surprisingly stable at speed compared to a two-wheeler.

Hill climbing is where the MIA FOUR X4 truly leaves the competition in the dust. Most electric scooters struggle with inclines over 15 or 20 degrees. The X4, with its massive torque and four driven wheels, is rated for 30-degree climbs. Community feedback supports this, with riders noting that it eats up steep driveways and dirt trails without breaking a sweat. The feeling of being pulled up a hill by the front wheels while being pushed by the rear wheels is unique and provides a sense of unstoppable momentum. Whether you are navigating a steep urban street or a mountain fire road, the X4 feels like a tractor in the best possible way.

Design

The aesthetic of the MIA FOUR X4 is best described as "industrial skeletal chic." It doesn't try to hide its mechanics behind smooth plastic fairings. Instead, it proudly displays its double-wishbone suspension arms, exposed shocks, and rugged aerospace-grade aluminum frame. It looks like something that rolled out of a sci-fi movie set or a military drop-ship. The wide track width (nearly 69 cm) gives it an aggressive, planted stance that immediately communicates its off-road intentions. It is available in a sleek finish that emphasizes its mechanical nature, and the minimal deck design keeps the focus on the massive 15-inch tires.

One of the most surprising design elements is that, despite its size and complexity, it is foldable. The steering column collapses down, reducing the height to just 450 mm. This is a brilliant bit of engineering that allows this quad-scooter to fit into the back of a large SUV or station wagon. The folding mechanism is robust, designed to handle the leverage of the handlebars during rough riding without developing the dreaded "stem wobble" common in lesser scooters. The handlebars themselves are ergonomic, featuring intuitive controls for the drive modes and a clear digital display that keeps you informed of your vitals.

The "mobility" aspect of the design is interesting. While it looks aggressive, it includes features like a mounting point for a seat (optional), mirrors, and reflectors that align with mobility device requirements. This dual-nature design allows it to be a wolf in sheep's clothing-a high-performance ATV that can legally be used in spaces where a gas-powered quad would be banned. The build quality is widely praised by the community, with the aluminum structure feeling solid and durable, capable of taking a beating on the trail without rattling apart.

Comfort

If you have ever ridden a solid-tire scooter on cobblestones, you know that suspension matters. The MIA FOUR X4 takes comfort to an entirely different level with its fully independent, double-wishbone suspension system. This is the same type of suspension geometry found on high-performance sports cars and full-sized ATVs. Each wheel can move up and down independently, soaking up bumps, roots, and potholes without transferring the shock to the rider. The vertical shock absorbers are tuned to handle the weight of the vehicle plus a rider (and gear) up to 150 kg, providing a plush ride that "floats" over gravel.

The ride quality is further enhanced by the massive 15-inch pneumatic tires. These large-diameter wheels roll over obstacles that would stop a 10-inch scooter wheel dead in its tracks. The combination of the air-filled tires and the sophisticated suspension means that vibration fatigue-the tiring shaking sensation you get on long rides-is significantly reduced. You can ride the X4 for hours across mixed terrain without feeling like you've been in a boxing match.

The standing position is natural and commanding. Because the deck is wide and the vehicle is self-balancing at a stop (mostly), you don't have to constantly shift your weight to stay upright. However, the unique tilting deck allows you to lean into turns, engaging your core and legs in a way that feels sporty and active. It's a comfortable ride, but it's also an engaging one. For those who prefer to sit, the optional seat attachment turns the X4 into a very capable long-distance cruiser, making it accessible for riders who might not have the stamina to stand for a 60 km adventure.

Range

Range anxiety is the enemy of electric vehicle adoption, but the MIA FOUR X4 fights back with a substantial energy reservoir. It is equipped with a 60V 35Ah battery pack, utilizing high-quality Samsung 21700 cells. In the world of batteries, Samsung cells are renowned for their reliability, safety, and longevity. The manufacturer claims a maximum range of up to 120 km in 4x2 mode under optimum conditions. However, as any experienced EV enthusiast knows, "optimum conditions" usually means a lightweight rider on a flat road with a tailwind.

In real-world usage, especially when utilizing the power-hungry 4x4 mode and tackling hills or off-road terrain, the range will naturally be lower. Community feedback and realistic estimates suggest a solid 60 to 90 km of mixed riding is achievable. This is still an impressive figure that allows for substantial day trips. If you are pushing the machine to its limits-full speed, deep sand, steep climbs-expect the range to drop closer to the 50-60 km mark. However, for a vehicle of this weight and power, that is still excellent performance.

A critical feature for range extension is the removable battery. Unlike many scooters where the battery is buried in the deck, the X4's battery can be swapped out. This means if you invest in a second battery, you can effectively double your range or keep one charging while you ride. Charging time is around 8 hours with the standard charger, which is an overnight affair. The ability to remove the battery also makes charging more convenient; you can leave the muddy scooter in the garage and take just the battery inside to charge.

Use and Practicality

Let's be honest about the practicality: the MIA FOUR X4 is a heavy piece of machinery. Weighing in at around 57 kg (without the battery) and roughly 67.5 kg with it, this is not a scooter you are going to carry up a flight of stairs to a third-floor apartment. It is not a "last-mile" solution for taking on the bus or train. This is a vehicle that requires ground-level storage, a garage, or a very secure locking situation. Its width also means you won't be weaving through tight pedestrian traffic on a busy sidewalk with the same ease as a skinny Xiaomi scooter.

However, for its intended purpose, it is incredibly practical. If you live in a rural area, have a large property, or enjoy weekend adventures, the X4 is unmatched. It can serve as a silent utility vehicle for checking fence lines, a fun runabout for camping trips, or a serious commuter for those whose route involves unpaved roads. The payload capacity of 150 kg means you can carry a heavy backpack, or even tow a small trailer (with the optional hitch accessory), making it a viable workhorse for certain tasks.

The folding mechanism adds a layer of practicality that full-sized ATVs lack. While you can't carry it, you can transport it. It fits into the back of a van or a large SUV, meaning you don't need a dedicated trailer to take it to the trails. The Rider App is another practical touch, offering navigation, ride data tracking, and theft protection features. For the right user, the X4 bridges the gap between a toy and a tool, offering utility that justifies its footprint.

General Assessment

The general consensus in the electric mobility community is that the MIA FOUR X4 is a marvel of engineering that occupies a unique and exciting niche. It is widely regarded as a "beast" and a "tank," with owners praising its build quality and sheer capability. It is not seen as a competitor to standard commuting scooters, but rather as a new category of personal electric vehicle. The "cool factor" is undeniable; it turns heads wherever it goes, and the riding experience is often described as surfing on land.

However, it is not without its critiques. Some early adopters have noted that the throttle response can be aggressive, particularly at low speeds, making it feel a bit jerky until you get used to the power curve. It requires a different riding style than a two-wheeler, and there is a learning curve to mastering the tilt mechanism. The price point also places it firmly in the luxury or enthusiast category. It is an investment, not an impulse buy.

Overall, the sentiment is overwhelmingly positive for those who understand what they are buying. It delivers on its promise of all-terrain freedom. It is robust, powerful, and incredibly fun. If you can live with the weight and the price, it offers a riding experience that simply doesn't exist elsewhere in the market. It is a serious machine for serious fun, and it has successfully carved out a loyal following among those who demand more than just pavement pounding from their electric vehicles.

Who Is This Scooter For?

The MIA FOUR X4 is for the rider who refuses to be limited by terrain. It is perfect for the outdoor enthusiast who wants to explore forest trails, beaches, and mountain paths silently, without the noise and fumes of a gas ATV. It is ideal for hunters who need a stealthy way to access remote areas, or for fishermen who need to cross dunes to get to the perfect spot. It is also a fantastic option for land owners and farmers who need a nimble, quick way to get around their property without firing up a truck.

Interestingly, it is also for a specific segment of urban riders: those who prioritize safety and stability above all else. If you are an older rider or someone who doesn't feel confident balancing a two-wheeled scooter at 40 km/h, the four-wheel stability of the X4 offers a confidence-inspiring alternative. It allows you to keep up with traffic and handle potholes with a safety margin that two wheels can't provide.

Conversely, this scooter is not for the casual city commuter who needs to hop on and off public transit or store their ride under an office desk. It is not for the budget-conscious buyer looking for a cheap way to get to work. It requires space, strength to manage its weight, and a budget to match its capabilities. If you live in a walk-up apartment in a crowded city center, this is likely not the droid you are looking for.

The sense of freedom-that there is no "wrong road"-is the primary driver of satisfaction among owners. The suspension and stability turn terrifying terrain into a playground.

Community Feedback - Cons

• Heavy Weight: At nearly 60 kg, it is difficult to lift, making it impossible to carry up stairs or lift into a high truck bed alone.
• Jerky Throttle: Some users report the throttle can be overly sensitive at low speeds, requiring a delicate touch to avoid lurching.
• Large Footprint: It takes up a lot of space in a garage or hallway; it's not a "tuck away in the corner" device.
• Price: The high cost is a barrier for many, making it a luxury item rather than a mass-market solution.
• Charging Time: The 8-hour charge time is considered long by some, especially for a battery of this size.
• Learning Curve: The tilting steering feels different from a bike or standard scooter, requiring some practice to master.
• Limited Top Speed (Stock): Some enthusiasts are frustrated by the factory speed limiters and the need to unlock the full potential.
• Brake Maintenance: With four wheels and high weight, the brake pads can wear faster if riding aggressively in gritty conditions.
• Availability of Parts: Depending on the region, getting specific replacement parts can sometimes take longer than mainstream brands.

The most common complaint revolves around the throttle mapping. For a machine with this much torque, riders want a smooth, linear delivery, and the "on/off" feeling at low speeds can be intimidating for beginners. While the weight is a known trade-off for the performance, it remains a logistical challenge for many users who didn't anticipate just how heavy 57 kg feels in the real world.

Value for Money

With a price tag hovering around 7 394 €, the MIA FOUR X4 is undeniably a premium product. It sits in a price bracket where you could buy a decent used car or a very high-end electric motorcycle. So, is it worth it? If you view it strictly as a "scooter," the price seems astronomical. However, if you view it as a compact, electric, stand-up ATV, the value proposition shifts. You are paying for a patented suspension system, four motors, and a unique chassis that simply doesn't exist elsewhere.

Compared to high-end racing scooters like the Rion or Weped, the price is actually somewhat competitive. Those machines offer speed, but they don't offer the 4x4 off-road capability or the stability of the X4. You are paying for the R&D that went into the tilting mechanism and the complex drivetrain. For a professional who needs this for land management or security, the price is justifiable as a business expense. For the recreational rider, it is a luxury toy, but one that offers a unique experience that cheaper alternatives cannot replicate.

Ultimately, the value is in the capability. There is no other machine that fits in the trunk of a car, requires no gas, and can climb a 30-degree sand dune. If you need that specific combination of features, the MIA FOUR X4 is not just good value; it's the only game in town. If you just want to commute on asphalt, you are overpaying for capability you will never use.

About the Brand

MIA Dynamics is a forward-thinking company that has positioned itself at the intersection of micro-mobility and extreme sports. They are not just slapping parts together; they are innovators with a strong focus on mechanical patents, particularly regarding their suspension and steering geometries. The company emphasizes a collaboration between European design standards and Asian manufacturing technology, aiming to produce vehicles that are both high-tech and robust.

The brand has built a reputation for pushing boundaries. They identified a gap in the market between the two-wheeled scooter and the four-wheeled ATV and decided to fill it. Their marketing often highlights the "mobility" aspect to ensure their vehicles can be certified for use in various jurisdictions (like the UL2272 certification), but their engineering soul is clearly in the off-road world. They are known for being responsive to their niche community, though like many boutique high-end manufacturers, their global support network is still growing compared to giants like Segway-Ninebot.

MIA Dynamics seems committed to the idea that electric mobility shouldn't be boring or limited to paved bike lanes. Their "Four X" series is a testament to this vision. If you are intrigued by their engineering but perhaps want something slightly lighter or less aggressive, it is worth checking out their other models, though the X4 remains the crown jewel of their lineup.

Known Alternatives

If the MIA FOUR X4 has piqued your interest but you are not quite ready to pull the trigger, there are a few other high-performance machines in the "hyper-scooter" category worth considering. While few offer the exact 4-wheel tilting configuration of the MIA, these alternatives offer similar thrills, price points, or capabilities.

For those who love the industrial, heavy-metal aesthetic and want extreme performance on two wheels, the WEPED DARKKNIGHT CYBERFOLD is a strong contender. It is a masterpiece of Korean engineering with a unique folding mechanism and incredible speed, though it lacks the off-road stability of the 4x4 system. If speed is your absolute priority and you stick mostly to tarmac, the RION MOTORS RE90 or the RION MOTORS Apex are the hyper-cars of the scooter world. They are lighter, faster, and made of carbon fiber, but they are race machines, not off-road tractors like the MIA.

If you like the idea of the MIA but want something slightly less intimidating or lower cost, you might look at its little brother, the MIA FOUR X2 (mobility version 4x2). It shares much of the DNA but with two motors instead of four. Finally, for a completely different take on big-wheel scootering, the HUGO BIKE BIG One X offers a bicycle-like feel with a large front wheel, providing great stability and comfort on trails, though without the 4-wheel drive capability.
