M4 Pro S

About

If you have been scouring the internet for an electric scooter that bridges the gap between a basic "last-mile" commuter and a rugged off-road beast without emptying your savings account, you have likely stumbled upon the IENYRID M4 Pro S. This machine, often labeled as the M4 Pro S+ or even the S+ Max depending on the specific configuration, is a fascinating entry in the mid-range market. It is designed for the rider who wants a bit of everything: the speed to keep up with city traffic, the suspension to handle gravel paths, and the luxury of a seat for those longer journeys where standing just feels like a chore. It positions itself as a "budget performance" scooter, offering specs that usually command a much higher price tag.

The philosophy behind the IENYRID M4 Pro S seems to be one of democratization. The designers clearly wanted to take the features found on high-end 1 500 € scooters-like dual suspension, off-road pneumatic tires, and comprehensive lighting-and pack them into a frame that costs closer to 431 €. It is a bold move that has made the brand a darling of the enthusiast community, particularly for those who enjoy a bit of DIY maintenance and "tinkering." This isn't just a toy; it is a serious piece of machinery built with a reinforced aluminum alloy frame, designed to support riders up to 150 kg, which is significantly higher than the standard 100 kg limit seen on most entry-level models.

What makes the M4 Pro S special is its versatility. It is one of the few scooters in this price bracket that successfully pulls off the "hybrid" identity. With its 10-inch all-terrain tires and a removable, gel-padded seat, it can transform from a standing street-shredder to a comfortable seated cruiser in seconds. Whether you are a student looking for a reliable way to get across a large campus, a commuter tired of the "first-mile" walk, or an adventurer wanting to explore local trails, the M4 Pro S is built to be your Swiss Army knife of personal electric transportation. It's a machine that invites you to go further and ride harder than a standard city scooter ever would.

Safety

When you are hitting speeds of 45 km/h, safety isn't just a feature-it's a necessity. The IENYRID M4 Pro S addresses this with a dual-braking system that combines mechanical disc brakes on both the front and rear wheels with an E-ABS (Electronic Anti-lock Braking System). In real-world terms, this means that when you squeeze those levers, you aren't just relying on friction; the motor itself helps to slow you down smoothly, preventing the wheels from locking up and sending you into a skid. Community feedback often highlights that the brakes are surprisingly quiet and efficient straight out of the box, though like any mechanical system, they do benefit from a bit of fine-tuning after the first few rides to ensure the pads are perfectly aligned.

Visibility is another area where the M4 Pro S punches way above its weight class. It features a "flawless" lighting system that makes it look like something out of a sci-fi movie at night. You get a high-brightness LED front headlight that actually throws a beam far enough to see potholes before you hit them, but the real showstoppers are the side ambient light stripes and multi-color running lights. These aren't just for aesthetics; they create a "halo" effect around the scooter, making you incredibly visible to cars from all angles. Add in the integrated turn signals and a bright rear brake light, and you have a package that significantly reduces the anxiety of night riding in busy urban environments.

Stability is the final piece of the safety puzzle. The 10-inch pneumatic tires provide a much larger contact patch with the ground than the 8-inch solid tires found on cheaper competitors. This extra grip is vital when navigating wet pavement or loose gravel. The wide, grippy deck also allows for a stable stance, which is crucial when you need to make quick maneuvers. While some users have noted that the stem can develop a bit of "wobble" over time if the bolts aren't kept tight, the overall build quality of the reinforced aluminum frame provides a sense of security that you just don't get from plastic-heavy commuter scooters. It feels solid, planted, and ready to protect the rider.

Performance

Let's talk about the heart of the beast: the 800W brushless motor. While many scooters in this price range settle for a 350W or 500W motor, the IENYRID M4 Pro S gives you a rated 800W with a peak output that can reach 1 000 W (and some community members even report peaks of 1 500 W on certain versions). What does this mean for you? It means 28Nm of torque that translates into "snap-your-neck" acceleration. When the light turns green, you aren't just moving; you are launching. This power is especially noticeable when tackling hills. While standard scooters often crawl to a halt on a 10-degree incline, the M4 Pro S is rated to conquer slopes of up to 25 degrees, making it a fantastic choice for those living in hilly cities.

The top speed of 45 km/h is where things get really exciting. On a flat stretch of road, this scooter feels incredibly fast. It's a level of speed that requires respect and, ideally, a full-face helmet. The scooter offers three distinct speed modes-Eco, City, and Off-Road-allowing you to tailor the performance to your environment. In Eco mode, the power delivery is gentle and battery-sipping, perfect for crowded sidewalks. Switch it into the "Off-Road" mode, and the full 800W is unleashed. Riders often report that the transition between gears is smooth, thanks to the upgraded controller, and the throttle response is intuitive rather than "jerky," which is a common complaint with high-torque budget scooters.

Real-world performance isn't just about top speed; it's about how that speed is maintained. The IENYRID M4 Pro S features a Kinetic Energy Recovery System (KERS), which is a fancy way of saying it regenerates a bit of battery life every time you coast or brake. This helps maintain a consistent power curve even as the battery starts to dip. Community members who weigh around 80-90 kg report that they can still hit 40 km/h even when the battery is at 50%, which is a testament to the efficiency of the 48V system. It's a performance profile that feels "grown-up"-it has the "gusto" to handle demanding commutes without feeling like it's struggling.

Finally, we have to mention the off-road capability. Those 10-inch pneumatic tires aren't just for show; they feature a self-cleaning tread pattern designed to shed mud and gravel. When you take this scooter off the pavement and onto a dirt path, the 800W motor provides the grunt needed to push through soft terrain. It doesn't bog down the moment it leaves the asphalt. While it's not a dedicated motocross machine, it handles "light" off-roading-like park trails, grass, and gravel driveways-with a level of competence that will leave you grinning from ear to ear. It's this "go-anywhere" performance that truly sets the M4 Pro S apart from the sea of generic city commuters.

Design

Aesthetically, the IENYRID M4 Pro S is a head-turner. It eschews the minimalist, "iPhone-on-wheels" look of many modern scooters in favor of a more industrial, rugged appearance. With its exposed suspension springs, beefy tires, and bold orange or gold accents, it looks like it means business. The frame is constructed from high-quality aluminum alloy, which strikes a balance between being lightweight enough to carry and durable enough to survive a tumble. Owners frequently mention that they get stopped by strangers asking what it is-it has a "cool factor" that is hard to ignore, especially when the colorful deck lights are pulsing.

The folding mechanism is one of the most critical parts of any portable scooter, and IENYRID has opted for a 3-step system that is designed for speed. You can collapse the stem and the handlebars in about 10 seconds, making it compact enough to fit into the trunk of an SUV or under a desk. One unique design touch is the adjustable handlebar height. This is a godsend for riders who are exceptionally tall or short, as it allows you to find the perfect ergonomic position whether you are standing or using the seat. The deck itself is also worth noting; at 21 inches long and 7.5 inches wide, it provides ample room to shift your weight, which is essential for maintaining balance at high speeds.

However, the design isn't just about looks; it's about functionality. The upgraded large central color LCD display is a massive improvement over previous generations. It's bright enough to read in direct sunlight and provides all the data you need at a glance: speed, battery level, gear, and even a trip odometer. The inclusion of a key-lock ignition is a brilliant design choice for security, acting as a basic anti-theft deterrent that many competitors lack. While the overall design is "busy," every component feels like it has a purpose, from the mudguards that actually keep you dry to the reinforced kickstand that can support the scooter's 24 kg weight without bending.

Comfort

Comfort is where the IENYRID M4 Pro S truly shines, largely thanks to its "Triple Shock" suspension system. This setup includes dual hydraulic shocks in the front and a robust spring system in the rear, complemented by an additional shock absorber built into the seat post itself. When you are riding over cobblestones, cracked pavement, or those annoying tactile paving slabs at crosswalks, the suspension works overtime to soak up the vibrations. Instead of feeling every jolt in your wrists and ankles, the ride feels "floaty" and controlled. Riders have noted that the 15 cm of travel in the suspension is enough to absorb significant potholes even at 40 km/h, which is a level of comfort usually reserved for much heavier, more expensive scooters.

Then there is the seat. For many, the inclusion of a removable, gel-padded seat is the primary reason to buy this scooter. It is height-adjustable and surprisingly ergonomic, making long-distance commutes far less fatiguing. If you have a 10 km ride to work, being able to sit down and cruise makes the journey feel more like a moped ride than a balancing act. The seat is also wide enough to be comfortable for larger riders, and the added spring damping underneath it means that even if the main suspension hits its limit, your spine won't take the hit. If you prefer the traditional standing experience, the seat can be removed in a couple of minutes, giving you a completely different riding dynamic.

The 10-inch pneumatic tires also play a massive role in the comfort equation. Unlike solid rubber tires, which can feel harsh and "chattery," air-filled tires provide a natural layer of cushioning. They deform slightly over small bumps, smoothing out the micro-vibrations of the road. This, combined with the wide deck and adjustable handlebars, allows for a relaxed riding posture. You don't feel "cramped" on the M4 Pro S. Whether you are leaning into a turn or just cruising down a long straightaway, the ergonomics are designed to keep you comfortable for the duration of the battery's range. It's the kind of scooter that encourages you to take the long way home just to enjoy the ride a little bit longer.

Range

Range is always a hot topic in the e-scooter world, and the IENYRID M4 Pro S offers a few different flavors depending on the battery you choose. The standard model comes with a 48V 12.5Ah battery (600 Wh), which the manufacturer claims can reach up to 30 km. However, as any seasoned rider knows, "manufacturer range" is often calculated using a 60 kg rider on a flat road in Eco mode. In the real world, if you are a 85 kg rider using the full power of the 800W motor and tackling a few hills, you can expect a realistic range of about 20-25 km. For many urban commuters, this is more than enough for a round trip, but it's something to keep in mind if you have a particularly long journey.

For those with "range anxiety," there is the "Max" version of the scooter, which packs a much larger 20Ah battery. This upgrade pushes the theoretical range up to 75 km, with real-world users reporting a solid 40-50 km of aggressive riding. This makes the M4 Pro S a legitimate long-distance machine. The battery uses high-quality lithium-ion cells designed for longevity, and the charging time is a manageable 6-8 hours. This means you can plug it in when you get to the office or when you go to bed, and it will be topped up and ready to go by the time you are. The charger itself is a standard 54.6V 2A unit, which is compact enough to carry in a backpack if you need a "top-up" during the day.

Factors like wind resistance, tire pressure, and temperature will always affect your mileage, but the community generally agrees that the M4 Pro S is honest about its capabilities. One of the best features for managing range is the "Cruise Control" function. If you maintain a constant speed for 8 seconds, the scooter takes over, allowing you to relax your thumb and helping the motor run at its most efficient RPM. This can extend your range by a noticeable margin on long, flat stretches. Overall, while the 12.5Ah version is perfect for city hops, the 20Ah version is the one to get if you plan on using this as your primary vehicle for weekend adventures.

Use and Practicality

In terms of daily usability, the IENYRID M4 Pro S is a bit of a "heavyweight" commuter. At 24 kg, it is significantly heavier than the ultra-portable scooters you might see in a shared fleet. This weight is the trade-off for the 800W motor, the massive battery, and the robust suspension. If you live on the fourth floor of a walk-up apartment with no elevator, you are going to get a workout. However, for most users, the weight is manageable thanks to the folding mechanism. It's easy to toss into the back of a car or roll onto a train, provided the station has ramps or elevators. It's a "sturdy" kind of heavy that gives you confidence on the road, even if it's a bit of a chore to carry up stairs.

The practicality of the M4 Pro S is enhanced by its "all-weather" aspirations. With an IP54 waterproof rating, it can handle splashes and light rain without the electronics frying. While you shouldn't go submerged-puddle-jumping, it means you don't have to panic if you get caught in a sudden drizzle on your way home. The inclusion of a loud electronic horn and a comprehensive toolkit in the box also adds to the practical value. You have everything you need to perform basic maintenance-like tightening the folding latch or adjusting the brake calipers-right from day one. This "ready-to-ride" approach is something the community deeply appreciates.

One minor practical limitation mentioned by users is the complexity of the "P-settings" on the LCD. While it allows for incredible customization (like adjusting the strength of the regenerative braking or setting a speed limit), the instruction manual can be a bit sparse. Thankfully, the IENYRID community is very active on platforms like Reddit and YouTube, where you can find "cheat sheets" for every setting. Once you have it dialed in to your preference, the scooter becomes a seamless part of your routine. It's a machine that rewards a little bit of initial effort with a lot of long-term utility, making it a practical choice for anyone who wants a "real" vehicle rather than a toy.

General Assessment

The general consensus on the IENYRID M4 Pro S is that it is a "diamond in the rough." It is widely regarded as one of the best value-for-money propositions on the market today. Owners love the fact that they can get "pro-level" performance for an entry-level price. The sentiment among the community is overwhelmingly positive, with many riders expressing surprise at how well the scooter handles daily abuse. It has earned a reputation as a "tank"-a bit unrefined in some areas, perhaps a little noisy in the suspension, but fundamentally tough and reliable where it counts. It's a scooter that feels like it was built by people who actually ride, rather than just a marketing team.

However, it is important to be realistic: this is a budget performance scooter, and that comes with certain expectations. The community consensus is that you should treat the M4 Pro S as a "kit" that needs a little love. Most experienced owners recommend going over the entire scooter with a set of hex keys when it arrives to ensure every bolt is tight. There are occasional reports of "rattling" mudguards or a "squeaky" front suspension, but these are usually easily fixed with a bit of lubricant or a rubber washer. For those who are willing to do a tiny bit of "preventative maintenance," the M4 Pro S rewards them with a riding experience that rivals scooters costing twice as much.

Ultimately, the IENYRID M4 Pro S lives up to the hype. It delivers on its promise of speed, comfort, and versatility. It isn't as polished as a high-end Segway, but it is far more exciting to ride. It has "soul." The combination of the punchy 800W motor and the plush suspension creates a sense of freedom that is hard to find elsewhere at this price point. Whether you are using it for a 20 km commute or just for "street play" on the weekends, the M4 Pro S consistently punches above its weight, making it a standout choice in a very crowded market.

Who Is This Scooter For?

The IENYRID M4 Pro S is the perfect match for the "value-conscious enthusiast." If you are the kind of person who researches every spec, watches ten different YouTube reviews, and isn't afraid to get your hands a little dirty to save a few hundred Euros, you will love this machine. It's ideal for the commuter who has a longer-than-average journey and needs the comfort of a seat and a suspension system that won't leave them with "vibration white finger" by the time they get to work. It's also a great choice for heavier riders who find that standard 250W scooters simply don't have the torque to get them up hills.

On the flip side, this might not be the best choice for someone who wants a "zero-maintenance" appliance. If you want something that you can just pull out of the box and never think about again, you might find the occasional need to tighten a bolt or adjust a brake cable frustrating. It's also not the best choice for someone who needs to carry their scooter up multiple flights of stairs every day-at 24 kg, it's a beast. This is a scooter for someone who views their commute as an adventure, someone who wants the power to "zip" through traffic and the capability to take a shortcut through the park without worrying about a flat tire.

Experience level is another factor. While IENYRID markets this as "beginner-friendly" due to its intuitive controls and stable ride, the 45 km/h top speed is no joke. We would recommend it for beginners who are responsible and willing to wear proper safety gear, but it's also a fantastic "step-up" scooter for someone who has outgrown their first 25 km/h city commuter. It's a machine that grows with you-as you gain confidence, you can unlock more of its performance. In short, if you want the most "bang for your buck" and you appreciate a rugged, versatile design, the M4 Pro S is calling your name.

The most praised aspect of the IENYRID M4 Pro S is undoubtedly its "bang-for-the-buck" factor. Community members frequently point out that to get similar power and suspension from a "big name" brand, you would easily be spending over 800 €. The combination of the 800W motor and the 10-inch tires creates a "go-anywhere" feeling that users find addictive. Many owners also rave about the lighting system, noting that it doesn't just look cool-it actually makes them feel much safer when riding home after dark.

Community Feedback - Cons

• Weight: At 24 kg, it is heavy and difficult to carry up stairs.
• Maintenance Required: Bolts often need tightening out of the box and periodically thereafter.
• Noisy Suspension: Some users report "clunking" or "squeaking" sounds from the front shocks.
• Vague Manual: The instructions for the P-settings and assembly can be difficult to follow.
• Stem Wobble: If not properly maintained, the folding mechanism can develop some play.
• Customer Support: Some users have reported slow response times from the manufacturer.
• Rattling Parts: Mudguards and other plastic components can rattle on rough terrain.
• Charging Port Cover: The rubber flap for the charging port can be flimsy and hard to close.
• Tire Flats: Like all pneumatic tires, they are susceptible to punctures if not kept at the right pressure.
• Bulky Folded Size: Even when folded, it takes up a significant amount of space.
• Brake Adjustment: The mechanical discs often require a bit of "bedding in" and alignment.
• Error Codes: Some users have experienced confusing error codes (like E-006) related to the controller.

The most common complaints center around "refinement" issues rather than fundamental failures. The "rattling" and "squeaking" are the most frequent gripes, but as the community often points out, these are usually "five-minute fixes" with a wrench or some WD-40. The weight is a legitimate concern for apartment dwellers, and the "stem wobble" is something that requires regular attention to ensure safety. While these cons are worth noting, most owners feel they are a fair trade-off for the performance and price, provided you are willing to be a proactive owner.

Value for Money

When you look at the average market price of 431 €, the value proposition of the IENYRID M4 Pro S is staggering. To put this in perspective, many "name brand" scooters at this price point offer a 250W motor, no suspension, and a top speed of only 25 km/h. With the M4 Pro S, you are essentially getting a "prosumer" level scooter for an entry-level price. You are paying for the raw materials and the performance specs, rather than a massive marketing budget or a premium brand logo. For the budget-conscious rider, it is arguably one of the smartest investments you can make in the e-scooter world.

Is it a bargain? Absolutely. Even if you factor in the cost of a few upgrades-like adding some tire sealant (Sliming) to prevent flats or buying a better set of hex keys for maintenance-you are still hundreds of Euros ahead of the competition. The inclusion of the seat, the toolkit, and the comprehensive lighting system adds even more "out-of-the-box" value. While it might lack the "polish" of a 1 200 € scooter, it delivers 90% of the experience for less than half the price. It's the kind of deal that makes you wonder why anyone would pay more for a less capable machine.

Known Alternatives

If the IENYRID M4 Pro S doesn't quite hit the mark for you, there are a few other contenders in this price and performance bracket that are worth a look. One popular alternative is the VOLTAIK ION 400. This scooter tends to focus more on a sleek, urban design and might appeal to those who find the M4 Pro S a bit too "rugged" or industrial. It offers a more streamlined folding process but generally lacks the raw off-road power and the triple suspension system of the IENYRID.

Another strong competitor is the TURBOANT X7 Max, which is famous for its removable battery feature. If you need to charge your battery away from the scooter (for example, in an office or a small apartment), the TurboAnt is a fantastic choice. However, it typically features smaller tires and a less powerful motor than the M4 Pro S. For those who prioritize a "brand name" experience, the SEGWAY F3 Pro or the HIBOY S2 Pro are common choices. The Segway offers superior app integration and a more "polished" feel, while the Hiboy is known for its solid tires which eliminate the risk of flats-though at the cost of a much harsher ride compared to the IENYRID's plush pneumatic setup.

Finally, the JOYOR G5 is often mentioned in the same breath as the M4 Pro S. It offers a similar "performance-on-a-budget" vibe with a powerful motor and good suspension. The choice between them often comes down to local availability and specific aesthetic preferences. Each of these alternatives has its own strengths, but the IENYRID M4 Pro S remains the "king of features" for those who want the most comprehensive hardware package for their money. You can check out the IENYRID and compare it to others at /en/pevpedia/escooters/2swift-board to see which one fits your lifestyle best.
