4Flex

About

If you have ever tried to wrestle a standard electric scooter into the trunk of a compact car or navigate a crowded rush-hour train with a 15 kg aluminum beast, you know the struggle is real. Enter the WEGOBOARD 4Flex, a machine that seems to defy the laws of physics-or at least the conventions of personal mobility. As a technology journalist who has ridden everything from dual-motor monsters to flimsy toys, I can tell you that the 4Flex is something entirely different. It is not just a scooter; it is a piece of urban origami. Developed in partnership with HX, this scooter is designed with a singular, obsessive focus: portability. It is marketed as the most compact electric scooter on the market, and quite frankly, that claim holds water. The "4Flex" name isn't just marketing jargon; it refers to the ingenious four-point folding system that collapses the handlebars, the stem, and the frame into a package so small (62 cm x 12 cm x 25,9 cm) that it can genuinely fit inside a standard gym bag or a large backpack.

The philosophy behind the WEGOBOARD 4Flex is clear: it aims to be the ultimate "last-mile" solution. Many scooters claim this title but are still too heavy or awkward to carry for more than a minute. The 4Flex, weighing in at a featherlight 9,5 kg, is designed for the multi-modal commuter-the person who takes a train from the suburbs, unfolds their ride at the station, zips to the office, and then tucks the scooter under their desk like an umbrella. It positions itself as a "connected ecological jewel," moving away from the rugged, sporty image of many competitors and leaning hard into practicality and lifestyle integration. It's not trying to be a racing machine; it's trying to be an invisible companion that is there when you need it and disappears when you don't.

What makes this scooter particularly interesting to an enthusiast is how it manages to cram essential features into such a small footprint. Usually, when you go this small, you sacrifice everything-suspension, battery life, and build quality. However, WEGOBOARD has managed to include a removable battery system (housed in the stem), front suspension, and a proper LCD display. It is a bold attempt to balance the extreme portability of a kick scooter with the comfort and power of an electric vehicle. For the urban dweller living in a fifth-floor walk-up apartment without an elevator, or the professional who doesn't want to leave an expensive vehicle locked outside, the 4Flex presents a compelling, almost unique, value proposition in a crowded market.

Safety

When we talk about safety on a scooter this small, the conversation has to start with the wheels. The WEGOBOARD 4Flex rides on 5-inch (or 5,5-inch depending on the specific batch) reinforced solid rubber tires. I have to be honest with you: small, solid wheels require a different riding style. Unlike large pneumatic tires that roll over potholes, these require you to be hyper-aware of the road surface. However, WEGOBOARD has mitigated the inherent harshness and instability of small wheels by including front shock absorbers. This suspension is crucial not just for comfort, but for safety-it helps keep the tire in contact with the ground over bumps, providing better traction than a rigid frame would. Stability at the top speed of 25 km/h is surprisingly decent, though I always advise riders to keep two hands firmly on the bars, as smaller wheels can be twitchy if you hit a rut unexpectedly.

The braking system on the 4Flex is a hybrid setup designed to save weight while ensuring stopping power. Up front, you have an electromagnetic brake equipped with KERS (Kinetic Energy Recovery System). This means when you let off the throttle or engage the brake, the motor reverses resistance to slow you down while trickling a bit of power back into the battery. It's smooth and doesn't lock up the wheel, which is vital for preventing over-the-bar accidents. For emergency stops, the rear fender acts as a mechanical foot brake. While this might feel "old school" to those used to disc brakes, it is highly effective and reliable on a scooter of this weight. The combination allows for controlled deceleration in traffic and immediate stopping power when you really need it.

Visibility is another key safety factor, especially for a commuter vehicle that will likely see use during winter evenings. The 4Flex is equipped with a powerful front LED light that does a respectable job of illuminating the path ahead, rather than just making you visible to others. The newer versions of this model have been updated to meet stricter regulations, now featuring rear LEDs as well. This is a massive improvement, ensuring that cars coming up behind you can see you clearly. The inclusion of an audible warning device (horn) rounds out the safety package, giving you a way to alert pedestrians in busy city centers. While it may not have the imposing presence of a large cruiser, the lighting and braking systems are well-thought-out for its intended urban environment.

Performance

Let's talk about what happens when you press the throttle. The WEGOBOARD 4Flex is powered by a 250 W brushless motor, which can peak at 500 W of instantaneous power. Now, 250 W is the standard for street-legal scooters in many European regions, but on a scooter that only weighs 9,5 kg, that power goes a lot further than it does on a 20 kg machine. The power-to-weight ratio is actually quite snappy. Acceleration is smooth rather than aggressive, which is exactly what you want on a device with a short wheelbase. It picks up speed linearly, and in the highest speed mode, it will happily cruise at 25 km/h on flat ground. For zipping through bike lanes and navigating city traffic, it feels nimble and responsive.

However, performance is always relative to the terrain. The manufacturer claims it can handle slopes up to 15 degrees. In the real world, this depends heavily on the rider's weight. If you are a lightweight rider (around 60-70 kg), you will find it handles moderate city inclines without much fuss, perhaps slowing down a bit but keeping momentum. If you are pushing the 100 kg weight limit, you should expect the scooter to struggle on steeper hills, likely requiring a few kicks to help it along. This is simple physics; a compact motor has its limits. But for the vast majority of urban topography-bridges, underpasses, and gentle rises-the 4Flex performs admirably.

The riding experience is defined by the three speed modes available via the LCD screen. Mode 1 is perfect for navigating crowded sidewalks (where permitted) at a walking pace. Mode 2 offers a cruising speed of around 15 km/h, which is the sweet spot for maximizing range and navigating tricky surfaces. Mode 3 unlocks the full 25 km/h potential. What I appreciate is that the controller seems well-tuned; there is no jerky "on-off" feeling that plagues some cheaper scooters. The throttle response is predictable, which allows you to ride with confidence even when maneuvering in tight spaces between pedestrians or cars.

Design

The design of the WEGOBOARD 4Flex is, without exaggeration, a feat of engineering. Most scooters fold in half; the 4Flex essentially folds into itself. The "4-fold" mechanism involves collapsing the handlebars down, retracting the stem height, and then folding the stem against the deck. The result is a package that looks more like a piece of professional camera equipment or a folded tripod than a vehicle. The structure is built from aluminum, which provides the necessary rigidity while keeping the weight low. The finish is typically a sleek black, giving it a professional, understated look that fits right in at a corporate office. It doesn't look like a toy; it looks like a tool.

One of the most clever design elements is the battery placement. Instead of being under the deck (which would make the deck thicker and the scooter heavier to lift), the cylindrical battery slides into the stem. This "tube" battery is removable, which is a massive design win. You can leave the scooter locked in a bike room or the trunk of your car and just take the lightweight battery tube inside to charge. The deck itself is slim, streamlined to match the compact ethos. While it doesn't offer the sprawling foot room of a touring scooter, the grip tape is high quality, and the geometry works well for the "one foot behind the other" stance.

However, complex designs do introduce more points of potential wear. The folding mechanisms-the latches and hinges-are the critical components here. Owners need to treat them with respect; you can't just slam this scooter open and closed like a brute. It requires a specific sequence. The aesthetic is very "tech-forward," with the LCD screen integrated neatly into the handlebar assembly, displaying speed, battery life, and mode clearly. It's a machine that draws looks, not because it's flashy, but because when people see you fold it up in ten seconds and walk into a café, they are genuinely confused about where your vehicle went.

Comfort

Comfort on an ultra-portable scooter is usually the first thing to be sacrificed, so I approached the 4Flex with skepticism. Riding on 5-inch or 5,5-inch solid tires usually feels like riding a jackhammer. However, WEGOBOARD has done a commendable job of mitigating this with the front suspension system. The shock absorbers are surprisingly active. They won't turn a cobblestone street into a cloud, but they effectively filter out the high-frequency vibrations from asphalt grain and small cracks in the pavement. This prevents that "numb hands" feeling that often occurs after riding solid-tire scooters for more than ten minutes.

The standing position is compact. The handlebars are narrower than on full-sized scooters, which aids in portability but means your chest is less open while riding. For a tall rider, the stem height is adjustable, which is a fantastic feature often missing on even expensive scooters. You can dial in the height to match your stature, preventing you from having to hunch over. The deck is narrow, so you won't be dancing around, but it's sufficient for a stable stance. The solid tires mean you never have to worry about punctures-a huge psychological comfort-but they do transmit hard impacts (like dropping off a curb) directly to the frame, so you learn to ride "light," using your knees as additional suspension.

Is it comfortable for a 20 km joyride? Probably not. But that's not what it's for. For a 3 to 5 km commute, it is perfectly adequate. The suspension takes the edge off, and the lightweight nature of the scooter actually adds to the comfort in a different way: the comfort of not straining your back when you have to pick it up. Physical comfort isn't just about the ride; it's about the entire user experience, and the ease of manipulation makes living with the 4Flex very comfortable indeed.

Range

The WEGOBOARD 4Flex is equipped with a 36V 5 Ah Lithium-ion battery (some older or specific specs mention a 24V variant, but the 36V is the standard for current performance). The manufacturer claims a range of up to 20 km. In the world of electric mobility, we know that "up to" does a lot of heavy lifting. In real-world testing conditions-meaning a rider of average weight (75 kg), riding in mixed conditions with some stop-and-go traffic and using the faster speed modes-you are more likely to see a range of 12 to 15 km. If you are lighter and stick to Eco mode on flat ground, you might approach that 20 km figure.

However, the 4Flex has an ace up its sleeve: the interchangeable battery. Because the battery is a lightweight cylinder that pops out of the stem in seconds, you can easily carry a spare in your backpack. This effectively doubles your range to a realistic 25-30 km without adding significant weight to the scooter itself. This modularity is a game-changer. It means you are never truly tethered to a charging point. If you run out of juice, you swap the battery like reloading a oversized flashlight and keep going.

Charging time is another highlight. Because the battery capacity is relatively small (5 Ah), it charges very quickly. You are looking at a full charge in about 2 to 3 hours. This means you can easily top it up at the office before lunch is even over. The convenience of the removable battery cannot be overstated; you don't need to drag a dirty scooter into your living room or office. You just bring the battery in and plug it into a standard outlet. This feature alone makes the range anxiety much less of an issue compared to scooters with fixed batteries.

Use and Practicality

This is the section where the WEGOBOARD 4Flex absolutely shines. If you judge a scooter by how easy it is to live with, the 4Flex is a world champion. Weighing just 9,5 kg, it is one of the lightest electric scooters in existence. To put that in perspective, most "lightweight" competitors weigh around 12-14 kg, and rental scooters can weigh over 20 kg. You can carry the 4Flex up three flights of stairs without breaking a sweat. You can hold it with one hand while opening a door. For petite riders or those with back issues, this weight difference is transformative.

The folding mechanism makes it the ultimate companion for public transport. In many cities, full-size scooters are banned from buses or trains during peak hours because they take up too much space. The 4Flex, when folded, is barely larger than a skateboard. You can tuck it between your legs on the subway, slide it under the seat on a bus, or place it on the luggage rack of a train. It eliminates the friction of "multi-modal" commuting. You no longer have to worry about where to put your scooter; it fits everywhere.

There are some practical limitations, of course. The lack of a kick-to-start requirement (on some modes) means you can zip away instantly, but the small wheels mean you can't hop curbs. You have to stop and lift the scooter. But again, because it weighs less than 10 kg, lifting it over a curb is effortless. The optional backpack specifically designed for it allows you to carry the scooter on your back, leaving your hands completely free-a scenario that is impossible with 99% of other scooters. It is the definition of "grab and go" mobility.

General Assessment

The general consensus among the community and owners of the WEGOBOARD 4Flex is that it is a brilliant, albeit niche, solution. It is widely praised for delivering exactly what it promises: extreme portability. Users love that it solves the storage problem in small apartments and the transport problem on crowded trains. It is often described as a "liberating" device because it removes the bulk associated with electric commuting. The removable battery is frequently cited as a favorite feature, both for the charging convenience and the ability to extend range.

However, the community is also honest about the trade-offs. It is not seen as a rugged, all-terrain vehicle. Some users have noted that the complex folding mechanism, with its multiple hinges and latches, can develop play over time if not maintained or if treated roughly. There are occasional reports of the ride being harsh on very bad roads, which is expected given the wheel size. But overall, the sentiment is positive because the scooter doesn't pretend to be something it's not. It doesn't claim to be an off-road beast; it claims to be a compact city commuter, and it excels at that.

It occupies a unique spot in the market. It's not a "toy" scooter, but it's not a heavy-duty cruiser. It's a precision tool for a specific type of problem. If you prioritize ride quality above all else, you might be disappointed. But if you prioritize convenience, weight, and the ability to take your scooter literally anywhere, the 4Flex is often regarded as the best-and sometimes the only-option in its class.

Who Is This Scooter For?

The WEGOBOARD 4Flex is the perfect match for the "hybrid commuter." This is the person who takes a train or bus for the majority of their journey but needs a fast way to cover the 2 or 3 kilometers from the station to the office. It is ideal for city dwellers living in upper-floor apartments without elevators, where carrying a 15 kg scooter up stairs twice a day would be a deal-breaker. It is also fantastic for students who need to stash their ride under a lecture hall desk or in a small dorm room.

It is also an excellent choice for RV owners and boaters. Because it folds down so small, you can easily stash two of them in the storage compartment of a camper van or a boat, giving you mobility when you dock or park without taking up valuable living space. It's great for people who want to keep a scooter in the trunk of their car "just in case" for running errands in the city center without paying for parking.

Who is it not for? It is not for the speed demon who wants to race cars at 40 km/h. It is not for the rider who has a 15 km one-way commute on pothole-ridden roads or gravel paths. It is not ideal for very heavy riders (approaching or exceeding 100 kg) who live in very hilly areas, as the 250 W motor will struggle on steep inclines. If you have a garage and don't need to carry your scooter, you can get more performance for your money with a larger, heavier model. But for the space-conscious urbanite, the 4Flex is in a league of its own.

Community Feedback - Pros

• Incredible Portability: Consistently cited as the number one advantage; fits in bags, trunks, and lockers easily.
• Featherweight: At 9,5 kg, it is easy for almost anyone to carry up stairs or onto public transport.
• Removable Battery: Users love the ability to charge the battery separately and carry a spare for double range.
• Suspension: Surprisingly effective front shock absorbers that make the ride smoother than expected for small wheels.
• Charging Speed: The battery charges fully in just 2-3 hours, which is very convenient for daily use.
• Adjustable Height: The telescoping stem allows riders of different heights to find a comfortable position.
• Legal Compliance: Comes with necessary lights and speed limits to be street legal in strict regions like France.
• USB Port: Some versions include a USB port to charge a phone while riding, a feature users find handy.
• Aesthetics: Owners appreciate the sleek, technical look and the "cool factor" of the folding mechanism.

The aspect that users rave about the most is undoubtedly the freedom the size affords them. Many reviews mention the relief of not being denied entry to a bus or a shop because the scooter is too big. The "origami" fold is a party trick that never gets old, but more importantly, it turns the scooter from a vehicle into an accessory. The removable battery is the close second favorite feature, solving the "charging logistics" nightmare that many apartment dwellers face.

Community Feedback - Cons

• Small Wheels: 5-inch solid tires can get stuck in large potholes and offer less grip on wet surfaces.
• Ride Harshness: Despite suspension, the ride can be rattly on cobblestones or very rough pavement.
• Folding Complexity: The 4-step fold takes longer than a standard 1-step fold and has more parts that can loosen over time.
• Limited Range: Heavier riders report getting significantly less than the advertised 20 km range.
• Hill Climbing: The 250 W motor struggles with steep inclines, requiring kick assistance.
• Stability: The narrow handlebars and small wheels can feel twitchy at maximum speed for inexperienced riders.
• Foot Brake: Some users dislike the rear mechanical brake, preferring a hand-operated disc brake (though the front brake is electronic).
• Kickstand: Some users find the kickstand a bit flimsy or tricky to deploy on uneven ground.

The most common complaint revolves around the trade-off of the wheels. Users quickly learn that they cannot ride the 4Flex like a mountain bike. You have to scan the road. The "fragility" mentioned in some reviews usually refers to the folding latches; because there are so many joints, they need to be kept tight. If a user neglects maintenance, the stem can develop a wobble. However, most owners seem to accept these downsides as the necessary price to pay for having the most compact scooter on the market.

Value for Money

At a price point typically hovering around 604 €, the WEGOBOARD 4Flex is not the cheapest scooter on the market, nor is it the most expensive. If you look purely at the raw specifications-250 W motor, 20 km range-you might think it's overpriced compared to some generic, heavy scooters that offer more power for less money. However, value is not just about watts per euro. With the 4Flex, you are paying for the engineering, the miniaturization, and the specialized folding mechanism.

When you compare it to other ultra-portable carbon fiber scooters or specialized "last mile" devices, the price is actually quite competitive. Many scooters in this weight class (under 10 kg) are either flimsy toys that break in a month or high-end carbon fiber units that cost over 1 000 €. The 4Flex strikes a balance, offering a durable aluminum build and reliable electronics at a mid-range price. The inclusion of the removable battery system adds significant value, as it extends the lifespan of the product (you can just buy a new battery when the old one degrades, rather than trashing the scooter).

Is it worth the investment? If you need the portability, absolutely yes. There is almost nothing else that does exactly what this scooter does at this price point. If you don't need the portability and just want a scooter for fun, you can get better performance for the same money elsewhere. But for the specific problem it solves-commuting in a crowded, multi-modal city environment-it offers excellent value.

About the Brand

WEGOBOARD is a French brand based in the Paris region, which gives it a significant advantage over generic dropshippers for European customers. They have established a reputation for being a serious player in the electric mobility sector, offering a wide range of scooters, hoverboards, and bikes. Unlike faceless overseas sellers, WEGOBOARD has physical workshops and a customer service team that you can actually call. This is crucial when you need spare parts or repairs.

The 4Flex is developed in partnership with HX, a well-known manufacturer in the scooter industry (often associated with the HX X6 or X7 models). This partnership combines HX's manufacturing expertise with WEGOBOARD's local support, quality control, and compliance with European regulations. The brand is known for ensuring their scooters meet strict French laws regarding lighting and speed limits.

Community experience with the brand is generally positive regarding support. Having a 2-year warranty (and 1 year for the battery) from a company with a domestic address provides peace of mind. They are also known for selling spare parts like batteries, chargers, and tires directly on their website, which makes long-term ownership much easier. If you are interested in their lineup, you can check out the WEGOBOARD brand page for more models.

Known Alternatives

If the WEGOBOARD 4Flex doesn't sound like the perfect fit, perhaps because you want larger wheels or don't need the extreme folding capability, there are several other options to consider. The CIRCOOTER Mate is a robust alternative that often offers a slightly more substantial ride feel, though it sacrifices the ultra-compact nature of the 4Flex. It's a good choice if you have a bit more storage space and want a more traditional scooter feel.

For those looking for a different balance of features, the CECOTEC BONGO V55 2X2 CONNECTED offers a different approach to urban mobility, often focusing on connectivity and power. If budget is a primary concern and you are willing to carry a bit more weight, the KUGOO KuKirin HX Pro is a strong contender, often providing higher specs for the price, though it lacks the refined portability of the 4Flex. The HOVER-1 Night Owl and APRILIA eSR2 are also worth checking out; the Aprilia in particular offers a very stylish design that appeals to the fashion-conscious rider, much like the 4Flex, but with a more standard form factor.

Ultimately, the choice comes down to how much you value the "fold-in-four" feature. If that is your priority, the 4Flex stands alone. If you are open to standard folding scooters, these alternatives might offer different benefits in terms of range or ride comfort.
