About

If you have been lurking in the electric scooter scene for more than five minutes, you have undoubtedly come across the name Hiboy. They are the titans of the budget-friendly commuter market, essentially taking the blueprint of the world's most popular scooters and asking, "How can we make this punchier and less prone to maintenance headaches?" The HIBOY KS4 Pro is the answer to that specific question. It represents a significant evolution in their lineup, designed to sit comfortably between the ultra-lightweight entry-level models and the heavy, expensive performance beasts. It is positioned as the "daily driver" for the pragmatic urbanite-someone who wants to get to work on time without wrestling with tire levers on the side of the road. The philosophy behind the KS4 Pro is clearly one of "robust utility." While many manufacturers are chasing the highest top speeds or the wildest suspension geometries, Hiboy has doubled down on reliability and user-friendliness. This scooter isn't trying to be a racing machine; it is trying to be the best possible version of a last-mile solution. It features a stronger frame, a more powerful motor than its predecessors, and a design that screams durability. It is built for the rider who needs a dependable tool, not a toy. In the broader market, the KS4 Pro is a direct challenger to the mid-range commuter segment. It takes aim at riders who might feel the standard 250W or 350W scooters are just a bit too sluggish for modern city traffic but aren't ready to drop 1 000 € on a high-end rig. By offering a 500W motor and a high-visibility lighting package, Hiboy is essentially saying, "Here is a scooter that can actually keep up with you." It is an inviting machine that bridges the gap between recreational fun and serious transportation.

Safety

When we talk about safety on two wheels, stopping power is invariably more important than going power. The HIBOY KS4 Pro employs a dual braking system that provides a reassuring level of redundancy. On the rear wheel, you have a mechanical disc brake. This is the kind of brake that gives you tactile feedback; you squeeze the lever, the caliper bites the rotor, and you feel the friction slowing you down. It is reliable and works well even in less-than-ideal conditions. Simultaneously, the front wheel utilizes an electronic regenerative brake (e-ABS). This uses the motor's resistance to slow the scooter down while trickling a tiny bit of energy back into the battery. The combination means that when you need to stop in a hurry, the scooter sits down and stabilizes rather than skidding out of control. Visibility is another massive component of safety, especially for commuters who might be riding early in the morning or late at night. The KS4 Pro is equipped with what Hiboy calls a "three brilliant lights system." This isn't just marketing fluff; it includes a bright headlight to illuminate the road ahead, a taillight that flashes when braking to alert traffic behind you, and-crucially-integrated side lights or ambient lighting. Being seen from the side is often overlooked by scooter designers, but it is vital when crossing intersections. The high positioning of the headlight on the handlebars also helps cast the beam further down the road, giving you more reaction time to spot potholes or debris. Stability at speed is the final pillar of safety here. The scooter runs on 10-inch tires. In the scooter world, the jump from 8.5-inch to 10-inch wheels is significant. Larger wheels roll over obstacles more easily and are less likely to get caught in small potholes or tram tracks. While we will discuss the comfort aspect of these tires later, from a safety perspective, the honeycomb solid tire design means you will never experience a blowout at high speed. A sudden flat tire at 30 km/h can be dangerous; with the KS4 Pro, that risk is mathematically zero. This reliability adds a mental layer of safety, allowing the rider to focus on the traffic rather than the road surface condition.

Performance

Let's talk about what happens when you press that thumb throttle. The KS4 Pro is equipped with a 500W brushless rear motor that can peak at a substantial 750W. For a scooter in this weight class, that is a generous amount of power. Unlike entry-level scooters that struggle to push you off the line, the KS4 Pro has a "reactive" feel. It's not going to tear your arms out of their sockets like a dual-motor hyper-scooter, but it has a satisfying zippiness that makes navigating city traffic genuinely fun. Acceleration is smooth and linear, meaning you don't get that jerky "on/off" feeling that plagues cheaper controllers. You can confidently pull away from cyclists at traffic lights. The top speed is capped at approximately 30 km/h (19 mph). For most urban environments, this is the "Goldilocks" speed-fast enough to cover ground efficiently and keep up with bicycle lane traffic, but not so fast that it feels terrifyingly unstable. Riders consistently report that the scooter feels planted and secure at this top speed. The cruise control feature is a nice addition here; once you hold a steady speed for a few seconds, the scooter takes over, reducing thumb fatigue on those long, straight stretches of bike path. It allows you to relax your grip slightly and enjoy the ride. Hill climbing is where the 500W motor really distinguishes itself from the 350W crowd. The manufacturer claims it can handle a 15-degree slope, and real-world testing largely backs this up for average-weight riders. If you are approaching the maximum load limit, you might see a drop in speed on steeper inclines, but for the standard bridge crossing or driveway incline, the KS4 Pro chugs along without stalling. It eliminates the "scooter of shame" moment where you have to kick-push to help the motor up a hill. While it is a single-motor machine, the peak power delivery ensures that it doesn't feel anemic when the terrain gets vertical.

Design

Visually, the HIBOY KS4 Pro strikes a balance between sleek modernism and industrial ruggedness. It sports a matte black finish that looks professional and stealthy, accented with subtle red touches on the cables and brake calipers that give it a sporty flair. It doesn't look like a toy; it looks like a piece of transportation equipment. The frame feels substantial, constructed from durable aluminum alloy. The cabling is reasonably well-managed, with much of it routed internally through the stem, which reduces the risk of snagging wires and gives the whole unit a cleaner, more premium silhouette. The folding mechanism is a critical design element for commuters, and Hiboy has implemented a "one-step" folding system. You unlock the safety collar, pull the lever, and the stem folds down to latch onto the rear fender. It is intuitive and quick, taking only a few seconds to transition from riding mode to carrying mode. The folded dimensions (approx. 115 x 42 x 49 cm) are compact enough to slide under a desk at the office or fit into the trunk of a compact car. The latching mechanism feels secure, which is reassuring because a wobbly stem is the bane of any scooter rider's existence. One unique aspect of the design is the integration of the display. The smart LED dashboard is large, bright, and centrally mounted. It avoids the "cheap calculator" look of some competitors, offering clear readouts of speed, battery life, and riding mode. The deck (the part you stand on) is covered in a rubberized grip tape that is easy to clean and provides excellent traction for your shoes. The overall build quality feels tight, though as with many mass-produced scooters, users recommend checking and tightening screws after the first few rides to ensure everything settles in perfectly.

Comfort

Comfort on the KS4 Pro is a topic of much debate in the community, and it largely centers around the tires. The scooter uses 10-inch honeycomb solid tires. The "honeycomb" refers to the holes drilled through the rubber sidewalls, designed to allow the tire to compress slightly and mimic the feel of air. The massive advantage here is maintenance: you will never, ever get a flat tire. However, the trade-off is that solid tires simply cannot absorb high-frequency road vibrations as well as pneumatic (air-filled) tires. On smooth asphalt, the ride is glassy and sublime. On rough cobblestones or cracked pavement, you are going to feel the road texture through the handlebars. To combat the stiffness of the solid tires, Hiboy has equipped the KS4 Pro with a rear shock absorber. This suspension unit does a valiant job of taking the edge off larger bumps. When you hit a transition in the sidewalk or a small pothole, the rear spring compresses to prevent that harsh jolt from travelling straight up your spine. Riders report that while the suspension is on the stiffer side, it is absolutely necessary and makes a noticeable difference compared to rigid scooters. It prevents the ride from feeling "bone-jarring," turning sharp impacts into manageable thuds. The standing position is quite comfortable thanks to the reasonably spacious deck. It allows most riders to find a comfortable stance, whether that's feet side-by-side or in a skateboard-style configuration. The handlebars are of a fixed height, which is standard for this category, but they are positioned at a level that works well for riders between 160 cm and 185 cm. The grips are rubberized and ergonomic, helping to reduce hand fatigue on longer journeys. While it might not be a "cloud-like" ride, it is a practical and acceptable level of comfort for city commutes where the road surface is generally decent.

Range

The manufacturer states a maximum range of up to 40 km (25 miles) on a single charge. As a savvy enthusiast, you should always treat manufacturer range estimates with a healthy dose of skepticism-they are usually tested with a light rider, on a flat indoor track, at low speeds. However, the KS4 Pro packs a 36V 11.6Ah battery, which offers a capacity of roughly 417 Watt-hours. This is a respectable tank size for a commuter scooter. In the real world, range varies heavily based on rider weight, terrain, temperature, and how aggressive you are with the throttle. Community feedback and independent tests suggest that a realistic range for a mixed commute (using top speed mode and encountering some hills) is closer to 25 km to 30 km. If you ride conservatively in "Eco" mode, you can certainly push closer to that 35-40 km mark. For the average person with a 10 km commute to work, this means you can easily do a round trip with plenty of juice to spare, or perhaps only charge it every couple of days. Charging time is listed between 5 to 7 hours. This is fairly standard for a battery of this size. It means you can plug it in when you get to the office and have a full battery by the time you clock out, or plug it in overnight at home. The charger is a standard brick similar to a laptop charger. The display gives you a battery bar readout, and while it gives a general idea of remaining power, seasoned riders know that voltage sag (the battery bar dropping when you accelerate and bouncing back when you stop) is normal behavior for this battery technology.

Use and Practicality

Daily usability is where the KS4 Pro shines as a pragmatic choice. First, let's address the weight. At approximately 17,5 kg, it is not a featherweight. It is heavier than the ultra-light carbon fiber scooters of the past, but lighter than the dual-motor performance models. Most average adults can lift it into a car trunk or carry it up a flight or two of stairs, but you probably wouldn't want to carry it up to a 5th-floor walk-up apartment every single day. The weight is a trade-off for the sturdy build and the larger battery. The folding mechanism and compact size make it excellent for multi-modal commuting. If you take a train or a bus, the KS4 Pro folds down neatly. The stem locks into the rear fender, creating a solid handle for lifting. This is a crucial feature that some expensive scooters miss. It fits easily under subway seats or in the corner of a coffee shop without being obtrusive. The inclusion of a kickstand is standard, but it's worth noting it's sturdy enough to hold the scooter up reliably. The IPX4 water resistance rating is another practical feature. This means the scooter is resistant to water splashes from any direction. While you shouldn't go deep-sea diving with it or pressure wash it, it can handle riding through a light drizzle or over wet pavement after a rainstorm without frying the electronics. This is essential for a commuter vehicle that might get caught in unpredictable weather. The app integration also adds practicality, allowing you to lock the scooter digitally (adding resistance to the motor so it can't be easily rolled away) and customize ride settings like cruise control and acceleration strength.

General Assessment

The general consensus in the electric scooter community is that the HIBOY KS4 Pro is a "high-value workhorse." It consistently garners high ratings across major retail platforms and enthusiast forums. Owners appreciate that it delivers exactly what it promises: a reliable, reasonably fast, and low-maintenance ride. It is often cited as one of the best "bang for your buck" scooters on the market, offering features usually found on more expensive models, such as the rear suspension and app connectivity. While there are some complaints-mostly centered around the ride firmness due to the solid tires or the occasional screw needing tightening-the overwhelming sentiment is positive. People love that they don't have to worry about tire pressure or punctures. They love the aesthetic, which feels more premium than the price tag suggests. The customer service from Hiboy also receives frequent praise, with reports of the company being quick to send out replacement parts or assist with troubleshooting, which is a rarity in the budget scooter world. Essentially, the KS4 Pro is viewed as a safe bet. It's not an experimental prototype; it's a refined version of a proven formula. It holds up well over time, with many users reporting thousands of kilometers logged with minimal maintenance beyond basic cleaning and brake adjustments. It has carved out a niche as the "sensible" choice for riders who value uptime and consistency over raw adrenaline.

Who Is This Scooter For?

This scooter is tailor-made for the **urban commuter**. If you live in a city, have a commute of 5 to 15 km, and want to bypass traffic jams and public transport schedules, this is your machine. It is perfect for the office worker who wants to arrive without being sweaty (thanks to the effortless electric power) and store the ride under their desk. It is also fantastic for **college students** who need to zip across large campuses quickly; the durability means it can survive the semester without constant trips to a repair shop. The KS4 Pro is also an excellent choice for **first-time scooter owners**. The power is manageable, the stability is good, and the maintenance-free tires remove the biggest barrier to entry for new riders (tire changes). It is user-friendly enough that you can learn to ride it in five minutes, but capable enough that you won't get bored of it after a week. However, this scooter is **not** for off-road enthusiasts or adrenaline junkies looking for highway speeds. If you plan to ride primarily on dirt trails, gravel, or extremely potholed roads, the solid tires will make for a miserable experience, and you should look for a scooter with large pneumatic tires and dual suspension. Similarly, if you need to carry the scooter up five flights of stairs daily, you might want to look for something in the sub-13 kg category, though you will likely sacrifice range and power to get there.

Community Feedback - Pros

Responsive Customer Support: Many users report positive interactions with Hiboy support for warranty issues.

The most consistently praised aspect of the KS4 Pro is undoubtedly the **peace of mind provided by the tires**. In the world of electric scooters, flat tires are the number one complaint and the biggest hassle. Changing a small scooter tube is notoriously difficult. Owners of the KS4 Pro express massive relief knowing they can ride through glass, debris, and rough patches without the fear of being stranded. Combined with the surprisingly punchy motor that handles hills well, users feel they have a reliable tank of a scooter that is always ready to go.

Community Feedback - Cons

Rough Ride on Bad Roads: Solid tires transmit vibrations; users note that cobblestones or large cracks are felt in the hands and feet.
Stiff Suspension: While present, the rear shock is described by some as quite stiff, needing a heavy rider to really activate it.
Weight: At 17,5 kg, some users find it heavier than expected for carrying on public transit.
Realistic Range: Like all scooters, the real-world range at full speed is lower than the advertised 40 km.
Screw Maintenance: A common tip is the need to check and use thread-locker (Loctite) on handlebar screws as they can vibrate loose.
Display Visibility: Some users mention the display can be hard to read in direct, bright sunlight.
Brake Adjustment: The mechanical disc brake may require initial adjustment out of the box to stop rubbing or squeaking.
App Connectivity: Occasional reports of Bluetooth connectivity glitches with certain phone models.

The most significant drawback discussed by the community is the **vibration on rough surfaces**. There is no getting around the physics of solid rubber tires. While the honeycomb design helps, users are quick to point out that you will feel the road texture much more than on a pneumatic tire scooter. Many suggest wearing gloves to dampen the vibration in the handlebars or simply learning to bend your knees more when traversing rough patches. It is the accepted trade-off for the "no flat tire" benefit, but it is a deal-breaker for those living in areas with ancient, crumbling infrastructure.

Value for Money

At a price point hovering around 355 EUR, the HIBOY KS4 Pro represents exceptional value for money. When you survey the market, this price bracket usually gets you a 350W motor, a smaller battery, and no suspension. To get a 500W motor, a 36V 11.6Ah battery, and rear suspension for this price is aggressive pricing from Hiboy. They are effectively undercutting the major premium brands while offering 90% of the functionality. If you were to look for a scooter with similar specs from a high-end boutique brand, you could easily pay double. While you might get slightly better fit and finish or softer suspension on a more expensive unit, the KS4 Pro delivers the core experience-speed, range, and braking-at a fraction of the cost. It is an "economy" scooter that performs like a "mid-range" one. For the budget-conscious buyer, this is arguably one of the smartest investments. You aren't buying the absolute cheapest junk that will break in a month, but you aren't paying the "brand tax" of the most famous names either. You are paying for specs and utility. The low maintenance costs (no inner tubes to buy!) further enhance the long-term value proposition.

About the Brand

Hiboy has established itself as a dominant force in the entry-to-mid-level electric mobility market. They are not a boutique garage building custom racers; they are a high-volume manufacturer focused on getting electric transport into the hands of the masses. Their reputation is built on affordability and reliability. They are widely known for taking popular form factors and tweaking them to address common user complaints-most notably, their widespread adoption of solid tires to eliminate puncture anxiety. In the e-scooter world, Hiboy is often seen as the "Toyota Corolla" of brands. They might not be the flashiest or the fastest, but they are everywhere, parts are easy to find, and they get the job done. Their commitment to keeping prices low while slowly upgrading specs (like moving from 350W to 500W motors) shows they listen to market demands for more power. Community experience with the brand's support is generally better than average for Chinese export brands. While they operate largely online, users frequently share stories of receiving free replacement fenders, chargers, or controllers when things go wrong within the warranty period. This level of post-purchase support helps build trust and suggests that Hiboy is interested in long-term brand viability, not just quick sales.

Known Alternatives

If the HIBOY KS4 Pro doesn't tick all your boxes, there are several other scooters in this category worth considering. The market is crowded, and depending on whether you prioritize comfort, portability, or power, one of these might be a better fit. One strong contender is the VSETT VSETT MINI. VSETT is a brand known for high-performance enthusiasts' scooters, and the Mini is their entry into the portable commuter market. It typically offers a more refined suspension feel and a distinct design language that sets it apart from the sea of black commuter scooters. If build quality and brand pedigree are high on your list, the VSETT Mini is a fantastic alternative to investigate. Another direct rival is the ISINWHEEL S9PRO. This scooter often competes head-to-head with Hiboy in terms of specs and pricing. It usually targets the same demographic: commuters looking for solid tires and decent range without breaking the bank. It is worth comparing the current pricing and specific battery configurations between the S9PRO and the KS4 Pro, as they often trade blows during sales events. For those who might want something with a bit more of a robust feel or different suspension dynamics, the KAABO Skywalker 8H is an interesting option. Kaabo is famous for their "Wolf" line of beast scooters, and that DNA trickles down to their smaller models. The Skywalker series often prioritizes ride comfort and torque. Finally, if you are looking for something that leans slightly more towards the performance side of the spectrum, the MUKUTA Mukuta 10 Lite might be on your radar, offering a different take on the 10-inch tire commuter formula.
