Fast Answer for Busy Riders ⚡ (TL;DR)
The KuKirin S1 Max is the overall winner for most riders: it goes noticeably further on a charge, rides a touch softer thanks to suspension at both ends, and still stays reasonably portable. The Hiboy S2 fights back with sharper brakes, better lighting and a more mature app and support ecosystem, but its shorter real-world range and harsher ride hold it back as an all-rounder.
Choose the Hiboy S2 if your daily trips are short, you value strong braking and visibility, and you want solid customer support in a very compact package. Go for the KuKirin S1 Max if you need more range from a budget scooter and don't mind its old-school braking and slightly clunky software. Both will get you to work; the fun is in deciding which compromises you're willing to live with-so let's dig in.

Electric scooters at this price are not toys anymore-they are what a lot of people actually rely on to get to work, lectures, and the supermarket. The Hiboy S2 and KuKirin S1 Max sit right in that "sensible money, serious use" bracket, promising proper commuter performance without the "costs as much as a used car" drama.
On paper, they look like cousins: similar power, similar size, both with solid honeycomb tyres that laugh in the face of nails and glass while making your knees slightly less amused. In practice, they take two quite different approaches to the same problem: cheap, reliable urban transport that doesn't fall apart after a month.
The Hiboy S2 is the "app-happy commuter with good brakes and bright lights in a compact, office-friendly shell." The KuKirin S1 Max is the "range-first, no-frills mule that will drag you further with slightly less finesse." Let's see which one actually deserves a place in your hallway.
Who Are These For, and Why Compare Them?
Both scooters live in the entry-level to lower mid-range price band, the territory where most first-time buyers shop and where marketing promises often age badly after a winter of potholes. They're designed for people whose daily rides are measured in city blocks and bike lanes, not in forest trails.
They share a lot: modest single motors, commuter-friendly top speeds, solid tyres, basic suspension, and frames light enough to carry up stairs without writing your will first. They're also two of the most visible "no flat tyres, no nonsense" options in Europe, so they end up on the same shortlist constantly.
In other words: if you're shopping one, you're almost certainly looking at the other-and you should, because their trade-offs go in opposite directions.
Design & Build Quality
In the hand, the Hiboy S2 feels like someone photocopied a Xiaomi commuter scooter and then spent their budget on electronics and tyres rather than fancy metalwork. The frame is solid enough, but you can tell it's been engineered to hit a price point. The matte finish looks professional, the wiring is reasonably tidy, and the cockpit with its central display and dual brake controls feels "proper scooter" rather than toy-store special.
The KuKirin S1 Max, meanwhile, leans harder into industrial utility. The aluminium frame feels slightly chunkier, the accents are more "budget sports gear" than understated commuter, and the folding joint and stem have that familiar Kugoo vibe: not premium, but reassuringly overbuilt rather than delicate. Out of the box it tends to rattle a bit less than many cheap scooters, including some Hiboys I've ridden-though both will reward a spanner check after the first week.
Where the Hiboy clearly pulls ahead is in the details that touch your hands and eyes every day: the cockpit layout, the lever-based rear disc brake, the cleaner display and the generally more polished control scheme. The KuKirin counters with a simpler, faster folding mechanism and a deck that feels slightly more like you can throw it at a commute and not worry. Neither feels high-end, but both feel a step above the truly disposable stuff-and both still remind you occasionally why they were so affordable.
Ride Comfort & Handling
Let's be frank: both of these roll on solid honeycomb tyres. Comfort is never going to be their headline feature; "won't leave you stranded with a puncture" is the actual story here.
On the Hiboy S2, you get rear springs trying bravely to pretend they're a full suspension system. On smooth bike paths, it glides well enough. The moment you hit tired old city asphalt, expansion joints, or the cobblestone section that town planners included to annoy everyone equally, the ride gets busy. The rear suspension takes the sting off bigger hits, but the high-frequency buzz still reaches your hands and knees. Quick steering from the relatively narrow bars makes it nimble around pedestrians, but also a bit twitchy if the surface is sketchy.
The KuKirin S1 Max answers with suspension at both ends: a front shock and a rear spring. Before you picture a magic carpet-no. It still rides firmly; this is not a sofa on wheels. But on the same stretch of broken tarmac, the S1 Max does a marginally better job of rounding off the worst hits. The front end doesn't slap quite as hard over sharp edges, and overall it feels a touch more composed when the surface goes from "city bike path" to "WWII relic."
Handling-wise, they're very close: light, responsive, and best suited to urban speeds. The S1 Max can feel slightly more stable thanks to its front suspension and slightly more planted chassis, while the Hiboy's cockpit and stronger braking invite more confident corner entry-assuming the tyres still have grip. Neither likes deep potholes; at this wheel size, you learn to scan ahead or you learn to walk.
Performance
Both scooters use modest front hub motors in the same power class, and both are tuned for commuting rather than heroics. Think "keep up with city cyclists and embarrass lazy car drivers off the lights up to the next junction," not "drag race your friend on a dual-motor monster."
The Hiboy S2 feels a little more eager off the line in its sport mode. The throttle mapping is straightforward: you press, it goes, with a predictable and reasonably brisk build-up that lets you squirt through gaps in traffic without surprises. Top speed is a shade higher than the KuKirin's, and you do feel that extra headroom on open cycle paths-just enough to feel "fast" without feeling like you're auditioning for a crash compilation.
The KuKirin S1 Max answers with three speed modes tuned more conservatively. Acceleration is similarly smooth, but it feels a hair more restrained, especially in the middle mode, which a lot of riders end up using by default. At its top legal speed it feels comfortable enough, but you don't get that last tiny bit of shove the Hiboy offers. Where the S1 Max claws some pride back is in sustained performance: with its larger battery, it holds its pace better towards the end of the charge, where the Hiboy starts to feel a bit tired.
Hill climbing on both is "it'll cope with reasonable city gradients, but don't move to San Francisco." Light-to-average riders on typical European bridges and ramps will be fine; heavier riders on steeper stuff will see speeds sag on both. The Hiboy's slightly punchier take-off can feel nicer at the bottom of a slope, but the KuKirin's extra battery stamina helps a bit on longer drags.
Braking is where the personalities really diverge. The Hiboy's combination of electronic braking and rear disc, both engaged by the lever, gives you strong, confidence-inspiring stops-occasionally a bit too eager until you learn a delicate touch. The KuKirin uses motor braking at the front and an old-school foot brake at the rear. Used properly, it can stop acceptably, but it demands more technique and attention. In rain or panic situations, I'd much rather be on the Hiboy.
Battery & Range
This is the KuKirin S1 Max's big card. Its battery simply has more capacity, and you feel it. On mixed-speed city riding-some top-speed stretches, some slow navigation, a few stops-you can realistically expect it to cover commutes that would have the Hiboy nervously eyeing its last bar. You're not doing epic tours, but for ordinary daily use it lets you just ride without constantly calculating whether you can detour via the shop.
The Hiboy S2, by contrast, feels much more "last mile and a bit." Stay sensible with speeds and rider weight and it will usually handle a typical urban round trip, but push it hard in top mode or add hills and it drops off noticeably. For shorter commutes it's fine; once your daily target creeps into the higher teens of kilometres, you really want workplace charging or a very good idea of your consumption.
Charging is the one area where the Hiboy looks better on paper and in real life. It tops up notably faster from empty, which means lunchtime or mid-afternoon charges are viable. The S1 Max is more of an overnight drinker: plug it in when you get home, forget it until morning. The flip side is that you need to charge the S1 Max less often because of its greater range, so the slow fill is less painful than it sounds-as long as you don't routinely run it down to fumes.
Portability & Practicality
Both scooters are in that borderline-liftable category: not featherweights, but still manageable for stairs, trains and the office. The Hiboy S2 is the slightly lighter of the two, and you can feel that when you're carrying it one-handed up a flight or heaving it into a car boot. For smaller riders or those doing this multiple times a day, that difference is noticeable.
The KuKirin S1 Max, while a little heavier, makes up for it with a very quick, simple folding mechanism. You fold, it locks to the rear, and you're done in a couple of seconds. It feels designed for the "bus is arriving now" scenario. The Hiboy's fold is also straightforward but often stiffer when new, and the latch can demand a bit more persuasion. Both can develop a little play at the stem over time if you neglect bolt checks; neither is unique in that among budget folders.
In tight city living-small flats, under-desk storage, cramped lifts-the Hiboy's slightly trimmer size and lower weight give it the edge. If your commute includes a stairwell you already hate, the Hiboy is marginally less offensive. If you're constantly folding and unfolding to jump on and off trains, the KuKirin's faster mechanism feels easier to live with day after day.
Safety
On safety, we have a clear philosophical split.
The Hiboy S2 takes the modern approach: strong lever-activated braking that combines motor regen and rear disc, bright forward lighting, a solid rear light that reacts to braking, and side deck lights that actually make you visible from more than one angle. In night city riding, that extra light footprint is genuinely useful. The caveat is the solid tyres: grip on wet paint, metal covers and polished stone is... let's say "educational." You learn quickly to treat damp surfaces like they're made of soap.
The KuKirin S1 Max sticks with its e-brake plus foot-brake combination. Used with good technique-weight shifted back, firm foot on the fender-it stops adequately for its top speed, but it never feels as intuitively secure as a decent disc setup on the rear. The lighting is serviceable: a competent headlight and rear brake light that satisfy the basic needs of city commuting, but without the lateral visibility tricks of the Hiboy. On the other hand, the KuKirin's front suspension helps preserve tyre contact over rougher patches, which indirectly helps stability, especially when you're braking on bumpy surfaces.
Both scooters share the same core safety warning: small wheels plus solid tyres and rain are not best friends. The KuKirin's slightly better ingress protection rating is nice for peace of mind, but in either case you should treat heavy downpours as a good argument for public transport.
Community Feedback
| Aspect | HIBOY S2 | KuKirin S1 Max |
|---|---|---|
| What riders love | Strong dual braking, bright and flashy lighting, "never-flat" tyres, compact size, solid app with braking and acceleration tuning, responsive customer support and easy access to spares. | Big battery for the price, very practical range, zero-maintenance tyres, quick simple folding, decent dual suspension for the class, and the feeling of getting a lot of scooter per euro. |
| What riders complain about | Harsh ride on rough surfaces, slippery feel in the wet, real-world range well below the marketing figure, occasional stem wobble, throttle-related error codes, and rattly rear fenders. | Firm ride despite suspension, foot-brake learning curve, buggy or annoying app, dim display in bright sun, slow charging, and some reports of stem play developing over time. |
Price & Value
This is where both look tempting at first glance-and a bit less so once you factor in what you're actually getting over several seasons.
The Hiboy S2 undercuts the KuKirin S1 Max on sticker price. For very tight budgets, that alone is a strong argument. You're getting a complete commuter package with respectable speed, reasonable range for short hops, good brakes, decent suspension at the rear, and app customisation-at a price where a lot of competitors are still selling toys. As long as your daily distances are modest and your roads aren't medieval, you do get solid value per euro.
The KuKirin S1 Max costs more out of the gate, but gives you significantly more usable range and dual suspension without blowing up the weight. If this is going to be your main transport rather than just a station-to-office shuttle, that extra battery capacity is not a luxury-it's sanity. Measured over months of commuting, the slightly higher price can be a fair trade for not having to baby your battery or charge at every opportunity.
Neither feels like a rip-off. They both feel like exactly what they are: smartly specced budget scooters where you can see the corners that were cut. The KuKirin leans into range and basic hardware; the Hiboy leans into controls, app and support.
Service & Parts Availability
In Europe, both brands are better known than the usual random Amazon alphabet soup, which helps.
Hiboy has built a decent reputation for online support: warranty responses, replacement throttles, fenders and chargers actually turning up, and a large owner community sharing solutions. For a budget brand, that counts for a lot when you're staring at an error code on a Monday morning. The S2 family is widespread, so generic spares and compatible parts are easy to find.
Kugoo / KuKirin has strong distribution inside the EU and a big user base, especially in Central and Eastern Europe. Parts availability is generally okay, and there's no shortage of guides and videos on common fixes. Customer support experiences are more mixed: some riders report smooth warranty handling, others get the familiar "budget brand run-around." It has improved over the years, but I'd still score Hiboy a touch higher on the consistency of after-sales experience.

Final Verdict - Which Should You Choose?
If you strip away the marketing and look at how these scooters behave after a few hundred kilometres of mixed city abuse, a pattern emerges. The KuKirin S1 Max is the more capable transport tool for people who actually depend on a scooter every day, while the Hiboy S2 is the tidier, more polished gadget for shorter, simpler commutes.
If your daily ride is on the shorter side, mostly well-paved, and you care a lot about braking confidence, lights and app features-and you'd like a brand with a slightly better track record for customer support-the Hiboy S2 still makes sense. It's a decent "first real scooter" that fits in tight spaces, charges quickly, and won't spook you with its behaviour, as long as you respect its range and the limits of its solid tyres.
If, however, your route is longer, you don't want to think about charging at work, and you're willing to adapt to the foot brake and live with a so-so app, the KuKirin S1 Max is simply the more forgiving partner. Its bigger battery and dual suspension make it less fragile as a daily driver. It's not refined, but it gets the job done with fewer compromises once the novelty wears off and it just becomes "the thing that has to work every day."
Between the two, the KuKirin S1 Max edges ahead as the better all-round commuter-more range, better suspension balance, and enough practicality to justify the extra outlay. The Hiboy S2 remains a solid budget pick if you know exactly what you're buying and stay within its comfort zone.
