Fast Answer for Busy Riders ⚡ (TL;DR)
The overall winner for most riders is the HIBOY S2 Pro thanks to its stronger motor, better brakes, larger wheels and more confidence at higher city speeds. It feels more like a "real vehicle" and less like a compromise, especially if you deal with bigger roads or steeper bridges.
The KuKirin S1 Max is the better pick if your priority is low price, easy carrying and multi-modal commuting - short hops, lots of stairs, trains, lifts. It's lighter on your shoulder and on your wallet, but also more limited in speed, braking feel and rough-road confidence.
If you want a more capable, future-proof commuter, lean Hiboy. If you want something cheap, compact and "good enough" for short, flat city runs, the KuKirin makes sense.
Now let's dig into how they really behave once you leave the spec sheet and hit real streets.
There is a particular charm in budget scooters that promise to replace your bus pass without demanding a second mortgage. The Hiboy S2 Pro and KuKirin S1 Max both live in that world: affordable, relatively light, and unapologetically aimed at people who just want to get to work - not win hill-climb trophies.
I've put plenty of kilometres on both: office commutes, late-night grocery runs, mildly irresponsible "let's see what happens if..." tests on bad pavements. They are strikingly similar in philosophy - solid tyres, modest batteries, simple frames - yet they approach daily life in very different ways. One leans harder into power and "grown-up scooter" vibes, the other into portability and price.
If you are torn between them, you are probably deciding what you can live without more than what you gain. Let's unpack that properly.
Who Are These For, and Why Compare Them?
Both scooters sit in the budget commuter segment: affordable entry points into electric mobility, designed for city speeds and relatively short daily distances. They share several traits: solid honeycomb tyres (no punctures, more vibration), compact folding designs, and range figures that are absolutely optimistic unless you weigh as much as a medium-sized backpack.
The Hiboy S2 Pro is the "budget scooter that wants to be taken seriously" - more motor grunt, bigger wheels, proper hand-operated disc brake, and app features. It suits riders who want one scooter to do most things reasonably well and aren't obsessed with shaving every last kilogram.
The KuKirin S1 Max is the "last-mile specialist" - lighter, cheaper, with enough battery to do a decent commute, but clearly tuned for portability and simplicity. It's for people who regularly mix riding with trains, lifts and stairs, and care more about convenience than raw performance.
They're direct competitors because they target the same rider profile: first-time or budget-conscious commuters who don't want punctures, don't want overly complex machines, and think spending four figures on a scooter is... ambitious.
Design & Build Quality
Park them side by side and the family resemblance to the rest of the budget market is obvious, but their personalities are different.
The Hiboy S2 Pro looks and feels like a beefed-up Xiaomi-style commuter: fairly thick stem, solid deck, and a stance that says "I'm here to work, not pose." The matte frame with red accents is easy on the eye, and the cabling is reasonably tidy. The folding joint feels reassuringly chunky - more "commuter vehicle" than toy - though you do want to periodically check for play in the stem over time. The rear fender has a metal brace, which is a polite way of admitting that budget fenders break if you don't overbuild them a bit.
The KuKirin S1 Max takes a more stripped-back approach. Slimmer frame, narrower bars, smaller wheels: the whole scooter feels closer to the "light utility tool" end of the spectrum. The one-key folding system is very commuter-friendly - quick, simple, no wrestling with stubborn clamps. The overall construction is decent for the price, but it doesn't feel quite as substantial underfoot as the Hiboy. Think sturdy enough for daily city use, but you won't mistake it for a premium machine.
In the hand, the difference is obvious: the Hiboy feels more solid, the KuKirin more nimble. Neither is what I'd call luxurious - they both still scream "budget scooter" in the finer details - but the Hiboy has the more confidence-inspiring chassis, while the KuKirin clearly optimises for lightness and easy handling.
Ride Comfort & Handling
Both brands have made the same deal with the devil: solid honeycomb tyres in exchange for never having to curse a puncture again. The bill arrives in the form of vibrations.
On the Hiboy S2 Pro, the larger wheels and rear dual springs save the day more often than you'd expect. On smooth tarmac it cruises comfortably; on typical patchy city asphalt it stays acceptable. Hit broken pavement or cobblestones, and the scooter reminds you very quickly that airless tyres don't forgive. After several kilometres on really rough surfaces, your knees and ankles will be filing complaints. However, the steering feels stable, the deck is reasonably roomy, and at higher speeds it tracks straight without drama - which makes it less tiring mentally.
The KuKirin S1 Max has both front and rear suspension, which sounds great on paper until you remember the wheels are smaller. The ride is very "talkative": you feel every texture of the road, just slightly softened. Over mild cracks and joints, the suspension does its job; over larger defects you're reminded that physics always wins. The narrow handlebar makes it agile at low speed - weaving through pedestrians and parked cars is easy - but at top speed the twitchiness of small wheels plus narrow bars means you need a steady hand.
In real terms: the Hiboy is the more composed scooter once you get above jogging pace or ride on mixed surfaces; the KuKirin feels more lively and compact, but also more nervous when the ground or speed stops being perfect.
Performance
Neither of these is a rocket, but one definitely feels less bored with life.
The Hiboy S2 Pro has the stronger motor and it shows. Off the line it steps forward with a satisfying shove, enough to pull away from rental scooters and lazy cyclists without needing to lean forward like you're launching a dragster. It carries its top city speed with more authority, and on gentle hills it keeps going in a way that cheaper 250-350 W class scooters often don't. You still feel the motor working on steeper inclines - this is not a mountain goat - but you don't have to shamefully kick your way up every bridge.
The KuKirin S1 Max is noticeably milder. Acceleration is smooth and quite civilised, which is nice in tight spaces but uninspiring if you're in a hurry. It tops out at the typical EU commuter speed and feels fine there, but you don't have much reserve left - you're basically at the edge of what those wheels and that frame should be doing anyway. On hills, it's very terrain and rider-weight dependent: gentle inclines are fine, anything more and your right foot becomes a supplementary propulsion system.
Braking is where the philosophy split becomes really obvious. The Hiboy's combination of rear disc brake and front regenerative braking gives you proper lever feel and much more confidence. Grab a firm handful and it will haul you down from speed with decent authority for this class.
The KuKirin relies on a front electronic brake and a rear foot brake on the fender. Once you're used to it, you can manage okay, but it requires a deliberate riding style and doesn't feel as precise or confidence-inspiring, especially in emergency situations. Having to stomp a fender when a car cuts across you is... not my favourite modern invention.
So in the performance chapter: Hiboy for people who value stronger acceleration, better brakes and a bit of hill-climbing grunt; KuKirin for people who are happy with "gets me there" performance and prioritise a gentle, controlled ride over any kind of excitement.
Battery & Range
Both manufacturers quote ranges that clearly assume a fairy-light rider cruising gently on perfectly flat terrain. Real-world riding paints a familiar picture.
The Hiboy S2 Pro carries a slightly larger battery and pairs it with a stronger motor. In practice, ridden energetically in its faster mode, you're looking at a comfortable there-and-back for most typical urban commutes with a bit left for detours - roughly a solid workday of normal city use, not an all-day touring machine. Ride in a more restrained mode and you can stretch it, but then you're deliberately not using the extra power you paid for.
The KuKirin S1 Max squeezes impressive real-world distance out of its battery considering the price and weight. With its tamer motor it's pretty efficient: for flat-city commuters doing moderate speeds, it can easily cover the usual office run plus errands without needing a midday top-up. It doesn't really beat the Hiboy noticeably in range; it just manages to hang surprisingly close despite being cheaper and lighter.
Charging is another small difference. The Hiboy fills up in a mid-range time window that works well for overnight charges or a long office stint. The KuKirin takes longer relative to its battery size, so you're definitely in the "charge overnight and forget" camp rather than "quick boost over lunch". For most users that's acceptable, but fast it is not.
Overall: the numbers are similar enough in real life that range shouldn't be the deciding factor unless you really sit at the far end of the claimed spectrum. Both are fine for typical city commutes; neither is a distance monster.
Portability & Practicality
This is where the KuKirin starts to feel smug.
The KuKirin S1 Max is clearly designed with stairs, trains and car boots in mind. It's lighter in the hand, folds quickly with a simple mechanism, and packs down into a neat, compact bundle that doesn't make you feel like you're smuggling a small moped onto the metro. Carrying it up a few flights of stairs is not fun, but it's very doable for an average adult without turning every commute into leg day.
The Hiboy S2 Pro is a chunkier proposition. The folding action is straightforward and secure, but once folded it's a more substantial object - longer, heavier, and slightly more awkward in tight spaces. Carrying it occasionally is fine; doing it every day up multiple flights is where the charm wears off quickly. As a "store it in the hallway, roll it into the lift, maybe put it in the car trunk sometimes" scooter, it works great. As a multi-modal companion you constantly haul around, it's clearly less friendly.
On the maintenance side, both win big with their solid tyres: no punctures, no Sunday-morning tyre wrestling sessions. The Hiboy's disc brake brings with it occasional adjustment and the familiar potential for squeaks, whereas the KuKirin's brake setup has fewer mechanical parts to tweak, but you pay with less refined braking feel.
If your daily life involves lifting and folding constantly, the KuKirin is easier to live with. If you mostly roll from door to door with only occasional carrying, the Hiboy's extra bulk is a fair trade for the more capable ride.
Safety
Safety on budget scooters is always a mix of "what the scooter offers" and "what the rider compensates for." These two make different compromises.
The Hiboy S2 Pro scores well on the fundamentals: proper mechanical rear brake plus electronic front assistance, larger wheels for better stability over potholes, and a surprisingly complete lighting package including headlight, tail-light and side visibility. At legal-ish city speeds it feels reasonably planted, and emergency stops - while never spectacular on small wheels - at least feel predictable.
Its weak points are mainly the solid tyres' grip in the wet and the occasional reports of stem play developing with heavy use if you ignore basic bolt checks. On damp tarmac or painted lines you absolutely need to dial down your enthusiasm; solid rubber is simply not as forgiving as air.
The KuKirin S1 Max is more of a mixed bag. It has workable lights and decent water splash protection for light rain, but the braking concept is old-school: soft-feeling front electronic brake plus a rear foot brake that demands practice and correct body position. For experienced riders, that's manageable; for beginners, it can be a learning curve you'd rather not climb when a car door opens in front of you.
The smaller wheels also mean that at its top speed, every crack in the road feels a bit more relevant. Hit a deeper pothole you didn't see and you'll feel it in your wrists - and possibly your heart rate. On smooth cycle paths, it's fine; on neglected city streets, you need to stay very alert.
If safety is high on your list, the Hiboy's combination of braking hardware, wheel size and lighting simply adds up to a more reassuring package, provided you respect the solid tyres in wet conditions.

Price & Value
Let's address the elephant in the room: the KuKirin is significantly cheaper. That alone will make many riders lean in its direction.
The KuKirin S1 Max gives you a decent-sized battery, dual suspension, puncture-proof tyres and a truly portable package for the price of a mid-range smartphone. In the world of budget scooters, that is hard to argue with. Of course, you're not getting cutting-edge components or luxurious feel, but per euro spent it delivers a lot of utility.
The Hiboy S2 Pro asks for noticeably more money in exchange for a stronger motor, larger wheels, disc brake, better lighting and a more mature overall ride. The question is whether those upgrades justify the premium for you. If you care about performance, braking confidence and "this actually feels like a proper vehicle", then yes, the extra spend makes sense. If your rides are short, flat and gentle, the KuKirin's cheaper ticket is very tempting.
Value-wise, both are strong in their own lanes: KuKirin wins on pure budget impact, Hiboy wins on capability per euro. Long-term, though, the Hiboy's better braking and power may age more gracefully as your confidence and expectations grow.
Service & Parts Availability
In the budget world, service is often "DIY with YouTube", and these two are no exception.
Hiboy has a huge presence online and a large user base, which means plenty of tutorials, third-party parts and community knowledge. Official support, though, can be hit-or-miss in responsiveness. Common wear items - tyres (solid, so rarely), brakes, controllers - are widely available, but you should be prepared to spin a few tools yourself rather than rely on a dealership network.
KuKirin / KUGOO also benefits from a broad distribution network, particularly across Europe, with warehouses that help with shipping and parts availability. Service centres exist, but again, the experience varies. The S1 Max is simple enough mechanically that most owners end up tightening bolts, swapping parts and fixing minor issues on their own, with the internet as their workshop manual.
Neither brand truly shines in white-glove support, but neither is a mysterious no-name either. For European riders, KuKirin's distribution setup has a slight edge in logistics; Hiboy has a slight edge in sheer community size and documentation.

Final Verdict - Which Should You Choose?
If we're picking a single "winner" for the average urban rider, it's the HIBOY S2 Pro. It simply feels more like a proper vehicle: stronger motor, better braking hardware, larger wheels and slightly more composed behaviour at speed. If you commute on real city streets - mixed surfaces, unpredictable traffic, the odd hill - those traits matter more and more over time.
The KuKirin S1 Max makes a strong case if your world is mostly short, flat, and interspersed with stairs, train platforms and office lifts. It is cheaper, easier to carry, and still covers a respectable daily distance. As a first taste of electric commuting or a compact second scooter, it does its job well enough, provided you accept the softer braking and firmer ride.
Here's the simple way to decide: if you want something that you can grow into a bit - faster, more stable, better stopping - go Hiboy. If you know your rides are short, flat and you care more about budget and portability than anything else, the KuKirin is the pragmatic, if slightly less confidence-inspiring, choice.
