Fast Answer for Busy Riders ⚡ (TL;DR)
If you want a proper daily commuter that can replace buses or short car trips, the Hiboy S2 Max is the stronger overall scooter: more range, more power, bigger wheels and a calmer, more planted ride at higher speed. It feels more like a small vehicle than a gadget.
The KuKirin S1 Max makes more sense if your rides are short, you carry the scooter a lot, and you absolutely refuse to deal with punctures - think multi-modal commuter, student, or "last 3 km from the station" type usage. It's cheaper, lighter, and much easier to live with in walk-up buildings.
Both cut corners in different places, so the right choice depends on whether you value ride quality and range (Hiboy) or portability and low maintenance (KuKirin) more. Read on before you click "buy" - the trade-offs are bigger than the spec sheets suggest.
Stick with the full article and you'll finish with a very clear picture of which one will actually make your daily life better, not just your spreadsheet prettier.
Electric scooters have grown up. We're long past the era of wobbly toys with a battery; today even budget models promise "max" range, "max" comfort and "max" performance - usually for surprisingly "min" money. The Hiboy S2 Max and KuKirin S1 Max sit right in that sweet spot where most real riders shop: not crazy expensive, but ambitious enough to pretend they're serious transport.
I've spent a lot of kilometres on both, in the kind of conditions you'll actually ride in: wet bike lanes, broken pavements, too many traffic lights, and the occasional "shortcut" that turns into a cobblestone horror show. On paper they look like rivals. In reality, they solve very different problems - and both make some pretty questionable compromises to hit their price tags.
If you're trying to decide which "Max" will carry you and which will just carry marketing slogans, let's break it down properly.
Who Are These For, and Why Compare Them?
Both scooters live in the budget-to-lower-mid-price universe, aimed at people who want to commute, not set land-speed records. Neither is a street rocket; both hover around the legal city-speed range and are clearly built with commuters and students in mind.
The Hiboy S2 Max is the "I'm done with rental scooters, I want my own grown-up machine" choice. Bigger frame, bigger battery, bigger wheels - this is aimed at riders doing longer daily routes who want to replace a bus pass, not just shave five minutes off a walk.
The KuKirin S1 Max is very much the "last-mile and up the stairs" machine. It chases low weight and zero-maintenance tyres instead of plush comfort. If your commute involves trains, stairs, lifts and narrow hallways, this is the one that tries not to hate you.
They compete because they're often cross-shopped: similar nominal top speeds, both promising generous range and both marketed as "Max" commuters under the price of a cheap e-bike. But the type of rider who'll be happy with each one is quite different.
Design & Build Quality
In the flesh, the contrast is obvious before you even power them on.
The Hiboy S2 Max looks and feels like a scaled-down version of a full-fat commuter like the Ninebot Max. The stem is stout, the deck is reassuringly solid, and the whole scooter has that "one piece of aluminium" vibe. Cabling is mostly tucked away, the hinge feels beefy, and nothing screams toy. You do, however, get the sense that every euro went into battery and motor rather than refined touches - it's solid, but a bit utilitarian and slightly rough at the edges in terms of finishing.
The KuKirin S1 Max goes for skinny and functional. The frame is slimmer, the deck narrower, and everything feels more compact and purposeful... and a little more budget. The folding mechanism is quick and clever, but the stem and bars don't give the same "I'll take abuse for years" impression as the Hiboy. Long term, some riders report small play developing in the hinge if you don't keep an eye on it; it's fixable, but it's there.
In your hands, the Hiboy feels like a small vehicle; the KuKirin feels like well-made consumer electronics that happen to have wheels. Neither is outright badly built, but if I had to bet on which frame I'd want after a couple of years of knocks and kerb drops, it would be the Hiboy's.
Ride Comfort & Handling
This is where their philosophies clash hardest.
The Hiboy S2 Max rides on large, air-filled tyres with no real suspension to speak of. The result on decent tarmac is surprisingly smooth. Those big tyres swallow small cracks, manhole covers and typical city joints in a way that feels car-like for this class. After 5 km of patched city asphalt, my knees were fine and my feet weren't buzzing. Push it onto really broken surfaces or cobbles and, yes, you're reminded there's no actual suspension; the frame transmits the bigger hits, and you start picking your lines a bit more carefully.
Steering is calm, with a stable front end. At its top speed it feels composed rather than nervous, and the longer wheelbase and bigger wheels definitely help if your bike lane suddenly turns into a moon crater because the council ran out of money.
The KuKirin S1 Max does the opposite: smaller, solid honeycomb tyres, backed up by simple front and rear springs. On perfect asphalt, it's absolutely fine - firm but controlled. As soon as the surface degrades, you feel more of everything. The suspension takes the edge off the constant chatter, but it can't fully hide the fact that there's no air in those tyres. Ten kilometres of broken sidewalk on the KuKirin and you'll know how much your ankles enjoy your life choices.
Handling-wise, the lighter weight and narrower bars make it nibble and agile at low speeds - nice for threading through pedestrians or bike traffic. At its top speed, though, especially on rougher ground, the small wheels and lighter front end feel a lot busier. It's rideable and predictable, but you're paying more attention and relaxing less than on the Hiboy.
Comfort verdict: if your city surfaces are decent and you value stability and a "bigger scooter" feel, the Hiboy is clearly nicer to ride. If your trips are short and you value agility more than plushness, the KuKirin is acceptable - just don't expect miracles from solid tyres, suspension or not.
Performance
Both scooters sit in the sensible-commuter power band, but they deliver it quite differently.
The Hiboy S2 Max has a stronger motor and higher-voltage system. Off the line it feels willing and noticeably punchier than most rental-class machines. You twist your thumb, it responds without that lazy "come on, wake up" moment. Getting up to its cruising speed is brisk rather than brutal, which is exactly what you want in dense traffic: enough snap to beat the cars off the line and claim your space, not enough to scare a new rider.
On mild hills, the Hiboy just goes. On steeper ramps and with heavier riders you'll feel it slow, but it still pushes on without giving up completely. Compared to cheaper 36 V commuters, it feels more determined climbing - you don't have to start planning a walking section every time you see a bridge.
Braking on the Hiboy is handled by a front drum plus rear regen. The drum gives a predictable, mechanical bite, while the regen adds drag as you squeeze. Stopping distances feel reassuring for its speed, even in the wet, though the electronic brake can feel a bit grabby until you get used to it or tweak it in the app.
The KuKirin S1 Max lives a league down in power, and you feel it. Acceleration is gentler, and getting to its top speed takes a bit longer, but for flat city streets it's adequate. At the legal limits on smaller tyres, you probably don't want violent shove anyway. It's enough to keep up with bike traffic and not feel like a rolling chicane, but you won't be drag-racing anyone up an incline.
On hills, physics quickly remind you what you paid. Gentle inclines, overpasses and typical European bridges are fine. Steeper streets, especially with heavier riders, turn into "assist with a couple of kicks and be patient" territory. It will grind its way up, but don't expect dignity.
Braking is where the KuKirin shows its cost-cutting most obviously. You have front electronic braking and a rear foot brake on the fender. The regen at the front is mild and smooth, good for scrubbing a bit of speed, but in real emergency stops you're relying on your right leg and a piece of plastic. It works, and the stance shift actually encourages decent weight transfer, but it's never as confidence-inspiring as a proper hand-operated drum or disc. It's okay for the speeds and use case, but not what I'd call generous.
Battery & Range
Range is the main selling point of the Hiboy and the secret weapon of the KuKirin.
The Hiboy S2 Max packs a noticeably larger battery at a higher voltage. In the real world - mixed riding, city speeds, average-weight rider, a couple of hills and some headwind because nature hates commuters - you're looking at very solid distance on a single charge. Long one-way commutes plus a detour home are realistic without staring at the battery bars in panic. You can ride at its top mode most of the time and still have meaningful range.
As the charge drops, the Hiboy hangs onto its power reasonably well. You don't suddenly feel like you're on a rental scooter with dying batteries; the higher voltage helps keep things lively almost until the end. The trade-off, of course, is charging time: fill that bigger pack from empty and you're well into overnight-territory. Lunchtime top-ups won't do much unless your lunch breaks are heroic.
The KuKirin S1 Max runs a smaller, lower-voltage pack, but for its weight class the capacity is surprisingly generous. Realistically, if you hammer it in the highest mode at its full speed on flat ground, you can still commute both ways across an average city without needing to find an outlet. Ride more gently or mix modes and it stretches nicely, but this scooter is clearly designed around shorter hops and multi-modal trips, not huge cross-town epics.
Because the motor is weaker and the top speed lower, the energy use per kilometre is actually pretty decent. The downside is that when you hit hilly areas or throw a heavier rider on it, that efficiency advantage evaporates quickly - the motor has to work hard close to its limits. Charging is again an overnight thing; the slightly smaller battery doesn't charge much quicker in practice with the included slow charger.
On the range-versus-weight-versus-price triangle, the Hiboy gives you more range per charge; the KuKirin gives you enough range while staying lighter and much cheaper. Which matters more depends entirely on how many kilometres you actually ride in a typical day.
Portability & Practicality
This is the KuKirin's home turf - and where the Hiboy starts to show its bulk.
The KuKirin S1 Max is genuinely manageable. Around mid-teens in kg, folded down into a compact package, it's perfectly realistic to carry it up a couple of flights of stairs or through a train carriage without fantasising about moving to a ground-floor flat. The simple, fast folding mechanism is one of its best features: a quick movement, the stem locks to the rear, and you're walking with it in seconds. Under a desk, behind a door, in a tiny city flat - it just disappears.
Solid tyres mean you're also not wasting evenings wrestling with inner tubes or hunting for a friendly bike shop. For the sort of rider who doesn't own tyre levers and would like to keep it that way, this is a real, practical advantage.
The Hiboy S2 Max is what I'd call "semi-portable". You can absolutely lift it into a car boot, up a short stair run or onto a train, but you'll feel the extra kilos, and doing that every day up four floors will have you auditioning friends for "favourable scooter-carrying potential". Folded size is still commuter-friendly, but it's bulkier and heavier everywhere - something you feel as soon as you grab the stem.
The Hiboy does fight back with a more commuter-focused feature set: better app, electronic locking, cruise control that's actually pleasant to use on long straight paths, and a deck and stand that behave more like what you'd expect from a primary vehicle. But if you prioritise lifting and carrying over everything else, the KuKirin is clearly the more practical object.
Safety
Safety is a cocktail of tyres, brakes, lights and stability - and here the Hiboy quietly just does more of the basics right.
The Hiboy S2 Max benefits massively from its larger pneumatic tyres. Grip is better on wet surfaces, it tracks more securely through corners, and it handles road imperfections with fewer nasty surprises. At its top speed, the combination of tyre size, wheelbase and stem stiffness makes it feel stable and predictable. The dual braking - drum plus regen - gives decent stopping power even on damp mornings, and the rear light that flares under braking is actually visible enough to be useful in traffic. Side reflectors are a welcome touch for junction visibility.
The KuKirin S1 Max has adequate lighting for city speeds, and the IP rating is fine for occasional rain, but the 8-inch solid tyres are a safety compromise you always feel. They are less forgiving on slippery paint lines, potholes or scattered gravel, and the smaller diameter means more violent reactions to anything you fail to dodge. The braking setup, with no hand-operated mechanical brake, is acceptable at its limited speed but not generous. It's safe if ridden with margin and attention; it gives you less buffer when you or someone else makes a mistake.
If we're talking about sending a new rider into mixed traffic, I'd much rather they had the Hiboy under their feet.
Community Feedback
| Aspect | Hiboy S2 Max | KuKirin S1 Max |
|---|---|---|
| What riders love | Strong real-world range; noticeably better comfort than solid-tyre rivals; solid, "tank-like" feel; good hill performance for the price; app with useful tweaks; lighting that actually works in traffic. | Easy to carry and fold; totally puncture-proof tyres; very good value for money; decent real-world range for a light scooter; "grab and go" simplicity; acceptable suspension for a budget model. |
| What riders complain about | Heavier than they expected; still a bit harsh on really bad roads without suspension; regen brake can feel abrupt; long charging times; mixed experiences with customer support and occasional app quirks. | Harsh ride on rough surfaces; foot brake not everyone's favourite; app often called buggy or pointless; display hard to read in bright sun; weaker hill climbing for heavier riders; hinge may need occasional tightening. |
Price & Value
On sticker price alone, the KuKirin walks in with a smug grin: it's significantly cheaper, often sitting where many brands are still selling what I'd generously call "electric toys". For that kind of money you get a proper adult load rating, decent battery, suspension and a realistically useful top speed. Purely in terms of euros per basic mobility, it's a strong offer.
The Hiboy costs distinctly more, edging up into the territory where buyers start to expect something approaching "serious vehicle" status. To its credit, it does deliver noticeably better ride quality, performance and range than the KuKirin. You see and feel where the extra money went: battery, motor, tyres, frame. The question is whether you'll actually use that extra ability, or just pay for potential you never tap.
If your commute is short and light, the KuKirin gives you a lot of scooter per euro, with obvious compromises. If you're genuinely replacing daily car or public transport over longer distances, the Hiboy justifies its price much better - even if it still doesn't quite feel as polished as the marketing would like you to think.
Service & Parts Availability
Both brands sit firmly in the "online-first, budget-focused" camp, which means: don't expect a showroom down the road with a coffee machine and a loaner scooter.
Hiboy has a large global footprint and a huge user base. That translates into two things: plenty of spares circulating online, and a thriving ecosystem of YouTube tutorials and forum posts on how to fix whatever you break. Official support experiences are mixed - some riders receive quick parts under warranty, others report slow replies and some back-and-forth. It's workable if you're a bit handy and willing to DIY, less so if you expect a dealer network.
KuKirin / Kugoo also has strong European distribution, with warehouses in the EU and a lot of third-party sellers carrying parts. They've been around long enough that local repair shops often have seen their scooters before. Official support has a similar "depends who you talk to and on what day" reputation, but the sheer volume of units sold means community knowledge is abundant, and spares like tyres, controllers and stems are relatively easy to source.
Neither is a service dream, but neither is an obscure white-label disaster. If you're willing to occasionally wield a hex key, both are acceptable; if you want walk-in premium service, you're shopping in the wrong price bracket entirely.

Final Verdict - Which Should You Choose?
If you're genuinely commuting - think daily rides that push past ten kilometres one way, mixed traffic, dodgy surfaces and the odd hill - the Hiboy S2 Max is the more complete scooter. It rides better, feels more planted, stops harder and goes further. It has its rough edges, and it's not exactly featherweight, but it behaves more like a proper little vehicle than a collapsible gadget. For most single-scooter households that want one machine to do it all, this is the safer bet.
If your life is built around trains, lifts, small flats and short hops, the KuKirin S1 Max still makes a lot of sense. It's the one you actually bother to carry upstairs instead of locking outside "just this once". The ride is firmer, the brakes feel more basic, and the power is modest, but in return you get low purchase price, zero puncture anxiety and a scooter that rarely gets in your way when you're not riding it.
Boiled down: choose the Hiboy S2 Max if your scooter is replacing transport. Choose the KuKirin S1 Max if your scooter is complementing it. And if you expect champagne refinement from either at these prices, you might want to adjust your expectations before your first pothole.

Overall Winner Declaration
In the Numbers Freaks Corner, the HIBOY S2 Max scores 6 points against the KUGOO KuKirin S1 Max's 4. In the Author's Category Battle, the HIBOY S2 Max gets 31 ✅ versus 12 ✅ for KUGOO KuKirin S1 Max (with a few ties sprinkled in).
Totals: HIBOY S2 Max scores 37, KUGOO KuKirin S1 Max scores 16.
Based on the scoring, the HIBOY S2 Max is our overall winner. Between these two, the Hiboy S2 Max simply feels more like something you can rely on as a daily transport tool. It rides with more confidence, has the muscle and range to handle real-world commutes, and leaves you stepping off feeling like you rode a compact vehicle, not a folding compromise. The KuKirin S1 Max still has its charm: it's the scooter you actually grab when you're wrestling stairs, short trips and a tight budget. But when I think about which one I'd want under me every grim Monday morning for the next few years, it's the Hiboy that wins on the road, not just on the spec sheet.
That's our verdict when we try to stay objective – but hey, riding is mostly about emotions anyway, so pick the one that will make you look forward to your commute every single day.
