Fast Answer for Busy Riders ⚡ (TL;DR)
The Hiboy S2 Max looks irresistible on paper with its bigger battery, higher top speed and lower price, but in daily use the Xiaomi 4 Pro is the more rounded, confidence-inspiring scooter and the overall winner here. The Xiaomi feels better screwed together, rides more predictably, and has superior ecosystem, support and resale - it's the one I'd trust as my primary commuter. The Hiboy S2 Max is worth choosing if your absolute priority is long range for the least amount of money and you can accept a rougher, more "budget brand" ownership experience. If you want something to just work, stay solid and be easy to live with, lean Xiaomi.
Stick around for the details - the spec sheet tells one story, the road tells another.
Modern mid-range commuters like the Xiaomi 4 Pro and the Hiboy S2 Max sit right in that dangerous sweet spot: fast enough to be fun, big enough to be useful, and just affordable enough to tempt you into a slightly impulsive purchase. Both promise "serious commuting" rather than toy-level transport, both roll on larger tyres, and both claim ranges that make rental scooters look like disposable lighters.
I've put real kilometres into both, on the same kind of diet they'll see in the wild: grimy city bike lanes, broken pavements, surprise potholes and the occasional "shortcut" that turns out to be gravel. One is the sensible all-rounder that quietly gets the job done; the other is the ambitious value champ that leans heavily on its spec sheet and battery size to win you over.
If you are torn between them, you are exactly the rider these two are fighting for. Let's dig in and see where each shines, where the marketing gloss wears off, and which one you'll actually be happy to live with every day.
Who Are These For, and Why Compare Them?
On paper, these two are natural rivals. Both live in the mid-range commuter class: one-motor, road-oriented scooters with enough power to handle real-world hills and enough battery to cover a decent commute without praying to the battery gods at every traffic light.
The Xiaomi 4 Pro is the "grown-up" evolution of the rental-scooter template: conservative speed, focus on refinement, safety and big-brand polish. It suits someone who thinks of a scooter as a tool: it must start every morning, feel predictable, and not demand a lot of attention.
The Hiboy S2 Max, in contrast, is a spec-driven value play. Bigger voltage, bigger battery, bigger claimed range and a higher top speed - all for significantly less money. It's aimed at riders who want "as much scooter as possible" per euro and are willing to trade some brand prestige and long-term polish for that.
Put simply: one is the safe commuter benchmark, the other is the long-range bargain hunter's darling. Same job, very different personalities.
Design & Build Quality
Park them side by side and you immediately see the philosophical split. The Xiaomi 4 Pro has that familiar minimalist, almost appliance-like look: matte dark frame, clean lines, cables mostly tucked away, and the feeling that the industrial designers actually spoke to the engineers once or twice. Welds are tidy, the stem feels like a single chunk of metal, and there's very little "budget" showing through.
The Hiboy S2 Max looks tougher and more utilitarian. The matte finish with orange accents gives it a slightly "industrial tool" vibe rather than consumer electronics chic. The frame is solid enough and there's no obvious flex in the stem or deck when you rock it, but you do notice more exposed cabling and slightly less finesse in the small details. It's not ugly, just more "functional Amazon commuter" than "polished tech product."
In the hands, the Xiaomi feels denser and more cohesive. The folding latch has a more premium, positive action and the deck rubber, grips and plastics look like they were chosen to last. With the Hiboy, nothing screams "about to fall apart", but levers, plastics and the kickstand all feel a touch more cost-optimised. You can tell where the budget went: into the battery and motor, not the last 10 % of refinement.
Ride Comfort & Handling
Neither scooter has proper mechanical suspension, so both rely heavily on their 10-inch pneumatic tyres to do the dirty work. But how they translate the road into your knees and wrists is not identical.
The Xiaomi 4 Pro, for a rigid frame, is impressively composed on decent tarmac. Those self-sealing tubeless tyres soak up the constant chatter of city asphalt very well, and the longer, wider deck lets you adopt a relaxed stance that naturally absorbs hits. The tall, wide bars give you plenty of leverage, so dodging potholes or weaving through cyclists feels calm rather than twitchy. On rougher cobbles or broken concrete, you are still very aware there are no shocks - after a few kilometres of that, your knees will file a complaint - but on normal city surfaces it feels planted and mature.
The Hiboy S2 Max also benefits hugely from its air tyres; compared to its solid-tyre siblings, it's night and day. On good asphalt it delivers that "buttery smooth" glide owners rave about. However, its overall ride feels a bit more upright and busy. The deck is fine, but not as generous; taller riders in particular feel more perched than integrated. On bumpy sections, the frame and cockpit transmit more vibration than the Xiaomi - not dramatically so, but enough that after a long stint on rougher pavement you remember why high-end scooters add actual suspension.
In corners, the Xiaomi's longer wheelbase and calm steering inspire a touch more confidence. The Hiboy is stable enough at its speeds, but it doesn't quite have that "rail-like" feel when leaning into sweeps. If your city is mostly good bike paths with the occasional scar, both are okay; if your daily route is a patchwork of ugly surfaces, the Xiaomi's ergonomics and tyre tuning give it a small but noticeable edge.
Performance
This is where the Hiboy tries to win the loudest. With a punchier motor and higher voltage, it accelerates more eagerly than the Xiaomi. From a standstill to its cruising speed, the S2 Max feels keen and energetic, particularly in its highest mode - enough to clear traffic lights decisively and keep up with the faster cyclists. It also walks away from the Xiaomi once both are at full tilt, pushing into that "just shy of moped-annoying" territory where you can comfortably flow with urban traffic, instead of feeling like the slow lane.
The Xiaomi 4 Pro plays a different game. Power delivery is smoother, more measured and very predictable. In its sportiest mode it gets off the line briskly enough, but never with that urgent shove the Hiboy delivers. And thanks to its legally capped top speed, you quickly sit at a sensible, regulation-friendly cruise. It feels calmer and more controlled, but if you like seeing the world blur just that bit more, you will definitely feel the leash.
Hill behaviour mirrors this split. On moderate inclines both scooters manage without drama, but the Hiboy's extra grunt and voltage help it hold speed better as the gradient kicks up, especially with heavier riders. The Xiaomi will still crest most inner-city hills without forcing you to kick along, but you do notice it settling into a more modest pace where the S2 Max keeps tugging a bit harder.
Braking is a closer fight. Xiaomi's combination of front electronic braking and a proper rear disc gives a very reassuring, progressive stop, especially once the pads have bedded in. Lever feel is good, and the front electronic brake blends in unobtrusively; you just slow in a clean, linear way. Hiboy's drum plus regen setup is low-maintenance and effective, but the electronic rear brake can feel grabby until you've learned to modulate it or tweaked it in the app. Once dialled, stopping distances are fine, but the Xiaomi feels more naturally intuitive from day one.
Battery & Range
Range is where the Hiboy S2 Max struts. Its battery pack is noticeably larger, and on real commutes that simply means you go further before hunting for a socket. Ridden briskly - full top-speed mode, plenty of starts and stops, some hills - it will still cover a genuinely long round trip that would leave many scooters sweating. Ride more moderately and you're into "several days of commuting between charges" territory for shorter city hops.
The Xiaomi 4 Pro is no slouch, but it sits a tier down in sheer endurance. Ridden enthusiastically it delivers a solid medium-length commute with some margin, but it doesn't have that "why is this thing still not empty?" feel the S2 Max sometimes gives. Be sensible with speed and mode and you can stretch it, but if you regularly plan long point-to-point rides with no charging at either end, Hiboy has the clearer buffer.
On the flip side, Xiaomi's battery management and overall efficiency feel more mature. Power doesn't drop off as sharply as the pack empties; the scooter still pulls reasonably late into the charge, and there's a sense the cells are being treated gently. Charging is a slower, overnight affair, whereas the Hiboy's slightly faster turn-around helps make up for the fact you are often filling a bigger "tank." For riders who plug in at home or work anyway, both are fine; for obsessive range junkies and gig-workers doing long shifts, the Hiboy's stamina is its main party trick.
Portability & Practicality
Neither of these is a featherweight, and both sit firmly in the "carryable, but not something you want to lug up five floors daily" zone. The Hiboy S2 Max is the heavier of the two, and you feel every extra kilo the moment you try to haul it up a staircase or into the back of a car with one hand. Short lifts are manageable; anything more and you start contemplating a gym membership or a ground-floor flat.
The Xiaomi 4 Pro isn't dramatically lighter but feels a bit more balanced when carried. Its revised folding latch higher up the stem is easier to operate, and when folded the package feels slightly more compact and well-secured. The stem locking into the rear mudguard is positive, and there's less floppiness than you often see in cheaper designs. The Hiboy's fold is quick and conventional, hooks onto the rear fender too, and works fine - it just feels more purely functional, with a little more play developing over time if you don't occasionally tweak the tension.
On the daily practicality front, Xiaomi's app integration, magnetic charging port and the generally more polished cockpit experience make it feel more like a modern gadget you slot into your life. Hiboy's app does the basics - lock, settings, cruise control - and cruise control is indeed pleasant on long straights, but it doesn't feel quite as slick or bulletproof on the connectivity side.
Safety
Both scooters tick the basic boxes: front and rear lights, reflectors, dual braking systems, decent tyres and sensible geometry. The Xiaomi, however, leans harder into safety as a design priority rather than a checklist item.
The 4 Pro's lighting is genuinely strong for a commuter: a bright, well-shaped headlight that lets you see and be seen, a clear rear light with brake activation, and on many versions, integrated turn signals at the bar ends. Being able to indicate without taking a hand off the bars is a small but meaningful upgrade when traffic is dense and road paint is slick. The self-sealing tyres are another under-appreciated safety layer: far fewer punctures, and therefore far fewer "I'm pushing a dead scooter along a busy road at night" situations.
The Hiboy S2 Max's lighting is decent and perfectly acceptable for city use. The high-mounted front light does illuminate the road ahead, and the brake-responsive tail light plus side reflectors give you a good silhouette. Tyres provide solid grip, and the higher top speed still feels stable rather than sketchy. But there are no indicators, and overall the safety package feels more "meets expectations" than "stands out."
Under emergency braking or on wet surfaces, I'd rather be on the Xiaomi: the braking balance and tyre tech combine into a more confidence-inspiring setup. The Hiboy will stop you, but it occasionally reminds you it's operating closer to its price bracket.

Price & Value
Purely on sticker price, the Hiboy S2 Max lands in a noticeably cheaper bracket than the Xiaomi 4 Pro. For that lower outlay you get more motor power on paper, a bigger battery, and a higher top speed. For riders staring at a budget ceiling, it's easy to see the appeal: you're checking off a lot of boxes for not a lot of money.
The Xiaomi asks for a healthy premium and then quietly spends it on things that don't impress on a product page: tighter tolerances, nicer materials, more conservative but robust engineering, and a brand ecosystem that's been around the block. Over a couple of seasons, that tends to show up in fewer weird creaks, easier access to spares, better resale value and less time arguing with support if something goes wrong.
If you judge value as "maximum spec per euro today", Hiboy looks like a steal. If you see value as "least hassle and best ownership experience over a few years", Xiaomi starts making more sense, even with its more modest go-fast credentials.
Service & Parts Availability
This is where big-brand gravity does its work. Xiaomi scooters are everywhere, which means parts are everywhere, tutorials are everywhere, and half the repair shops in any major European city have seen more Xiaomi stems and wheels than they care to remember. Need a brake disc, a tyre, a controller, or just a new dash cover? You can find it without detective work, often from multiple vendors.
Hiboy support exists, but it's more of a direct-to-consumer, online-only affair. Some riders report quick parts shipments under warranty, others tell stories of slow responses or generic troubleshooting scripts. Third-party parts and upgrades are available, but not with the same ubiquity or depth as the Xiaomi ecosystem. If you are handy and don't mind ordering bits from various online shops, you'll manage; if you want simple, local support, Xiaomi has the stronger network in Europe.

Final Verdict - Which Should You Choose?
Choosing between these two is really choosing between "spec sheet excitement" and "day-to-day serenity." The Hiboy S2 Max is the obvious pick if your budget is tight and your rides are long. It gives you very respectable speed, strong hill performance and generous range for significantly less money, and if you're comfortable living with a slightly rougher-around-the-edges product from a more value-oriented brand, you'll get a lot of kilometres out of it.
The Xiaomi 4 Pro, meanwhile, isn't trying to win spec wars. It aims to be the scooter that just calmly handles your commute for years: better-sorted brakes, more mature safety features, a stronger ecosystem, and a ride quality that, while far from luxury, feels more polished and predictable. If this is your main vehicle for getting to work, that quiet competence matters more than an extra handful of kilometres of range or a few extra km/h on a straight.
If I were advising a friend who wanted a reliable, low-stress commuter in a European city - someone who'd rather ride than fiddle - I'd nudge them toward the Xiaomi 4 Pro. And if another friend said, "I have a finite budget and I absolutely need the longest possible range, I'll live with some compromises," I'd say: get the Hiboy S2 Max, keep an eye on it, and don't skip your maintenance.

These metrics strip everything down to cold maths: how much you pay per unit of battery or speed, how much mass you haul per unit of performance, and how quickly energy moves in and out. Lower "per-something" figures mean you're getting more bang for your buck or your kilograms; higher power-to-speed and charging-speed numbers point to punchier performance and less time tethered to a socket. Efficiency (Wh/km) simply shows how gently each scooter sips from its battery in real-world use.
