Fast Answer for Busy Riders ⚡ (TL;DR)
If I had to pick one to live with every day, I'd take the Unagi Model One Classic for its superior build, cleaner design, lighter weight, and slick everyday usability - it simply feels more sorted and more premium in real life, despite its obvious range limitations. The Hiboy S2 fights back hard on price and features and makes sense if your budget is tight and you want "maximum scooter for minimum money", even if that means living with a harsher ride and more "budget" feel.
Choose the Unagi if you're a style-conscious commuter hopping on and off public transport, carrying your scooter a lot, and your daily distance is short. Choose the Hiboy S2 if you want an inexpensive, no-flats workhorse with app features and can tolerate a bit of rattling and roughness for the sake of savings.
Both can get you from A to B - but how they do it, and how you feel when you arrive, are very different stories. Keep reading if you want the full, road-tested truth before putting your money down.
Electric scooters used to be simple: you bought whatever didn't look like it would fold in half at the first pothole and hoped for the best. Today, even in the "commuter" bracket, you're choosing personalities as much as machines. Few pairings show that contrast better than the Unagi Model One Classic and the Hiboy S2.
On one side you have the Unagi: featherweight, obsessively styled, and engineered to slip under café tables and office desks without looking like you've dragged a toolbox through the lobby. It's the scooter for people who care as much about how it looks next to their laptop as how it climbs a hill.
On the other side sits the Hiboy S2: chunkier, more conventional, very budget-friendly, bristling with "spec sheet wins", and clearly built to a price. It's the one that says, "I'm here to work, not to be photographed," and then quietly reminds you how little you paid for it.
I've put serious kilometres on both. They solve similar problems in very different ways - and the trade-offs matter. Let's unpack where each one shines, where they stumble, and which actually fits your life.
Who Are These For, and Why Compare Them?
Both scooters live in the urban commuter world: pavement, bike paths, short to medium distances, lots of starts and stops, and plenty of folding, carrying, and shoving into awkward spaces. Neither is a countryside tourer or off-road toy. Think commuting, campus runs, and city errands - not weekend trail expeditions.
The Unagi Model One Classic positions itself as a premium last-mile tool: light, compact, beautifully finished, clearly aimed at people who also compare laptop colours and care what their bag strap does to their jacket. Its performance is "zippy city" rather than "street rocket", with range that suits shorter hops rather than cross-town epics.
The Hiboy S2 lives firmly in the budget commuter space. It stretches your euro as far as it can: decent speed, usable real-world range, app integration, rear suspension, and zero-maintenance tyres, all for less than the Unagi's paint job probably costs. It's the usual first scooter for people testing the waters, or a cheap daily beater for those who don't want to baby their ride.
They compete because if you want a compact, everyday scooter for city life, these two will appear on the same shortlists - one tempting you with polish and lightness, the other with price and "look how much you get". The overlap is real; the experiences aren't.
Design & Build Quality
Pick them up and you immediately feel they came from different planets.
Unagi Model One Classic is unapologetically design-driven: carbon fibre stem, magnesium bar, seamless integrated cockpit, internal cabling, automotive-style paint, silicon deck. It feels like consumer electronics that happens to move you. No visible spaghetti of wires, no rough welds, no random brackets. Tolerances are tight, there's a gratifying lack of rattles, and even the folding joint looks like it belongs in a design museum.
Hiboy S2 goes for a more utilitarian aluminium frame that borrows heavily from the familiar Xiaomi silhouette. It looks fine - purposeful, understated, slightly anonymous. Some external cabling, a conventional clamp-and-hook folding setup, visible hardware. It feels solid enough for the price, but next to the Unagi you start to notice the cost-cutting: more play in joints after some use, cheaper plastics on the throttle and levers, and a generally "mass produced" aura.
In the hands, the Unagi is almost jewellery - you notice the smoothness of the surfaces and the lack of sharp edges. The Hiboy is more "hardware store tool": robust, slightly rough around the edges, but you don't worry about scratching it because, frankly, it already looks like it expects abuse.
If you care deeply about aesthetic coherence and premium feel, the Unagi walks away with this one. The Hiboy feels like a good deal; the Unagi feels like a finished product.
Ride Comfort & Handling
Both scooters share one crucial ingredient: solid tyres. That means no flats... and also, inevitably, more vibration. How they deal with that is where they diverge.
The Unagi has no suspension at all. Just small honeycomb solid wheels bolted to a stiff frame. On fresh tarmac or good bike paths, it's lovely: precise, direct, almost skate-like. You feel connected to the surface in a very controlled way. But once the pavement turns patchy or you hit cobbles, the scooter stops whispering and starts shouting. After several kilometres of bad city surfaces, your feet and hands will know exactly how much your municipality has neglected road maintenance.
The Hiboy S2 tries to soften the blow with rear spring suspension. It doesn't magically turn those solid tyres into clouds, but it does take the sharp edge off bigger hits - curb cuts, expansion joints, small potholes. You still get a lot of high-frequency buzz through the bars on rough asphalt, but the rear doesn't punish your spine quite as enthusiastically as the Unagi's rigid chassis does. It's more forgiving over broken surfaces, though you're always aware there's solid rubber under you.
In tight city manoeuvres, both are nimble, with narrow decks and relatively quick steering. The Unagi's lower weight makes it feel more flickable and playful; weaving through pedestrians and bollards feels natural and light. The Hiboy is a bit more planted but also more "scooter-ish" - you feel the extra mass when changing direction rapidly.
If your city has mostly smooth bike lanes, the Unagi's direct, precise feel is a joy. If "smooth" is something you only experience inside cafés, the Hiboy's suspension gives it the comfort edge - even if it still isn't what I'd call plush.
Performance
Let's talk "how they go", rather than what the spec sheets boast.
The Unagi Model One Classic in dual-motor form has a pair of modestly rated hub motors that together give it a surprisingly eager character. From a standstill it steps off the line cleanly and confidently - not wild, but purposeful. For such a lightweight scooter, the way it keeps pulling up moderate hills is the real party trick; it doesn't surrender the moment the road tips up. It won't drag you up brutal gradients at high speed, but compared to most ultra-light commuters, it climbs with unusual determination.
Top speed is in the "sensible but fun" bracket - enough to keep up with bike traffic and feel brisk on a cycle path, especially given its small wheels and stiff chassis. At full tilt on rough surfaces, though, you're very aware of the lack of suspension and start to back off out of self-preservation rather than lack of motor.
The Hiboy S2 runs a single front hub motor. It's not shy - acceleration is decent, and in its sportier mode it gets up to its capped speed briskly enough for everyday commuting. You won't be drag-racing cars off the lights, but you won't be that awkward scooter stuck in a dawdling limbo either. On hills, it does what budget commuters always do: handles mild inclines fine, slows on steeper ones, and eventually gives you that "please lean forward and help me" feeling if you throw too much gradient and weight at it.
At full speed, the S2 feels reasonably composed in a straight line, helped by its slightly greater mass and rear suspension. The front-drive layout can spin a bit on loose or wet surfaces, so you learn to be measured with the throttle when conditions are sketchy.
Braking is a big philosophical difference. The Unagi relies mostly on electronic braking on both wheels, with a backup stomp-on-it rear fender brake. Once you're used to the lever feel, stopping is predictable, but you don't get the reassuring mechanical bite of a proper disc at your fingertips. The Hiboy pairs regenerative braking with a mechanical rear disc, both actuated from the lever. The result is more abrupt but also more confidence-inspiring when you really need to scrub speed quickly - especially on declines.
Overall: the Unagi feels more refined in power delivery and punches above its tiny weight on hills; the Hiboy feels more conventional and a bit more secure when you really need to stop in a hurry.
Battery & Range
This is where expectations need a serious reality check.
The Unagi Model One Classic carries a relatively small battery. In practice, for an average adult riding briskly, you're looking at short-hop city use, not half-day exploring. Think station-to-office and a detour to grab coffee, not roaming across the entire city twice. On full-power mode with hills in the mix, you can watch the battery bars slide down faster than you'd like, and the gauge itself isn't the most honest narrator - it tends to drop unevenly, so you learn to judge by distance and habit rather than the on-screen optimism.
The flip side of that small pack: it charges relatively quickly and weighs very little. Plug it in under your desk and it's easily topped up within a working half-day. For true "last-mile" usage, it's adequate; for anything longer, you're living by the charger.
The Hiboy S2 offers a noticeably larger real-world range envelope. No miracles - manufacturer claims are, as usual, based on a featherweight rider on flat ground in conservative mode - but in practical terms it stretches comfortably beyond the Unagi. For a typical city commute plus a few evening errands, you're less likely to be hunting for a socket every single day, especially if your route is mostly flat and you're disciplined with speed.
Its battery also charges in a workday-friendly window, and the brick is small enough to live in a backpack. You still want to be realistic: if your round trip is pushing well into the high-teens of kilometres and you ride full blast, you'll be near the limit.
In simple terms: range anxiety appears earlier on the Unagi. If your commute is modest and predictable, that's fine. If you want more headroom and fewer mental calculations, the Hiboy is the safer choice.
Portability & Practicality
Here the Unagi finally flexes the muscles it was actually designed to have.
The Unagi Model One Classic is genuinely light. Carrying it up stairs with one hand is very manageable for most adults, and the beautifully sculpted stem doubles as an ergonomic handle. The one-button folding system is as good as everyone says: press, fold, click. You can go from riding to walking through a station in one smooth, unembarrassing motion without performing a wrestling show at the bottom of the escalator.
Its folded footprint is small, and because there are no greasy chains and no grimy cables, you're quite happy to hold it close to your clothes or slide it next to someone's leg on a train without feeling antisocial. Under desks, in boots of tiny cars, even next to your chair in a café - it just... fits.
The Hiboy S2 is still portable, but we're entering the "you notice the weight" zone. Carrying it up a flight of stairs is fine; multiple flights become a light workout. The stem latch works, but when new it can be stubborn, and it doesn't have the same satisfying precision as the Unagi's mechanism. Folded, it's longer and a bit more awkward to manoeuvre in tight spaces, and you're more conscious of knocking things (or people) with the front wheel.
For multi-modal commuting - lots of transitions between riding, walking, and public transport - the Unagi clearly wins. For simple "home to office, into the lift, done" routines, the Hiboy is acceptable, but you won't be delighted every time you pick it up.
Safety
Safety comes down to three main aspects here: stopping, seeing/being seen, and staying upright on the surface you're riding on.
Stopping: The Hiboy S2's combination of regenerative and mechanical disc braking gives it stronger, more reassuring deceleration, especially in emergency situations. It can feel abrupt until you adapt, but when a car door swings open in front of you, "abrupt" is not a complaint. The Unagi's dual electronic braking is smooth and low-maintenance but lacks that mechanical bite. The rear fender brake is there as backup, but it's more "emergency parachute" than primary system.
Lighting: The Unagi has neat integrated front and rear LEDs that look great and are adequate for being seen in urban lighting, but they're minimalistic - very on-brand, less so on-"light the road ahead" at higher speeds in darkness. The Hiboy takes the opposite approach: bright headlight, reactive tail-light and, crucially, side/deck lighting that makes you far more visible from oblique angles. At night in busy traffic, that wider light footprint is a real safety asset.
Grip and stability: Both roll on small solid honeycomb tyres with limited compliance and similar diameter, so neither loves potholes or wet paint. The Hiboy's front-drive can slip if you're too enthusiastic on wet or dusty surfaces. The Unagi's tiny wheels and completely rigid chassis mean you really cannot switch off - a deep crack will get your full attention. On perfectly dry, clean tarmac at commuter speeds, both are stable enough; once things get rough or slick, rider skill and caution matter more than usual.
Overall, on the pure safety toolkit - brakes and lighting - the Hiboy comes out ahead. The Unagi relies heavily on its agility and the rider's anticipation rather than raw hardware.

Price & Value
This is where the spreadsheets come out... and where the two scooters live on different planets.
The Hiboy S2 is extraordinarily cheap for what it offers. For well under what many people spend on a smartphone, you get a full-size commuter scooter with usable range, decent speed, dual braking, rear suspension, app connectivity, and puncture-proof tyres. In the realm of getting maximum function per euro, the S2 is very hard to argue against. It's the sort of scooter you can recommend to a student without feeling guilty.
The Unagi Model One Classic sits at a premium price that, if judged purely by battery capacity and top speed, looks frankly unjustified. You can buy scooters with more range and more comfort for much less. But that comparison ignores the very reasons Unagi exists: ultra-low weight, premium materials, clever folding, and that refusal to look like industrial equipment. You're buying an object that feels engineered and finished to a higher standard, not just a vehicle.
Value, then, depends completely on which currency matters more to you: euros per kilometre, or quality and convenience per day of use. If cold efficiency is king, the Hiboy wins. If you care about how it feels to live with the scooter every single day, the Unagi makes a more nuanced argument - albeit an expensive one.
Service & Parts Availability
In the budget world, after-sales is often where dreams go to die. Both brands are better than the anonymous no-name imports, but in slightly different ways.
Hiboy has moved a lot of S2 units globally, and that scale shows. There's a big community, plenty of third-party videos on fixes and tweaks, and Hiboy is generally responsive in sending out replacement parts for common failures like fenders or throttle units. Official service centres aren't on every corner, but the scooter is simple enough that basic maintenance and part swaps are within reach of a mildly handy owner with a hex key.
Unagi runs a more "brand-forward" operation, with a reputation for decent customer service relative to most scooter outfits. They use better-quality cells and electronics than many generic competitors, and issues seem less frequent. That said, the scooter's integrated design and exotic materials make it less DIY-friendly. You're not going to casually replace its carbon stem in your kitchen.
In Europe, neither brand has the sort of brick-and-mortar support network you get with big mainstream e-bike brands, but between shipping parts and online guides, the Hiboy's simpler, more conventional layout is easier to keep on the road cheaply if you don't mind rolling up your sleeves. The Unagi aims to avoid problems rather than be easy to tinker with.

Final Verdict - Which Should You Choose?
Ultimately, these two scooters represent two very different answers to the same commuting question.
The Hiboy S2 is the pragmatic bargain. It gives you more range, stronger braking hardware, better lighting, app features, and a hint of suspension for a fraction of the Unagi's asking price. If you're on a tight budget, want a simple, no-flats workhorse, and can live with a buzzy ride and a more utilitarian feel, it absolutely does the job. You will not step off it thinking "premium", but you might well step off thinking "this cost me less than my phone and carries me every day".
The Unagi Model One Classic is the refined everyday object. It is lighter, better built, more thoughtfully integrated, far easier to fold and carry, and feels more like a finished consumer product than a cheap transport appliance. Yes, the range is short and comfort on bad roads is compromised, and that price tag is hard to swallow if you judge only by raw numbers. But if your rides are genuinely short, your surfaces mostly good, and you're constantly lifting, folding and storing your scooter, the Unagi delivers a more pleasant, less annoying daily experience.
So, which to buy? If money is tight or you want maximum utility per euro, take the Hiboy S2 with open eyes about its compromises. If you can afford to prioritise lightness, build quality, and sheer day-to-day niceness over specs on paper, the Unagi Model One Classic is the better companion - especially for style-conscious, multi-modal urban riders who live within its modest range envelope.

Lower "per-unit" figures are better for cost, weight and consumption; higher values are better for power density and charging speed. They don't tell you how nice a scooter feels - but they do show where each one is objectively thriftier or more power-dense.
