Fast Answer for Busy Riders ⚡ (TL;DR)
The Xiaomi 1S takes the overall win here: it's cheaper, more forgiving on real-world roads, and backed by a huge ecosystem of parts, tutorials and mods that make ownership pleasantly boring in the best possible way. The UNAGI Model One Voyager fights back with sharper acceleration, better hill performance and a genuinely premium design and folding experience, but asks a lot of money for not a lot of battery and a pretty punishing ride on rough surfaces.
Choose the Xiaomi 1S if you want a sensible, proven commuter that does the job with minimal drama and doesn't murder your knees on broken tarmac. Choose the UNAGI Voyager if you care deeply about looks, need serious portability with strong hill-climbing in a very light package, and your city has decent asphalt or bike lanes.
Both can get you to work; how much you enjoy the journey - and how much you pay for it - is where things really diverge. Stick around and we'll dig into how they behave in the wild, not just on spec sheets.
Electric scooters at this level are all about compromise: you never get everything, you just choose which compromises you're willing to live with. The UNAGI Model One Voyager and the Xiaomi 1S sit right at that awkward middle ground where price, performance and practicality collide.
I've put plenty of kilometres on both of these, from early-morning commutes on wet bike lanes to late-night "did I really choose this route of cobblestones?" moments. On paper, they're natural rivals: compact, relatively light, aimed at everyday city riders who don't want a 25 kg monster in their hallway. In practice, they feel very different.
If the UNAGI is the sharply dressed tech start-up guy with the latest phone, the Xiaomi 1S is the slightly scruffy colleague who always turns up on time, never breaks, and somehow costs half as much. Let's see which one you actually want to live with.
Who Are These For, and Why Compare Them?
Both scooters live in that "commuter first, fun second" category. They're compact, legally sensible in most European cities and aimed at people who mix public transport, short urban hops and the occasional longer detour when the sun comes out.
The UNAGI Model One Voyager clearly targets style-conscious urbanites who value low weight, clean design and don't mind paying a premium for it. It's effectively a designer last-mile device with a bit more bite than you'd expect from something this slim.
The Xiaomi 1S, meanwhile, is the mainstream template everyone else copied. It's for riders who just want something that works, fits under a desk, and doesn't require a Telegram group and a soldering iron to keep it going.
They compete because they answer the same fundamental question - "How do I get across town without a car?" - but they prioritise very different things: UNAGI leans into design and dual-motor punch, Xiaomi into price, simplicity and ecosystem.
Design & Build Quality
Pick up the UNAGI and the first thing that hits you is how much it feels like a consumer tech product, not a small vehicle. Carbon fibre stem, magnesium handlebar, fully integrated cabling - it's all very "if Apple did scooters". The surfaces are smooth, the colours tasteful, the folding button has that satisfying, engineered clunk when you press it. It's a scooter you can casually lean against a café wall without feeling you've lowered the tone.
The Xiaomi 1S is less glamorous, more "good industrial design". Aluminium frame, visible but tidy cable routing, matte finish with subtle red touches. You can tell it was designed for mass production and abuse. Nothing feels exotic, but nothing feels flimsy either. It's the kind of scooter you don't worry about locking to a bike rack in the rain.
In the hands, the UNAGI definitely feels more premium - no visible welds, no loose plastic, a wonderfully clean cockpit. The Xiaomi feels more utilitarian, but in a reassuring way: levers, bolts and parts look standard, replaceable and well understood. The UNAGI wins the showroom contest by a mile; the Xiaomi quietly looks like it will survive three winters of daily commuting and a few DIY repairs.
Ride Comfort & Handling
This is where reality rudely interrupts the design brochures.
The UNAGI rolls on small solid rubber wheels with a honeycomb structure. On silky new asphalt it's a joy - sharp steering, light on its feet, almost skate-like. The moment you stray onto old pavements, rough tarmac or cobblestones, it turns into a vibration delivery system. After a handful of kilometres on broken surfaces, you'll know exactly how your knees and wrists feel about the "no suspension, no air tyres" philosophy.
The Xiaomi 1S is also unsuspended, but the air-filled tyres make a world of difference. They take the edge off cracks, expansion joints and the usual city scars. You still feel the road - this is not a plush touring machine - but it's more of a constant low-level buzz than the sharp hits you get on the UNAGI. On cobbles or bricks, neither is comfortable, but the Xiaomi hurts less and for longer.
In terms of handling, the UNAGI feels more agile and almost hyper-responsive. Its narrow deck and low weight encourage an active stance and quick direction changes. Great in clean bike lanes, a bit nervy on loose surfaces because the solid tyres offer less give and less feedback. The Xiaomi is calmer, slightly slower to turn, but more confidence-inspiring, especially in the wet where the pneumatic tyres simply grip better.
Performance
Acceleration is the UNAGI's party trick. Dual motors in such a light chassis mean that when you thumb the throttle, it jumps forward eagerly. From traffic lights, you're out ahead of rental scooters and most entry-level commuters without even trying. On moderate hills, it just keeps hauling; where many scooters this light start to wheeze and slow to an undignified crawl, the Voyager keeps you moving at genuinely useful speeds.
The Xiaomi 1S, with its single front motor, feels more modest. On flat city streets it's absolutely fine - smoothly nudging you up to its regulation-friendly top speed without drama. It's not exciting, but it's not supposed to be. The power curve is gentle, predictable, beginner-friendly. On steeper inclines, however, the difference is stark: the Xiaomi will slow and occasionally beg for rider assistance with a few kicks if you're heavy or the hill is long.
Braking is another interesting contrast. UNAGI relies on dual electronic braking plus a stomp-on rear fender. The electronic system is smooth and progressive once you're used to it, but it lacks the "mechanical bite" feeling some riders want in an emergency. The Xiaomi combines a proper rear disc brake with front electronic regen. That lever feel - pads clamping on a disc - gives more confidence when you have to stop in a hurry, especially on questionable surfaces.
At their respective top speeds, the UNAGI feels a bit more taut and rigid, the Xiaomi a little more relaxed and rubber-footed. Neither is a high-speed missile, and that's probably for the best given their lack of suspension.
Battery & Range
Range is where the marketing teams like to dream and riders are forced back to earth.
The UNAGI's battery is small by modern standards, but reasonably energy-dense for its weight. In the real world, with a typical adult rider, using the scooter as intended (so: mostly full power, some hills, stop-and-go traffic), you're looking at a commute-length distance that's comfortable for many inner-city riders but not generous. Push it at its higher unlocked speed and that figure shrinks noticeably. The upside is that it recharges quite quickly; a long coffee and a laptop session can almost refill the tank.
The Xiaomi 1S claims more range on paper, but that figure is dreamt up in the usual gentle-pace, light-rider, flat-track scenario. In everyday city riding at full speed, you'll realistically land in the "there and back to work with a bit in reserve" zone. You get slightly more usable distance per charge than the UNAGI, but you wait longer at the wall socket. As a commuter tool, it feels less "on the edge" of its battery limits than the UNAGI, especially if your ride includes headwinds or rolling terrain.
In short: Xiaomi stretches your euros and watt-hours a bit further; UNAGI gives you a shorter leash but lets you top up that leash more quickly.
Portability & Practicality
Both scooters are genuinely portable compared to the increasingly obese mid-range market, but they do it with slightly different flavours.
The UNAGI is a delight to carry in short bursts. The one-click fold is arguably one of the nicest folding actions on any scooter: press, fold, done. The carbon stem's shape is surprisingly hand-friendly and the weight is squarely in the "carry it up two or three flights without cursing your life choices" bracket. Folded, it looks tidy and compact, the kind of thing you can slide next to your desk without it screaming for attention.
The Xiaomi 1S is marginally lighter on paper but feels a bit more basic in the hand. The latch-and-hook folding system is tried and tested: drop the stem, hook it to the rear mudguard, pick it up by the bars. Effective, fast enough, and every spare part for that mechanism is available for pocket change if it ever loosens up. It's a fuss-free tool rather than a miniature piece of industrial theatre.
In daily use, the difference is this: the UNAGI is nicer to fold and carry, the Xiaomi is easier to live with long-term thanks to its standard parts and huge repair ecosystem. If your commute involves lots of station stairs and elevator hopping, the nicer carry ergonomics of the UNAGI are noticeable. If you mostly just roll it in and park it, the Xiaomi's simple practicality is plenty.
Safety
Safety is a cocktail of brakes, tyres, lights and stability - and both scooters mix it a bit differently.
The Xiaomi 1S scores well on the fundamentals: mechanical disc plus front electronic braking, grippy air tyres, and lighting that's perfectly adequate for urban night riding. The headlight beam is sensible, the tail light bright and responsive under braking, and the added reflectors do their quiet work whenever car headlights hit you. On wet paint, manhole covers or greasy autumn leaves, those pneumatic tyres give you that vital margin before sliding.
The UNAGI's electronic brakes are smooth and low-maintenance, but they do require recalibrating your muscle memory. There's no "grab and you instantly feel pads on a disc" feedback, just a firming of the lever and the motors digging in to slow you. The backup fender brake is there for panic stops, but it's more of an insurance policy than a primary system. Lighting is nicely integrated and aesthetically superior - no wobbly plastic add-ons - but the front beam is more "be seen and fill in dark patches on lit streets" than "trust this as your sole light in pitch-black countryside".
Stability-wise, both are fine at their intended speeds, but again the tyres rule the day. On questionable surfaces, the Xiaomi gives more feedback and warning before grip goes away. The UNAGI's solid tyres mean grip is either there or suddenly... less there, especially in the wet. It's manageable, but you ride more cautiously on slick surfaces.

Price & Value
Here the Xiaomi 1S doesn't just edge ahead; it sprints away while the UNAGI looks on in its designer coat.
The UNAGI is priced firmly in "premium gadget" territory, yet its battery capacity and comfort don't exactly scream "best bang for buck". You're paying for the materials, the dual-motor setup, the aesthetics and the nice ownership touches. If those matter more to you than raw distance per euro, you may well find it worth it. But if you look purely at how far you get per charge and how much scooter you can buy elsewhere for similar money, it's not a value hero.
The Xiaomi 1S, by contrast, sits in that sweet spot where most people's budgets actually live. For the cost of a mid-range smartphone, you get a mature product with decent range, adequate performance and a repair ecosystem that keeps lifetime costs low. It's not cheap toy territory, but it's very accessible, and you don't feel like you've overpaid when you compare it to the rest of the market.
Service & Parts Availability
Xiaomi wins this one without breaking a sweat. Because the 1S is everywhere, everything for it is everywhere: tyres, tubes, discs, mudguards, stems, dashboard screens, chargers - you name it. Official parts, third-party upgrades, 3D-printed supports, custom firmware, endless YouTube tutorials... if something breaks, someone has already fixed it on camera.
UNAGI's support from the brand itself is generally praised: responsive customer service, a subscription model in some regions, and a sense that they do stand behind the product. But if you're the DIY type, sourcing specific parts is more of a brand-direct exercise than a "pop into your local electronics store or Amazon and get it tomorrow" situation. This scooter feels more like a sealed premium appliance than a tinker-friendly platform.

Final Verdict - Which Should You Choose?
If you stripped away the branding and price tags and just let people ride both on smooth city tarmac, a fair few would gravitate to the UNAGI. It feels sprightlier, looks cleaner, folds more elegantly and absolutely embarrasses the Xiaomi on hills. As an object, it's more satisfying: you can tell real effort went into making it feel slick and premium.
But scooters don't live in photo studios, they live in the battered bike lanes and patchy pavements of real cities. In that world, the Xiaomi 1S is simply easier to recommend to more people. It's kinder to your joints, vastly kinder to your wallet, easier to fix when something eventually rattles loose, and backed by a support ecosystem the UNAGI just can't match right now.
If your roads are smooth, your commute short, your hills nasty and you really appreciate thoughtful design - and you're willing to pay for that combination - the UNAGI Model One Voyager can absolutely make sense. For almost everyone else, especially budget-conscious riders or those facing mixed road quality, the Xiaomi 1S is the more rational, less stressful long-term partner.

| Average charging speed (W) | ✅ 90 W | ❌ 50 W |
These metrics strip away the emotions and look purely at efficiency and value. Price-per-Wh and price-per-km/h tell you how much "spec" you're getting for your money. Weight-based metrics show how much scooter you're carrying around for each unit of battery, speed or power. Efficiency (Wh/km) tells you how gently each scooter sips from its battery in real use. Power-to-speed and weight-to-power give a feel for performance density, while average charging speed reflects how fast you can put energy back into the pack. None of this says how they feel to ride - but it does explain why one stretches a euro, and the other stretches your grin.
