Fast Answer for Busy Riders ⚡ (TL;DR)
The NIU KQi1 Pro is the safer overall bet if you want a dependable, civilised commuter that feels like an actual vehicle rather than a disposable gadget. It wins on build quality, safety, refinement and long-term ownership, even if its performance is more "steady jog" than "sprint".
The HIBOY S2 SE fights back with more punch, a higher top speed and a very aggressive price, making it tempting for students and budget hunters who want maximum shove per euro and don't mind a harsher, more basic feel. Choose the Hiboy if performance and price trump comfort, polish and brand confidence for you.
If you care about feeling relaxed, safe and looked after a few years down the line, the NIU is the smarter choice. If you just want something cheap and lively to blast around on and you're willing to live with compromises, the Hiboy will do the job.
Now let's dive into the details and see where each scooter really shines-and where the marketing gloss starts to crack.
Urban commuters on a budget are spoiled for choice right now, and the NIU KQi1 Pro and HIBOY S2 SE are perfect examples of why it's getting harder, not easier, to pick a scooter. On paper they look eerily similar: compact city sleds, modest motors, sensible batteries and prices that sit well below the "oh dear, I've just bought a motorcycle" threshold.
On the street, though, they have very different personalities. The NIU KQi1 Pro feels like something designed by people who also build road-legal mopeds. The HIBOY S2 SE feels like something designed by people who read every forum complaint about flats and range-and then tried to fix them while keeping the bean counters happy.
In one sentence: the NIU is for the commuter who wants a calm, confidence-inspiring ride and doesn't care about bragging rights. The Hiboy is for the rider who wants a bit more shove and speed for as little cash as possible, and is willing to tolerate a few rough edges. Keep reading and we'll sort out which one fits your daily reality, not just your wishlist.
Who Are These For, and Why Compare Them?
Both scooters sit in the budget commuter category: think short to medium urban journeys, bike-lane speeds, a couple of flights of stairs and the occasional tram ride. Neither is built for off-road adventures or 30 km cross-city epics. These are "from the metro to the office" tools, not weekend toys.
The NIU KQi1 Pro leans towards the risk-averse rider: someone who values reliability, proper lighting, a good app and the reassuring sense that the manufacturer will still exist in a few years. You trade away a bit of speed and range, but you get a scooter that behaves predictably and feels reassuringly sensible.
The HIBOY S2 SE aims squarely at value hunters: more motor power, higher top speed, larger wheels and a price that undercuts most recognisable brand names. It's the classic "I want more scooter for less money" pitch, and that's exactly why these two deserve to be compared side-by-side.
Design & Build Quality
Pick up the NIU KQi1 Pro and it feels like a scaled-down moped: the frame is cleanly welded, the paint is even, the cables are tucked away, and the whole thing has that "designed as one product" vibe. The deck is pleasantly wide, the stem is thick without being clumsy, and the integrated halo headlight looks like it belongs on a small EV, not on a discount gadget.
The HIBOY S2 SE goes for a more industrial look. The steel frame gives it a solid heft, but also a slightly more utilitarian feel-less "designed object", more "functional tool". Cables are reasonably tidy, but you can tell where corners have been shaved compared to the NIU. The plastic bits, especially around the fenders and charging port, feel a touch cheaper in the hand.
In terms of finishing, the NIU feels the more premium of the two: better integration, more cohesive lines, and controls that feel a bit more refined. The Hiboy feels rugged but a bit rough around the edges, like a scooter that will take a beating but might develop the occasional rattle as the kilometres pile on.
Ride Comfort & Handling
Neither scooter has suspension, so your comfort is all about tyres, geometry and how much your knees are willing to help out.
The NIU rolls on smaller, air-filled tyres. They soak up the high-frequency buzz reasonably well, and with that wide deck and generous handlebar width, the riding stance is relaxed and stable. On smoother tarmac, it actually feels quite nice-direct and predictable, like a city bicycle. Over broken pavement and cobbles, you definitely feel the hits, but the grip stays reassuring and the steering is calm rather than twitchy.
The Hiboy's approach is... creative. Solid front tyre, air-filled rear, both larger in diameter. The bigger wheels help with stability and make it easier to roll over cracks and pothole edges, but the solid front tyre means your hands get the bad news first when you hit something sharp. The rear does a decent job of smoothing out the worst of it, especially since most of your weight is back there, but the front end still sends noticeable shocks into your wrists on rough surfaces.
Handling-wise, both are predictable, but they talk to you differently. The NIU feels planted and a bit more composed, especially at its legal-limit speed. The Hiboy feels livelier and a touch more nervous at higher pace-fun when the surface is smooth, less fun when the asphalt turns into a patchwork quilt.
Performance
Push off and thumb the throttle, and the NIU eases you into motion with a very gentle, well-controlled pull. The higher-voltage system gives it enough pep to keep up with bike-lane traffic, but it never feels like it's in a hurry. Top speed is set right around typical European limits; you reach it, sit there, and that's that. For commuting, it's adequate, but riders who've tried anything faster may feel a bit underwhelmed.
The HIBOY S2 SE, by contrast, actually feels eager. The front-wheel motor has a noticeable extra kick off the line, and the scooter is happy to creep past those usual shared-scooter speeds into territory that feels distinctly brisk on a small, rigid frame. Acceleration is still relatively smooth-not the kind that rips your arms off-but it's noticeably stronger than the NIU, and you feel that extra headroom when overtaking cyclists or punching away from traffic lights.
On hills, both have their limits. The NIU will handle typical city bridges and moderate inclines as long as you're not pushing the upper weight limit, but it doesn't like long, steep climbs and will slow down to a patient chug. The Hiboy's stronger motor does a little better, especially with lighter riders and a fresh battery, but it's still very much "urban incline" capable, not a hill-climbing monster. Heavy riders in hilly cities will find themselves kicking on both.
Braking on the NIU feels calm and controlled: the front drum combined with rear regen gives a smooth, progressive slowdown with very little setup fuss. On the Hiboy, the rear drum plus e-brake also deliver decent stopping power, but the weight transfer over that solid front tyre means hard braking can feel a bit sharper at the bars. Both can stop you safely; the NIU just does it with a bit more polish.
Battery & Range
Both scooters inhabit that "short commute comfort zone": not marathon machines, but enough juice for typical daily urban usage as long as you're realistic.
On the NIU, the battery is smaller on paper, and the claimed range is optimistic-like every scooter ever made. In real life, with an average-weight rider pushing at full legal speed, you're looking at a comfortable there-and-back for inner-city duties, but not much more. It holds its performance reasonably well until the battery gets low, which helps keep the ride consistent throughout your trip.
The HIBOY S2 SE boasts slightly higher claimed figures and a slightly larger pack, but its higher cruising speed and more powerful motor mean that advantage largely evaporates once you ride it the way people actually ride scooters: fast mode, throttle pinned more often than not. Real-world ranges of both scooters end up surprisingly similar-call it a typical daily commute plus some errands, not a touring machine.
Charging times are comparable: both are "overnight" or "during workday" chargers. Neither will impress a fast-charge enthusiast, but you're not going to be sitting next to one in a café, desperately nursing a battery from empty to full while your friends finish their second espresso either.
Portability & Practicality
Portability is where small differences really matter, especially if you're lugging the scooter up stairs or onto public transport every day.
The NIU is the lighter of the two and you feel it. It's no featherweight, but you can grab it in one hand, climb a flight or two of stairs and still have a bit of dignity left at the top. The folding mechanism is well thought out, snaps positively into place and, crucially, doesn't develop much wobble. Folded, it's compact enough to disappear under a desk without dominating the office.
The Hiboy's steel frame and slightly larger structure add noticeable heft. It's still portable in the grand scheme of scooters, but carrying it for any real distance is firmly in the "mini workout" category. The folding system itself is quick and straightforward, and locking the stem to the rear fender works fine, but you're working around that extra weight every time you move it. In a small flat or student room, both will fit, but the NIU is the one you're happier to move daily.
On the practicality front, both offer basic app integration, digital locking and decent dashboards. The NIU's app and overall ecosystem feel more polished and mature, with better-finished software and a stronger sense that it's part of a larger product family. The Hiboy's app is functional and offers useful tuning, but occasionally feels like it's trying to do a bit too much with slightly flaky Bluetooth manners.
Safety
Safety is where the NIU quietly pulls ahead. The braking system is simple, effective and low-maintenance; the front drum being enclosed means wet-weather braking stays consistent and there's less to bend or misalign. The overall chassis geometry, combined with those air tyres, gives a reassuring, predictable grip in corners and under hard braking, even if the ride is on the firmer side.
The halo headlight on the NIU is not just a design flourish: it actually throws usable light and makes you very visible to oncoming traffic. Combined with a proper rear light and reflectors, it feels like a scooter that has been designed with "please don't hit me" firmly in mind.
The Hiboy doesn't slack off here, to be fair. The lighting package is impressively comprehensive for the price: bright main light, side lighting, brake-responsive tail, the works. You're not invisible on this thing. The dual braking setup is also solid and inspires confidence... as long as you respect the slightly harsher feedback from that solid front tyre on rough surfaces. Wheel size helps it shrug off some road hazards, but the front-end harshness is a reminder that comfort and safety aren't entirely independent.
Water protection is a mixed story. Both claim splash resistance; both will survive wet roads and light rain. Neither should be your choice for monsoon commuting. The NIU's more premium feel and certification story give it a slight edge in the "I trust this with my battery and wiring" department.

Price & Value
On sticker price alone, the Hiboy looks like the obvious bargain. It undercuts the NIU by a meaningful margin while offering more motor power, larger wheels and extra speed. If your budget is tight and you're trying to squeeze the maximum amount of "scooter" out of every euro, it's hard to ignore.
But value isn't just a spec sheet exercise. The NIU comes with a stronger brand reputation, better build consistency, and a support network that behaves more like an established vehicle manufacturer than a hit-and-run import operation. Over a few years of commuting, that can easily offset the initial price difference-especially if you factor in potential repairs, downtime or simply the annoyance of a scooter that starts feeling tired early.
So: the Hiboy wins if you are buying purely on performance-per-euro today. The NIU wins if you think in terms of cost of ownership over several seasons of real, daily commuting.
Service & Parts Availability
NIU has the advantage of scale and presence. Their products are widely sold through proper dealers, many shops know how to work on them, and spare parts are relatively easy to source. Firmware updates, diagnostics and general ecosystem maturity give you the comforting sense that you're not on your own when something goes wrong.
Hiboy has also grown a solid footprint, especially online, and they do a better job than most budget brands at providing replacement parts and at least functional support. But you're more likely to be dealing with shipping parts and DIY repairs rather than dropping it at a local service centre. For the mechanically comfortable, that's acceptable. For those who just want a scooter that "someone else" can sort out, the NIU is the safer choice.

Final Verdict - Which Should You Choose?
If your scooter is going to be a daily companion rather than an occasional toy, the NIU KQi1 Pro is the more reassuring choice. It feels more like a grown-up transport tool: better integrated, calmer to ride, and backed by a brand and ecosystem that clearly understand urban mobility as something more serious than a weekend hobby.
Pick the NIU if your commute is short to medium, mostly on reasonable roads, and you value peace of mind over pace. It's ideal if you're new to e-scooters, if you want something you can hand to a family member without sweating about safety, or if you simply want a scooter that fades into the background and quietly does its job.
The HIBOY S2 SE earns its place for riders who are more price-sensitive and a bit more performance-hungry. If the budget is tight, the roads are mostly smooth, and you like the idea of squeezing every last bit of speed and power out of a limited spend, it makes a compelling case. Just go in with open eyes: you're trading away some refinement, comfort and long-term reassurance to get there.
In the end, both will carry you across town. The NIU is the one that's more likely to feel like a trustworthy little vehicle years from now. The Hiboy is the one that will make you smile at how much speed you got for the money-at least until the reality of daily bumps and bangs starts to show.
