Fast Answer for Busy Riders ⚡ (TL;DR)
The INMOTION AIR PRO is the better all-round choice for most urban commuters: it's lighter, easier to live with, surprisingly quick, and delivers a very polished "grab-and-go" experience at a noticeably lower price. The NIU KQi3 MAX fights back with more torque, stronger brakes, and a bigger battery, making it a solid pick for heavier riders, longer daily distances, or very hilly cities.
If you mainly ride medium-length commutes on decent roads and need to carry your scooter occasionally, go AIR PRO. If you prioritise range, braking muscle and hill-climbing above all else - and don't mind extra weight and cost - the KQi3 MAX makes sense. Both are competent; only one feels like the sweet spot.
Read on for the full, no-nonsense comparison before you drop several hundred euros on the wrong kind of "freedom".
Electric scooters have grown up. We're long past the era of rattly toys and sketchy folding joints; today's mid-range commuters can genuinely replace buses, cars, or at least a lot of Uber rides. The INMOTION AIR PRO and NIU KQi3 MAX aim squarely at that space: serious machines for people who actually ride every day, not just on sunny Sundays.
I've spent a lot of time on both: dragging them up stairs, abusing them on broken bike lanes, and seeing how they cope when the weather decides to be "very European". On paper, NIU brings the bigger muscles and battery; Inmotion counters with lighter weight, cleaner design, and a very smart set of compromises.
Think of the AIR PRO as the agile, well-trained commuter who always arrives on time, and the KQi3 MAX as the gym bro with a bigger tank and heavier shoes. Both will get you there - but the experience is very different. Let's dive in.
Who Are These For, and Why Compare Them?
These two scooters live in the same broad price band where most serious commuters shop: not bargain-bin cheap, not "I could've bought a used car" expensive. They're both single-motor, rear-wheel-drive, road-focused machines with no suspension, aiming to be that one scooter you ride every day to work, the gym, and back.
The NIU KQi3 MAX positions itself as the long-range "grand tourer": big battery, strong brakes, big-name brand, and the kind of build that says, "I'm not afraid of 10.000 km." It's for riders who want a moped-like feel without the licence plate.
The INMOTION AIR PRO is more of a precision commuter tool: lighter, sleeker, with performance that punches out of its class. It's for people who actually need to carry their scooter sometimes, fit it under desks, and don't want their daily vehicle to feel like a gym kettlebell with a stem attached.
They're natural rivals because both promise "proper vehicle" capabilities in a compact form - and both could be overkill or not enough, depending on your life and your roads.
Design & Build Quality
Pick up both scooters and the design philosophies are obvious in the first three seconds.
The INMOTION AIR PRO feels like it was designed by engineers who hate clutter. The wiring is almost completely hidden inside the stem and frame, so you don't get the usual spaghetti of brake lines flapping in the wind or snagging on door handles. The finish is understated and businesslike, the deck rubber is neatly integrated, and nothing rattles. It's the kind of scooter you can park in a modern office without it screaming "gadget from a discount bin".
NIU's KQi3 MAX leans into its moped heritage. It feels chunkier, more substantial, with a wide U-shaped deck and a thick, very confidence-inspiring stem. The halo headlight is pure theatre in a good way, and the red accents on the calipers and cabling make it look sportier than most commuters. The overall impression is "miniature EV", not "big e-scooter". Fit and finish is very good - bolts line up, plastics feel dense, hinges are solid.
Where INMOTION wins me over is the coherence of the package. That hidden wiring, the low-slung deck with battery inside, the clean hinge - it all feels very deliberate. The NIU does feel more "overbuilt" and tank-like, which is great for rider confidence, but you pay for that solidity in kilos and bulk, and visually it's a little more busy than elegant.
In short: NIU feels like a rugged tool; the AIR PRO feels like well-executed industrial design that happens to be fast.
Ride Comfort & Handling
Neither scooter has a traditional suspension, so comfort comes down to tyres, geometry, and how kind (or cruel) your city's road department has been over the last decade.
The AIR PRO goes for a split tyre setup: air-filled at the front, solid at the rear. The front absorbs the small chatter; the rear, well, doesn't. On good tarmac and half-decent bike lanes, the ride is surprisingly smooth and quiet. Hit broken asphalt or paving joints, though, and you'll feel those hits through your ankles. After a few kilometres on cracked city paths, you learn to ride "active": knees bent, eyes scanning, shifting weight before bigger bumps. The upside is razor-sharp, predictable handling - the scooter feels light and eager to change direction.
The NIU KQi3 MAX uses big, wide, tubeless pneumatic tyres front and rear. Run them at sensible pressures and they soak up a surprising amount of nastiness. On typical city surfaces - light imperfections, concrete slabs, slightly rough tarmac - the NIU feels more planted and plush than the spec sheet suggests. Combine that with very wide handlebars and a long, stable deck, and you get a ride that feels car-like in its stability, especially at higher speeds.
On truly bad surfaces - cobblestones, large broken patches, deep cracks - both scooters remind you there's no suspension. The NIU's extra mass helps it plough through a bit more calmly, but it can also transmit bigger thumps because the frame is so stiff. The AIR PRO, being lighter and with that hard rear tyre, can get a bit "chattery" at the back, making you instinctively slow down.
Handling-wise: if you like a nimble, flickable scooter that threads through pedestrians and tight cycle paths, the AIR PRO is more fun. If you want a planted feel and straight-line confidence at speed, the NIU takes it. Your wrists will probably prefer the NIU on longer, rougher rides; your biceps will prefer the Inmotion when you have to carry the thing.
Performance
Both scooters are properly fast for their class, easily outpacing rental fleets and budget commuters. How they deliver that speed, though, is very different.
The AIR PRO feels like a very well-tuned commuter on a mission. That rear motor, with its generous peak output, gives a punchy launch without wheelspin, then pulls you up to its top speed with a satisfyingly eager surge. In the fastest mode it keeps pace with quick city cyclists and will happily sit at the limit of what feels comfortable on small wheels. The throttle is nicely linear; you can feather it through traffic without any nasty surprises.
The NIU KQi3 MAX, thanks to its higher-voltage system and stronger peak power, just has more shove everywhere. From the first metre, once you've done the required kick-start, it feels meatier - especially if you're a heavier rider or you live somewhere with vicious overpasses. Acceleration is less "wow, that's crazy" and more "this is what it should have been all along" - strong, controlled, and sustained even as speed climbs.
Top-speed sensation is interesting. On the AIR PRO, hitting its upper range feels thrilling because the chassis is light and lively. On the NIU, cruising near its maximum feels strangely relaxed, like the scooter has plenty in reserve even when it doesn't. The extra mass and wide bars tame the drama, which some riders will love and some might find a bit... sensible.
Braking is where the NIU clearly dominates. Twin mechanical discs plus strong, configurable regen means you can haul the scooter down from speed in very short distances, and it remains composed while doing it. The AIR PRO's combo of front drum and rear regen is much better than many budget setups - smooth, predictable, and low-maintenance - but when you really hammer both from high speed, you feel the difference. The NIU just anchors harder.
Hill climbing follows the same script: both will handle normal urban gradients respectably, but the NIU shrugs off steep ramps that make the AIR PRO work for it, especially with heavier riders. If your daily route includes long, rude hills, the NIU's extra torque is noticeably reassuring.
Battery & Range
On paper, the NIU brings a significantly bigger battery to the fight, and in the real world that advantage absolutely shows.
With the AIR PRO, think of it as a robust medium-range commuter. Treat it like a normal human - mix riding modes, don't baby it, accept that you'll accelerate hard away from lights because you're not made of stone - and you're looking at a comfortable urban loop in the mid-twenties of kilometres, a bit more if you're lighter or disciplined with speed. Most people will charge daily or every other day if they ride modest distances.
The NIU KQi3 MAX stretches that into genuine "multi-day" territory for many riders. Even fairly heavy riders hammering along in the sporty mode tend to see real-world distances well into the forties of kilometres on a single charge. Take it easy in flatter cities and you can extend that further. Range anxiety almost disappears unless you're doing long countryside stretches or have a brutal, hilly commute.
Efficiency-wise, the AIR PRO does reasonably well for its battery size, helped by its lower weight. The NIU uses more energy per kilometre, but its larger pack and regen make up for it. The experience difference is simple: with the AIR PRO you keep a subconscious eye on the battery icon if you're stretching your day; with the NIU you mostly don't think about it unless you forgot to plug in for two nights in a row.
Both scooters take roughly a working day or a night to recharge from flat. Neither offers truly "fast" charging, so plan on plugging them in like you would your phone - overnight is best.
Portability & Practicality
This is where the contrast is stark, and where many buyers regret not thinking it through.
The INMOTION AIR PRO sits right at that magic point where you can still reasonably carry it. It's not featherweight, but most adults can lug it up one or two flights of stairs without needing a break. The folded package is slim, with the clean stem and lack of external cables helping it slide into tight spaces - under desks, between seats on a train, in the corner of a café. The folding mechanism is quick and simple, and once latched at the rear it's easy to grab the stem and go.
The NIU KQi3 MAX is frankly in "I'd rather roll it than carry it" territory. You notice those extra kilos the moment you lift it, and the thick stem isn't the friendliest thing to grab if you have smaller hands. Carrying it up several floors daily is a workout plan, not a commuting strategy. Folded, it's compact in length but those gloriously wide handlebars mean it still occupies a lot of sideways space - fine in a car boot, less fine in a busy metro at rush hour.
Day-to-day practicality beyond weight? Both have decent water protection, with the Inmotion taking a clear lead on battery sealing. Both have good fenders that save your clothes in the wet. Both have apps for configuration and digital locking. The AIR PRO scores extra for its almost maintenance-free rear wheel (solid tyre) and drum brake, while the NIU needs the usual occasional disc brake tweaks and tyre pressure fussing, especially if you want the comfort sweet spot.
If your commute involves daily stairs or frequent multimodal juggling with trains and buses, the AIR PRO is a much friendlier companion. If your scooter mostly lives in a garage, hallway, or car boot and you rarely have to carry it far, the NIU's extra heft isn't a deal-breaker.
Safety
Both scooters take safety seriously, but they prioritise different things.
On the AIR PRO, the highlight is stability and weather resilience. The low-mounted battery gives it a nicely planted feel, reducing that twitchy, top-heavy sensation you get on some cheaper models at speed. The front drum plus rear regen braking is more capable than it sounds on paper: the electronic braking kicks in first to keep things smooth, and the drum handles the heavy lifting without locking suddenly. Add a genuinely bright headlight that actually lets you see the road, not just be seen, and you've got a commuter that doesn't feel nervous at night.
NIU's KQi3 MAX goes harder in classic "safety features": that halo headlight is one of the best integrated lighting solutions in the segment, and the triple-brake system is confidence in lever form. Two mechanical discs plus powerful regen mean you can brake late without white-knuckling it, and the very wide handlebars make emergency manoeuvres more stable. The tubeless, self-healing tyres are another big plus: they significantly reduce the likelihood of a dramatic flat and are forgiving over small debris you don't see.
In the rain, the AIR PRO's sealed drum and high battery water protection are big advantages; the rear solid tyre, however, doesn't offer as much wet grip as NIU's fully pneumatic setup. The NIU's overall chassis stability, big contact patch and braking power feel excellent in poor conditions, though its slightly lower water protection rating means you should be a bit more cautious about proper downpours and standing water.
Both are a world away from the sketchy single-brake, dim-light scooters of a few years ago. If maximum braking performance and visibility are your top priorities, the NIU has the edge. If you're equally worried about electrics failing in the wet, the AIR PRO feels like the more belt-and-braces choice.

Price & Value
This is where things get interesting. The NIU KQi3 MAX costs noticeably more. For that extra spend you get more motor grunt, a bigger battery, more sophisticated braking, self-healing tyres and a very solid chassis. If you're going to exploit those strengths regularly - long daily rides, heavy rider, big hills - the money isn't wasted.
The INMOTION AIR PRO, though, sits at a sweeter spot for a lot of real-world commuters. It delivers very similar top-speed behaviour, adequate range for typical city use, better portability, and solid build quality for a chunk less cash. You're not paying for features you don't necessarily need if your daily loop isn't epic.
Think of the NIU as the "buy once, cry once" option if you know you'll hammer it daily and squeeze every kilometre from that battery. The AIR PRO is the smarter buy if your rides are moderate, your budget is sensible, and you'd rather keep the extra euros for a good helmet and some rain gear.
Service & Parts Availability
Both brands are established players, which already puts them a step above anonymous white-label machines.
NIU has broad brand presence across Europe, with a dealer and service network thanks to their moped lines. That means parts availability for things like brakes, tyres and electronics is generally good, and many scooter or moped shops already know the brand. The flip side: sometimes you're dealing with automotive-style processes - great when it works smoothly, slightly bureaucratic when it doesn't.
INMOTION has a strong reputation in the electric unicycle and scooter community, with a decent network of distributors and parts channels. Their scooters are popular enough that consumables and even less common parts are reasonably easy to source from specialist PEV shops. Community documentation and third-party support are good too, because enthusiasts have been pulling them apart and putting them back together for years.
In practice, you're not taking a gamble with either. If I had to pick one slightly more DIY- and enthusiast-friendly, I'd lean Inmotion; if you want a more mainstream "walk into a big dealer and drop it off" vibe, NIU edges it.

Final Verdict - Which Should You Choose?
If you strip away the marketing and look at how these scooters actually live in the real world, the INMOTION AIR PRO comes out as the more universally sensible choice. It's fast enough to be fun, light enough to be genuinely portable, well-protected against the elements, and priced where you don't feel like you've overcommitted to a hobby that might just be "commuting". It nails that "Goldilocks" brief: not too big, not too small, just right for normal city life.
The NIU KQi3 MAX is not a bad scooter - far from it. It's a strong, capable machine that shines when you give it what it wants: longer distances, bigger hills, and a rider who values solid braking and a hefty feel. If you're heavier, have a brutal commute, or you simply want to ride further and harder without thinking about the battery, it's a compelling option.
But for most riders with typical urban commutes, occasional stairs, and a sane budget, the AIR PRO feels like the more balanced, more liveable, and frankly more satisfying package. It doesn't try to be everything; it just does the important things very, very well.

Totals: INMOTION AIR PRO scores 28, NIU KQi3 MAX scores 31.
Based on the scoring, the NIU KQi3 MAX is our overall winner. For me, the INMOTION AIR PRO is the scooter that feels most "right-sized" for how people actually live and ride: quick, light on its feet, sensibly priced, and engineered with the kind of restraint that comes from experience. The NIU KQi3 MAX is a very capable machine and absolutely the better choice if you truly need its extra muscle and endurance, but it asks you to accept more weight, more cost, and a slightly more serious character. If you want your daily commute to feel sharp, efficient and just a bit cheeky, the AIR PRO is the one that will have you looking forward to every ride. The NIU will get you there with authority - the INMOTION is more likely to make you grin while it does it.
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.
