Fast Answer for Busy Riders ⚡ (TL;DR)
The NIU KQi Air is the more complete scooter overall: lighter, better engineered, safer at speed, and with more usable real-world range, even if you pay noticeably more for the privilege. It feels like a refined, purpose-built urban tool rather than a spec-sheet stunt.
The HONEY WHALE E9 PRO, on the other hand, is for riders who want to spend as little as possible while still getting decent speed and basic comfort; it makes sense if your budget is tight and your expectations are realistic. Choose the NIU if you care about long-term quality, daily usability, and a calmer commute; choose the HONEY WHALE if you mainly need a cheap, zippy hop between home, bus and office.
If you want to know where each one pleasantly surprised me - and where they really didn't - keep reading.
Electric scooters have reached that fun point where brands are trying increasingly weird combinations of weight, power and price to stand out. On paper, the HONEY WHALE E9 PRO and the NIU KQi Air look like they're chasing the same rider: someone who wants a light, fast-ish commuter that won't destroy their back on the stairs.
In practice, they approach this goal from very different planets. The E9 PRO is the classic "budget hero with big numbers" - light, lively, attractively priced, and clearly tuned to impress the spec sheet shopper. The KQi Air is the carbon-fibre minimalist: less shouty, more engineered, and unapologetically premium.
If you're trying to decide whether to spend more on the polished NIU or gamble on the cheaper HONEY WHALE, this comparison will walk you through what actually matters once you've left the product page and hit real streets.
Who Are These For, and Why Compare Them?
Both scooters live in the lightweight commuter world: one-hand carry, quick-fold, meant for bike lanes and city streets rather than forest trails. They top out at roughly the same speed, carry similar rider weights, and are marketed squarely at multi-modal commuters who have to mix trains, offices and stairs into their day.
The overlap is obvious: both are positioned as "not a toy, not a tank". But where the HONEY WHALE tries to offer as much speed and punch as possible for a bargain price, the NIU KQi Air focuses on build quality, safety tech and premium materials. So the core question becomes: are you buying specs, or are you buying a tool you expect to live with daily for a few years?
Design & Build Quality
Pick up the HONEY WHALE E9 PRO and the first impression is: "Hey, that's nicely light for what it is." The aluminium frame is simple and fairly clean, and the V2 tweaks show someone has at least listened to rider complaints. It doesn't scream cheap at first touch - but it doesn't exactly whisper "precision engineering" either. Think decent budget commuter bike rather than high-end road machine.
The NIU KQi Air is... very obviously the opposite. The exposed carbon weave, the matte finish, the tidy cable routing - it looks and feels like something designed, not assembled. There's virtually no rattle, no flex, and the stem-lock clicks into place with the kind of confidence that makes you stop checking it every 200 metres. It's the sort of scooter you actually want to leave unfolded in your hallway because it doesn't look like a rental reject.
Ergonomically, the HONEY WHALE scores a nice point with its adjustable handlebars - handy if you're sharing it between different heights. But overall, the NIU feels like the more mature product: better tolerances, more consistent finishing, and a frame that feels like it will age gracefully rather than develop little noises as the kilometres pile on.
Ride Comfort & Handling
This is where their different philosophies show very clearly. The HONEY WHALE E9 PRO leans on its small spring suspension and conventional tyres to keep things tolerable. On decent asphalt and typical city bike paths it's fine, even pretty relaxed at moderate speeds. Once you hit rougher patches or dodgy paving, the combination of small wheels and budget-level damping becomes obvious. After a few kilometres of badly maintained sidewalk, your knees and wrists have strong opinions.
The NIU KQi Air goes suspension-free, which sounds like madness until you ride it. The larger, tubeless tyres and the carbon frame's natural damping take care of the constant small chatter surprisingly well. On good roads, it glides. On average roads, it's still the more composed scooter - wider bars, longer wheelbase feel, and that rigid, flex-free chassis give you much more confidence at full speed.
On really broken surfaces, though, reality bites: without springs, your legs become the suspension, and you'll be popping half-squats over every nasty patch. The HONEY WHALE's basic springs do help soften sharper hits a bit more, but the NIU counterpunches with better stability and grip. Overall, if your city has half-decent tarmac, the KQi Air is the more pleasant thing to ride; if your route is a festival of cracks and surprise potholes, the E9 PRO's small suspension advantage helps, but only up to a point.
Performance
Despite what the spec sheet suggests, the performance story isn't as simple as "higher motor rating wins". The HONEY WHALE's motor feels keen off the line in its higher modes; it has that slightly eager, budget-controller surge that beginners either love or find a bit abrupt. It's quick enough to nip away from traffic lights and doesn't completely surrender on moderate hills, but once you're closer to top speed, it feels like it's working hard rather than cruising.
The NIU KQi Air, with a nominally smaller motor, benefits massively from its lighter frame and more refined controller tuning. Acceleration feels smoother but no less eager, and it builds speed in a more linear, predictable way. There's less of that "on / off" sensation you sometimes get from cheaper throttles. On climbs, especially with an average-weight rider, the NIU hangs on better than you'd expect; it may not rocket uphill, but it doesn't bog down in that depressing slow-motion way some lightweight scooters do.
At max speed, the difference in confidence is clear. On the HONEY WHALE, you're very aware you're on a compact, budget commuter - you can do top speed, but you watch the road closely and keep both hands very honest. On the NIU, the wide bars, planted stance and better tyres make that same speed feel calmer and more controlled. Braking also favours the NIU: its front disc plus well-tuned regenerative rear gives you strong, settled stops, where the HONEY WHALE's rear disc plus motor brake setup is adequate but less confidence-inspiring in real emergency moments.
Battery & Range
Range claims in this industry are always optimistic, but even accounting for marketing fairy dust, the NIU KQi Air walks away with this one. In mixed riding - some full throttle, some coasting, a couple of hills - the KQi Air will comfortably cover a typical week of short commutes or a decent there-and-back daily trip without needing daily charging, unless you're really abusing the top speed constantly.
The HONEY WHALE E9 PRO's pack is more modest. Ride it gently in slower modes and you can get a decent day's urban use, but ride it as most people will - in the top mode, with lots of stop-and-go - and you're realistically planning around a shorter real-world range. For pure "last mile" hops or short commutes it's enough; for longer daily journeys, you start watching that battery indicator more often than you'd like.
Charging is pretty typical on both: roughly "overnight" versus "work-day" timelines. The NIU does edge ahead slightly with a shorter full charge despite its larger pack, which is a nice quality-of-life touch, but not a night-and-day difference. The key distinction is simply how far you can go before you need to plug in - and there the NIU is clearly the less anxious companion.
Portability & Practicality
Both scooters are light by modern standards, but one of them is clearly built to be carried a lot. The HONEY WHALE is impressive for its price: you can grab it in one hand, carry it up a flight or two of stairs and not hate your life, and its folded package is compact enough for under-desk duty or small car boots. The folding latch is a bit old-school but does the job, and once you've done it a few times, transitions are quick enough.
The NIU KQi Air takes that and turns it into a lifestyle. The lower weight might not sound dramatic on paper, but in your arm it absolutely is. Carrying it up three or four flights is "mildly annoying gym session" rather than "why did I buy this thing". It tucks under desks and into train spaces even more neatly thanks to its clean, narrow silhouette, and because it looks and feels premium, you're less worried about it being mistaken for a rental toy left in the hallway.
There is a minor practicality quirk on the NIU: the hook to latch the stem to the rear fender is a bit more fussy than the best folding designs out there, and you do have to bend down to engage it. The HONEY WHALE is a tad more grab-and-go in that respect. But over a week of actual commuting, the NIU's lower weight and tighter overall integration make it the one you're happier to live with if you fold and carry often.
Safety
Safety isn't just about brakes; it's about how comfortable you feel when something unexpected happens at speed. The HONEY WHALE ticks the basic boxes: dual braking (mechanical plus motor), lights front and rear, and a reasonably solid stem lock. You can ride it at its top speed if you're attentive and you know your route. At night, the headlight is adequate, and the flashing brake light is a nice touch.
The NIU KQi Air, though, clearly comes from a brand that builds full-size electric mopeds for a living. The lighting system - high-mounted headlight, halo running light, bright tail light, and those integrated bar-end indicators - actually makes you feel seen, not just technically illuminated. The front brake has much more bite, the regen rear brake is tuned sensibly, and the wide handlebars give you real leverage in emergency manoeuvres.
Add to that the NFC-based locking and the generally more planted chassis, and you end up with a scooter that not only stops better, but also helps you stay out of trouble in the first place. The HONEY WHALE isn't unsafe; the NIU is just clearly a class above in how seriously it treats the idea of you mixing with cars and inattentive pedestrians.

Price & Value
On sticker price alone, the HONEY WHALE E9 PRO is clearly the cheaper date. For riders whose budget ceiling is firm, that matters. You get serviceable performance, decent comfort and true portability for what many people would normally burn on a few months of public transport or fuel. If your ambitions are modest - short commutes, fair weather, smooth-ish roads - the numbers are tempting.
The NIU KQi Air asks you for a noticeably fatter wallet. And if you only look at watts and "claimed kilometres", you'll absolutely find heavier scooters that look better on paper for similar money. But you're not paying for raw grunt here; you're paying for engineering, materials, and long-term livability. The KQi Air feels like something you'll still be happy riding in two or three years, not just a clever bargain you tell your friends about for a month before the creaks start.
If you're brutally value-driven and can tolerate a bit more compromise in refinement and support, the HONEY WHALE can be justified. If you see your scooter as a primary mode of transport rather than a toy, the NIU's higher upfront cost is easier to defend over the life of the vehicle.
Service & Parts Availability
This is the unsexy part no one wants to think about until something squeaks, bends or stops turning. HONEY WHALE is still building its presence, and while there are pockets of decent local support, rider reports of slow responses and patchy parts availability aren't rare. For small stuff - tubes, basic maintenance - you'll be fine. For anything more involved, you might be Googling and improvising more than you'd like.
NIU, by contrast, has a proper footprint: dealers, service centres, and an established parts pipeline thanks to its much larger moped business. You're more likely to find someone who knows how to work on it, and parts won't feel like a treasure hunt. For risk-tolerant tinkerers, that might not matter; for commuters who just want their machine fixed quickly, it very much does.

Final Verdict - Which Should You Choose?
If you strip away the marketing, the NIU KQi Air is the better scooter for most riders who genuinely rely on their scooter for daily transport. It's lighter on your arm, calmer at full speed, better lit, better braked and offers significantly more usable range. It feels like a well-thought-out urban mobility device rather than a "good for the money" gadget.
The HONEY WHALE E9 PRO isn't without charm: it's cheap to buy, pleasantly lively, and genuinely portable. For short flat commutes, students hopping between campus buildings, or as a first step into e-scooters when you don't want to overspend, it absolutely has a place. Just go in knowing that you're trading away refinement, support depth and long-term polish for that attractive sticker price.
If budget is your hard limit and your rides are short and simple, the HONEY WHALE will do the job. If you can stretch your budget and you care about daily experience, the NIU KQi Air is the scooter you're far more likely to still be happy with after the honeymoon period is over.

Based on the scoring, the NIU KQi Air is our overall winner. For me, the NIU KQi Air is the scooter that actually feels like a trustworthy everyday companion rather than a clever compromise. It rides calmer, feels more solid under your feet, and has that rare quality where you stop thinking about the machine and just get on with your day. The HONEY WHALE E9 PRO has its moments - the eager motor, the friendly price - but once the novelty fades, its rougher edges are harder to ignore. If you can stretch your budget, the NIU simply delivers a more satisfying, grown-up experience every time you unfold 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.
