Fast Answer for Busy Riders ⚡ (TL;DR)
The KingSong KS-N12 Pro edges out as the more rounded, commuter-friendly scooter: it rides more maturely, feels better engineered, and delivers a calmer, more confidence-inspiring experience for everyday use. The KuKirin G2 Ultra fights back with raw dual-motor punch and a flashy cockpit, but it feels more like a budget hot-rod than a polished transport tool.
Choose the KS-N12 Pro if you want a serious daily vehicle with strong range, refined power delivery, and a safety-first vibe. Pick the G2 Ultra if you prioritise brutal acceleration, off-road-capable tyres, and maximum "specs per euro", and you don't mind a bit of tinkering and compromise around refinement.
Both can be fun, but they deliver very different flavours of "fun" - keep reading to see which one matches your roads, your wallet, and your patience for maintenance.
There's a particular kind of rider who ends up shopping for scooters like the KuKirin G2 Ultra and KingSong KS-N12 Pro. You've already burnt through a tame commuter, discovered that hills exist, and realised that 25 km/h with no suspension is best described as "punishment", not "mobility". Now you want something serious - but not a 40 kg tank with a death wish.
On paper, these two look like natural rivals: similar real-world top speeds, serious batteries, full suspension and grown-up braking. In practice, they come at the problem from quite different angles. One is a boisterous dual-motor show-off that screams value, the other a more sober single-motor machine carrying years of KingSong battery and control-board know-how.
If you're torn between them, stick around. I've put real kilometres on both, and they each have moments of brilliance - and a few moments where you quietly wish the engineers had tried just a bit harder.
Who Are These For, and Why Compare Them?
Both scooters sit in that awkward-but-interesting middleweight class: too big and powerful to be "last-mile" gadgets, but not yet in the insane hyper-scooter league. They're aimed at riders who actually replace car trips, commute real distances, and see 30+ km/h as cruising speed, not a fantasy.
The KuKirin G2 Ultra targets the "maximum fireworks per euro" crowd. Dual motors, off-road-ish tyres, a huge sci-fi touchscreen - it's the scooter equivalent of a tuned hatchback with a big spoiler. Best for riders who want to feel power under their feet and don't mind a few rough edges for the sake of performance and price.
The KingSong KS-N12 Pro is more of a grown-up's choice. Single rear motor, higher system voltage, a more conservative frame and a focus on consistent power and comfort rather than headline-grabbing numbers. Think well-sorted daily driver instead of weekend toy.
They overlap in speed, range, weight and target rider weight, so they'll appear in the same search results and showroom floors. But ride them back to back, and you'll quickly realise they're tuned for different personalities.
Design & Build Quality
Pick up the G2 Ultra (or, more realistically, grunt it off the ground), and it immediately feels like a budget performance scooter. The dual-pole front end looks dramatic and does add stiffness, but the finishes - welds, plastics, small hardware - all whisper "value engineering". Not disastrous, just clearly built to hit a price, not win design awards.
The integrated touchscreen is the star. It looks futuristic, sits flush, and makes most bolt-on LCDs feel like they were ordered from the cheapest parts bin. But you can also sense where corners were trimmed around it: the tactile feel of switches, cable terminations, even the kickstand all feel adequate rather than confidence-inspiring.
The KS-N12 Pro, by contrast, gives off a more coherent, "engineered as a whole" impression. The aluminium frame feels denser, the paint finish more uniform, and cable routing is tighter and less chaotic. Nothing screams ultra-premium, but nothing screams "AliExpress special" either. The deck mat, hinges, and fasteners feel like they've actually survived some internal testing, not just CAD simulations.
The KingSong's dash is less of a spectacle than KuKirin's touchscreen, but functionally it's better: bright, legible, and easy to read quickly. It looks like a proper instrument cluster, not a gadget glued onto a toy. Overall, if build feel and quiet solidity matter to you more than visual theatrics, the N12 Pro has the upper hand.
Ride Comfort & Handling
Both scooters promise full suspension, but they interpret that promise differently once you're rolling over real roads rather than marketing copy.
The G2 Ultra's dual swingarm springs combined with chunky 10-inch tubeless tyres give it a noticeably cushy ride over rough city streets. Cobblestones, paving seams, and broken tarmac are muted to "mild annoyance" instead of "orthopaedic event". But the spring tuning is on the sportier side; lighter riders get a reasonably controlled feel, heavier riders start to bounce a bit, especially at speed over repetitive bumps. The off-road-ish tyre pattern also adds a faint vibration on smooth asphalt - not awful, but you're always aware the scooter is set up more for variety than pure tarmac comfort.
The KS-N12 Pro feels more sorted. Its dual spring suspension doesn't look wildly different on paper, but on the road it handles sharp edges and long-wave undulations with more composure. It doesn't pogo as much over repeated bumps, and the road-oriented pneumatic tyres are quieter and more planted on typical city surfaces. After a long stretch of bad bike paths, my knees and wrists were simply less grumpy on the KingSong.
Handling-wise, the G2 Ultra is surprisingly nimble for its weight. The wide bars and dual-stem stiffness let you flick it between gaps in traffic with confidence, though the knobbier tyres make high-speed lean angles feel a touch vague on wet tarmac. It loves playful carving but needs a bit of respect in tight corners at higher speeds.
The N12 Pro corners more predictably. The rear-motor layout, road tyres and slightly more conservative geometry make it feel like it tracks exactly where you point it, without those little mid-corner corrections you sometimes do subconsciously on cheaper frames. It's less "look at me, I'm shredding" and more "I'll get you there without drama" - which, on a Monday morning commute, is often what you actually want.
Performance
This is where the spec sheets would have you believe the G2 Ultra absolutely embarrasses the KS-N12 Pro. Two motors versus one, more nominal wattage, off-road vibes - surely game over?
Pull away hard on the G2 Ultra in dual-motor sport mode and, yes, it lunges like it's offended by the concept of standing still. If you're upgrading from a 350 W commuter, your first full-throttle launch will be accompanied by an involuntary noise and a quick mental inventory of your life choices. It's genuinely brisk off the line and on steep city hills it barely breaks a sweat.
But once you get used to the shove, you start noticing the throttle mapping. Despite the sine-wave controller, in the spicier modes the response is a little on/off - fun when you're showing off, slightly tiring in tight urban environments where you want fine control around pedestrians. It loves to be ridden aggressively; it's less talented at calm, low-speed manners.
The KS-N12 Pro feels more mature. It doesn't leap forward with quite the same fireworks, but it delivers a strong, sustained push that feels very "electric unicycle DNA": lots of torque, but smoothed out. From standstill to city speeds it's decisively quick, and the higher system voltage keeps that power feeling consistent as the battery drains. On hills it may not rocket as brutally as the KuKirin, yet it rarely feels strained - more like a confident climb than a sprint.
At the top end, both scooters reach velocities that make you start scanning the road surface with religious intensity. Here, chassis behaviour and stability matter more than the last few km/h. The G2 Ultra's dual stem helps, but the combination of aggressive power and more off-road-oriented tyres makes it feel a bit busier under your feet. The N12 Pro feels calmer and more planted at the same speeds; you're less occupied with micro-corrections and more able to simply ride.
Braking performance is another key part of the performance story. The KuKirin's dual mechanical discs have decent bite, especially after you tweak cable tension. They'll stop you, but require a bit of mechanical sympathy and occasional adjustment to stay sharp. The KingSong's hybrid drum front / disc rear setup with electronic ABS feels more predictable in all weather: the front drum is wonderfully boring (in a good way) and the E-ABS reduces lock-up drama on slick surfaces. For everyday chaos - wet manhole covers, painted crossings - the N12 Pro's brakes inspire more confidence.
Battery & Range
On paper, both packs are broadly similar in total capacity, and that's reflected in real-world riding. You're looking at commutes, not Sunday-only toys.
The G2 Ultra's battery gives you a decent cushion for enthusiastic city riding. Abuse the dual motors, sit near the higher end of the speed range, and factor in some hills and stops, and you're realistically in that mid-tens of kilometres bracket before you're nursing the last bars home. Ride gently in single-motor eco mode, and you can push noticeably further, but that rather misses the point of buying a dual-motor KuKirin.
The KS-N12 Pro squeezes range in a slightly more disciplined way. Thanks to the higher voltage system and more efficient tune, you can ride at "proper" city speeds and still see very comparable, often slightly better, real-world distance per charge. What stands out more is how consistent the power feels over that range: the KingSong doesn't turn into a sad, sluggish donkey once the battery drops below halfway. It keeps its composure longer than the KuKirin, which starts to feel a bit more lethargic as the battery empties, especially if you insist on dual-motor antics.
Charging is a story of degrees rather than revolutions. Both are overnight propositions: plug in after dinner, ride in the morning. The N12 Pro typically finishes a bit earlier thanks to its combination of pack size and charger, but we're talking hours, not dramatic differences. You won't pick between them based on charging alone, but if you're the type who regularly empties the pack and needs it full again by dawn, the KingSong's slightly quicker turnaround is a small but real perk.
Portability & Practicality
Let's be blunt: neither of these scooters is "portable" in the way marketing departments like to pretend. They are both heavy, and if you try to treat them like folding Brompton replacements, your back will file an official complaint.
The KuKirin G2 Ultra, hovering around the low-thirties in kilos, crosses that psychological line where you can lift it, but you'd really rather not. The folding mechanism itself is surprisingly slick: quick to operate, stem locks down neatly to the deck, and once folded it's actually not too awkward to roll around. Getting it into a car boot or up a short flight of stairs is doable, carrying it several floors on a daily basis is misery.
The KS-N12 Pro is marginally lighter, and you do feel that small difference when you dead-lift it. The folding latch is secure and simple, and the balance when carried is slightly better thought out than on the KuKirin. Still, this is not a "train and scooter" combo for the average person; it's more "elevator and scooter". For both models, if your life involves lots of stairs, choose again.
Day-to-day practicality is where differences emerge. The KuKirin's big touchscreen is glorious until it's raining or you're wearing thick gloves. Adjusting settings can become a little game of "poke and hope", and bright sun can wash the display out more than on the more traditional LCD of the KingSong. The G2 Ultra's off-road-ish tyres and IP rating make it reasonably happy with light trails and grubby side roads, but you'll still want to avoid biblical rain.
The N12 Pro counters with decent app integration, a more intuitive display, and little usability touches like a sturdy, if slightly short, kickstand and sensible charging port placement. The hybrid brake system's low maintenance needs also pay off practically: less time fiddling with tools, more time riding. In everyday, boring life - locking it up, unfolding, checking the dash, dealing with weather - the KingSong just feels easier to live with.
Safety
Both scooters take safety more seriously than your average rental toy, but again, the flavour differs.
The KuKirin G2 Ultra gives you dual mechanical discs with big rotors, a stiff dual-stem front, and a surprisingly comprehensive light package with turn signals and deck lighting. At night, you're not invisible, and the low-mounted headlight does a decent job of revealing surface imperfections. The tubeless tyres are a significant plus: punctures are rarer and usually more gradual, giving you time to react instead of sending you straight into panic-braking mode.
However, mechanical discs at this power/speed level do demand regular love. Cables stretch, pads wear, and if you ignore them, lever feel degrades faster than you'd expect. And while the dual-stem design minimises wobble, the scooter's eager throttle and grippy-but-not-race tyres mean you need to be on your game at higher speeds, especially in the wet.
The KS-N12 Pro feels like it was designed by people who lie awake at night thinking about failure modes. The front drum brake is almost boringly dependable - it works in the dry, it works in the wet, and it requires minimal fuss. The rear disc adds the bite you need for emergency stops, and the electronic ABS helps keep things controllable when you stomp the lever in less-than-ideal conditions. Add in strong, high-mounted headlights, effective brake lights, deck lighting and clear indicators, and you get a package that makes you feel conspicuous in traffic in the best possible way.
Both are stable enough at their real-world top speeds, but the KingSong's calmer chassis behaviour and tyre choice make it feel slightly safer when you're close to the limit. With the KuKirin, you're more aware that you're on a budget performance scooter doing impressive things. With the KingSong, you're more inclined to forget the hardware and just pay attention to the road - which is really the goal.

Price & Value
Here's where things get awkward for the KingSong and very comfortable for the KuKirin.
The G2 Ultra comes in at a substantially lower price and delivers dual motors, a sizeable battery, tubeless tyres and that big integrated touchscreen. In cold "specs per euro" terms, it's undeniably impressive. You are, however, paying less for a reason: refinement, component quality, and long-term polish simply aren't on the same level as more expensive mid-range brands. If you judge value as "how much speed and power I get for each euro", KuKirin is very hard to beat. If you judge value as "how little hassle I'll have over two or three years of commuting", the story is more nuanced.
The KS-N12 Pro sits much higher on the price ladder. You could buy a G2 Ultra and still have change for safety gear and a decent lock. What you get for that extra spend is not a radical leap in outright performance, but a lift in feel: better engineering, a more cohesive ride, more confidence in the electronics, and a scooter that behaves like a transport tool rather than a toy pretending to be one. Whether that's "worth it" depends on how you ride and how tolerant you are of small compromises.
If you're forensically counting euros and want maximum thrill per bank statement, the KuKirin looks the better deal. If you're planning to rack up serious weekday kilometres and care about the overall experience as much as the headline numbers, the KingSong justifies its premium more convincingly.
Service & Parts Availability
KuKirin (formerly Kugoo) has improved its European presence, with warehouses and some parts availability on this side of the world. There's also a lively ecosystem of third-party bits and community guides; you won't suffer alone if you need to swap brake calipers or silence the suspension. But official service can still feel a bit distant and hit-or-miss depending on where you live and which reseller you bought from. Expect to be at least somewhat hands-on.
KingSong, thanks to its long history in the electric unicycle space, tends to have a more established service network and better relationships with specialist dealers. Control boards, batteries and structural parts are more likely to be available through official channels, and you'll find more EU-based shops comfortable working on them. It's not automotive-level convenience, but it's a step up in maturity compared to many budget-performance brands.
If you're the type who happily changes pads, adjusts brakes and tightens bolts, the KuKirin ecosystem is fine. If you'd prefer to drop your scooter at a specialist and pay someone else to swear at seized bolts, the KingSong option will generally be less stressful.

Final Verdict - Which Should You Choose?
Both of these scooters live in that grey area between "sensible commuter" and "slightly unhinged hobby", and both manage to be usable daily vehicles with real performance. But they land on different sides of the maturity line.
The KuKirin G2 Ultra is the right choice if you're hunting for maximum excitement per euro. It pulls hard, demolishes hills, looks like a prop from a sci-fi film, and its tubeless tyres and dual-stem frame give it a reassuringly solid ride at speed. If you're happy to wrench a bit, keep an eye on brake adjustment, and accept some rough edges in exchange for serious shove and low purchase price, it delivers a lot of grin for the money.
The KingSong KS-N12 Pro suits riders who see their scooter as a day-in, day-out vehicle rather than a toy. It doesn't shout as loudly on the spec sheet, but on the road it feels more cohesive: smoother power, better-sorted suspension for urban surfaces, a brake system that's easier to trust in all conditions, and an overall construction that gives you more confidence long-term. If your commute is non-negotiable, your roads are imperfect, and you'd rather your scooter quietly get on with its job than constantly remind you it's a budget speed machine, the N12 Pro is the safer, calmer bet.
If I had to live with one of them as my only daily scooter, I'd lean to the KingSong for its balance and composure. The KuKirin is a fun, loud value play - enjoyable in bursts, but the KingSong is the one I'd more comfortably bet my weekday sanity on.
