Fast Answer for Busy Riders ⚡ (TL;DR)
The KUKIRIN A1 edges out the IENYRID S1 as the more sensible overall choice: it's cheaper, still properly quick, and its tubeless tyres plus stout steel frame make it feel a bit more sorted as a daily urban bruiser. The IENYRID S1 fights back with plusher suspension, better ergonomics and nicer lighting, making it the comfier and more "feature-rich" option if you ride on rough mixed terrain and care about visibility.
Choose the KUKIRIN A1 if you want maximum power-per-euro, mostly ride on asphalt and don't mind doing the occasional brake tweak yourself. Go for the IENYRID S1 if comfort, off-road shortcuts, and a more refined cockpit matter more to you than saving that extra hundred euro.
Both are far from perfect, but each has a clear personality - read on to see which one matches yours before you commit your commute to it.
There's a particular class of scooter that makes you grin and frown at the same time. On paper, the numbers look suspiciously good for the price. On the street, they feel properly fast. And in the back of your mind, a little voice keeps asking: "What corners did they cut to get here?" The IENYRID S1 and KUKIRIN A1 both live in that slightly chaotic, high-value corner of the market.
I've ridden both long enough to drain batteries, curse at brake adjusters and discover which potholes each one really doesn't like. The IENYRID S1 is for the rider who wants a budget "mini off-roader" that can commute all week and play trail on the weekend. The KUKIRIN A1 is more of a muscle commuter - a slab of steel and watts aimed squarely at city riders who are tired of being overtaken by lycra.
They share similar power and weight, but they go about their job very differently. Under the surface gloss and spec-sheet bragging, one of them makes more long-term sense for most riders. Let's dig in.
Who Are These For, and Why Compare Them?
Both scooters sit in that dangerous "seriously quick, suspiciously affordable" bracket. They're way beyond rental-scooter performance, but still priced closer to entry-level commuters than to premium dual-motor monsters. Think enthusiasts on a budget, heavier riders who've outgrown 350 W toys, or suburban commuters with a decent daily distance who want something more exciting than a bicycle, but less insane than a 40 kg Dualtron.
The IENYRID S1 leans into the all-terrain commuter angle: big knobbly tyres, very generous suspension travel, wide deck, tall adjustable stem. It's pitched at people who hop between bike lanes, broken pavement, and gravel shortcuts.
The KUKIRIN A1 is more of a street fighter: tubeless road-friendly tyres, a stiff steel frame, and a design that favours asphalt speed and stability over plushness. It's for someone whose whole route is tarmac, speed bumps and the occasional tram track, and who wants to keep up with city traffic without spending four figures.
Same motor class, similar battery voltage, similar weight, similar top speed - they absolutely live in the same cage. That's why the comparison matters.
Design & Build Quality
In the hand, these two scooters feel like they come from different schools of thought.
The IENYRID S1 is very obviously "budget off-road inspired". Chunky aluminium frame, exposed suspension arms, off-road tread on the tyres, turn signals and side lights sprinkled on top. The adjustable stem is a rare treat at this price: tall riders in particular will appreciate not having to hunch. Up close, though, you notice a few tells of its price point - slightly inconsistent bolt finishing, a few rattly plastics, and that "you should really go over this with a hex key" vibe straight out of the box.
The KUKIRIN A1, in contrast, looks like someone took a city scooter and fed it protein shakes. The silver steel-tube frame feels brutally solid; welds are visible but respectable, and the whole thing has more of a "utility vehicle" impression than an off-road toy. The deck graphics are... subjective. Some will like the playful feathers, others will be planning how to replace the grip tape on day one. But panel fit and general solidity are a bit more confidence-inspiring than on the S1.
On pure materials and assembly feel, the A1 nudges ahead: steel tubing and fewer moving parts in the suspension department give it an impression of long-term toughness. The S1 counters with nicer cockpit ergonomics and more thoughtful rider-facing design, but you can sense where the money went - lots of features, slightly less finesse.
Ride Comfort & Handling
Comfort is where the IENYRID S1 earns its fans. That four-arm suspension setup, combined with big air-filled knobbly tyres, soaks up ugly city surfaces better than it has any right to at this price. Cobblestones, cracked pavements, tree-rooted cycle paths: the S1 just softens everything. After several kilometres of broken sidewalks, my knees still felt reasonably civilised, and the deck gives enough room to shuffle your stance to keep the blood flowing.
The KUKIRIN A1 also has both front and rear suspension, but it's a simpler, stiffer system. Think "takes the sting out" rather than "glides over". On typical European tarmac with the usual patches and seams, it's absolutely fine - even comfortable. Hit sharper edges or frequent broken slabs and you feel a lot more of the impact through your legs than on the S1. The wider bars on the A1 do help: at higher speeds the steering feels calmer and less twitchy than many budget scooters, including the IENYRID.
Handling-wise, the S1's off-road tyres and plush suspension give it great grip on loose stuff but a slightly vague feel on fast, clean asphalt, especially when you push the top end of its speed. It's not scary - just a bit floaty. The A1, with its tubeless road-oriented tyres and stiffer setup, feels more planted when you're hammering along a straight bike lane at full tilt. You do pay for that with more feedback in your joints on bad surfaces.
If your commute includes regular cobbles, gravel paths, or truly neglected pavements, the S1 is kinder to your body. If you mainly live on decent tarmac and care more about precision and stability at higher speed than about floating over every imperfection, the A1 has the edge.
Performance
On paper, both scooters are in the same power club. In the real world, they feel very similar in raw shove - but how they deliver it is slightly different.
The IENYRID S1 builds speed in a progressive but strong way. In its highest mode it pulls away from traffic lights with enough urge to surprise anyone stepping up from a rental scooter. There's a clear sense of torque from the rear, and it will happily sit at speeds where cycle-lane overtakings become a regular hobby. On hills, it doesn't disgrace itself: long moderate grades are no problem, steeper ones will slow it down but not kill it, even with a heavier rider.
The KUKIRIN A1, though, feels a bit more eager off the line. The throttle mapping is punchier; you get that immediate "shove in the back" as soon as you twist. It makes gap-shooting in city traffic easier, but it also means beginners really should start in the low mode until they learn some throttle discipline. On climbs, the A1 is at least as capable as the S1 and often feels stronger, especially if you're closer to the upper end of its weight limit.
Top speed sensation is similar: around the upper end of what feels sane on a standing scooter in city conditions. The S1's softer suspension can make high-speed bumps feel a bit wallowy, while the A1's stiffer setup and heavier steel chassis keep it more composed, if a little harsher.
Braking is a mixed bag on both. Dual mechanical discs plus electronic assist sound great, and when dialled in, both scooters stop convincingly from high speeds. In practice, you can feel the budget nature of the components: lever feel isn't as consistent as on higher-end gear, and both need periodic cable tweaks to keep braking sharp. The A1's weight distribution and stiffer chassis give it slightly more predictable emergency stops at speed, where the S1's soft front can dive a bit if you really grab the lever.
Battery & Range
Range claims for both scooters live in the usual marketing fairyland. In the real world, ridden like a real scooter (mixed modes, some full-throttle stretches, stop-start traffic), they land surprisingly close to each other.
The IENYRID S1 has the larger battery on paper, and you can feel the advantage if you ride in a slightly calmer style - cruising in the middle mode, not drag-racing cyclists at every light. You can realistically get a solid day's urban commuting without watching the battery indicator like a hawk. Start abusing mode three on every straight, and you'll still drain it fast enough to learn restraint.
The KUKIRIN A1 carries a bit less energy, but it's also not wildly inefficient. In my experience you can plan for similar real-world daily distances, just with slightly less buffer if you insist on living in the top mode. Near the end of the pack, both suffer from the familiar voltage sag: acceleration softens, and the last chunk of battery feels more like an eco mode whether you want it or not.
Charging is unremarkable on both: plug in after work or overnight, and they're ready by the time you need them again. The S1 does replenish a little faster relative to its capacity; the A1 takes a touch longer for a slightly smaller tank. Neither does anything clever like fast-charging or twin ports.
For most commuters with journeys under, say, a dozen kilometres each way, both will manage a full round trip comfortably. The S1 offers a bit more headroom if you add detours or weekend exploring; the A1 is adequate but less forgiving if you're heavy-handed with the throttle.
Portability & Practicality
Let's be blunt: neither of these is a "throw it over your shoulder" scooter. They're both in the kind of weight range where one flight of stairs is fine, three are annoying, and five become a gym session.
The IENYRID S1's folding mechanism is quick and reasonably solid. The adjustable stem can be dropped to shorten the folded package, which helps if you're stuffing it into a smaller boot. That said, the off-road tyres and suspension arms make it a bit more awkward to manoeuvre in tight indoor spaces, and the sheer bulk is very noticeable if you regularly have to lift it into car boots or onto train steps.
The KUKIRIN A1 folds in a cleaner, simpler way. The one-piece pole and hook-to-fender arrangement result in a more compact, tidy folded shape that's easier to grab and drag through doorways. Weight-wise it's essentially the same story as the S1: not outrageous, but definitely not a friendly daily carry for people without lifts.
In day-to-day living, both are happiest if you can roll them straight into a garage, hallway or lift without lifting much. The S1's extra lighting and onboard PIN lock are small but meaningful practicality wins in real urban use. The A1 answers with the physical key ignition, which is crude but effective against opportunistic theft.
If portability is a priority, you're looking in the wrong segment altogether. Between these two, the A1 is marginally easier to live with when it comes to folding and shoving into cars; the S1 compensates with better "user interface" details once you're actually riding around town.
Safety
Safety on scooters in this speed class is less about clever marketing features and more about basic competence: can it stop, can you see and be seen, and does it stay composed when things get messy?
The IENYRID S1 clearly tries hard on the visibility front. The high-mounted headlight is decent, but the real stars are the integrated turn signals and the side ambient lighting that traces a glow on the ground. In real traffic, that side visibility at junctions makes a noticeable difference. Many cars check sideways with a lazy glance; being lit up from the side is cheap insurance. Add a proper brake light and you're better equipped than a lot of scooters costing significantly more.
The KUKIRIN A1 counters with its own party trick: the side "cold light" logo and strong rear brake light. It doesn't have turn indicators, but the lateral glow does improve your silhouette in low light. The headlight is acceptable for city speeds, though it doesn't reach as far as I'd like when you actually use the full performance at night.
On stability, the A1's wider bars, heavy steel frame and tubeless 10-inch tyres give it a more reassuring stance at speed. It tracks straight, shrugs off small surface imperfections and feels less skittish when you're riding fast in mixed traffic. The S1 has the advantage of bigger off-road style pneumatic tyres and more travel, which help grip and control on loose surfaces, but the softer front can feel a touch nervous if you slam the brakes at the top of its speed range.
Both share the same headline brake setup and both will do their job if you keep the hardware adjusted - and that's the catch. Out of the box they're often not dialled perfectly, and they don't stay perfect without attention. If "maintenance" to you means "pumping tyres once a year", you'll be disappointed. For a rider who's comfortable with a hex key and a screwdriver, both can be kept safe. The A1 just feels a bit more predictable when you're right on the edge.

Price & Value
This is where things get awkward for the IENYRID S1. It's not expensive in absolute terms, but the KUKIRIN A1 undercuts it noticeably while offering similar real-world performance and a sturdier-feeling chassis.
The S1 does justify part of its higher price with that more complex suspension, larger battery, better lighting and more polished cockpit. If you actually use those advantages - night riding, bad paths, longer mixed-terrain commutes - then the extra outlay makes sense. But if your riding is mostly smooth city asphalt in daylight, you're paying for features you won't fully exploit.
The A1, meanwhile, channels most of its budget into motor, battery, and a robust frame, then skimps on things like hydraulic brakes, fancy displays or software tricks. You're essentially buying watts and metal, and on that narrow metric it's excellent value. It does feel like more scooter per euro for the typical urban rider, with the caveat that you must tolerate (or even enjoy) periodic tinkering.
Service & Parts Availability
Both brands sit in that "big in the budget scene, not exactly Apple Store" category.
IENYRID has a decent presence in enthusiast communities, but support experiences are mixed. Slow email responses, some language friction, and a sense that you're largely expected to handle simple issues yourself. The upside is that the S1 uses fairly standard components - generic mechanical callipers, common 48 V architecture - so third-party parts and DIY fixes are realistic even if official help is sluggish.
KuKirin, formerly Kugoo, has been around the European scene long enough to build warehouses and a more visible logistics footprint. Parts availability is generally better, and there's a larger user base producing guides, videos and mod tutorials. Official customer support still feels more like "budget online retailer" than "premium vehicle brand", but the ecosystem around the A1 is a bit richer and more mature, which matters when something inevitably wears out or you decide to upgrade components.
Neither offers premium after-sales experiences. Between the two, the KUKIRIN A1 benefits slightly from brand reach and parts access in Europe; the IENYRID S1 leans more on its tinker-friendly architecture and community ingenuity.

Final Verdict - Which Should You Choose?
Both scooters deliver far more speed and torque than their modest price tags suggest, but they take different routes to get there - and they cut slightly different corners. After living with both, the KUKIRIN A1 feels like the more rational recommendation for most riders: it's cheaper, just as quick in the real world, a little more stable at speed, and built around a frame and tyre setup that make solid sense for everyday asphalt commuting.
The IENYRID S1, however, is still an easy scooter to like. If your daily ride involves ugly surfaces, park paths, or you do a lot of night riding, its cushier suspension, generous lighting, and more comfortable deck and stem setup are genuinely worth paying extra for. It feels more like an "adventure commuter", while the A1 is very much an "urban muscle tool".
If you're a heavier or power-hungry rider with mostly paved routes and an eye on your wallet, the KUKIRIN A1 is the one I'd quietly nudge you towards. If you're willing to spend a bit more for comfort, visibility and some off-road flavour - and you don't mind doing the usual budget-scooter tightening and tweaking - the IENYRID S1 will still put a big grin on your face.
