Micro Merlin II vs KuKirin HX - Two Lightweight Commuters, One Clear Winner (But With a Twist)

Fast Answer for Busy Riders ⚡ (TL;DR)

If you want the smartest balance of ride comfort, safety and everyday usability for urban commuting, the KuKirin HX walks away as the overall winner - mainly because it delivers a more forgiving ride, better brakes and drastically better value, all while staying just as light.

The Micro Merlin II still makes sense if you absolutely prioritise premium finish, suspension in a very light package, and love the idea of Swiss engineering and long-term parts support - and you're willing to pay handsomely for that badge and a bit more comfort over rougher patches.

Budget-conscious city riders and first-time owners should look closely at the KuKirin HX; multimodal commuters with a fat wallet and a soft spot for "proper" European brands might still lean Merlin.

Stick around and we'll go deep into how both behave in the real world - including the bits the brochures gloss over.

Electric scooters in the 13 kg class all promise the same fairy tale: "I'm light, I'm practical, I'm comfy, and I'll make your commute effortless." After a few hundred kilometres on each of these two, I can confirm: reality is, as usual, more nuanced.

The Micro Merlin II comes from a heritage brand and sells itself as the refined, spring-loaded Swiss commuter: light, carefully engineered, suspension at both ends, and priced like someone has to pay for all that precision.

The KuKirin HX is the street-smart cousin: same featherweight class, bigger motor, air tyres, removable battery and a price tag that looks like a misprint next to the Merlin's.

If you're choosing between them, you're really choosing what you value more: polish and pedigree, or brutal value and practicality. Let's dissect them properly.

Who Are These For, and Why Compare Them?

Both scooters live in that sweet spot where you can still lift them with one arm without needing a chiropractor afterwards. They weigh about the same, sit firmly in the "urban commuter" category, and top out at legal-ish city speeds.

The Merlin II targets the multimodal commuter who wants something that feels more like a refined tool than a gadget - you know, the kind of rider who folds their scooter on the platform, then slides it under a train seat with the same satisfaction as closing a good briefcase.

The KuKirin HX aims at riders who live in flats, student housing or shared spaces and care less about brand prestige and more about not dragging a dirty scooter through the living room. The removable battery and lower price scream real-world pragmatism.

They compete because they promise the same core thing - light weight, legal top speed, compact folding - but go about it with very different priorities and price tags.

Design & Build Quality

Pick up the Merlin II and the first impressions are very... Micro. Clean lines, matte finishes, neatly integrated lights, hardly any visible bolts. The telescopic stem glides up and down with that slightly smug "Swiss appliance" feel. Nothing creaks, nothing flaps, nothing feels like it came off a supermarket special.

The folding handlebars and "kick-fold" stem are clever, if a bit too clever for their own good. The foot-actuated latch can be fiddly with chunky shoes, and it takes a couple of days of living with it before the movement becomes muscle memory. Once folded, though, the package is impressively slim and well locked together.

On the KuKirin HX, the design is more functional and less precious. The thick stem housing the battery gives it a slightly industrial look - it's not pretty, but it does look purposeful. The deck is slim and simple; the latch at the base of the stem is oversized and reassuringly clunky in a good way. Cabling is decently hidden for this price class, though you do notice you're not dealing with a high-end European brand the moment you start looking closely at finishing details.

In the hands, the Merlin feels more solid and rattle-free out of the box; the HX feels sturdy enough but you're more aware that stem bolts and fenders may need occasional tightening if you don't want to inherit a future wobble.

Verdict: The Merlin II wins on perceived quality and refinement. The KuKirin HX feels robust, but the Micro's fit and finish are clearly a notch up - as they should be at several times the price.

Ride Comfort & Handling

Comfort is where these two take very different routes.

The Merlin II tackles rough tarmac with dual suspension wrapped around small solid wheels. On typical city asphalt and mild cobblestones, that system actually works surprisingly well. The ride has a "springy" character: you feel the road texture, but the sharp edges are taken off. After a few kilometres over broken European pavements, your knees and wrists are still on speaking terms - which is more than you can say for many solid-tyre lightweights.

However, the combination of tiny solid wheels and suspension has its limits. Hit deep potholes or broken curbs and you'll still feel - and hear - it. The Merlin stays composed, but it never lets you forget that you're on relatively small rubber contacting the road.

The KuKirin HX goes the opposite way: virtually no suspension, but larger pneumatic tyres. On everyday city surfaces, those air-filled tyres do an excellent job soaking up smaller chatter and buzz. At the same speeds on similar routes, the HX actually feels more "planted" underfoot, with less of that trampoline sensation you sometimes get from light scooters with eager springs.

Handling is different, too. The Merlin, with its lower battery placement and longish wheelbase, has a calm, predictable feel. The adjustable stem height lets you dial in your posture, which makes a noticeable difference on longer rides. The HX, with its battery high in the stem, initially feels a bit top-heavy. Turning at low speeds can feel slightly heavier until you adapt, then it becomes second nature and you appreciate the stable, confident front end at speed.

Verdict: For pure comfort over rougher mixed surfaces, it's closer than you'd think - but the HX's pneumatic tyres give it the edge in day-to-day plushness, especially for longer rides. The Merlin strikes back with ergonomics and adjustable bars. If your city has a lot of cracked pavements and expansion joints, I'd lean HX; if you're often on smooth-ish surfaces and value posture, the Merlin holds its own.

Performance

Neither of these is a rocket ship - and that's entirely the point. They're built for city speeds, not drag strips.

The Merlin II runs a modest front hub motor that's tuned more for politeness than punch. Acceleration is smooth and progressive, almost conservative in its initial response. From standstill to top speed, it feels controlled and easy to dose with the thumb throttle. In dense traffic and shared paths, that kind of predictability is exactly what you want.

On hills, though, the Merlin's power ceiling shows. On typical urban inclines and bridges, it copes fine, but throw a longer or steeper ramp at it and you'll feel it labouring. You won't be walking, but don't expect to sail past cyclists on climbs, especially if you're on the heavier side or carrying a backpack.

The KuKirin HX has a slightly beefier front motor, and you do feel it. Acceleration off the line has noticeably more urgency, particularly in its higher mode. It still avoids the "jerk then pray" behaviour of some cheap controllers, but the HX is clearly the friskier of the two. Keeping up with bike traffic is easier, and small hills are taken with more confidence.

Push it onto sustained, steeper grades and the HX also eventually runs out of enthusiasm, especially if you're nearer its upper load capacity - but compared back-to-back, it handles climbs with a bit more dignity than the Merlin.

Braking performance is another important piece of this performance puzzle. The Merlin relies on a combination of motor regen, a drum brake and the classic stomp-on-the-fender option. It'll stop you, but the drum needs a firm hand, and emergency stops require a bit of commitment on the lever.

The HX pairs electronic front braking with a proper rear disc. Modulation is better, and "I need to stop now" situations feel more reassuring on the KuKirin - provided your brakes are adjusted correctly.

Verdict: The HX is clearly the more eager scooter in terms of acceleration and hill climbing, and its braking hardware inspires more confidence. The Merlin feels composed but a little under-motivated when the road tilts upward.

Battery & Range

On paper, the numbers don't look dramatically different. In practice, how the energy is used - and replaced - is where they diverge.

The Merlin II hides a compact battery in the chassis and promises a best-case range long enough for most city commuters if you ride conservatively. In real-world "ride it like a normal human" conditions - full speed where possible, stop-and-go traffic, some hills - you're realistically looking at something in the low-to-mid-twenties of kilometres before you're thinking about a charger. That's enough for most urban round trips, but not exactly touring material.

The upside is that the Merlin recharges quickly. Plug it in under a desk and you can go from nearly empty to full during a normal half-day in the office. The regen braking helps a little, but not enough to pretend it's a game-changer.

The KuKirin HX is more honest commuter than marathon runner. Its single battery will usually get you roughly the same ballpark of real-world range, perhaps a touch less if you're heavy-handed with the throttle. Where it absolutely outplays the Merlin is flexibility: the removable pack. Being able to slide the battery out like a giant power bank and swap in another completely changes the ownership experience.

Carry a spare in a backpack and suddenly your "modest" range doubles without adding any weight to the scooter itself. When the battery inevitably degrades after a couple of years, you replace the pack, not the whole vehicle. Charging is also straightforward and reasonably quick, and you can charge the battery in your flat while the scooter sleeps in a shed or stairwell.

Verdict: One battery vs one battery, both are serviceable, not spectacular. But the KuKirin's swappable pack and lower replacement cost make it the much more flexible and future-proof option for anyone who actually relies on their scooter daily.

Portability & Practicality

On the scales, it's essentially a draw: both sit around the same weight. The differences show up once you start living with them.

The Merlin II feels daintier in the hand thanks to its narrower stem and very compact folded footprint. Folded handlebars shrink its width dramatically, and the kick-fold system lets you drop it down with minimal bending over - once you've learned the dance. The "trolley mode", where you roll it on a wheel like a suitcase, is genuinely useful in stations and long corridors. Carrying it up a couple of flights of stairs isn't exactly fun, but it's manageable for most adults.

The KuKirin HX, also a lightweight on paper, feels slightly more substantial because of that fat stem and the concentrated battery mass up top. When you fold it, the latch is simple and obvious - no technique videos required - and the overall package slides easily under seats or into a car boot. Carrying it horizontally, you do notice the front end wanting to dip; you quickly learn where to grab it so it doesn't nose-dive into your shins.

Practicality is where the HX quietly wins many hearts. Being able to leave the scooter locked in a shed, hallway or car park and just take the battery indoors is a real quality-of-life upgrade. No muddy tyres in the lift, no explaining to your partner why the hallway now smells faintly of rubber and regret.

Verdict: If you care about the tiniest possible folded size and like trolley-ing through stations, the Merlin is very good. For everyday living - especially without indoor storage or power - the KuKirin's removable battery and simpler folding make it more practical.

Safety

Safety isn't just about how fast you can stop; it's also about how much grip you have before you need to.

The Merlin II earns points for its triple braking setup and compliant suspension. The combination of regen, drum and foot brake gives you redundancy, and the long wheelbase with low deck keeps things stable at its top speed. The integrated, road-legal front and rear lights are bright enough for typical city use and are always there when you need them.

The weak link is the tyre choice. Those solid rubber wheels are maintenance-free, but in the wet they can feel genuinely nervous. Painted crossings, wet metal covers, smooth tiles - you learn fast to roll off the speed before leaning. The suspension does what it can to keep the contact patch planted, but physics is physics.

The KuKirin HX pairs its disc plus electronic braking with proper air tyres, and that alone gives it a natural grip advantage, especially in the rain. You can brake harder before the wheels start complaining, and mid-corner bumps are handled with far more composure. The headlight sits high on the stem, which actually casts a more useful beam ahead than low deck-mounted lights, and the rear brake light is a nice touch.

That higher-set battery does shift the centre of gravity upwards, but once you're used to it, stability is fine at its limited top speed. The main safety watch-out on the HX is mechanical: you really do want to keep an eye on that stem hardware over time so it never develops play.

Verdict: In dry conditions, they're both fine; in the wet, the KuKirin's pneumatic tyres and stronger braking hardware clearly feel safer and more confidence-inspiring.

Price & Value

This is where things get uncomfortable for the Merlin II.

The Micro sits firmly in the premium price bracket for what is, at the end of the day, a modestly powered, single-motor commuter with a small battery. You're paying for brand heritage, nicer materials, repairability and that suspension squeezed into a low weight. For some riders, that combination is worth it. For many, once you write the numbers next to the spec sheet, it feels a bit like buying a designer briefcase to carry the same documents.

The KuKirin HX, by contrast, undercuts it massively. For a fraction of the price you get a slightly more powerful motor, comfy pneumatic tyres, disc braking and the hugely practical removable battery system. The finishing and long-term refinement aren't in the same league, but purely on "what you get for your euros", it's not a fair fight.

Verdict: The KuKirin HX is the far stronger value proposition. The Merlin II asks you to accept less performance and similar real-world range for dramatically more money, in exchange for brand, suspension and polish.

Service & Parts Availability

This is one of the few areas where the Merlin can justifiably puff its chest out.

Micro Mobility has decades of presence, a proper European support network and a long-standing commitment to spare parts availability. Need a new fender, hinge or light a few years down the line? The odds of getting a genuine replacement without detective work are very high. For risk-averse buyers, that's not trivial.

KuKirin/Kugoo has built up a large global footprint and a huge user base, which translates into good availability of generic parts, third-party spares and plenty of online how-tos. Official after-sales support can vary depending on your retailer and region, and you're relying more on the ecosystem than a white-glove brand experience.

Verdict: Merlin II wins on official, predictable long-term support. KuKirin HX is absolutely serviceable, but expects you to be a little more hands-on or community-driven if things go wrong.

Final Verdict - Which Should You Choose?

If you strip away the brand stories and look at how each scooter behaves as a daily companion, the KuKirin HX feels like the more sensible, rounded choice for most riders. It rides more confidently in the wet, accelerates with a bit more enthusiasm, stops harder, and the removable battery massively simplifies real-world ownership and long-term costs - all at a price that leaves a lot of room in your budget for a good helmet and a spare battery.

The Micro Merlin II is not a bad scooter - far from it. It's light, nicely built, quiet, and its dual suspension in such a small package is legitimately impressive. If you want something that looks and feels premium, appreciate European brand backing, and your rides are short and relatively gentle, you will probably enjoy it. But you are paying a steep premium for refinement and a logo, while accepting less motor, similar or only slightly better real-world range, and tyres that become nervous when the forecast turns grey.

So: if you're a pragmatic urban rider who cares about cost, flexibility and everyday ease of use, go KuKirin HX. If budget is secondary to brand trust, suspension and a tidier, more "grown-up" aesthetic, the Merlin II will scratch that itch - just go in with open eyes about what you're not getting for the money.
