Micro Merlin II vs Riley RS1 - Lightweight Commuter Duel or Race to the Middle?

Fast Answer for Busy Riders ⚡ (TL;DR)

The Riley RS1 takes the overall win here: for a relatively low price you get big, comfortable tyres, a detachable quality battery, solid brakes and enough performance for everyday city use without feeling like a compromise on every corner.

The Micro Mobility Merlin II is the better choice only if ultra-compact folding, trolley mode and full suspension in a very light package are absolutely central to your life - think train-heavy commutes, narrow hallways and lots of stairs.

If you actually care how your scooter rides on real roads, the RS1 simply feels more grown-up and less fragile for less money.

But the story is more nuanced than a simple win-lose scoreboard - stick around and we'll walk through where each scooter quietly shines and where the marketing gloss starts to peel.

Electric scooters in the 13-15 kg class are supposed to be the sweet spot: light enough to carry, serious enough to replace short car or bus trips. On paper, the Micro Mobility Merlin II and the Riley RS1 are textbook examples - both pitched as premium "last-mile" tools rather than toys, both touted as clever solutions for the modern urban jungle.

I've put plenty of kilometres on each, across cobbled old towns, grimy commuter bike lanes and wet tram tracks - the kind of places brochures politely ignore. One of them tries to justify a premium price with Swiss finesse and suspension on tiny, solid wheels. The other leans on big air tyres, a detachable battery and a surprisingly reasonable price tag.

If you want the one-line caricature: the Merlin II is for the commuter who worships portability and doesn't stare too hard at the price tag; the RS1 is for the rider who actually wants their daily trip to feel decent without draining their bank account.

Let's dive in and see where each scooter earns its keep - and where the compromises start to bite.

Who Are These For, and Why Compare Them?

Both scooters live in the compact commuter segment: similar top speeds, similar advertised ranges, similar weights. Neither is trying to be a trail monster or a dual-motor missile, and both are clearly targeting people who mix public transport with scooter miles.

The Merlin II is the quintessential "multimodal" toy-tool: light, very slim when folded, easy to trolley through stations and offices. It's aimed at people who might ride only a few kilometres at a time but absolutely must carry or stash the scooter several times per day.

The Riley RS1 plays in the same sandbox but with a different philosophy: bigger pneumatic tyres, a detachable stem battery and a more down-to-earth price. It's pitched as a practical, everyday vehicle that still fits under a desk, but feels less like a piece of delicate luggage and more like a small, honest vehicle.

They compete because if you're shopping for a quality, light commuter in Europe, both will end up on your shortlist - one for its brand legacy and suspension, the other for its spec-to-price reality check.

Design & Build Quality

In the hand, the Merlin II feels every inch the Swiss product it claims to be: clean lines, restrained colours, tight tolerances. The adjustable telescopic stem and folding handlebars give it a clever, "engineered object" vibe. Nothing wobbles out of the box, and the deck and stem feel reassuringly solid for such a thin, light chassis.

Riley's RS1 goes for a slightly more industrial aesthetic: thicker stem housing the removable battery, a slimmer deck, and that gunmetal finish which looks more "tech gadget" than toy. The aviation-grade frame feels rigid, and the fold latch closes with a confident snap rather than the apologetic click you get on many cheap clones.

Where the Merlin II's design quietly screams portability, the RS1's design quietly screams: "I'm actually meant to be ridden." Cables are neatly routed, the deck rubber is high-grip, and you don't get the sense that one wrong kerb hop will put it out of alignment.

Both are well put together, but there is a difference in what the engineering is optimised for. The Merlin feels like a beautifully finished travel accessory first, scooter second. The RS1 feels like a scooter that someone then worked hard to make easy to live with.

Ride Comfort & Handling

This is where philosophies clash hard.

The Merlin II leans on dual suspension to compensate for its small, solid wheels. On smooth asphalt it actually works: the ride has a soft, springy character and you can feel the suspension doing its best to filter out the chatter. After a few kilometres on rougher city streets, your knees are less angry than they would be on most solid-tyre lightweights.

But there's only so much magic you can wring from little, airless wheels. Hit cracked pavements or irregular cobbles and you start to feel the limits quickly - the suspension moves, but the small contact patch skips and twitches. It's better than a bare solid-tyre scooter by a country mile, but it never quite forgets how small its wheels are.

The RS1 goes the other way: no fancy suspension, just big 10-inch air-filled tyres doing the work. Those tyres are the single biggest reason it's more pleasant to ride day-to-day. They swallow the buzz of coarse asphalt and deal with typical urban imperfections without drama. On the same stretch of broken bike lane where the Merlin II starts to feel nervous and chatty, the RS1 simply glides through with a dull thud or two.

Handling reflects this as well. The Merlin II's low deck and long wheelbase make it reasonably stable at legal speeds, but the small wheels and solid rubber mean you take wet manhole covers and tram tracks with real respect. The RS1, thanks to those larger pneumatic tyres and a low, thin deck, feels more planted. Yes, the stem can feel a touch top-heavy at first because of the battery, but after a few rides it just feels like a normal, slightly eager commuter scooter that doesn't mind being leaned into corners.

In everyday city chaos - potholes, drops off kerbs, surprise patches of rough tarmac - the RS1 is the more forgiving partner. The Merlin II tries hard, but physics keeps reminding you what you're standing on.

Performance

Neither scooter is going to rip your arms off, and that's exactly the point. They're designed to sit happily at regulation city speeds and blend with bicycle traffic.

The Merlin II's motor feels tuned for civility rather than excitement. Acceleration is smooth and predictable; it eases you up to its limit rather than slingshotting you there. In traffic, it's fine - you pull away cleanly from lights, you can overtake slower cyclists, but it never feels eager. On steeper urban hills you'll feel it labouring and gradually bleeding speed, especially with a heavier rider or a backpack full of laptops.

The RS1's motor, with a bit more poke on paper and a similar scooter weight, comes across as livelier. In Sport mode it pulls more strongly off the line, and you hit its top speed confidently rather than with a sigh. On moderate inclines that make the Merlin II feel slightly breathless, the RS1 hangs on better, maintaining speed longer before it starts to sag.

Braking performance is another important part of "real" performance. The Merlin II's combination of regenerative braking, a drum brake and a fender brake reads like a safety brochure. On the road, the regen is pleasantly progressive but the drum needs a firmer hand than you might expect to deliver an urgent stop. It will stop you - just not with much drama.

The RS1's rear disc plus E-ABS front and pedal brake arrangement inspires more confidence when someone opens a car door in front of you. The mechanical bite at the back, combined with controlled electronic braking at the front, gives you stronger, more predictable stopping power. On wet roads, having that extra sharpness is comforting, as long as you're smooth with your inputs.

In terms of overall pace and control, the RS1 feels like it gives you a little extra in all the places you actually notice: getting up to speed, dealing with hills, and shedding speed again when traffic inevitably does something stupid.

Battery & Range

Both scooters quote ranges that, in the best tradition of the industry, are more fantasy novel than technical document. In the real world, ridden briskly by a normal-sized human on mixed terrain, they land much closer together than the marketing suggests.

The Merlin II's battery is modest in capacity but paired with a light chassis and sensible power output. Kept to gentler modes on flatter ground, you can stretch it impressively. Ridden like an actual commuter - full speed where safe, lots of stops and starts, the odd incline - you're realistically looking at a comfortable one-way ride plus some buffer, or a shorter round trip without plugging in.

The RS1's stem battery is slightly smaller on paper but uses quality cells and benefits from efficient power delivery. In practice, your usable distance is broadly similar, maybe a shade less if you're heavy-handed with Sport mode and don't baby the throttle. The difference is how you live with that limitation.

With the Merlin II, the battery is built-in. You take the scooter to the socket - under the desk, into the flat, wherever. With the RS1, you take the battery to the socket. Pop it out of the stem, walk off, job done. It sounds like a minor convenience until you've lived in a third-floor flat with no lift and tried to drag a scooter up and down stairs twice a day.

The RS1's party trick, of course, is that you can carry a spare battery and instantly double your range without changing scooters. That comes at the cost of buying another pack, but it's a flexibility the Merlin II simply doesn't offer.

Both charge quickly enough that an office plug can rescue your afternoon, but in terms of how relaxed you feel about range day-to-day - and how easy it is to keep the scooter juiced without rearranging your life - the RS1's detachable pack is a clear quality-of-life win.

Portability & Practicality

This is the Merlin II's home turf, so let's give it its due.

At around 13 kg and with that ultra-slim folded profile, it's absurdly easy to stash. Folded handlebars make it narrower than most laptop bags, and the trolley mode is genuinely handy in big stations or supermarkets, letting you drag it like slightly awkward luggage instead of heaving it in your arms. Up stairs it's a one-hand carry for most adults, and under-desk living is what it was born for.

The folding mechanism, once you've learned its little quirks, is reasonably quick. The foot-operated latch is clever, if slightly fiddly with chunky shoes. It does at least lock firmly once engaged; you never feel like it's about to unexpectedly unfold on you mid-escalator.

The RS1 is also light enough to carry, but it's not as dainty in its folded footprint. Wider bars, a taller folded height and that thicker stem mean it's more of a normal compact scooter than a "where did it go?" object. That said, we're talking "under desk and into car boot" practical, not "needs its own garage."

Where the RS1 bites back is day-to-day practicality beyond just carrying. The larger tyres mean fewer cringe moments on bad surfaces, the deck is friendlier for bigger feet, and the detachable battery solves a lot of the annoying logistics of charging in small flats and offices. You also don't have to be quite as precious about every puddle or rough patch.

If your life is dominated by stairs, narrow trains and folding the scooter ten times a day, the Merlin II's extreme packability still has an edge. If you mostly wheel it in and out of buildings and up the odd staircase, the RS1 is "portable enough" - and the trade-off in ride quality and everyday ease is worth it.

Safety

Safety is a sum of many small decisions: tyres, brakes, lights, geometry, and how all of that behaves when the road is wet and your attention is split.

The Merlin II scores well on paper: multiple braking options, integrated, road-compliant lighting, and a stable, low-slung chassis. You feel reasonably secure at its modest top speed, particularly in the dry. But the solid tyres are the nagging caveat. On smooth, wet surfaces - painted lines, metal plates, polished stone - they ask for more respect than you'd ideally like. You can ride safely, but you ride more cautiously.

The RS1, with its 10-inch pneumatic tyres, has a built-in advantage the moment the road isn't perfect. The bigger, softer contact patch simply has more grip in more circumstances. Combine that with the stronger disc-and-E-ABS braking setup, and you have a package that feels easier to stop quickly without drama.

Lighting is adequate on both, with integrated front and rear lights and brake-triggered rear signalling. The RS1's beam pattern is decent for being seen and just about adequate for seeing, though you'll still want an extra handlebar light if you ride in truly dark areas. The Merlin's homologated lights tick the regulatory box nicely and are fine for urban lit environments.

Structurally, both scooters feel stiff and predictable at their legal limit. The Merlin's long, low geometry gives a planted feel; the RS1's wheel size and rigid frame provide that "grown-up" stability you want when the surface gets messy.

Between the two, the RS1 feels like the more forgiving scooter when conditions are less than ideal, which - being Europe - is most of the year.

Price & Value

This is where things get a bit awkward for the Merlin II.

It's firmly in premium territory on price - not insane, but definitely "considered purchase" money - yet its motor and battery specs are more in line with mid-range commuters. You're paying for weight, suspension and brand reputation rather than hard numbers. If those things matter to you, the equation can make sense; if you think in euros per watt or per kilometre, it starts to look rather proud of itself.

The RS1, by contrast, sits closer to the budget-mid range border, but brings along proper tyres, decent brakes, a detachable, branded battery and a solid frame. On a spec-sheet-per-euro basis, it lands in a much more comfortable place, especially for a first or second scooter where you're still figuring out how you actually ride.

Over years of commuting, the Merlin's build quality and parts availability do help justify some of the outlay, but it never fully escapes the feeling that you're paying a noticeable premium for lightness and a Swiss logo. The RS1 feels more like a realistic commuter purchase: not cheap junk, not luxury toy, just sensible value with one standout trick (that detachable pack) that genuinely changes ownership.

Service & Parts Availability

Micro Mobility has been around long enough that you can actually get parts when you need them, and not just from whichever anonymous reseller happens to answer an email. Their commitment to full spare-parts availability is a real advantage if you plan to keep a scooter for many years. For European riders especially, that established network and experience count.

Riley is younger but not an unknown start-up in a garage. Support feedback is broadly positive, with clear communication and a repair network that's growing rather than vanishing. The modular battery design is a win here as well: if your pack eventually fades with age, replacing it is straightforward and doesn't feel like performing surgery.

Both are far safer bets than generic white-label scooters in terms of after-sales support. If we're splitting hairs, Micro's longevity and parts catalogues are still a bit ahead. Riley, however, claws back ground by making the main wear item - the battery - user-swappable without tools.

Final Verdict - Which Should You Choose?

If you strip away the marketing and ride both the way real people ride scooters, the Riley RS1 is the more rounded package for most commuters. The big tyres, stronger motor feel, more confident braking and detachable battery address the things you notice every day - comfort, control, convenience and cost. It feels like a practical tool that just happens to be fun, rather than a stylish object that you then have to excuse.

The Micro Merlin II is not a bad scooter; far from it. It's genuinely impressive how much comfort Micro has squeezed out of such a light, compact chassis, and if your commute is dominated by stairs, narrow trains and office corridors, its extreme portability and trolley mode can absolutely justify choosing it. But you do pay handsomely for that convenience, and you live with the compromises of small, solid wheels and modest performance.

So: if you are a multimodal purist who values compactness and brand heritage above all else, the Merlin II still has a clear niche. If you simply want a light scooter that rides well, stops confidently, charges easily and doesn't demand a premium just to turn up, the RS1 is the more sensible - and frankly more enjoyable - companion.

These metrics are all about cold, hard efficiency and cost: how much you pay for energy capacity, speed and range; how much weight you carry per unit of performance; and how quickly you can refill the battery. Lower values are better in most rows (cheaper, lighter, more efficient), while a higher power-to-speed ratio and higher charging speed suggest stronger punch and quicker turnarounds. They don't tell you how either scooter feels to ride, but they show exactly where each one is objectively more or less efficient on paper.
