IENYRID M4 Pro S vs KUKIRIN M4 Max - Which "Budget Beast" Actually Deserves Your Money?

Fast Answer for Busy Riders ⚡ (TL;DR)

The KUKIRIN M4 Max edges out the IENYRID M4 Pro S as the more rounded scooter, mainly thanks to its stronger real-world range and slightly more mature execution of an otherwise very similar concept. If you want a long-legged, cushy, fast commuter that can handle rough city streets without constant range anxiety, the M4 Max is the safer bet.

The IENYRID M4 Pro S still makes sense if you're chasing the lowest purchase price, love the idea of a seated setup out of the box, and don't mind doing some tinkering to get it dialled in. It's the "project scooter" of the two.

Both are fast, heavy, and firmly in the "mini-moped in disguise" category, not toys-so pick based on how much range and refinement you really need, and how much faffing with tools you're willing to accept.

Read on if you want the full, brutally honest rider's-eye comparison before committing your hard-earned € to either of these "budget performance" legends.

They look almost identical on paper: chunky 10-inch tyres, full suspension, around 800 W at the rear wheel, and speeds that put them well beyond rental-scooter territory. The IENYRID M4 Pro S and KUKIRIN M4 Max both promise "big scooter energy" for mid-range money, and both have fan communities willing to swear they're the best value ever made.

After spending real kilometres on both, the reality is a bit more nuanced. Yes, they're fast. Yes, they're fun. But they're also heavy, a bit rough around the edges, and demand at least a basic relationship with an Allen key. They occupy that awkward middle ground between polished commuter and full-on hooligan machine.

Think of the IENYRID as the more "DIY, have-a-fiddle" option and the KUKIRIN as its slightly better-fed cousin that's learned a few manners. Let's dissect where each one actually shines - and where the marketing gloss wears off once the road gets bumpy.

Who Are These For, and Why Compare Them?

Both scooters target riders who are bored of slow, wobbly 25 km/h commuters but not ready (or willing) to cough up for premium dual-motor monsters. They sit in that mid-priced zone where you expect real power, suspension that does more than pretend, and enough range to make a proper commute without playing "battery roulette" on the way home.

You get similar weight, similar claimed speed, similar motors, and similar general idea: one big rear motor, big tyres, decent suspension, seat-capable chassis and proper lighting. They're clearly aimed at the same rider: someone who wants to replace short car or bus trips, ride in mixed conditions, and occasionally have a bit of childish fun leaving rental scooters for dead at the lights.

Comparing them head-to-head makes sense because, for most buyers, you're not asking " Is this class right for me?" but " Which version of this same idea sucks less over time?" That's where the differences start to matter.

Design & Build Quality

Put them side by side and the family resemblance is... not subtle. Both have that industrial, slightly over-eager stance: exposed springs, wide decks, beefy stems and enough metal to make a Brompton owner faint.

The IENYRID M4 Pro S leans slightly more "budget hot-rod". Its frame is all-aluminium, with loud accent colours and flashy deck lighting that practically screams, "look at me, I cost less than you think." It's not delicate, but you do notice the budget in the small things: some plastics feel a bit cheap, and fresh out of the box there's a decent chance you'll find a bolt or two that needs some persuasion to behave.

The KUKIRIN M4 Max goes for a more utilitarian vibe. The combination of aluminium and steel gives it a chunkier, more serious feel. The finishing is a touch more mature: the deck rubber is a bit nicer, the rear fender tends to feel more solid, and overall there's slightly less of that "mail-order project" aura. It still needs a once-over with tools, but it feels less like a kit and more like an actual product.

Neither hits premium territory; you're not getting Inokim or Nami refinement here. But if you had to bet on which one will shrug off abuse longer before developing creaks and rattles, the KUKIRIN has the edge in sheer structural solidity. The IENYRID feels a bit more cobbled together - not unsafe, just clearly built to hit a price.

Ride Comfort & Handling

On rough urban tarmac, both scooters are comfortable enough that you'll start voluntarily aiming for the smoother line rather than needing it. They're miles ahead of stiff, small-wheel commuters when it comes to soaking up potholes, manhole lips and dodgy curb ramps.

The IENYRID M4 Pro S leans heavily on its "triple shock" setup, especially if you're using the seat. Standing, it does a good job of ironing out chatter, but the front end can feel a little noisy and busy over repeated hits - more clunk and squeak than glide. With the seat installed, the extra springing under your backside does help on longer rides, but it also emphasises that this is not a finely tuned suspension system; it's more "brute force comfort" than elegance.

The KUKIRIN M4 Max, with its dual-fork front and hefty rear springs, feels a touch more composed. Where the IENYRID can feel like it's bouncing over rough stuff, the M4 Max has a slightly better-controlled stroke. Hit a sharp pothole at pace and the KUKIRIN recovers faster and with less drama through the bars. Over a few kilometres of broken pavement or cobbles, my knees and wrists felt marginally fresher on the KUKIRIN.

In terms of handling, both are heavy scooters with big tyres, so don't expect nimble, bicycle-like flickability. They like wide, smooth arcs rather than tight slalom work. The IENYRID's cockpit, especially with the seat, can feel a little taller and more "perched", which takes a moment to adjust to if you push it into corners. The KUKIRIN feels slightly more planted at speed; the stem and hinge area simply inspires a bit more confidence when you're nudging the top of the speed range.

Comfort verdict: both are pretty plush for the price, but the KUKIRIN's suspension tuning and overall composure over bad surfaces are a step ahead. The IENYRID is comfortable, just a bit more crude about it.

Performance

On paper, both have an 800 W rear hub. On the road, they behave like close cousins: plenty of poke for city riding, and enough top speed that you're very aware your body is the crumple zone.

On the IENYRID M4 Pro S, acceleration in the highest mode is genuinely lively. From a standstill, it surges forward with an eagerness that will surprise anyone upgrading from a rental scooter. It's easy to spin up to traffic speed and slip into the flow, and on moderate hills it keeps chugging without the humiliating "step off and push" moment. The throttle is on the lively side but not totally binary-provided you respect it and don't jab it like a video-game trigger, it's manageable.

The KUKIRIN M4 Max feels broadly similar off the line - brisk, torquey, and perfectly happy shoving a heavier rider up an incline. Its controller tuning feels a hair smoother; power comes in a bit more progressively, which makes it easier to hold a precise speed, especially when balancing in slower traffic or in bike lanes. On steeper climbs the difference isn't night and day, but the KUKIRIN feels slightly less strained when loaded up, especially as the battery starts to drop.

At higher speeds, both will happily run at their claimed ceiling on the flat with an average-weight rider. The difference is confidence, not capability. On the IENYRID, top-speed runs feel "fun but busy" - you're aware of every little wobble or vibration. On the KUKIRIN, the chassis feels a tiny bit calmer and the tubeless tyres add just enough extra reassurance that you're less distracted by "what if I hit something?" thoughts.

Braking is strong on both - dual mechanical discs plus electronic assistance will haul you down hard if you grab a handful. Neither has the lever feel of a good hydraulic setup, but for the money they're entirely acceptable. The IENYRID's E-ABS can feel slightly more intrusive; on the KUKIRIN, the blend of mechanical and electronic braking feels a little more natural once the pads are bedded in.

Overall, performance is a split decision: raw shove is comparable, but the M4 Max delivers its power with a fraction more polish, which matters more than spec sheets once you ride them back-to-back.

Battery & Range

This is where the KUKIRIN M4 Max stops playing nice and simply walks away.

The IENYRID M4 Pro S can be had in two battery flavours. The smaller pack is fine for everyday commuting if your return trip is modest and you don't ride flat-out everywhere. Even ridden fairly hard, it'll cover a typical city round-trip without drama, but you won't be taking the scenic route and then running extra errands with carefree abandon. You're conscious of the gauge once you've done a couple of brisk legs.

The larger "Max" battery option on the IENYRID closes the gap a lot, and with that version you can realistically plan longer days out - but then the price gap to the KUKIRIN starts to narrow, and the whole value equation gets murkier.

The KUKIRIN M4 Max comes with a substantially bigger battery as standard. In practice, that means you can hammer it in the fastest mode, take hills as they come, and still have a decent reserve at the end of a long commute. It's the sort of range where you can commute all week with slightly shorter legs, or every other day with longer ones, without babying the throttle or living in Eco mode.

The downside: the KUKIRIN's bigger pack also takes longer to charge. You're squarely in "overnight-only" territory. The IENYRID's smaller pack, by comparison, feels more forgiving if you're the type who occasionally forgets to plug in and needs a full refill in a shorter window.

But if we're talking pure distance on real roads at real speeds, the KUKIRIN is comfortably ahead. If range matters, it's the obvious winner.

Portability & Practicality

Here's the reality: neither of these is a "carry it onto the metro one-handed" scooter. They both sit in that bulky, 24 kg class where folding is more about storage and car transport than true portability.

The IENYRID M4 Pro S folds reasonably quickly. The stem collapses, the handlebars fold, and you end up with a chunky but manageable package that will slide into most car boots and under larger desks. Carrying it up a flight of stairs is a workout, two flights is an exercise regime. Add the seat post and you're juggling even more awkward hardware unless you remove it.

The KUKIRIN M4 Max uses a quick-fold system at the stem base and folding handlebars too, and in daily use it feels a touch more civilised. The folded dimensions are very similar, but the locking and lifting arrangement is slightly better thought out. You can grab it by the stem with a bit more confidence, and the hinge feels less "please don't rattle loose on me" over time.

In day-to-day practicality, both offer similar IP ratings, similar mudguard effectiveness (once you've made sure they're secured), similar kickstands and similar "this is a small moped" weight. The difference is that the KUKIRIN feels more like a finished, integrated product, while the IENYRID feels like something you adapt to your life with a few DIY tweaks.

Safety

Safety on this class of scooter boils down to three big things: can you stop, can you see, and can others see you?

Braking, as mentioned, is decent on both. Twin mechanical discs plus electronic assistance give plenty of stopping power, and once you've bedded the pads in and adjusted the cables, both scooters can pull up hard enough to make you appreciate having good shoes. Neither is immune to cable stretch, so regular checks are non-negotiable.

Lighting is actually a strong point on both machines. The IENYRID M4 Pro S goes full sci-fi with its side light strips and multi-colour accents. At night you're extremely visible - borderline over-the-top, but in the best possible way. The main headlight throws a usable beam for urban speeds, though I'd still add an extra bar light if you regularly ride unlit paths.

The KUKIRIN M4 Max is similarly blinged up with underglow-style deck lighting, integrated indicators and a solid front light. Visibility from the sides is excellent, which is more important in the real world than absolute lumen numbers. Overall, both scooters make you stand out far more than standard "tiny tail light and token headlamp" commuters.

Tyres and stability tip slightly towards the KUKIRIN. The tubeless off-road tyres reduce the chance of sudden, catastrophic deflation and offer slightly more forgiving grip on sketchy surfaces like wet leaves or gravel. The IENYRID's pneumatic tyres are fine, but tube-type punctures can go from "that's odd" to "I'm riding on the rim" more quickly.

In terms of chassis stability at speed, again, the KUKIRIN feels marginally more locked-in, while the IENYRID can develop a stem wobble if ignored. In both cases, diligent bolt-checking and proper tyre pressure are key. If you're the type who never checks anything, neither of these scooters is really for you - but you'll get away with negligence slightly longer on the KUKIRIN.

Community Feedback

Price & Value

The IENYRID M4 Pro S undercuts the KUKIRIN M4 Max on sticker price. On a tight budget, that matters. You're getting big power, real suspension, strong lighting, and a seat option at a cost where most mainstream brands are still selling underpowered, rigid commuters.

But the cheaper entry price doesn't tell the whole story. Add the larger battery option, maybe a few bits to quieten rattles or deal with punctures, and the total cost creeps closer to the KUKIRIN. Meanwhile, the M4 Max is offering its big battery and solid overall package from the get-go. You pay more upfront, but you're not left thinking about upgrading after a few months because the range is annoying you.

From a pure "what do I get per Euro" perspective, the KUKIRIN actually feels like the better long-term deal if you're genuinely going to ride often and far. The IENYRID is the stronger choice if you want to spend the minimum possible today and don't mind living with a bit less refinement and more DIY.

Service & Parts Availability

Both brands are very clearly in the "aggressive online pricing, light-touch after-sales" camp. You're not buying from a local dealer who'll lovingly true your brakes every six months; you're buying from a warehouse and an email form.

IENYRID has a decent presence across major marketplaces, and parts are usually findable if you're patient. Support stories are mixed: some riders get prompt help and spares, others experience slow responses and fairly generic troubleshooting.

KUKIRIN, having been around a bit longer under various names, benefits from a slightly deeper ecosystem. There are more third-party parts, more how-to videos, more forum posts, and generally a bigger knowledge base. European warehouses also help with faster shipping on both scooters, but KUKIRIN's scale gives it a small edge in long-term survivability and parts availability.

In both cases, you should expect to be your own first-line mechanic. If that thought horrifies you, you might want to look at something sold through a proper local shop instead.

Final Verdict - Which Should You Choose?

Both the IENYRID M4 Pro S and the KUKIRIN M4 Max live in that slightly scruffy "budget bruiser" category: fast enough to be serious, refined enough to commute on, but still built to a price that shows in the details.

If your budget ceiling is hard and low, and the idea of getting big power and comfortable suspension for as little money as possible makes you smile, the IENYRID M4 Pro S will absolutely scratch that itch. It's quick, it's cushy, the lighting is hilarious in the best way, and with a bit of mechanical affection it can be a very satisfying daily machine - especially if you value the included seat and high load rating.

But if you're asking which one I'd personally want to live with long-term as a main commuter, it's the KUKIRIN M4 Max. The extra range reduces day-to-day stress, the ride is calmer at speed, the tubeless tyres are a meaningful upgrade, and the general feel is that of a scooter that's been thought through one iteration further. It still isn't a paragon of polish, but it feels less like a rolling compromise.

So: tinkerers, bargain hunters, and shorter-distance riders will be perfectly happy on the IENYRID. Riders who want to ride further, fuss less, and have a slightly more confidence-inspiring partner for the daily grind will be better served by the KUKIRIN M4 Max.
