INMOTION AIR vs SOFLOW SO4 Gen 3 - Two "Serious" Commuter Scooters, One Clear Real-World Winner?

Fast Answer for Busy Riders ⚡ (TL;DR)

If you want the more confidence-inspiring, traffic-ready scooter, the SOFLOW SO4 Gen 3 edges ahead thanks to stronger brakes, higher load capacity, better hill performance and built-in indicators and NFC security. It feels more like a "vehicle" and less like a gadget, especially for heavier riders.

The INMOTION AIR is the better pick if you value low weight, sleek design, cleaner integration and a more polished app, and your rides are short, smooth and mostly flat. It's the easier one to live with if you're carrying it a lot or threading through offices and trains.

Both are competent commuters with notable compromises; neither is a miracle machine. Keep reading to see where each one quietly shines - and where the marketing gloss wears off.

Stick around for the deep dive; the nuances here really matter to choosing the right one for your daily grind.

Who Are These For, and Why Compare Them?

On paper, the INMOTION AIR and SOFLOW SO4 Gen 3 live in the same ecosystem: road-legal, single-motor commuters around the mid-hundreds of euros, capped at bike-lane speeds and aimed squarely at European city riders. Both roll on air-filled 10-inch tyres, both skip suspension to keep cost and weight down, and both promise to be your reliable, no-drama daily transport.

The reality is a bit more nuanced. The AIR leans into the "minimalist, integrated tech toy that happens to commute", while the SO4 Gen 3 tries to be a slightly overbuilt workhorse with better safety hardware and a much higher weight rating. One flatters your inner design nerd; the other flatters your bones when you yank the brake lever in traffic.

They're natural rivals for someone choosing their first "serious" scooter: you're done with rental fleets and cheap clones, but you don't want a 30 kg monster or a four-figure invoice. You just want to survive the commute without a gym membership or a heart attack - and ideally without looking ridiculous.

Design & Build Quality

Pick up the INMOTION AIR and the first thing you notice is how clean it looks. Cables vanish inside the stem, the frame lines are tidy, and there's a quiet confidence to the way everything is integrated. It's the sort of scooter you can park next to a glass office building without feeling like you've brought your kid's toy to work. The aluminium frame feels rigid, the latch closes with a reassuring clunk, and there's very little in the way of rattles once you've put some kilometres on it.

The SOFLOW SO4 Gen 3 takes a different route: function first, then style. You've got visible cabling with green accents, a chunkier stem and a deck that feels like it was designed by someone who has actually seen European pavements. It looks more industrial, less sculpted. Not ugly - more like a power tool with lights. Welds and frame thickness inspire confidence, especially when you remember it's rated to carry significantly more weight than the AIR.

In the hands, the AIR feels more "finished" and refined, the SO4 more rugged and utilitarian. The AIR wins on visual polish and cable management; the SoFlow counters with hardware that looks like it could shrug off a few more years of abuse and heavier riders. If you're picky about aesthetics, the AIR has the edge. If your priority is "will this thing complain when I put a big backpack on?", the SoFlow's overbuilt stance is more reassuring.

Ride Comfort & Handling

Neither scooter has mechanical suspension, so your ankles, knees and tyre pressures are doing the heavy lifting. On smooth tarmac and decent bike lanes, both are absolutely fine - even pleasantly smooth. Once the surface deteriorates, the differences start to show.

The INMOTION AIR feels light and nimble. The steering is quick without being twitchy, and the relatively low weight makes it easy to flick around potholes or thread through street furniture. On mildly broken city surfaces, the combination of air-filled tyres and low mass keeps things tolerable. Spend a few kilometres on aggressive cobblestones, though, and you'll start rehearsing a breakup speech with your joints. It's liveable for short hops, not something you'd choose for a long scenic torture session.

The SOFLOW SO4 Gen 3, being a touch heavier and built for higher loads, feels more planted. The wider deck lets you adjust your stance more comfortably, which matters when you're using your legs as suspension. On the same stretch of roughish pavement, it feels more stable and less skittish; you're still very aware of big bumps, but the chassis feels less nervous when you hit them. The trade-off is that darting through very tight gaps takes a little more deliberate input.

In handling terms, the AIR is the agile city scalpel, the SO4 Gen 3 the slightly heavier, calmer commuter that shrugs off imperfections a bit better. Neither turns bad cobbles into a magic carpet, but the SoFlow's footprint and deck ergonomics make it easier to stay relaxed when the surface misbehaves.

Performance

In the performance department, both scooters play within the same legal sandbox, but they don't feel identical on the road.

The INMOTION AIR's rear motor has a modest nominal rating with a surprisingly decent peak punch. Off the line it's lively enough for city use: you'll beat most bicycles away from a light without sweating, but you're not exactly tearing holes in space-time. The throttle tuning from INMOTION is nicely sorted - power comes in smoothly, with no jerky on/off surges. It reaches its capped top speed with little drama and then just sits there, quietly doing its job. On moderate hills, it will climb, but heavier riders will notice it digging deep and bleeding speed.

The SOFLOW SO4 Gen 3 steps things up slightly in the torque department. The motor is stronger on paper and feels that way in practice, especially with heavier riders. You get a firmer shove off the line and more determination on inclines. It still lives in the regulated speed band, so you won't go dramatically faster on the flat, but getting up to that speed - particularly on slopes and with a heavy load - feels less like asking a favour and more like the scooter doing what it was built for. Even near its stated weight limit, it keeps chugging where a lot of cheaper commuters start to wheeze and sulk.

Braking is where the difference really bites. The AIR's combo of rear regenerative braking and a front drum is smooth and low-maintenance. It's very civilised: you pull the single lever, you feel magnetic drag first, then a progressive mechanical bite. It's friendly and hard to seriously mess up, but you don't get that aggressive, confidence-in-any-situation stopping feel of dual discs.

The SO4 Gen 3's twin mechanical discs are much more serious. You have real bite at both ends, and emergency stops feel notably shorter and more controlled once the brakes are correctly adjusted. The downside: mechanical discs can squeak, go out of alignment and demand the occasional hex key session. In other words, more peace of mind while riding, a bit less peace of mind if you hate maintenance.

If you're light and live on the flat, both are "quick enough" for commuting. If you're heavier or surrounded by hills, the SoFlow's stronger motor and dual discs make life noticeably less stressful.

Battery & Range

This is where both scooters are a bit... 2020s budget rather than future-proof. Neither battery is huge for the price class, and both brands lean on "under ideal conditions" marketing. In the real world, those conditions rarely involve wind, hills, traffic or human riders.

The INMOTION AIR's pack is on the small side, but paired with a relatively efficient setup and a light frame. In real-world city use, ridden assertively, you're looking at commutes in the low-to-mid-teens of kilometres with a safety buffer, or a bit more if you ride gently and you're light. It's perfectly fine for most inner-city trips, and you can usually skip charging for a day or two if your commute is short. Range anxiety exists if you're stretching its limits, but at least the power delivery stays fairly consistent until you're genuinely low.

The SOFLOW SO4 Gen 3 uses a battery of similar capacity but asks more of it. That stronger motor and higher weight rating draw more current, and the claimed maximum range is optimistic at best. Add in a heavy rider or a hilly city, and you'll often see the battery gauge dropping faster than you'd like. Realistically, treat it as a short-to-medium hop machine: fine for daily there-and-back commutes in the mid-teens of kilometres if you can charge at one end, but not a Sunday explorer.

Charging times are roughly comparable: both will go from flat to full somewhere in the "leave it for half a workday or an evening" window. The AIR tends to take a touch longer per Wh, the SoFlow a touch quicker, but not enough to change your life. If you're the type who always plugs in at the office or overnight, both are manageable. If you're hunting big range in this price bracket, though, neither of these is the class leader.

Portability & Practicality

The INMOTION AIR has clearly been designed by someone who has experienced European staircases. It's usefully lighter than the SoFlow and noticeably easier to carry one-handed. The folded package is compact, the stem hooks securely to the rear, and you can navigate station escalators and office corridors without feeling like you're dragging a reluctant Labrador. Under a desk or in a small boot, it disappears fairly politely.

The SOFLOW SO4 Gen 3 sits a kilo or so heavier, which doesn't sound like much until you've done three flights of stairs at the end of a long day. It's still within what most adults can manage, but if you're smaller or less strong, you won't mistake it for an ultra-light device. The non-folding bars make it a bit wider when folded, so wedging it into cramped spaces or busy trains is slightly more awkward.

On the everyday practicality front, the tables turn a little. The AIR is wonderfully low-maintenance: no exposed discs to tweak, no suspension bearings to groan, hidden cabling safe from snags. Check tyre pressure, occasionally glance at the drum brake, and that's about it. The app is actually useful: motor lock, firmware updates, adjustable acceleration, proper battery readouts - it all helps.

The SO4 Gen 3 adds features that feel far more "transport" than "toy": built-in indicators, dual discs, NFC immobiliser, legal compliance in strict markets. That's the stuff you appreciate when you're using the scooter daily in traffic, even if the app is a bit more hit-and-miss and the discs occasionally demand attention. For multi-modal commuters who carry their scooter a lot, the AIR is the friendlier choice. For pure door-to-door riders who mostly roll rather than lift, the SoFlow earns its keep.

Safety

Safety is one category where the spec sheets actually line up with seat-of-the-pants impressions.

The INMOTION AIR takes a more subtle, software-driven approach: that blended regen-plus-drum system, decent headlight with respectable throw, side reflectors, a braking tail light and a reasonably rigid chassis with a solid latch. Water protection is decent for city showers, and the handling is predictable enough that you're unlikely to surprise yourself in a bad way. It's a calm, forgiving scooter that doesn't ask for heroic skills to ride safely.

The SOFLOW SO4 Gen 3 comes at it like a checklist written by a traffic inspector. Dual disc brakes? Check. Integrated bar-end indicators so you can keep both hands on the grips? Check. Bright, certified rear light? Check. Beefy frame, higher load tolerance, fat deck? Check. Add the NFC immobiliser (which is more security than safety, but still) and you end up with a scooter that feels purpose-built for mixing with cars and buses, not just pottering down park paths.

In the wet, both benefit from their air tyres but require your common sense. The SoFlow's discs give more outright stopping power and feedback; the AIR's system is more linear and less likely to lock the front if you panic-grab, especially for inexperienced riders. Overall, if you're riding in busy traffic, the SO4 Gen 3's combination of stronger brakes and built-in indicators is hard to ignore.

Community Feedback

Price & Value

Both scooters live in that frustratingly crowded "mid-range commuter" price band, where every brand claims to be the perfect balance of everything. Neither is outrageously overpriced, but neither is an obvious bargain either.

The INMOTION AIR costs slightly less, offers a nicely finished frame, tidy integration and a refined control system. On the other hand, its battery and power figures are conservative, and there are competitors in this price area that give you more range or more punch - just without the same elegance and brand polish. You're paying for refinement and low-maintenance ownership rather than raw distance or speed.

The SOFLOW SO4 Gen 3 asks a bit more money but brings dual discs, indicators, NFC and a far higher load capacity. For an average-weight rider chasing maximum range per euro, that premium isn't particularly compelling; you can get scooters that go further for the same money. For heavier riders, though, the calculus flips completely: there simply aren't many scooters at this price that are officially comfortable carrying that kind of weight while remaining street-legal.

In short: AIR is better value for lighter, style-conscious commuters who carry their scooter. The SoFlow makes more financial sense if you're heavier, hill-bound or putting safety hardware at the top of your list.

Service & Parts Availability

INMOTION has built a decent network in Europe through distributors and PEV specialists. Parts aren't as ubiquitous as Xiaomi spares, but you're unlikely to be completely stuck if something breaks. Electronics have a good reputation from their unicycle world, and issues like firmware updates are usually handled reasonably quickly. Most routine consumables - tyres, tubes, generic components - are standard sizes.

SoFlow, being strongly focused on the DACH region, is reasonably visible in shops there, but user reports on customer support are more mixed. Some riders get their issues handled smoothly; others complain about slow turnaround and parts delays. The SO4 Gen 3 isn't wildly exotic in its construction, but things like proprietary stems, dashboards or indicator modules will likely need to come from SoFlow or a partner, which can mean waiting if you're unlucky.

If you prioritise smooth after-sales experience, INMOTION currently enjoys a slightly better reputation. If you live in a city where SoFlow has a strong retail presence, that gap narrows - just don't assume the "Swiss" label automatically guarantees premium support.

Pros & Cons Summary

Parameters Comparison

Final Verdict - Which Should You Choose?

Both scooters occupy that slightly frustrating "good but not game-changing" tier - capable commuters with obvious strong points and equally obvious compromises. The trick is matching those compromises to your life.

If you're an average-weight rider, mostly on decent infrastructure, and you regularly have to carry your scooter into buildings or onto trains, the INMOTION AIR is simply easier to live with. It's lighter, neater, and demands less fettling. The ride is calm, the app is useful, and it looks like it belongs in a modern office. You sacrifice some brute strength, ultimate braking power and heavy-rider capability, but for many urbanites that trade-off is perfectly acceptable.

If you're heavier, tackle serious hills, or ride in mixed traffic where indicators and strong brakes are more than just nice extras, the SOFLOW SO4 Gen 3 is the more convincing package. It feels sturdier under load, hauls weight with more confidence, and its safety hardware makes a tangible difference in everyday commuting stress. You pay a bit more, carry a bit more, and accept a slightly underwhelming range for the price - but in return you get a scooter that feels less like it's working at the edge of its comfort zone.

Viewed as complete packages, the SOFLOW SO4 Gen 3 takes the overall win for serious, safety-conscious commuting, especially for heavier riders and hillier cities. The INMOTION AIR remains a strong alternative if portability, polish and lightness are your top priorities and your daily ride is short, smooth and civilised.

Based on the scoring, the INMOTION AIR is our overall winner. Ridden back-to-back, the SOFLOW SO4 Gen 3 feels more like a grown-up commuter tool: it stops harder, carries more, copes better with hills and gives you just that little bit more peace of mind when cars are close and the tarmac is ugly. The INMOTION AIR, in contrast, charms with its lightness and polish - it's the one you'll enjoy carrying and threading through the city, as long as your journeys stay within its comfort zone. For most serious daily commuters, especially heavier riders, I'd lean toward the SoFlow as the more complete "vehicle", warts and all. The AIR is the nicer object and often the nicer companion if your rides are short, civil and interspersed with stairs and trains - but when the city gets messy, the SO4 Gen 3 is the one I'd rather be standing on.

That's our verdict when we try to stay objective – but hey, riding is mostly about emotions anyway, so pick the one that will make you look forward to your commute every single day.
