SOFLOW SO4 Gen 3 vs XIAOMI 4 Pro - Which "Serious" Commuter Scooter Actually Earns Your Money?

Fast Answer for Busy Riders ⚡ (TL;DR)

The Xiaomi 4 Pro is the more complete everyday scooter for most riders: it goes noticeably further, feels more refined, and benefits from Xiaomi's huge ecosystem of parts, know-how and community support. It's the predictable, low-drama choice if you just want a reliable commuter that quietly does its job for years.

The SOFLOW SO4 Gen 3, on the other hand, makes sense if you are a heavier rider or regularly haul serious weight and care more about load rating, dual disc brakes and built-in indicators than about long range. It's a sturdier "tool" than it is an exciting gadget.

If you want polished range and reliability, lean Xiaomi. If you're heavier, very safety-focused, and your daily distance is short, the SoFlow can still be a rational pick. Now let's dig into the nuances, because that's where the real decision lives.

You see these two a lot on European comparison lists: big brand versus "Swiss" commuter specialist, both promising to be the one scooter you actually use every day, not just in the honeymoon week. I've put plenty of city kilometres on both, from cold morning commutes to late-night sprints home when the last tram has already given up.

On paper they're in the same broad class: legal top speed, no suspension, similar weight, mid-range pricing. In practice, they go after slightly different riders. One is very much the refined all-rounder; the other is the rule-abiding workhorse with a gym membership.

If you're torn between them, stay with me: the differences aren't flashy, but they matter a lot after a few hundred kilometres of real-world use.

Who Are These For, and Why Compare Them?

Both scooters live in that "serious commuter, but not a monster" category. They top out at standard European speeds, keep roughly the same footprint, and weigh enough to feel like vehicles rather than toys, but not so much that your staircase becomes a daily leg workout plan.

The Xiaomi 4 Pro is aimed at the everyday urban commuter who cares about range, polish and resale value. Think office worker or student doing a decent round trip, mostly on tarmac, who wants as little drama as possible.

The SOFLOW SO4 Gen 3 clearly targets heavier riders and ultra-rule-compliant markets. High load rating, very "German-legal" approach, turn signals, dual discs - it feels like it was designed in a meeting where lawyers and safety engineers had more votes than marketers.

They compete because, at the shop shelf, they sit in the same mental bucket: "good" commuters that are supposed to replace buses, not just supplement them. They just prioritise different compromises.

Design & Build Quality

In the flesh, both scooters feel solid, but they wear their priorities differently.

The Xiaomi 4 Pro has that familiar Xiaomi minimalism: matte frame, understated accents, clean cable routing, integrated display that looks like it belongs there, not like an afterthought stuck on the bar. It has the "consumer electronics" vibe - like your phone grew wheels. Welds are clean, there's very little flex in the stem, and nothing rattles unless you've abused it.

The SOFLOW SO4 Gen 3 goes for "utilitarian with a marketing degree." Matte black frame, bright green touches, fairly chunky stem. Up close, it feels robust more than pretty - you get the sense that someone was far more worried about bending than about winning design awards. The welds and the thickness of the tubes do inspire confidence, especially if you're on the heavier side.

The folding mechanisms underline the difference. Xiaomi's updated latch feels well-engineered and reassuring; it folds with a clean, repeatable motion that doesn't make you nervous. The SoFlow's base-stem lever is simpler and solid enough but lacks that polished, "thunk" precision. It works, it's safe - it just doesn't feel special.

Overall build quality? Both are decent by commuter standards. The Xiaomi feels more refined and tightly engineered; the SoFlow feels more industrial and overbuilt where it matters for weight and legal compliance.

Ride Comfort & Handling

Neither of these has mechanical suspension, so you're very much in tyre-suspension territory. The question isn't "plush or not", it's "how tolerable is the daily beating?"

On the Xiaomi 4 Pro, the larger tubeless tyres and wider cockpit make a surprisingly big difference. On half-decent city tarmac and bike paths, it really does "glide" more than you'd expect from a rigid frame. The wider deck and bars let you relax your stance, and the scooter feels planted rather than skittish. When the surface gets bad - cobbles, broken asphalt, tree-root bulges - you still feel the hits clearly, but the chassis behaves predictably, without nasty kicks or wobble.

The SOFLOW SO4 Gen 3 runs similarly large pneumatic tyres, and they do a good job taking the edge off cracks and smaller imperfections. The wide deck is genuinely nice; feet can be side-by-side or staggered without feeling cramped. On smoother surfaces, it's fine - not magical, not terrible. On rougher stretches, the lack of suspension is more obvious than on the Xiaomi, partly because the steering setup feels a bit less refined. Hit a deeper pothole or a sharp curb and the impact reaches your knees in a very direct way.

Handling wise, the Xiaomi feels slightly more composed and neutral, especially at speed or in sweeping turns. You get the sense the whole geometry was tuned to be forgiving. The SoFlow feels stable in a straight line, but its steering can feel a tad heavier and less precise; some units even arrive with overly stiff bearings, and you can feel that in quick direction changes.

So for comfort and handling on typical European city surfaces, the Xiaomi edges ahead. The SoFlow is acceptable for shorter rides, but you feel its compromises sooner on bad pavement.

Performance

Both scooters are electronically capped to the same legal top speed in Europe, so this isn't a drag-race story. The difference is in how they get there and how they cope with hills and heavier riders.

The Xiaomi 4 Pro accelerates with an easy, confident push. In its sportiest mode it zips away from lights quickly enough to beat most cyclists, but the power delivery is smooth rather than dramatic. There's a pleasant sense of "reserve" - it doesn't feel like the motor is screaming for mercy even after a long hill or with a moderately heavy rider on board.

The SOFLOW SO4 Gen 3, with its torque-tuned motor, actually feels fairly willing off the line too. Up to its limited speed it pulls decently, and for legal commuting it doesn't feel underpowered. Its party trick is low-speed grunt under high load: if you're closer to its impressive weight limit, it doesn't collapse into a wheezing crawl the way many cheaper commuters do. It will climb realistic city inclines with determination rather than shame.

But once you're at cruising speed, the Xiaomi just feels more relaxed and composed. It holds pace with less sense of strain, and the power drop-off as the battery empties is more subtle. The SoFlow can feel like it's working harder relative to its smaller battery - it does the job, just not with the same effortless character.

Braking is strong on both, but with a different flavour. The SO4's twin mechanical discs give you very direct, "old school" control - lots of bite, plenty of stopping power, but they can be squealy or need a tweak now and then. The Xiaomi mixes a larger rear disc with front regenerative braking, which feels more sophisticated: you get an immediate electronic drag in the front and strong mechanical bite at the rear, with less tendency to lock or skid on damp markings.

For day-to-day performance, especially for average-weight riders, the Xiaomi simply feels more refined. The SoFlow is respectable and especially friendly to heavier riders, but there's no "wow" factor beyond its willingness under load.

Battery & Range

This is where the two scooters stop playing in the same league.

The Xiaomi 4 Pro carries a significantly larger battery and it behaves exactly like you'd expect: in real life you can often cover a decent round-trip commute on one charge, even if you ride briskly. For many people that means charging either overnight or just at work, not nervously watching the battery bars halfway home. Ride in the more moderate mode and avoid constant full-throttle abuse, and you're realistically looking at several days of short commutes between charges.

The SOFLOW SO4 Gen 3, by contrast, has a clearly smaller pack. The marketing range figure is optimistic, and owners know it. Ridden like people actually ride - full legal speed, stop-and-go, maybe a hill or two - you're much closer to what I'd call "city-core radius": enough for a short commute or errands, but you'll be plugging it in pretty much daily. If you're heavy or live in a hilly city, your usable window shrinks further.

Charging is quicker on the SoFlow; you can top it in a normal workday or a long afternoon fairly comfortably. The Xiaomi's larger pack takes a solid overnight or full office-day to refill. But the reality is: most commuters care more about how far it goes than how fast the charger finishes at 23:30.

If you want to forget about range most days, the Xiaomi wins hands down. The SoFlow feels fine for short, predictable hops, but it's not the one you take when a friend texts you from the other side of town.

Portability & Practicality

On the scales they're surprisingly close, and in the hand they're both firmly "carryable, but not gracefully" territory. One flight of stairs, fine. Four floors daily, and you'll question your life choices either way.

The Xiaomi 4 Pro carries its weight in a slightly longer, more substantial frame. The updated folding mechanism is quick and confidence-inspiring; once folded, it clicks together neatly and is reasonably manageable to carry one-handed for short distances. It's not tiny - on a packed metro at rush hour you'll still be that person people shuffle around - but it's workable.

The SOFLOW SO4 Gen 3 is marginally lighter on paper, and that does help a bit when you have to heave it into a car boot. However, the non-folding handlebars make it feel bulkier sideways, which you really notice trying to thread yourself through train doors or fit it behind an office desk. The folding joint itself is fine, just not particularly compact or elegant.

In terms of living with them day to day, the Xiaomi's slightly more polished folding and slimmer folded profile make it the easier companion if your routine involves regular multi-modal transport. The SoFlow is fine if your "portability" mostly consists of getting it through your front door and into the lift.

Safety

Both scooters put a strong emphasis on safety, but in subtly different ways.

The SOFLOW SO4 Gen 3 leans on hardware quantity: dual disc brakes, bright lighting, integrated turn signals in the bar ends, high load rating, and a solid stance on those larger tyres. You never feel like the structure is protesting under you, even if you're closer to its maximum rated load. The NFC immobiliser is a nice touch too - tap, it's locked, and casual thieves are out of luck.

The Xiaomi 4 Pro leans more on overall systems: integrated regenerative plus mechanical braking, bright headlight, clear tail light, and (on the newer variants) its own handlebar indicators. The self-sealing tubeless tyres are a big safety upgrade in their own right: fewer sudden flats, fewer sketchy rides home on half-deflated rubber. The chassis' calm behaviour at top allowed speed and over small debris inspires confidence.

Lighting is solid on both. The Xiaomi's beam pattern feels a bit more refined, and the automatic brake-flash on the rear is nicely tuned. The SoFlow's lights do the job and the indicators are very visible - it just all feels a bit more "functional" rather than "engineered to death".

If you're a very heavy rider worried about structural safety and brake hardware, the SoFlow's package is reassuring. For everyone else, Xiaomi's combination of braking behaviour, tyre tech and general stability makes it the slightly safer overall experience.

Community Feedback

Price & Value

Neither of these is a screaming bargain, but they're not extortionate either. They sit in that honest middle ground where you pay real money and reasonably expect a real vehicle in return.

The Xiaomi 4 Pro typically costs more, but you're getting a noticeably larger battery, more refined braking, more sophisticated tyre tech and the weight of a massive ecosystem behind it. When you factor in range, reliability, parts availability and resale value, its higher tag makes a certain cold, boring kind of sense.

The SOFLOW SO4 Gen 3 undercuts it, but not dramatically. At that level, a battery this small starts to look a bit stingy. Where the SoFlow redeems itself is for heavier riders and law-obsessed markets: very few scooters at this price openly claim a comparable max load with this level of braking and lighting. If you're well below that load and just want range, you're subsidising a strength you may never use.

As a general commuter for an average-weight rider, the Xiaomi offers better long-term value. The SoFlow's value proposition is much more niche but legitimate if you actually need what it specialises in.

Service & Parts Availability

This one isn't even a contest.

For the Xiaomi 4 Pro, parts, third-party spares, tyres, brake bits, tutorials, and local workshops are everywhere. You break something, someone has done it before, filmed it, and listed the part on three different marketplaces. Firmware quirks, common issues, tricks - the community has already paved the way.

SOFLOW, as a brand, is established in central Europe but nowhere near Xiaomi levels. You can get parts and service, but it's more dependent on official channels or a few specialised shops. Community documentation and third-party upgrades are thinner. Add the fact that some riders report mixed experiences with customer service and you're clearly dealing with a more "niche" ecosystem.

If low-friction ownership and easy repairs matter to you, Xiaomi is the safer bet by a long margin.

Final Verdict - Which Should You Choose?

After enough kilometres that I stopped thinking about "testing" and just used them as transport, a pattern emerged. The Xiaomi 4 Pro is the scooter I forgot about - in the best way. It simply took me where I needed to go, day after day, without range nerves or weird behaviours. Its flaws - weight, no suspension - are shared with the SoFlow, but it compensates with more range, better tyre tech, and far better support if something does go wrong.

The SOFLOW SO4 Gen 3, by comparison, feels like a competent but slightly specialised tool. If you're a heavier rider, or you routinely carry a heavy backpack and really value that high load rating and dual mechanical discs, it makes a certain quiet sense. For a short, predictable commute in strictly regulated markets, it's a sensible choice that feels reassuringly stout, even if its battery looks shy in 2025.

So my advice is simple: if you're of average build and want a "buy it, ride it, forget it" commuter that will hold its own for several seasons, choose the Xiaomi 4 Pro. If you're at the upper end of the weight spectrum or you absolutely prioritise structural robustness and legal safety add-ons over range, then the SOFLOW SO4 Gen 3 can still be the right call - just go in with realistic expectations about how often you'll be hunting for a charger.

These metrics look purely at how efficiently each scooter converts weight, price, power, battery size and charging time into usable performance. Lower cost per Wh or per kilometre means you get more "electricity" or range for your money. Lower weight per Wh or per kilometre indicates a lighter machine for the same energy or distance. Wh per km reflects how hungry the scooter is - lower is more efficient. Power-to-speed and weight-to-power show how muscular the drive system is relative to its limits, while average charging speed tells you how quickly the battery refills in practice.

Based on the scoring, the XIAOMI 4 Pro is our overall winner. In the end, the Xiaomi 4 Pro simply feels like the more rounded companion: it rides further, feels more polished under your feet, and fades into the background of your life in that very satisfying "it just works" way. The SOFLOW SO4 Gen 3 has its own quiet strengths - especially if you're a heavier rider who values a stout frame and straightforward hardware - but it never quite shakes off the sense that you've compromised on range to get them. If I had to pick one to live with for a couple of years of boring, real-world commuting, I'd take the Xiaomi keys every time and let the SoFlow be the backup. It's not perfect, but it's the scooter that's easier to trust when you're already running five minutes late.

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.
