Fast Answer for Busy Riders ⚡ (TL;DR)
If you want the more complete, low-stress everyday scooter, the Segway E25E comes out on top: it feels more mature, better sorted, and easier to live with long term, even if its comfort and range are nothing to brag about. The SoFlow SO2 Zero only really makes sense if your rides are very short, very flat, and you absolutely prioritise low weight and German/Swiss road legality over everything else - including range and punch.
Pick the Segway if you want something you can just charge, unfold, and forget. Pick the SoFlow if your commute is just a few kilometres, you're often on trains, and you're willing to accept sharp compromises for portability and legal peace of mind.
If you want to understand where each scooter quietly wins - and where the marketing brochures are very optimistic - stay with me, because the details matter here.
Urban, lightweight commuters are spoiled for choice right now, and the Segway E25E and SoFlow SO2 Zero are prime examples of why the spec sheet never tells the whole story. On paper they look like cousins: compact, modestly powered, commuter-friendly scooters with similar weight and very sensible top speeds.
On the road, though, they have very different personalities. The Segway E25E is the polished city gadget that wants to be invisible in your life: unfold, glide to work, fold, forget. The SoFlow SO2 Zero is the legal-friendly featherweight that looks good on a brochure rack at a Swiss train station, but makes you plan your journeys with a calculator.
The Segway suits riders who want hassle-free reliability and a grown-up feel; the SoFlow suits short-hop minimalists who treat the scooter more like a powered briefcase than a vehicle. Let's dig in and see where each one actually earns its keep.
Who Are These For, and Why Compare Them?
Both scooters live in the compact-commuter world: city riders, students, and multi-modal commuters who need something light enough to carry, legal enough not to attract tickets, and simple enough to ride in office shoes.
The Segway E25E sits in the "premium mid-range" camp. It's clearly aimed at people who might otherwise buy a Xiaomi or NIU, but who want something that looks cleaner and feels more like a polished consumer device than a hobby project. Think bike lanes, smooth city streets, and short to medium hops from station to office.
The SoFlow SO2 Zero is the more aggressively "entry-level" machine: cheaper sticker price, smaller battery, and very clearly tuned to tick German and Swiss regulation boxes. It's meant to live in your hallway or under your desk and only leave a relatively small radius around your home or station.
They're competing for the same rider mentally: someone who wants a legal, light scooter that doesn't scare them. The question is which one compromises smarter given that brief - and which one you'll still be happy with after a few hundred kilometres.
Design & Build Quality
Pick both up and you immediately feel two design philosophies. The Segway E25E is that typical Segway blend of minimalist industrial design and "we've done this a lot" refinement. Cables are tucked away almost entirely inside the frame, the stem is a clean cylinder with the battery hidden within, and the deck is razor-thin and tidy. It really does feel like a rolling gadget, not a small scooter that escaped a rental fleet.
The SoFlow SO2 Zero is more straightforward: still aluminium, still reasonably solid, but less obsessively polished. You notice more visible hardware, more "scooter first, consumer electronics second" vibes. The paint and colour schemes are fun - the turquoise/green options give it a modern, youthful touch - but it doesn't quite hit the same premium note when you run your hands along the welds and joints.
In terms of build solidity, the Segway has that reassuring "rental-grade DNA": the stem feels stout, the folding joint clicks with confidence, and even small touches such as the grips and rubber deck covering feel like they'll survive years of sweaty commutes. The SoFlow frame itself is actually quite robust and impressively rattle-free for an entry scooter, but you start to notice the cost cutting in places like the tyres (not split rims), the ports, and the general feel of the electronics.
Ergonomically, taller riders will actually feel more at home on the SoFlow: the bar height is a bit friendlier if you're north of 1,80 m, whereas the Segway has a more "average height" sweet spot. But overall design cohesion and perceived quality clearly lean in favour of the Segway.
Ride Comfort & Handling
Comfort is where their different tyre choices come roaring to the front. The Segway E25E uses foam-filled solid tyres with a short-travel front spring. On smooth tarmac and bike lanes the ride is pleasantly firm and efficient - you roll quickly and the scooter feels eager. The front shock takes the sting out of small edges and expansion joints, so your wrists don't get murdered.
Then you hit cobbles or broken pavement and the romance ends quickly. Those dual-density tyres are better than hard plastic, but they're still essentially solid. After a few kilometres on rough, old-town streets your knees and ankles will be filing complaints. You can ride that terrain; you just won't particularly enjoy it for long stretches.
The SoFlow SO2 Zero goes the opposite way: no mechanical suspension at all, but proper pneumatic tyres. On typical city asphalt and regular bike paths, that means a noticeably softer, more forgiving feel. You get that subtle "float" that air tyres provide over small imperfections, and the scooter tracks nicely through corners with predictable grip.
But the lack of any shocks means the hits that do get through can be sharp. Big pothole, tram track at a nasty angle, stone edging - you feel it straight up your spine. On long sections of cobbles, you end up riding like a mountain biker: knees bent, actively absorbing impacts. Between the two, I'd rather be on the SoFlow for typical mixed city surfaces, and on the Segway for long, clean stretches of bike lane or shared paths.
Handling wise, the Segway feels a bit more "grown-up stable" at its higher cap: steering is calm, the chassis doesn't twitch, and those slightly larger foam tyres give you a solid planted feel in sweeping turns. The SoFlow is nimble and easy to flick around, especially at slower speeds and in tight city clutter, but you are always aware that you're on a light scooter with modest tyres and no suspension - it's agile rather than confidence-inspiring.
Performance
Neither of these is going to win traffic-light drag races against bigger commuters, but one of them feels more like a restrained adult, the other more like a slightly undercaffeinated intern.
The Segway E25E has a modest hub motor on paper, but the tuning is very Segway: smooth, linear, and just "enough" for flat-land commuting. It gets up to its legal-limit top speed in a controlled, progressive way. You won't be yanking your shoulders out of their sockets, yet you don't feel dangerously underpowered when you want to leap across a junction. On mild to moderate inclines it will still pull you up without drama, as long as you're not at the very top of the weight limit.
Once you point it at steeper gradients, its city-scooter nature shows - speed drops off, and heavier riders will find themselves adding some kicks. But it rarely feels like it's truly giving up; more like it's politely asking whether you really meant to go that way. The option of an external extra battery (and the associated bump in punch and speed, depending on region) also gives it a nice performance upgrade path if you outgrow it.
The SoFlow SO2 Zero has a motor with similar nominal power, but the overall experience is more conservative. From a standstill, acceleration is gentle - beginner-friendly, but if you're used to anything more powerful, it feels a bit lethargic. On flat ground it ambles up to its lower speed cap steadily enough, but never with enthusiasm. In cities where everyone else is capped similarly, that's fine; next to faster bikes and scooters, you feel slightly outgunned.
Hills are its Achilles' heel. Even modest gradients can turn the ride into a slow-motion struggle, especially if you're a heavier rider. I've seen it crawl on slopes where the E25E still makes a respectable effort. You can coax it along with kicks, but that somewhat defeats the purpose of an electric scooter.
Braking is interesting on both. The Segway's multi-system braking (electronic plus magnetic plus a "panic" foot brake) gives you a good level of modulation: squeeze the thumb brake and you get progressive stopping power without nasty surprises, and you always have that fender brake as a last resort. It's not sports-car sharp, but it feels balanced and confidence-building.
The SoFlow's combination of front electronic and rear drum looks great on a spec sheet, but the tuning can be abrupt. The electronic front brake tends to bite first, and if you're not ready - weight back, arms braced - it can feel like the scooter wants to nosedive. The rear drum is solid and low-maintenance, but the overall braking feel takes more adaptation time than on the Segway.
Battery & Range
This is where things get really lopsided, and where the SoFlow's compromises become hard to ignore.
The Segway E25E carries a modest-sized battery by modern standards, but it's at least in the same ballpark as other mid-range commuters. Manufacturer quotes are, as usual, optimistic. In the real world, riding like a normal human - mixed speeds, some stops, maybe a few gentle inclines - you're looking at a comfortable short-to-medium daily loop without having to start sweating about the battery percentage halfway through. For typical inner-city commutes, you can do both directions on one charge, or go one way and top up at work without worrying.
The SoFlow SO2 Zero is a very different story. The battery is tiny, and it behaves exactly like a tiny battery in a real city. Range claims might squeak into the low double digits on a perfectly flat, slow, feather-weight test rider. In everyday use, you regularly see the gauge drop far quicker than expected, and the scooter begins to lose vigour well before "empty". Many riders report effective, comfortable range in the single-digit kilometre zone - enough for a short dash from station to office and back, but not enough for spontaneous detours or mis-planning.
The psychological effect is important: on the Segway you mostly ride and occasionally glance at the battery. On the SoFlow you tend to ride the battery and occasionally glance at the scenery. If your commute is razor-short and predictable, that can be manageable. For anyone else, that creeping range anxiety becomes tiresome very quickly.
Both charge in roughly a work-half-day, thanks to their relatively small packs. The upside of these light batteries is you can genuinely arrive nearly flat, plug in under your desk, and leave with a full scooter. But only one of them gives you a range buffer big enough that you don't feel like you're planning a NASA mission to pop to the supermarket.
Portability & Practicality
Weight wise, they're near-identical - both around the mid-teens in kg - and both qualify as "I can carry this, but not forever." The difference is how that weight is distributed and how well the scooter behaves off the road.
On the Segway E25E, with the battery in the stem, you get a slightly top-heavy feel when carrying it. The upside is a thin, elegant deck; the downside is that when the scooter is on its kickstand, a slope or mild knock can send it toppling more readily than you'd like. The folding mechanism, however, is excellent: that foot-operated latch is quick, one of the easiest in the business, and feels well engineered. You can be off the scooter and walking into a train carriage in a couple of seconds without much fumbling.
The SoFlow SO2 Zero was built with "haul me up stairs" in mind, and it shows. The balance in the hand is slightly nicer, and the simple lever-fold system will be very familiar to anyone who has used budget commuters. It's straightforward and reasonably sturdy. Folded, the dimensions are compact enough to live in small car boots and next to your desk without drama. In that narrow sense - raw ease of lift and carry - the SoFlow is slightly more agreeable.
Daily practicality also includes maintenance. Here, the Segway quietly wins. Solid tyres mean zero puncture drama and no weekly pressure checks, and with most cables hidden, there's less to snag or corrode. Yes, you pay for that with harsher ride, but "always ready to go" is genuinely valuable when you just want transport, not a hobby.
The SoFlow's air tyres make the ride nicer but bring the usual urban lottery of punctures. On this model, tyre changes are notoriously annoying - no split rims, tight beads, lots of swearing. Add in reports of buggy app connectivity and the occasional controller issue, and the ownership experience starts to feel a bit more hands-on than many casual riders would like.
Safety
Both scooters take safety seriously, but they focus on different aspects.
The Segway E25E plays the "systems working quietly together" game. The multi-layer braking approach is forgiving and inspires confidence once you're used to it. Lighting is solid: a bright enough headlamp for urban use, plus lots of reflectors, and that under-deck ambient lighting which, despite the party vibes, actually makes you more visible from the side. The chassis feels composed at its top speed, and the thumb controls are intuitive with good tactile feedback.
On the SoFlow SO2 Zero, legal compliance drives the feature list. The integrated front and rear lights are proper road-approved units, bright enough to actually show you where you're going in darker months. The built-in indicators are an excellent touch - signalling without taking a hand off the bar is no small win in busy traffic. The wider deck and those pneumatic tyres give a reassuring footprint on the road, especially in the wet, where solids can get skittish.
But the braking dynamics are less friendly: that grabby front electronic brake can catch new riders out, and the lack of suspension means emergency stops on rough surfaces can be quite dramatic. On the Segway, hard braking on poor tarmac still feels controlled; on the SoFlow you really need to shift weight and brace properly to avoid a forward pitch.
In short: the SoFlow wins on "visibility to others" thanks to its road-legal light package and indicators; the Segway wins on "how predictable it feels when you actually have to react fast".

Price & Value
On sticker price alone, the SoFlow SO2 Zero looks like a bargain: you get a legal, lightweight scooter for noticeably less money than the Segway E25E. For riders in tightly regulated markets, that's not trivial - avoiding fines and insurance headaches has a value.
But value isn't just how low you can get in at; it's how much scooter you get for every euro you keep pouring in. The SoFlow's extremely small battery and modest performance mean you hit its limits quickly. If your usage ever grows beyond those few short kilometres, the only upgrade path is "buy another scooter". Its tyres and occasionally flaky electronics can also mean more hassle time than you might like.
The Segway E25E costs noticeably more upfront, and on paper you might look at the motor and range figures and raise an eyebrow. Yet in practice, you're paying for refinement, lower maintenance, better parts availability, stronger brand and service backing, and an upgrade option via the external battery. Over a couple of years of regular commuting, that "it just works" factor quietly pays you back in fewer headaches and fewer "why did I cheap out?" moments.
If your budget ceiling is absolute and your rides are tiny, the SoFlow can be defended as decent value. For most everyday urban riders, the Segway makes more financial sense over the life of the scooter.
Service & Parts Availability
Segway-Ninebot is the Toyota of scooters: big, boringly competent, and everywhere. For the Segway E25E, that means a wide dealer network, plenty of third-party repair guides, and a healthy supply of official and unofficial spares. Need a new fender, a controller, or a display a couple of years in? Chances are you can find it easily online within the EU. Community knowledge is vast, which matters once the warranty has long expired.
SoFlow is much more regional. In the DACH area, you do get better-than-no-name support and at least a real company standing behind the warranty, which is more than can be said for many marketplace imports. But availability of parts and turnaround time can vary, and outside their home turf things get thinner. The app issues that have lingered for some users also suggest that software support isn't always as fast or polished as it should be.
From a purely ownership-stress perspective, the Segway is the safer bet if you plan to ride the scooter hard and long, and expect to keep it going past the honeymoon period.

Final Verdict - Which Should You Choose?
If I had to pick one of these to live with daily - not just to test for a weekend - I'd take the Segway E25E without hesitation. It's not exciting, but it's coherent. It looks and feels like a finished product, not a compromise exercise. The range is enough for typical city life, the braking is predictable, the folding and carrying experience is sorted, and the brand backing and spares ecosystem mean you're unlikely to be left stranded by a minor failure.
The SoFlow SO2 Zero has its place, but it's a narrow one. If your city is pancake-flat, your commute is just a couple of kilometres each way, and you're in a country where legal approval is a minefield, it can be a sensible, very portable solution. You get proper lights, indicators, and a frame that feels sturdier than the spec sheet might suggest. But once you push beyond those niche conditions, its tiny battery, soft performance, and niggly maintenance realities catch up quickly.
In real everyday use, the Segway simply feels more trustworthy, more rounded, and less likely to annoy you. The SoFlow can be good value if you understand - and truly accept - its hard limits. For most riders, though, the E25E is the scooter that better balances compromise with competence.
