Fast Answer for Busy Riders ⚡ (TL;DR)
The HIBOY KS4 Pro is the stronger all-rounder: it feels more sorted as a daily commuter, offers noticeably better real-world range, stronger brakes, and tyres you'll never have to patch on the pavement. If your priority is straightforward, stand-up city commuting with minimal maintenance headaches, the KS4 Pro is the safer bet despite its flaws.
The ISCOOTER F2, on the other hand, is a quirky little utility machine: seated riding, basket, very approachable handling - great if comfort and carrying groceries trump everything else and you're mostly on flatter ground. Just be aware you're buying into short range, modest power and a very "budget" feel.
If you want a commuter that behaves like a tool rather than a toy, keep reading - the devil, as always, is in the details.
Electric scooters in this price bracket all promise the same thing: car-killing convenience for the cost of a long weekend away. The ISCOOTER F2 and HIBOY KS4 Pro both go after that promise, but with very different personalities - one leans into seated utility, the other into fuss-free commuting.
I've spent enough kilometres on both to know where the spec sheets flatter them and where reality cuts in. On paper they look close; on the road they're really not targeting the same rider. One wants to be your rolling shopping trolley and sofa, the other wants to be the forget-about-it city tool you fold under your desk.
If you're torn between a seated, basket-equipped "mini moped" and a more classic stand-up scooter with solid tyres and an app, read on - the choice says more about how you actually live than how fast you want to go.
Who Are These For, and Why Compare Them?
Price-wise, they live in the lower mid-range: not toy-grade cheap, but still solidly budget. Both promise "proper transport" rather than just last-mile fun, and both rely on a motor in the same ballpark, similar claimed speeds, and very similar overall weight.
The ISCOOTER F2 is aimed at people who don't really want to stand: older riders, mobility-limited users, students hauling stuff, anyone who likes the idea of a small, sit-down runabout. Think micro-shopping cart with a motor.
The HIBOY KS4 Pro aims straight at the urban commuter: office workers, students, first-time buyers who just want something that works every morning and doesn't ask for much mechanical affection. It's more of a classic scooter silhouette with some "grown-up" touches.
They clash because, for roughly the same outlay, you have to choose: seated comfort and utility with obvious compromises, or a firmer, more polished commuter that sacrifices the seat and basket.
Design & Build Quality
Pick up the F2 and it feels... honest. Chunky aluminium frame, wide deck, visible welds that say "factory, not sculpture". The matte finish hides abuse, but the whole thing looks more functional than refined. With the seat post and basket mounted, it starts edging towards budget e-moped vibes rather than sleek scooter.
The folding stem on the F2 is serviceable but not exactly satisfying. Add the seat into the equation and folding becomes a small ritual: seat down or off, then stem, then figuring out how to grab the whole contraption without barking your shins. It's fine for a car boot; less charming in a crowded tram.
The KS4 Pro by contrast feels tighter out of the box. The frame isn't exotic, but the finishing is more consistent, cables are better tucked away, and the folding latch snaps shut with more confidence. The deck rubber feels higher quality, and the centrally mounted dashboard actually looks designed rather than just "fitted".
Neither scooter screams premium when you really start prodding plastics and tolerances, but the KS4 Pro gives the impression of a product that's been iterated a few times. The F2 feels more like a clever idea executed to a price.
Ride Comfort & Handling
On comfort, the F2 has an unfair advantage: you're sitting down. Between the cushioned saddle, the spring under it and the fat, air-filled tyres, the first few kilometres feel almost comically plush for the money. Rattle down old pavement and most of the chaos disappears into the tyres and seat. Your legs and back barely clock the impacts - your backside does the work.
Handling on the F2 is very relaxed. The low centre of gravity from the seated position makes it incredibly unintimidating, almost bicycle-like. The wide deck and 10-inch pneumatics give stable steering, but you're not exactly carving corners; quick weight shifts are slower when you're anchored to a saddle. Think calm, not playful.
The KS4 Pro goes the opposite route: stand-up stance, solid tyres with a rear shock. On fresh tarmac, it glides nicely. As soon as the surface gets patchy, the honeycomb tyres remind you why air is still popular - you feel the texture of the road through your feet and hands. The rear shock takes the sting out of big hits, but it's not magically turning cobbles into butter.
Where the KS4 Pro redeems itself is control. Standing, you can use your knees as suspension, shift weight aggressively, and really lean into turns. The chassis feels composed at its top speed, and once you learn to ride it "athletically", it's more engaging than the F2. Over longer, bumpy stretches, though, the F2 keeps your body less tired; the KS4 Pro keeps your wrists more awake.
Performance
Both scooters claim similar motor power on paper and very similar top speeds, and in practice they sit in the same performance class. The difference is how they deliver it - and what you're doing with your body while it happens.
On the F2, acceleration from standstill is adequate rather than exciting. It pulls you up to its cruising speed without drama; seated, that speed feels faster than it is. Off the line, you won't embarrass yourself at a traffic light, but if you're heavier or on an incline you'll feel the motor working hard. On steep hills, the word is "patient", not "punchy".
On the KS4 Pro, the throttle has more intent. It surges off the line with a confidence missing from cheaper 350 W commuters. You're not snapping your neck, but you surge past rental scooters and most bikes without trying. The upper end of the speed range feels stable enough to actually use for sustained stretches, whereas on the F2, sitting at top speed for long periods feels a bit like asking too much of a budget frame and small drum brakes.
Braking mirrors that story. The F2's dual drums are low-maintenance and reasonably progressive, but feel a bit wooden when you really need to shed speed. The KS4 Pro's rear disc combined with electronic front braking bites harder and gives more feedback at the lever. In emergency stops, the Hiboy inspires more confidence; on the F2 I instinctively leave more margin.
Battery & Range
This is where the spec sheets quietly stop smiling at the F2. Its battery is on the small side; ridden at full tilt, you burn through it noticeably quickly. On a brisk commute using the top mode, you're looking at a distance that's fine for short hops, but not generous. Two modest return trips and you're hunting for a socket.
The F2's voltage sag is also more obvious: hammer the throttle towards the end of the charge and you can feel the scooter losing some of its initial pep. It still moves, but the "fresh battery" feeling doesn't last long if you ride aggressively.
The KS4 Pro carries a much healthier energy reserve. In real life, that translates into being able to commute a decent distance, stop at the shop on the way home, and still have enough left without nervously counting bars. Even at higher speeds and with some hills thrown in, you get a comfortable buffer. Eco riding stretches it further if you're patient.
Charging times are similar on paper, but because the Hiboy's pack is larger, it feels like you get more kilometres per plug-in session. With the F2 you plan around the charger more; with the KS4 Pro you can afford to forget about it for a day or two.
Portability & Practicality
Both scooters weigh in the same ballpark. Lift either by the stem and your biceps get a reminder that "portable" is a relative concept. Up one or two flights of stairs? Manageable. Daily fifth-floor walk-up? That's a fitness programme, not a commute.
The F2's practical trump card is obvious: seat and basket included. Being able to dump a full grocery bag into a basket and trundle home sitting down is genuinely liberating at this price. It changes the way you use the scooter: quick shop runs, parcels, backpacks - all the annoying short car trips suddenly make sense on two wheels.
The cost is bulk. With the seat and basket installed, the footprint is awkward on public transport, and folding becomes more of a puzzle. The folded package doesn't tuck under office desks as easily, and manoeuvring it through tight hallways takes more care.
The KS4 Pro folds into a slimmer, more conventional shape. Stem hooks to the rear fender, easy to grab in the middle and carry like a slightly overweight briefcase. Sliding it under a desk or into a boot is effortless. For multi-modal commuting - train plus scooter, bus plus scooter - the Hiboy is simply less of a faff. You do, however, need to wear a backpack or shoulder bag for your shopping; there's no cargo magic here.
Safety
On the F2, safety is mostly about stability and predictability. The wide deck, seated stance and big air tyres give beginner-friendly composure. Even riders with poor balance feel secure. Drum brakes are enclosed and consistent in the wet, and the lights are just about good enough to be seen, though for unlit paths I'd absolutely add an aftermarket headlamp. The low centre of gravity also helps in panic stops - you're less likely to pitch over the bars.
Where the F2 gets shakier is at its maximum speed on rougher surfaces. The chassis can flex a bit, and because the brakes aren't especially sharp, you tend to leave longer stopping distances. It's "safe enough" if you ride within its envelope; push harder and you feel you're asking more than the design really had in mind.
The KS4 Pro feels like it was designed from the outset as a commuter expected to mix with traffic. The braking package is stronger and more controllable, the lighting package is genuinely better - especially the side visibility, which matters far more than most people think - and the larger wheels with solid tyres remove the risk of a sudden flat at speed. On wet roads, that alone is a big safety win.
The trade-off is grip and vibration: solid rubber doesn't bite into sketchy surfaces the way good pneumatics do, and you need to respect painted lines and cobbles in the rain. But overall, at the same speeds, I simply feel more in control on the KS4 Pro, particularly when I have to slam on the brakes for a car door that appears out of nowhere.

Price & Value
On the sticker, the F2 undercuts the Hiboy noticeably. For that saving you get a seat, a basket, air tyres and a reasonably strong motor. If you're measuring value in "features per euro", the F2 looks like a bargain bin miracle. For low-speed neighbourhood errands on flat ground, it's hard to argue with the amount of scooter you get.
The KS4 Pro costs more but also feels more like a coherent commuter product. Bigger battery, better lighting and brakes, app integration, suspension, no-flat tyres - none of these are glamorous on their own, but together they make a scooter you can lean on daily without constantly fiddling with it or planning your routes around hills and sockets.
Long-term, the Hiboy is likely to feel like the "cheaper" choice if you actually commute every day: fewer puncture dramas, fewer range-related compromises, and a chassis that's more comfortable running at its limits. The F2 makes sense if your use-case is gentle and you really will use the seat and basket every other day; otherwise, the savings start to look less convincing on the road than on paper.
Service & Parts Availability
Both brands live mostly online, both ship parts, and both have a mixed but generally acceptable reputation for support. You're not getting a dealer down the street who'll wrench on it for you, but you're not abandoned either.
ISCOOTER tends to use fairly generic components, which is a double-edged sword: it makes finding third-party replacements easier if you're handy, but also means assembly and diagnosis sometimes feel a bit DIY. Community reports of responsive email support and shipped-out spares are encouraging, but you'll want a basic toolkit and some patience.
Hiboy, being everywhere, arguably has the edge in sheer volume of community knowledge and spare parts floating around Europe. Need a KS4 Pro brake disc or fender? Chances are someone on a forum has done the job already and can point you to the right bit. Their support gets decent marks too, but again, expect to be your own mechanic for anything beyond simple issues.

Final Verdict - Which Should You Choose?
If you strip away the marketing and look at how these scooters actually behave day in, day out, the HIBOY KS4 Pro comes out as the more rounded commuter. It brakes harder, goes further, copes with hills better, shrugs off punctures entirely, and folds into a more commuter-friendly package. It feels more comfortable living at the edge of its performance envelope, whereas the F2 feels slightly out of its depth when asked for repeated full-speed, full-range duty.
That doesn't make the ISCOOTER F2 a bad scooter; it makes it a specialised one. If your life is mostly short, flat trips, you dislike standing, and you'll genuinely use the basket all the time, the F2 will feel like a cheat code for everyday errands. It's approachable, forgiving, and very easy to love within its comfort zone.
For everyone else with a typical city commute, the KS4 Pro is the safer recommendation. It's not perfect - no scooter at this price is - but it behaves more like a transport tool than a toy and demands fewer compromises. If you want to gamble on comfort and cargo over range and robustness, pick the F2; if you just want something that gets you to work and back with minimal drama, the Hiboy is the one I'd live with.
