Fast Answer for Busy Riders ⚡ (TL;DR)
The Acer ES Series 5 is the overall winner here: it goes vastly further on a charge, feels more mature as a commuter tool, and inspires more long-term confidence, even if it isn't exactly thrilling. The Hiboy S2 SE counters with more speed for the money and a lower entry price, but you pay for that upfront saving with noticeably shorter range and a more budget-feeling ride. Choose the Hiboy if your commute is short, your budget is tight, and you mainly want something quick and disposable-ish for flat city hops. Choose the Acer if you actually rely on your scooter as transport and don't want to be hunting for a socket every other day.
If you care about turning your daily commute into a calm, predictable routine rather than a range-anxiety mini-game, keep reading - the details matter a lot in this matchup.
Electric scooters have matured enough that we're no longer just choosing between "toy" and "death machine". The Acer ES Series 5 and Hiboy S2 SE both sit in that crowded lower-mid commuter class: single front motor, sensible top speeds, app connectivity, and just enough comfort to keep your knees from filing a complaint after a week.
I've put real kilometres on both: the Acer as a "forget about it and just ride" long-range mule, the Hiboy as the classic cheap-and-cheerful campus commuter. On paper they overlap heavily; in practice they feel like very different answers to the same question: "How little scooter can I get away with for daily use?" The interesting part is where each one quietly falls apart - and where, unexpectedly, they don't.
If you're torn between spending more once or spending less now, this comparison should make the choice a lot clearer.
Who Are These For, and Why Compare Them?
Both scooters live in the "sensible commuter" category: single front hub motors, legal-ish top speeds for Europe, no insane acceleration, and enough tech features to look modern without being a science project.
The Acer ES Series 5 aims at the everyday urban commuter who actually racks up distance: think office worker doing a decent daily round trip, plus errands, and not wanting to charge every night. It's for people who treat a scooter more like a small vehicle than a gadget.
The Hiboy S2 SE is squarely aimed at budget riders: students, first-timers, or anyone whose commute is short and flat and who cares more about purchase price and zippy feel than about longevity or all-day range. It's the "my first real scooter" archetype, with a bit of extra spice on top speed.
They compete because they share the same fundamental formula - front motor, medium wheels, app, lights - and because a lot of people find themselves deciding: spend roughly two-thirds more on the Acer for endurance and polish, or pocket the savings with the Hiboy and accept its compromises?
Design & Build Quality
Visually, both scooters tick the modern commuter boxes: dark frames, integrated display, front stem light, nothing too loud. But living with them reveals very different build philosophies.
The Acer is classic big-brand consumer tech translated into a scooter. Aluminium frame, mostly internal cabling, and a cockpit that looks clean rather than cobbled together. Fold the stem and you get a reassuring clunk; there's minimal play at the hinge, and the whole structure feels like it's been through a few rounds of CAD stress analysis instead of just copied from the last guy.
The Hiboy's Q235 steel frame feels tougher in a "crowbar" sort of way - dense, sturdy, and not particularly refined. It doesn't creak, but it also doesn't have that tight, squeak-free assembly you get from better-finished models. Cable routing is okay but visibly more budget; nothing tragic, just less polished. It looks like transport, not a tech product - which some will actually like, to be fair.
Decks on both are sensibly sized, with grippy surfaces and room for a sideways stance. The Acer's rubberised pattern feels a bit more premium underfoot; the Hiboy's anti-slip coating is grippy but more utilitarian. Fender design is one of the Hiboy's nicer surprises: the widened rear fender does a better job of keeping road spray off your back than many scooters at twice the price.
Overall, the Acer feels like a mid-range commuter from a serious manufacturer; the Hiboy feels like a well-sorted budget scooter that's been iterated rather than reinvented. If you're picky about fit and finish, the Acer is ahead - not dramatically, but noticeably.
Ride Comfort & Handling
This is where the two start to diverge quite a bit in character.
The Acer pairs big foam-filled tyres with a rear suspension unit. On smooth asphalt, it's fine - almost plush for a solid-tyre machine. Hit typical city imperfections (expansion joints, patched tarmac, the occasional lazy manhole cover) and the rear shock earns its keep, smoothing out hits that would otherwise slap your spine. You still feel the texture of the road - solid tyres don't do miracles - but the nastiest impacts are rounded off. Steering feels stable rather than lively; it prefers straight, predictable paths to tight, playful slaloms.
The Hiboy relies entirely on its tyre setup for comfort: solid front, pneumatic rear. Think of it as suspension from the ankles down on the back wheel, and "hope for the best" up front. With most of your weight over that air-filled rear, your feet and knees fare better than you'd expect. But your hands pay the price: sharp edges, cracked pavements and brickwork transmit clearly into the bars via that solid front tyre. After a few kilometres of rougher surfaces, you start unconsciously lightening your grip and shifting weight back before every bump - workable, but you're doing more of the suspension work yourself.
In handling, both benefit from moving up to larger wheels compared with old 8,5-inch toys. The Acer feels a bit more planted, especially at its limited top speed; the longer wheelbase and rear suspension give it a composed, almost slightly dull stability. The Hiboy, with its slightly sportier top end and firmer front, feels more agile and eager to dart around obstacles - fun, but more fatiguing on bad surfaces.
If your daily route is mostly smooth tarmac, the Hiboy's comfort is acceptable and its agility can be enjoyable. If your city specialises in broken pavement and lazy utility repairs, the Acer's rear suspension and generally calmer chassis make for a less tiring ride.
Performance
On paper both scooters use a similar-rated front hub motor. On the road, they've clearly been tuned for different priorities.
The Acer's motor is the model of restraint. It pulls away smoothly, with a gentle ramp-up that beginners will appreciate. In the highest mode it gets up to its legal-friendly ceiling without drama, then just sits there, humming along. It feels composed and predictable, but you never mistake it for sporty. On moderate inclines, it keeps going but you feel it dig in; steeper hills definitely ask you to contribute with a few kicks, especially if you're on the heavier side.
The Hiboy, by contrast, has that familiar budget-scooter eagerness. It spools up faster, nudging you forward with more urgency from a standstill and pushing on to a higher top speed that feels properly brisk for city bike lanes. It's still not going to rip your arms off, but if you like to nip ahead of cyclists at traffic lights, the Hiboy is the one that feels more willing. Of course, at that higher cruising speed, small imperfections in the road and the slightly firmer front end become more noticeable.
On hills, both are honest about being mid-power commuters. Neither loves serious gradients. The Hiboy's slightly sportier tune helps it feel a touch more determined at first, but once both are working near their limit, they settle into the same slow-and-steady grind. Think "walk-speed crawl up the steepest residential streets" rather than heroic climbing. If you live somewhere truly hilly, you're shopping in the wrong performance class altogether.
Braking is solid on both, with different flavours. The Acer's combination of rear disc and front electronic brake gives a familiar lever feel and good control, with the added stability of not relying on a front mechanical brake. The Hiboy uses an electronic front brake plus a rear drum: I'm a fan of drums for commuters - they're sealed, consistent in the wet, and don't go out of adjustment as quickly. Stopping power on the Hiboy is entirely reasonable for its weight and speed, but the modulation feels slightly less refined than on the better-tuned setups from premium brands.
Battery & Range
This is the big, defining difference, and frankly the reason many riders will lean Acer almost by default.
The Acer carries a battery that's closer to what you expect in upper mid-range commuters: a proper chunky pack that, in the real world, delivers several tens of kilometres even when you ride fast, deal with traffic stops, and weigh something closer to an actual adult than the manufacturer's test rider. Manufacturer claims are, as always, optimistic, but even knocking a third off still leaves you with genuinely useful day-to-day distance. It's the kind of scooter you can ride hard for a full workday's commuting and errands and still have a buffer.
The Hiboy's pack, by comparison, belongs firmly in the "short-hop" category. The advertised figures are only achievable if you float around in eco modes at bicycle speeds with a light rider. Use it as intended - top mode, real-world stop-and-go, mixed terrain - and you're realistically in that mid-teens of kilometres window before the gauge starts to look worryingly low. That's fine for many commutes, but you need to be honest about your distances and whether you can charge at your destination.
Charging times mirror this philosophy. The Acer takes a full night to refill that large pack. You plug it in, forget about it, and in the morning you're good for another couple of days of average use. The Hiboy, with its smaller battery, comes back to full far quicker - realistically within half a working day - which does help mitigate the shorter range if you can charge at work or school.
In terms of range anxiety, the difference is stark. On the Acer, you simply stop worrying about it unless you're planning something silly. On the Hiboy, you're very aware of the gauge if you stack multiple trips in one day. If you want your scooter to replace more than just one simple commute, the Acer is the safer bet.
Portability & Practicality
Both scooters land in the "carryable, but not exactly featherweights" category. The Hiboy is the lighter of the two by a modest margin, but not enough to transform the experience; neither is something you're joyfully running up three floors with every day.
The Acer's extra mass comes mostly from that big battery and the rear suspension hardware. You feel it when you lift it - especially if you try one-handing it by the stem. For the occasional staircase, train gap, or car boot lift, it's fine; for daily long carries, it becomes a chore. Folded, it's reasonably compact length-wise, but the overall package still reads as "substantial scooter" rather than "throw-it-anywhere stick".
The Hiboy, being slightly leaner, is kinder to your back but still not a true lightweight. Where it wins is the folding ergonomics: the latch is quick, positive, and the folded height is noticeably lower. Sliding it under a desk, into a corner of a small flat, or under a café table is simply easier. If you're mixing scooter and public transport regularly, the Hiboy's form factor is less intrusive.
Both offer app integration for locking and tweaking settings. Acer's ecosystem feels more like something a PC brand would ship: functional, slightly corporate, with features like cruise control and motor lock presented in a straightforward way. Hiboy's app leans more towards the "budget gadget" vibe but still gives you the important toggles - acceleration curve, regen strength, basic diagnostics. Both apps can be a bit temperamental on Bluetooth handshake; this is sadly par for the course across much of the industry.
Weather-wise, they're both sensible, splash-resistant commuters: drizzle and damp roads, yes; torrential downpours and deep puddles, no. The Acer's slightly better-anchored cabling and brand-level QC give me marginally more confidence in long-term wet survival, but you still shouldn't treat either like a boat.
Safety
Safety on these two is more about execution than features - they broadly have similar tools, but some are implemented more thoughtfully.
The Acer scores well with its dual braking approach and generally stable geometry. The rear disc plus front electronic braking gives confident stopping without the twitchiness you sometimes get from over-eager front mechanical setups. The big foam tyres and slightly longer chassis contribute to a secure, "on rails" feeling at its modest top speed, and the deck grip is generous. Lighting is decent: a stem-mounted front light, rear light with brake indication, side reflectors, and, in some markets, integrated indicators - which is genuinely handy in traffic if your region gets that spec.
The Hiboy's brake mix - electronic front, rear drum - is also sound. I particularly like drums for low-maintenance safety, and here it does exactly what a commuter needs: predictable stops, even after city muck and rain. Lighting is actually one of the Hiboy's strongest points: the bright headlight, proper rear brake light, and that ring of side illumination give you a nicely visible presence at night. Some riders grumble about the headlight angle not illuminating the space right in front of the wheel enough, which is fair - but still, in this price class, visibility is above average.
In terms of stability, the Acer has the edge purely because it never dares to go as fast. Its front-heavy configuration with solid tyres doesn't invite heroics, and at its limited ceiling the chassis feels composed. The Hiboy is happy to push into speeds where you actually need to pay attention; combine that with a solid front tyre and budget-class tolerances, and mistakes on rough surfaces are punished more sharply. It's safe enough, but it demands a bit more rider responsibility.

Price & Value
This is the uncomfortable section for the Hiboy - and the one that makes the Acer look more sensible than "exciting".
The Hiboy comes in dramatically cheaper. For less than many people spend on a monthly rail card and a couple of dinners out, you get a scooter that will do real-world city speeds, fold up neatly, and offer app features that used to be reserved for pricier models. On a tight budget, it's hard not to see the appeal: it's quick enough, feels reasonably solid, and if it gets nicked outside a bar, you're upset, not devastated.
The Acer, on the other hand, asks a significantly higher price, but you're clearly paying for battery and a more thought-through commuting experience. That huge jump in usable range, the nicer build, the rear suspension, and the backing of a major tech brand all add up. If you treat your scooter as daily transport rather than a toy, the extra investment starts to make financial sense: fewer alternative transport costs, and you're not immediately hunting for an upgrade after one season.
Looked at in pure "performance per euro" terms - speed and motor feel only - the Hiboy punches above its weight. Once you factor in range, refinement, and daily comfort, the Acer quietly claws back the value argument. It isn't a bargain in the thrilling sense, but it is, annoyingly, the more rational purchase for most commuters.
Service & Parts Availability
Acer comes with the weight of a global electronics brand. That means established distribution, formal service partners in many European countries, and the comfortable feeling that the company isn't disappearing next week. You're more likely to deal with a bricks-and-mortar retailer or national distributor for warranty issues, which tends to be less of a lottery than emailing a generic contact form and hoping.
Hiboy, for a budget-focused brand, does better than many of its peers. Parts like tyres, controllers and fenders are relatively easy to source, and the community has built up a decent knowledge base. Support is reported as "better than expected" more often than "hopeless", which in this price tier is almost a compliment. Still, you are fundamentally dealing with a volume-oriented brand whose margin on each unit is slim; don't expect premium-brand hand-holding.
For DIY-inclined riders, both are serviceable. The Acer's neater integration means a bit more care when diving into internals, but also more consistent component quality. The Hiboy's simplicity and steel frame make it approachable for home fixes, though you do feel the occasional rough edge in design when you get under the skin.

Final Verdict - Which Should You Choose?
If I strip it down to the way these two actually feel in daily use, the Acer ES Series 5 comes out as the more complete, grown-up scooter. It isn't thrilling, and it certainly isn't light, but it does the basic commuter job with fewer compromises: serious battery capacity, calmer chassis, rear suspension, and a build that feels like it'll survive several years of abuse rather than just a couple of semesters.
The Hiboy S2 SE, by contrast, is the classic budget overachiever: faster on top for the price, lively enough to be fun in short bursts, and cheap enough that your wallet doesn't flinch. But you're trading away range, comfort on rougher surfaces, and a bit of long-term polish to get that sticker price down, and you really feel those trade-offs once the novelty wears off.
If your riding is mostly short, flat, under-10-kilometre urban runs and your budget is genuinely tight, the Hiboy remains a defensible, pragmatic choice - just go in with realistic expectations about range and front-end comfort. For everyone else who wants a scooter they can rely on day in, day out, without constantly planning around battery level or road quality, the Acer ES Series 5 is the more sensible and ultimately more satisfying partner, even if it never once tries to impress you with drama.
