Fast Answer for Busy Riders ⚡ (TL;DR)
The Acer ES Series 4 Select comes out as the more complete everyday commuter: it rides softer, feels safer in sketchy city conditions, and offers a better mix of comfort, features, and range for the money. The Razor C45 fights back with slightly stronger punch and a higher top speed, but it's rougher, less refined, and asks quite a lot at the checkout for what it delivers. Choose the Razor if you really value that bigger front wheel, like a sturdier "steel tank" feel, and mostly ride on smooth tarmac with short-ish commutes. Everyone else will generally be happier - and less battered - on the Acer.
If you care about arriving relaxed rather than rattled, read on - the differences get more interesting the deeper you go.
Electric scooters have entered that awkward "everywhere but not all equal" phase. Walk through any European city and you'll see office workers on dull rental sticks, students on overpowered monsters, and everything in between. Sitting right in the middle of this chaos are two familiar tech names trying to win your commute: Acer with its ES Series 4 Select, and Razor with the C45.
On paper, they're natural rivals: both aimed at adults, both from brands you actually recognise, both promising enough power to ditch the bus without terrifying your insurance company. The Acer leans into comfort, modern safety tech and a very "I have a real job" aesthetic. The Razor counters with more shove, a bigger front wheel and that reassuring steel heft that whispers "you can kick me, I'll survive".
If you're torn between these two, you're in the right place. I've put real kilometres on both, over nice bike lanes, broken pavements and the usual mix of rain, potholes and questionable drivers. The differences aren't subtle - and they matter a lot once the honeymoon period wears off.
Who Are These For, and Why Compare Them?
Both scooters sit in the mid-range "serious commuter, not a toy" bracket. They're for adults who want something they can actually rely on Monday to Friday, not just for Sunday park laps. Think office workers, uni students with a decent commute, and anyone tired of sardine-mode on public transport.
The Acer ES Series 4 Select is clearly tuned for the everyday urban rider who values comfort, safety gadgets and predictability more than bragging rights. It feels like a piece of consumer electronics that happens to roll - in a good way.
The Razor C45 aims at the same rider, but with a different philosophy: bigger front wheel, steel frame, a bit more motor and speed, a bit less polish where your joints live. It tries to be the rugged workhorse you park in a bike rack and forget.
Same general mission, very different executions - which is exactly why they're worth comparing head-to-head.
Design & Build Quality
Pick up the Acer and it feels like what you'd expect from a modern tech brand: aluminium frame, clean lines, cables neatly routed inside the stem, everything fitting together like it was actually designed rather than sourced from the "random parts" bin. The matte black finish looks understated and professional - no gamer-RGB nonsense, just a scooter that won't embarrass you in front of the office.
The Razor C45, in contrast, feels more old-school industrial. The steel frame is solid and confidence-inspiring, but also a bit... blunt. Welds are functional rather than pretty, the design is more "urban utility" than "industrial design award". It looks tough, and to be fair, it is. But you're reminded of that toughness every time you have to lift it or hit a sharp bump.
In the hand, the Acer's controls feel more thought-through: grips, indicator buttons, display, everything is laid out like someone actually test-rode the prototype before signing it off. On the Razor, the basics work, but it's more of a "that'll do" cockpit - especially the thumb throttle, which is fine but not exactly confidence-inspiring when you're bouncing over imperfections at higher speed.
Both scooters avoid the dreaded budget-scooter stem wobble reasonably well when new; the Acer feels tighter for longer, whereas the Razor's folding area and rear fender are more prone to developing rattles under abuse. Steel survives, sure - it just doesn't always stay quiet about it.
Ride Comfort & Handling
This is where the Acer quietly walks away with the "actual daily life" trophy. Front fork suspension plus reasonably large, air-filled tyres front and rear mean the ES Series 4 Select takes the edge off bad infrastructure. Ride five kilometres over patched-up asphalt and random paving stones and you arrive with hands and knees that aren't filing a formal complaint. It's not a magic carpet, but it's solidly on the "comfortable commuter" side of the spectrum.
The Razor's comfort story is split in half - literally. That big pneumatic front wheel is genuinely excellent: it gobbles up cracks and small potholes, keeps the front end calm and planted, and makes the scooter feel reassuringly stable in a straight line. Then the rear end arrives, with its solid tyre, no suspension and rigid steel frame. On smooth bike lanes, you're fine. On rougher surfaces, your feet and knees get a constant reminder that Razor chose "no rear flats ever" over ride comfort.
Handling-wise, both are rear-wheel drive and reasonably predictable. The Acer feels lighter and a bit more nimble in tight city manoeuvres, helped by its lower centre of gravity and more compliant front end. The Razor is calmer at higher speeds in a straight line thanks to that big front wheel, but less forgiving when you hit expansion joints or cobbles mid-corner - the rear will happily broadcast every imperfection through your legs.
If your city is mostly smooth tarmac, both are rideable. If your city planners hate you and your joints, the Acer is simply kinder to your body.
Performance
Neither of these is a "hold my beer" scooter, and that's fine - they're commuters. The Razor C45 does feel a touch stronger when you pin the throttle: its motor pulls a bit more eagerly off the line and nudges you up to its higher top speed with more enthusiasm. In Sport mode you're into "I should probably be paying attention now" territory, and that front wheel really earns its keep here, giving you a planted front end when the scenery starts to blur.
The Acer's motor is slightly more modest, but still a clear step up from rental-level scooters. Acceleration is smooth and controlled rather than dramatic, which is exactly what you want when you're weaving around pedestrians and parked cars. It happily keeps pace with city cycling traffic and overtakes the casual riders without drama. The tuning feels grown-up: enough torque to feel safe, not enough to catch you out on damp surfaces.
On hills, both are firmly in "single-motor commuter" land. Gentle urban inclines are fine, short steeper ramps are handled with a sigh, and long, brutal climbs will slow them both. The Razor's motor has a slight advantage on milder hills, but neither is a solution for San Francisco-style topography unless you enjoy watching your speed bleed away.
Braking is where priorities diverge. The Acer's combination of front disc and rear electronic ABS feels much more confidence-inspiring, especially in the wet. You can brake hard without the rear stepping out or the front trying to catapult you. Modulation is good; you feel in control rather than gambling. The Razor's rear disc plus regen setup works, but at its top speed you quickly realise you need to think ahead. Stopping is more "plan this" than "grab and it just does it", and on less-than-perfect surfaces, that's not my favourite experience.
Battery & Range
Both scooters play the usual manufacturer range game: optimistic on the box, more conservative in reality. In mixed real-world riding - a bit of full throttle, a bit of eco, a few hills, normal adult weight - the Acer comfortably lands in the mid-thirties of kilometres before you start hunting for a socket. That's enough for most commuters to do a return trip with some errands and still have a buffer.
The Razor C45, despite the decent battery, is noticeably thirstier. Push it in Sport mode and that extra speed and motor punch cost you. You're realistically looking at something more in the low-to-mid twenties for most riders using it as intended, maybe a bit more if you baby it in slower modes. Fine for shorter commutes, less ideal if you're stacking several trips into one charge.
On the charging front, both are in the "leave it at work or overnight" category. The Acer tops up a bit quicker relative to its capacity; the Razor takes a touch longer for a smaller effective real-world range, which doesn't exactly win it friends. Neither offers fast charging miracles, but the Acer feels less like it's wasting your time.
Range anxiety? On the Acer, you're generally relaxed as long as you vaguely know your distances. On the Razor, you start checking the battery a bit earlier if you're living in Sport mode. It'll do the job for sensible commutes, but it doesn't leave much margin for spontanteous detours.
Portability & Practicality
Neither of these is a featherweight, but there's nuance. The Acer sits just under the "this is annoying now" threshold for occasional carrying. Up one or two flights of stairs, into a car boot, onto a train - manageable, if not exactly joyous. The folding mechanism is straightforward and locks positively, and the folded package is reasonably tidy, even if not ultra-compact.
The Razor is slightly lighter on paper, but the steel frame and big front wheel make it feel bulkier in real use. The folded footprint is longer and more awkward in narrow train aisles or small lifts. You can certainly lug it, but as soon as you have to combine walking and scootering regularly, you start questioning your life choices.
Day-to-day practicality favours the Acer: better weather protection rating, indicators for safer lane changes, a more polished app experience for basic locking and stats, and a deck that feels a bit more forgiving for varied foot positions. The Razor's strengths are more old-school: that flat-free rear tyre is brilliant if you're allergic to puncture repair, and the steel chassis shrugs off cosmetic abuse quite well.
Safety
Safety is where the Acer quietly feels like it belongs in 2025 and the Razor feels a bit more 2018-with-upgrades. The Acer's lighting package, including proper indicators and a reactive rear light, makes night riding in traffic noticeably less stressful. You can indicate without taking a hand off the bars, and drivers actually see what you're planning to do - a luxury most scooters in this class still don't offer.
The Razor has a decent headlight and a functioning brake light, and that UL battery certification is a real plus for fire safety peace of mind. But in traffic interaction terms, it's basic: no indicators, less sophisticated braking, and that harsher rear end which doesn't help when you're trying to maintain control over broken surfaces.
Tyre-wise, both have reasonably grown-up wheel sizes, but the Acer's matched air-filled tyres and front suspension combo give more mechanical grip and stability over varied terrain. The Razor's big front tyre is excellent, the solid rear is acceptable on good roads and borderline rude on bad ones.
If you ride year-round, at dusk, in rain, or anywhere with impatient drivers, the Acer's safety package simply feels more modern and reassuring.

Price & Value
This is where the Razor C45 has a bit of an uphill battle. At its usual price, it's noticeably more expensive than the Acer while not clearly outperforming it in the areas most commuters actually feel every day - comfort, range, and refinement. You're paying extra for the brand, that bigger front wheel, the UL certification and the steel chassis. Those are not meaningless, but they don't fully compensate for the compromises elsewhere.
The Acer sits lower in price and still manages to bundle in suspension, brighter safety tech and a genuinely usable range. It feels more "appropriately priced" rather than a bargain, but in this segment that's already a win. You're not getting a miracle deal, but you are getting what you pay for - and in some respects a little more.
The Razor gets more interesting only when it's significantly discounted. At a strong sale price, its shortcomings are easier to forgive. At full retail, it's hard to argue it beats the Acer on value for a typical commuter who just wants a scooter that rides well and doesn't fuss.
Service & Parts Availability
Both Acer and Razor are real, global brands, which already puts them ahead of the mystery-label brigade. Acer leverages its existing electronics support network, especially in Europe, so getting warranty service or basic parts isn't a lottery. You're dealing with a company used to handling laptops by the truckload, which translates surprisingly well to scooters.
Razor, meanwhile, has years of experience shipping parts for its kick and kids' e-scooters. In many markets you can actually order spares fairly easily, and there's a long tail of third-party knowledge on how to keep Razor products running. That said, adult models like the C45 don't yet enjoy the same ecosystem depth as their classic kid models.
In practice, both are decently supportable. The Acer feels slightly more "2020s" in terms of documentation and app ecosystem; the Razor feels more old-school but competent. Neither is a nightmare; neither is boutique-level exceptional either.

Final Verdict - Which Should You Choose?
If you strip away nostalgia, marketing and spec-sheet posturing, the Acer ES Series 4 Select is the scooter that more people will simply get on with. It's comfortable enough for daily use on less-than-perfect streets, its safety kit is genuinely modern, the range is practical, and it doesn't ask a painful premium for the privilege. It's not glamorous, it's not wild - it's the kind of scooter you quietly trust to get you to work and back while you think about other things.
The Razor C45 is harder to place. The big front wheel and punchier motor are genuinely appealing, and if your riding is mostly on smooth paths with modest distances, it can be a solid, enjoyable tool - especially if you pick it up at a discount. But the harsher rear ride, weaker-feeling braking at speed and relatively poor value at full retail keep it from being the no-brainer it could have been.
If your commute includes broken pavements, wet weather, traffic interaction and more than a quick dash to the next tram stop, the Acer is the safer, saner choice. If you're lighter, ride on good tarmac, love that "steel tank" sensation and can find the Razor for well under its list price, it can still make sense - just go in with realistic expectations about comfort and range.

Overall Winner Declaration
In the Numbers Freaks Corner, the ACER ES Series 4 Select scores 6 points against the RAZOR C45's 4. In the Author's Category Battle, the ACER ES Series 4 Select gets 31 ✅ versus 10 ✅ for RAZOR C45.
Totals: ACER ES Series 4 Select scores 37, RAZOR C45 scores 14.
Based on the scoring, the ACER ES Series 4 Select is our overall winner. Between these two, the Acer ES Series 4 Select simply feels closer to what an everyday commuter scooter should be: calm, competent, and quietly reassuring, even when the weather and roads aren't playing nice. It might not excite on paper, but out on real streets it just works - and keeps your body and nerves intact. The Razor C45 brings some charm with its punch and big front wheel, but it never quite shakes the feeling of being a half-step behind in comfort and polish. If I had to live with one of them every day, keys on the hook and charger by the door, I'd reach for the Acer without much hesitation.
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.
