Fast Answer for Busy Riders ⚡ (TL;DR)
If I had to live with just one of these, I'd take the Denver SEL-10820B - the extra voltage, stronger motor and larger front wheel simply make daily riding less frustrating and more capable, especially if your city isn't billiard-table flat. It feels more like a "real" transport tool than a tech gadget on wheels.
The Acer ES Series 3 is the better fit if your budget is tight, your routes are short and flat, and you care more about brand name, turn signals and low purchase price than punchy performance or comfort. Think cautious first-time rider, not scooter enthusiast.
Both cut corners somewhere; the trick is choosing the corners you can live with. Keep reading - the differences become very obvious once you imagine a week of actual commuting on each of them.
Electric scooters have finally reached the point where big-box brands and laptop makers are throwing their hats into the ring. On one side we have the Denver SEL-10820B, a no-frills "hardware-first" commuter with a beefier electrical system than you'd expect at its price. On the other, the Acer ES Series 3, a budget scooter from a PC giant that tries to win you over with brand familiarity, sleek looks and a very aggressive price tag.
I've spent enough kilometres on both to know exactly where the shine wears off. On paper, they look closer than they really are; on the road, their differences show up within the first few hundred metres. The Denver is the practical workhorse that doesn't really care how it looks. The Acer is the stylish office intern that's great at coffee runs but starts to sweat when you ask for anything more demanding.
If you're trying to decide which compromises you'd rather live with, this comparison will walk you through the real-world trade-offs, not just brochure promises. By the end, you'll know which one will still feel like a good idea on a cold, wet Tuesday morning.
Who Are These For, and Why Compare Them?
Both scooters live in the affordable, entry-to-lower-mid range commuter segment - the place where people want to stop taking the bus, but don't want to remortgage the flat for a premium dual-motor monster.
The Denver SEL-10820B targets riders who want a sturdier frame, a stronger push up hills, and can tolerate a bit of extra weight and some rear-end harshness for the sake of durability and power. It's pitched as a "real commuter" rather than a toy.
The Acer ES Series 3 is firmly a starter scooter: cheaper, lighter-feeling, and friendlier in appearance. It tries to win on brand trust, turn signals and "it just works" simplicity, rather than muscle or plushness.
They end up in the same shopping basket for one simple reason: both promise a sensible, low-cost way to handle short city trips. The question is whether you want a stronger transport tool, or the cleanest, cheapest way to try e-scooters without feeling like you bought something off a random marketplace seller.
Design & Build Quality
Pick them up and you immediately feel two very different philosophies.
The Denver is built like someone specced it from a warehouse catalogue of "things that don't break easily". Iron frame, steel stem, big 10-inch wheels, hybrid tyre setup. It has that slightly agricultural vibe: not elegant, but solid. Step on the deck and there's almost no flex. It feels like it was designed by an engineer with a checklist, not a designer with a mood board.
The Acer goes in the opposite direction. Aluminium frame, internal cabling, matte black finish with a discreet green logo - it looks like a consumer electronics product, polished and intentional. The folding joint feels reasonably tight out of the box, and the whole scooter looks tidier than most in its price class. But that sleekness also hides the fact that, structurally, it's a much lighter-duty machine.
In the hands, the Denver feels heavier and more industrial; the Acer feels cleaner and more refined, but also a bit more delicate. If you're the sort who leans their scooter against every lamppost and drags it up rough staircases, the Denver will forgive you more readily.
Ride Comfort & Handling
This is where the two part ways quite dramatically.
The Denver SEL-10820B gives you a proper air-filled front tyre, a basic front shock, and a large wheel diameter. On real city streets - expansion joints, manhole covers, the odd cobblestone stretch - that front end does a surprisingly good job of taking the edge off. The rear honeycomb tyre is stiffer and will remind you that you bought a budget scooter every time you hit a sharp bump, but overall the Denver feels noticeably more forgiving and confident, especially at its modest top speed.
The Acer ES Series 3 rides exactly like what it is: a solid-tyre scooter with no suspension and smaller wheels. On smooth tarmac it glides along pleasantly and feels nimble. The moment you venture onto rougher paths or old city streets, the vibrations come straight through your legs and hands. After a few kilometres of broken pavement, you'll be riding with bent knees by instinct, because your body becomes the missing suspension. It's tolerable for short hops, but you won't be volunteering to take the "scenic cobblestone route" twice.
In corners, the Denver's bigger front wheel and more substantial chassis feel more planted. The Acer turns quickly and predictably on good surfaces, but on anything loose or bumpy you're more aware of the smaller contact patch and firmer tyres. One feels like a small vehicle, the other like a neatly designed gadget that happens to have wheels.
Performance
Performance is where numbers on the spec sheet translate very directly to how often you swear under your breath.
The Denver uses a higher-voltage system and a noticeably stronger motor. Off the line, it doesn't rocket away, but it pulls with a confidence you rarely see in this price band. You feel it most on inclines: where typical budget scooters start wheezing and bleeding speed, the Denver chugs on and holds something resembling a respectable pace. You're still legal-ish, but you don't feel like a rolling roadblock every time the bike path tilts upward.
The Acer plays within the safe, legal 250-watt sandbox. On flat ground in top mode, it keeps up with casual cyclists just fine and the acceleration is smooth and beginner friendly. But the moment your route points even modestly uphill, the limits show. Gentle slopes are manageable, steeper ones turn into "kick-assist required" and anything more serious becomes a walking exercise. If your daily commute includes even one meaningful hill, you'll get tired of coaxing it along quite quickly.
Braking is more nuanced. The Denver's combo of front electronic and rear drum brake is very commuter-friendly: it's predictable, largely weather-insensitive, and needs almost no attention. The Acer counters with front electronic plus rear disc. When properly adjusted, the Acer can bite harder and stop shorter, but discs at this end of the market do tend to go out of tune or squeal if you're unlucky. Between the two, the Denver's setup feels more honest and maintenance-light; the Acer's feels sportier on day one, provided you keep an eye on it.
Battery & Range
On paper, the batteries look similar; on the road, the difference lies more in how they're used than in raw capacity.
The Denver runs a higher-voltage pack, which not only helps with torque but also keeps performance more consistent as the battery drains. In real commuting conditions - mixed speeds, a few hills, a grown adult on board - you can comfortably plan for a medium-length round trip with a buffer, as long as you're not riding flat out the whole way. Push it hard, load it up near its weight limit, and the range shrinks quickly, but that's true of almost every scooter in this class.
The Acer quotes optimistic figures, but with its milder motor and flatter target use, you can actually get reasonably close if you're light, patient and not in a hurry. Ride in top mode, at full speed, and you'll end up in a similar "solid but unspectacular" real-world range bracket. The upside is slightly shorter charging time, thanks to the relatively modest pack size.
In practice, if you do a typical city commute of a few kilometres each way, both will handle a day easily. The Denver feels less anxious when you add hills or a heavier rider into the equation; the Acer feels less painful when you forget to charge and need a quick top-up during work hours.
Portability & Practicality
Both scooters are "carryable", but neither is a dainty featherweight.
The Denver comes in around the mid-teens in kilograms, and you feel every gram of that iron frame when you haul it up a staircase. The folding system is simple and robust, and once folded it behaves like a slightly chunky piece of luggage. For short carries - into a lift, onto a train - it's fine. For long walks through giant stations, you'll start considering leg day officially covered.
The Acer is only marginally heavier on paper, but the aluminium construction and more compact folded form make it feel easier to manage. The latch system is straightforward, the stem clips down securely, and the proportions slip under desks and into car boots more neatly. If your daily routine involves frequent folding and carrying rather than just rolling from door to door, the Acer is the more civilised partner.
Both lack app integration in their current guises, which simplifies life for people who don't want another Bluetooth pairing in their lives. Both have decent water resistance ratings, with the Acer officially a notch higher, which is comforting if you live somewhere where drizzle counts as "clear skies".
Safety
Safety is a mix of hardware and how that hardware encourages you to ride.
The Denver scores well on fundamentals: larger wheels that shrug off small potholes instead of falling into them, a stiff frame, and a braking system that works similarly in dry and wet. The lighting is adequate - you're visible, but for truly dark paths you'll likely want an extra front light. At its modest top speed, stability is decent and you don't feel like you're on the edge of what the chassis can handle.
The Acer plays a different safety card: it adds turn signals, which is frankly a rare and welcome touch in this price echelon. Being able to indicate without taking a hand off the bar is genuinely helpful in traffic. Its rear disc can give strong stops, and the IPX5 rating means you worry a bit less about electrics in rain. However, the small solid tyres and lack of suspension do it no favours on sketchy surfaces - when things get bumpy or slippery, it's less forgiving than the Denver.
Overall, the Denver feels safer over bad infrastructure; the Acer feels safer in well-marked urban traffic where signalling and visibility matter more than absorbing potholes.

Price & Value
Sticker price is where the Acer makes a lot of noise. It undercuts the Denver by a noticeable margin, and for someone simply wanting the cheapest "serious" branded scooter, that alone can be persuasive. You get a recognisable logo, basic commuter functionality, and a few nice touches like indicators - all for what is essentially entry-level money.
The Denver asks you to spend more, but gives you a stronger electrical system, better hill performance, bigger wheels, front suspension and a higher load rating in return. If you actually depend on the scooter for daily transport rather than occasional fun rides, those things matter rather a lot. Over time, spending that bit extra to avoid daily frustration can feel like money very well spent.
Boiled down: the Acer is strong value as a low-commitment taste of micromobility; the Denver is better value as an actual transport appliance you expect to use and abuse regularly.
Service & Parts Availability
Both brands are widely distributed in Europe, but in slightly different ways.
Denver has long been a staple of supermarket chains and mainstream electronics retailers across the continent. That mass-market presence usually translates to easier access to generic spares and straightforward warranty handling at the shop where you bought it. The design is also conventional enough that any half-decent independent scooter workshop will know what to do with it.
Acer brings its global IT infrastructure mindset to the party. They're used to handling laptops and monitors, not brake cables and tyres, but their service network at least exists, which is more than can be said for many white-label brands in the same price band. That said, scooter-specific parts may not be as ubiquitous at street-corner repair shops yet, simply because Acer is still the new kid in this particular game.
In practice, neither is a nightmare, but I'd give a slight nod to the Denver for sheer "any local tech can figure this out" simplicity.

Final Verdict - Which Should You Choose?
From the saddle, the Denver SEL-10820B simply behaves more like a daily transport tool than the Acer. The stronger motor, larger wheel, front suspension and higher weight rating all add up to something that copes better with the messy reality of European cities: imperfect roads, occasional hills, and riders who are not fashion-model light. It's not glamorous, but it is capable.
The Acer ES Series 3 is more of a gateway drug into micromobility. It's affordable, looks good next to a laptop, and works nicely for flat, short urban hops where comfort and power are less critical. If you're price-sensitive, light, and your city is as flat as your bank account, it does the job - just don't expect it to grow with you if you start asking more of it.
If you want a scooter as an actual car or bus replacement for everyday commuting, I'd recommend stretching to the Denver. If you just want a cheap, branded way to try scooting around town without overthinking it, the Acer will scratch that itch - as long as your route is kind to it.
