Tiny Titans of the Last Mile: DENVER SEL-80135O vs RILEY RSX Plus - Which Lightweight Scooter Actually Deserves Your Money?

Fast Answer for Busy Riders ⚡ (TL;DR)

The RILEY RSX Plus is the stronger overall package: it rides more comfortably, brakes far more confidently, and feels closer to a "real vehicle" than a toy, even if you pay noticeably more for it. Its pneumatic tyres, proper disc brake and indicators make everyday commuting calmer and safer.

The DENVER SEL-80135O only really makes sense if your budget is tight and your rides are very short, flat and occasional - think school run distance, not cross-town mission. It's extremely light and cheap, but you feel every compromise in range, comfort and refinement.

If you want something you won't outgrow after a month, look at the Riley first; if you just need a colourful, throw-in-the-boot gadget for a few kilometres at a time, the Denver can still do a job.

Now let's dive into what living with each scooter is actually like - beyond the glossy marketing blurbs.

Electric scooters in this lightweight, "last mile" segment are all about trade-offs. You don't get monster power or touring range; you're buying portability, simplicity and the ability to beat walking without needing a gym membership to carry your ride.

I've spent time on both the DENVER SEL-80135O and the RILEY RSX Plus in exactly the environments they're built for: short urban hops, station connections, campus runs and the odd guilty pleasure blast along a riverside bike path. Both promise to be compact city tools; one leans hard into being cheap and featherweight, the other tries to feel grown-up and "vehicle-grade".

One-line version? The Denver is for people who really don't want to spend money. The Riley is for people who really don't want to regret not spending money. Let's unpack that.

Who Are These For, and Why Compare Them?

On paper, these two sit in the same lightweight commuter class. Both top out around typical EU scooter speed limits, both are compact, both are aimed squarely at short city trips and teenagers / young adults / office commuters who need something that folds quickly and doesn't break their back on the stairs.

The DENVER SEL-80135O is the budget bomb: supermarket-shelf pricing, teen-friendly looks and a battery that screams "last kilometre", not "last suburb". It's squarely for people who look at premium scooters and say: "absolutely not, I just want something cheap that moves".

The RILEY RSX Plus floats a tier above, still very much entry-level but positioning itself as a serious commuter device: indicators, proper braking, removable battery, nicer ride. It costs more than the Denver, but it also feels like Riley at least expects adults to ride it regularly, not just kids on weekends.

They're natural rivals because the rider standing in a shop (or scrolling a webshop) will likely ask: "Do I save money now with the Denver, or stretch for the Riley and hope it's worth it?" This comparison is exactly about that decision.

Design & Build Quality

Pick up the DENVER SEL-80135O and the first reaction is usually: "Wow, that's light." Second reaction, a few seconds later, is often: "And yes, it looks like it cost what it cost." The bright orange accents are fun and visible, and the aluminium frame is serviceable, but the whole thing has that mass-market, big-box-store feel: functional, but with visible welds, cheaper plastics and a general aura of "don't look too closely".

The folding joint and stem are adequate for its modest performance envelope, but you do notice more play and rattling after some kilometres, especially because of the solid tyres. It's not terrifying, just not confidence-inspiring if you're used to more refined scooters. The cables are out in the open, the grips are basic rubber, and the deck is on the narrow and short side.

The RILEY RSX Plus, in contrast, feels like someone cared about how it would look leaned against a glass office wall. The matte black finish, cleaner welds and largely internal cable routing give it a more "urban appliance" vibe than "cheap toy". The frame feels stiffer, and the overall impression in the hands is of a more cohesive, better-assembled product.

The folding latch on the Riley is chunkier and includes an extra safety catch. It can feel annoyingly stiff when new, but that tightness also means fewer creaks and wobbles on the road. The removable battery integration is neat rather than clumsy, and small details - like the indicator housings and LCD unit - feel a class above the Denver's utilitarian hardware.

In the hand, the Riley feels like something that might happily survive a couple of years' commuting with minor TLC. The Denver feels like it'll happily survive if you keep expectations, weight and mileage modest.

Ride Comfort & Handling

This is where the spec sheets really translate into body language.

The Denver rolls on small honeycomb solid tyres with a basic front spring. On smooth tarmac, it's fine - almost pleasant, especially at modest speeds. The moment the surface deteriorates, the scooter reminds you exactly what you saved money on. Expansion joints, brick pavements and rougher asphalt all transmit a continuous buzz into your hands and knees. After around five or six kilometres of mixed city surfaces, I found myself subconsciously hunting for the smoothest possible line like a road cyclist in denial.

Steering on the Denver is light and a bit nervous, mainly because of the small wheels and low weight. Quick slaloms around pedestrians are easy, but high-speed stability is not its strength; it's happiest pottering along at moderate pace on decent surfaces. The narrow deck and fixed bar height make stance and comfort more of a compromise for taller riders.

The Riley, running noticeably larger air-filled tyres and also sporting front suspension, is simply in another league for comfort in this category. The tyres swallow the constant chatter of old pavement and small potholes, so where the Denver chatters and skips, the RSX Plus hums and glides. You still feel big hits - it's not a dual-suspension cruiser - but vibration fatigue sets in much later.

Handling-wise, the Riley feels more planted. The front hub motor and battery weight in the stem make the steering a little heavier than some might like, but you quickly adapt. In tight city weaving it's agile without feeling twitchy; at maximum speed on a bike lane it inspires more confidence than the Denver thanks to that extra tyre volume and stiffer frame. Longer rides are simply less punishing.

If your typical outing is a kilometre or two, the Denver's harsher ride is tolerable. Stretch that to real commuter distances and the Riley's relative sophistication starts to feel much less like a luxury and more like self-preservation.

Performance

Neither of these scooters is going to rearrange your shoulders when you hit the throttle, and that's fine - they're built for legality and approachability, not drag races.

The Denver's front hub motor sits at the very bottom end of the power spectrum. Off the line, acceleration is gentle, almost shy. For total beginners or younger riders, that's welcoming; there's no surprise surge, no drama. You build up to its limited top speed in a calm, linear way, and on flat ground it will sit there reasonably happily until the battery dips below the halfway mark, at which point it starts to feel a bit wheezy.

The cracks start to show the moment you point it uphill. Modest inclines it can shuffle up if you're light; add a heavier rider or a steeper ramp and you're quickly in "help it with kicks" territory. It's very obviously tuned for flat northern European cities and short hops. Try to bully it into serious hill climbing and it sulks.

The Riley's motor isn't some powerhouse either, but the extra grunt is immediately noticeable. Off the line it still feels civilised - more "confident stride" than "sprint" - yet it gets to its speed limit briskly enough that keeping up with push-bikes in the bike lane isn't an embarrassment. There's enough punch in the mid-range that headwinds and slight inclines don't instantly kill your pace.

On typical city bridges and gentle hills, the RSX Plus holds its own for average-weight riders. You feel it working, but you're not forced to dismount and push. On steeper stuff or with heavier riders it will slow and eventually grind down, but compared directly to the Denver, it's the one that feels like a real transport tool rather than a fair-weather toy.

Where the Riley really pulls ahead is braking. The Denver relies on an electronic front brake and an old-school rear foot brake. Used calmly, it'll stop you - but hard stops require practice, and using a fender brake at speed while shifting your weight back is not something I'd hand to every teenager in busy traffic. Modulation is limited and it never quite gives that "I can stop right now if I have to" confidence.

The RSX Plus brings a hand-operated disc brake at the rear and electronic braking at the front. Together, they feel familiar to anyone with cycling experience and allow much more precise speed control. Panic stop on the Riley, and you feel the system digging in without the front wheel trying to dump you over the bars. The result is simple: on the Riley, I was far happier riding at the upper end of its speed envelope; on the Denver, I instinctively left a bigger margin for error.

Battery & Range

Here's where marketing optimism and physics meet reality.

The Denver's battery is tiny - very tiny by modern scooter standards. The brand's heroic lab-condition range claim might look just about respectable on paper for a featherweight rider on billiard-table asphalt, but in the real world, with an adult on board and a normal mix of starts, stops, and imperfect surfaces, you're looking at a handful of kilometres before the power noticeably sags. You can absolutely commute on it if your one-way trip is very short, but plan anything beyond a quick station connection and range anxiety becomes part of the experience.

The one upside of such a small battery is charge time: it refills fairly quickly, and a mid-day top-up at the office is realistic. But the flipside is brutal: it's almost too easy to run it down entirely if you misjudge your route by "just one more detour".

The Riley's pack isn't huge either - that's the price of keeping the scooter properly portable - but it's substantially more generous than the Denver's. In practice, that means inner-city loops in the low double-digit kilometre range are doable without hitting the red zone, especially if you're not hammering performance mode all the time.

Is it a long-range cruiser? No. If your round trip is pushing into the high teens in kilometres every single day, you'll either be charging at both ends or looking at larger scooters entirely. But in my testing, a typical city user with a sub-10 km return journey is in a much more comfortable place on the Riley than on the Denver, and the removable battery gives you a sneaky upgrade path or spare-pack option that the Denver simply doesn't offer.

Portability & Practicality

This is the one category where the Denver gets to flex - such as it can flex with that small motor.

At well under eleven kilos, the DENVER SEL-80135O is genuinely featherweight. You can carry it up several flights of stairs without feeling like you've joined an involuntary fitness programme. The folded package is small, and the latch that hooks the stem to the rear fender makes it reasonably easy to tote like an oversized briefcase. On a crowded train or bus, it's compact enough not to gather murderous stares from fellow passengers.

The Riley is still light by scooter standards, but you do feel the extra couple of kilos. Carrying it one or two floors is no drama; lugging it repeatedly up long stairwells every day is more of a "doable but noticeable" exercise. The folded footprint is respectably compact, and the geometry when carried by the stem is better balanced than many scooters I've tested. It also feels more solid when you plonk it in a luggage rack or stand it in a corner - fewer wobbly bits waiting to catch on something.

Where the Riley claws back points is in daily convenience: the removable battery lets you leave a cleaner, less-interesting-to-thieves frame in the bike room while charging the battery upstairs; the integrated indicators make mixed traffic less hair-raising; the kickstand is more robust. Overall, it's the one I'd rather live with every day, even though the Denver technically wins the "who can be picked up with fewer grunts" contest.

Safety

Safety is where the philosophical gap between these two really shows.

The Denver does tick the bare minimum boxes: front LED, rear light, reflectors, two forms of braking, some front suspension. At its modest speeds and intended short distances, that can be enough if you ride defensively and mostly on well-lit, segregated paths. But the small solid tyres reduce grip in poor conditions, the front light is more "I exist" than "I can see", and the braking layout isn't exactly beginner-proof in panic situations.

On damp cobbles or surprise gravel, the Denver's solid front wheel will happily remind you that rubber hardness and no air chamber isn't the recipe for heroic stopping distances. You adapt by slowing down more than you otherwise might.

The Riley, on the other hand, is clearly designed by people who pictured it mixing with actual traffic. Pneumatic tyres give noticeably better grip and predictability, especially in the wet. The triple braking system (front electronic with anti-lock, rear disc) allows far more controlled deceleration, even downhill, and the dual brake levers are intuitive for anyone who's ever touched a bicycle.

The headline act, of course, is the integrated indicators on the bars and rear fender. Being able to signal a turn without waving an arm around while standing on a small deck is a huge quality-of-life improvement. Lights front and rear are brighter and more modern-looking than the Denver's, helping you be seen as much as see. At the speeds these scooters ride, "confidence" often equals "safety": the more in control you feel, the fewer dumb mistakes you make, and the Riley simply feels far more like a predictable, communicative partner.

Price & Value

On raw sticker price, the Denver undercuts the Riley by a significant margin. If your budget ceiling is hard and low, that may feel like the end of the discussion. For that money, you do indeed get a folding electric thing that moves you faster than walking, which is still kind of miraculous when you step back.

But value isn't just what you pay today; it's how soon you find yourself wishing you'd bought something else. With the Denver, that moment arrives quickly if your routes grow longer, hillier or rougher, or if you start expecting it to replace public transport rather than just supplement it. The tiny battery and modest motor mean there's very little headroom beyond pure last-kilometre duties.

The Riley charges you more up front but gives you a scooter you're much less likely to outgrow in a few weeks. Better braking, more comfortable tyres, indicators, removable battery and a more serious build all add up. If you count how many bus tickets or short rideshares it can realistically replace, the payback calculation looks a lot healthier than the Denver's in everyday use.

If you truly only ever need to cover a couple of flat kilometres and cost is king, the Denver can justify its place. For pretty much anyone treating a scooter as proper transport rather than occasional toy, the Riley represents much clearer value.

Service & Parts Availability

Denver, as a mass-market electronics brand, has broad retail presence across Europe. That means you can find the scooters easily and, in theory, deal with a local shop if something goes wrong. In practice, service quality depends heavily on the particular retailer, and entry-level pricing usually translates to entry-level aftersales attention. Spare parts do exist, but you're not exactly joining a passionate ecosystem of tinkerers and upgrade parts.

Riley is smaller but more focused on scooters specifically, and it shows. The RSX Plus ships with a reassuring warranty period that many owners actually mention, and there's a clearer path to brand-direct support if something fails. The removable battery design also means the most failure-prone component can, in principle, be swapped without major surgery.

Neither brand is at the level of the biggest global scooter giants for parts ecosystems, but if I had to bet on which company will still be meaningfully supporting this particular model in a couple of years, I'd quietly point at Riley.

Portability & Practicality

Already touched on portability, but practicality also includes how they deal with weather, storage, and daily faff.

Both scooters carry similar splash-resistance ratings, which in real life means: drizzle is fine, storms are not. The Denver's under-deck battery and low ground clearance make kerbs and deep puddles something to avoid carefully, whereas the Riley's deck and frame geometry feel a bit more forgiving when you misjudge a ramp or speed bump.

Storage-wise, either will vanish under a desk or into a hatchback boot without drama. The Denver wins the "throw it anywhere" contest purely because it's so light and cheap that you worry a little less about it. The Riley, with its more polished finish and higher price, is the one you're more inclined to lock properly and treat kindly - though that's not exactly a bad thing for longevity.

Safety

Stepping back, the safety comparison is stark. The Denver technically has multiple brakes and lights, but it lives very much at the floor of what I'd accept for mixing with city traffic. Small solid tyres, limited lighting and rudimentary braking are only acceptable because the scooter is slower and meant for very short, presumably cautious trips.

The Riley, with its better tyres, brakes, and especially indicators, feels like it was designed by somebody who has actually ridden scooters in a capital city at rush hour. You can control your speed precisely, signal clearly, and rely on the tyres to behave predictably when the road gets patchy or damp. For newer riders, that's the difference between a scooter that's merely "legal" and one that actually lets you relax.

Final Verdict - Which Should You Choose?

Both scooters promise lightweight convenience, but they deliver it with very different attitudes. The DENVER SEL-80135O is brutally honest in its way: it's cheap, light, and will move you a few flat kilometres faster than your shoes. Then it wants a rest and a charge. Treat it as a short-hop gadget and you'll mostly be fine; try to make it your main urban vehicle and the cracks appear fast.

The RILEY RSX Plus asks more from your wallet, but repays you with a ride that feels calmer, safer and more grown-up. Better tyres, stronger brakes, a more capable motor and that removable battery turn it into something you can legitimately use every day without constantly checking the battery bar or scanning the road for every tiny crack.

If you're buying a scooter as an experiment, a toy for a teenager, or a boot-resident backup for short, occasional hops, the Denver can be justified - as long as everyone involved understands its limitations. If you're buying something to actually commute on, to bring you reliably to work and back in comfort without feeling like you cut every possible corner, the Riley RSX Plus is the clear choice.

Numbers Freaks Corner

These metrics are a nerdy way of asking: how much speed, range or energy do you get for each euro, kilo or watt? Lower "per something" values generally mean better efficiency or value, while higher "power per speed" or charging power reflect stronger performance or faster turnaround. In plain language: the Riley makes better use of its extra weight and money, while the Denver wins only where absolute weight and bare minimum top-speed cost are concerned.
