Dualtron Ultra vs InMotion RS - Two Aging Beasts, One Real-World Winner?

Fast Answer for Busy Riders ⚡ (TL;DR)

The InMotion RS comes out as the more complete scooter for most riders: it rides calmer at high speed, has more modern suspension, better weather protection, and feels more like a cohesive vehicle than a hot-rod project. The Dualtron Ultra still bites hard with its raw torque and proven off-road chops, but it's clearly a product of an earlier era - fun, fast, yet a bit crude next to the RS.

Pick the RS if you want a high-speed, long-range beast that can realistically replace a second car and handle rain without a meltdown. Choose the Ultra if you're more interested in bombing trails, tinkering, and owning a "classic" performance scooter with a huge community and easy parts. Both are overkill for beginners, but for experienced riders the RS simply asks fewer compromises.

If you want to understand where each scooter truly shines - and where the marketing fluff quietly falls apart - keep reading.

There was a time when the Dualtron Ultra was the poster child of "too much scooter". It redefined what an electric scooter could do, and for a while it had the high-performance segment largely to itself. Fast-forward a few years, and the market has caught up - and in many ways overtaken it.

Enter the InMotion RS: a newer "hyper-scooter" that tries to be clever where the Ultra was just brutal. Adjustable ride height, hydraulic suspension, serious water protection, and a design that feels more motorsport than garden-shed prototype. On paper, it looks like the Ultra's future self after a few years in engineering school.

But spec sheets don't tell you how your knees feel after an hour on broken city tarmac, or whether you actually trust a scooter at speeds where your brain starts doing insurance maths. That's where real riding comes in - and that's exactly what this comparison is about.

Who Are These For, and Why Compare Them?

Both the Dualtron Ultra and InMotion RS live firmly in the "overkill for 90% of people" category. They're huge, heavy, brutally fast, and expensive enough that you'll actually read the owner's manual. Twice.

They compete in the same rough price band, both promise car-replacing range, and both are pitched at experienced riders who've grown out of commuter toys. Think suburban or semi-rural riders with space to store them, daily distances long enough to justify the battery sizes, and a healthy disregard for what their local traffic laws say about scooter speeds.

Yet their personalities are quite different: the Ultra is old-school brute force with an off-road flavour, while the RS tries to be a thought-through, modern hyper-scooter. That makes them natural rivals for the same buyer who wants "a serious beast", but needs to decide between rawness and refinement.

Design & Build Quality

Pick up (or rather, try to pick up) the Dualtron Ultra and you immediately feel its heritage: chunky aluminium, exposed bolts, knobby tyres, and the general aura of a very fast toolbox on wheels. It looks like it was designed by someone whose main hobbies are welding and downhill mountain biking. Functional, rugged, but definitely on the industrial side of pretty.

The frame is solid and time-proven, but the fold is classic Dualtron: a beefy collar clamp that does its job when adjusted correctly, yet is notoriously prone to developing play if you ignore it. The rubber suspension arms, single stem, and under-deck wiring layout all scream "first wave of big scooters". It's not badly built - just obviously from an earlier design generation.

The InMotion RS feels like it arrived later to the party and actually looked at what everyone else did wrong. The C-shaped suspension arms, sharp lines, and automotive-style paint give it a more finished, intentional look. The transforming deck height isn't just a party trick; it changes the stance visually and functionally, from slammed "race mode" to a taller, SUV-like profile.

In the hands and under your feet, the RS feels tighter and more cohesive. Less creaking, fewer "DIY project" vibes. Where the Ultra feels like a very serious upgrade of a scooter, the RS feels more like a small electric moto that happens to have a deck instead of a seat.

If you care about design and the sense that every part was drawn on the same CAD screen, the RS clearly edges ahead. The Ultra counters with a proven, simple structure that's easy to understand and wrench on - but that's more a consolation prize than a real win in 2025.

Ride Comfort & Handling

Comfort is where the age gap between these two really shows.

The Dualtron Ultra uses rubber cartridge suspension. At speed on decent asphalt, it feels planted and composed, almost sportscar-like. Hit a larger bump, a drop-off, or a dirt jump and the system copes impressively well, absorbing heavy impacts without bouncing you into orbit.

The issue is the in-between - the everyday "broken city" scenario of patched tarmac, cracks, and small potholes. Here the Ultra's suspension feels noticeably stiff. After a handful of kilometres on rough urban streets, your knees and ankles start sending sarcastic feedback. The knobby off-road tyres add a constant hum and vibration on smooth pavement, so even when the surface is good, it never quite feels plush.

By contrast, the InMotion RS with its hydraulic, fully adjustable suspension is simply in another league. You can dial it soft enough that cobblestones become tolerable and rough bike paths feel almost civilised, or stiffen it for higher-speed canyon carving. The tubeless road-oriented tyres round out the package - fewer harsh vibrations, better compliance over small imperfections, and generally less fatigue over distance.

In tight manoeuvres, the Ultra's higher, more "towering" stance combined with a single stem and stiff suspension means you need a firmer hand and more body English to stay fully relaxed. The RS, especially in a lower height setting, feels more like you're standing inside the chassis rather than perched on top of it. That gives it a calmer, more confidence-inspiring feel when you weave through traffic, take fast sweepers, or correct mid-corner.

If your daily rides involve a lot of rough city surfaces or longer distances, the RS is clearly the kinder choice to your joints. The Ultra is fine for shorter blasts and off-road fun, but as an all-day platform, it shows its age.

Performance

Both scooters are ridiculous in the acceleration department. "Reasonable" is not on the menu here.

The Dualtron Ultra delivers its power in a very classic way: you pull the trigger in full dual-motor mode, and the scooter just hits. The take-off is abrupt, almost violent, especially if your weight isn't properly forward. It's that old-school square-wave torque slam: exhilarating, but also a bit crude. It's fantastic if you enjoy the raw yank of a hot-rod electric scooter, less so if you appreciate finesse.

The InMotion RS also launches hard enough to make your eyebrows migrate, but the sine-wave controllers smooth out the curve. You still get brutal torque and an eye-watering sprint to city speeds, but the power builds in a more progressive, controllable way. You feel less like you're hanging on to an angry dog and more like you're piloting something intentionally tuned.

At higher speeds, the Ultra absolutely keeps up with serious traffic and then some. But once you get deep into the upper range, you become acutely aware of that older chassis and suspension philosophy. It can do those speeds, but you need to be very awake, very balanced, and preferably very familiar with your local road surface.

The RS, thanks to its geometry, adjustable height, and more advanced suspension, simply feels calmer when the speedo climbs into the "lawyer territory" zone. That doesn't magically make it safe - the speeds we're talking about are still motorbike territory - but if you're going to be that foolish, the RS at least feels less twitchy doing it.

Hill climbing? Both scooters laugh at hills that make commuter scooters cry. The Ultra bulldozes steep climbs without much sag, especially in the higher-voltage versions. The RS, with its big motors and power reserve, turns nasty gradients into "shrug, that's cute" territory. If you're heavy or live in a hilly area, either will do; the RS just delivers its muscle with more refinement, where the Ultra relies on sheer force.

Braking performance is strong on both - proper hydraulic discs and regen mean stopping from silly speeds is more limited by tyre grip and rider technique than by the hardware itself. The RS edges ahead in feel: the combination of stable suspension and refined brake modulation makes emergency stops slightly less dramatic. The Ultra stops very hard too, but you're more aware that you're asking a pretty stiff front end and knobby rubber to cooperate.

Battery & Range

On paper, both scooters offer what I'd call "forget the charger for the day" capacity. In practice, the picture is more nuanced.

The Dualtron Ultra, depending on version, already has a very serious battery. Ride gently, keep speeds sane, and it can cover huge distances between charges. Ride it like most Ultra owners actually do - hard bursts, dual motor, lots of hills - and the real-world figure shrinks, but still comfortably supports a long commute plus playtime.

The InMotion RS takes that idea and just stretches it. The big, high-voltage pack, combined with more refined power delivery and generally better efficiency, means that even when you indulge your inner hooligan, you can still complete long rides without starting to mentally measure every hill in battery percentage. Cruising at brisk traffic pace, the RS simply holds on longer.

Charging is another difference. The Ultra with a basic charger will happily occupy a whole day on the socket. You can speed that up with faster bricks or dual charging, but realistically, you learn to plug it in early and often. The RS, when fed with two chargers, resets from empty to ready-for-another-epic-ride in a single afternoon or long lunch stop, which makes weekend touring less of a logistics exercise.

Range anxiety? On either scooter, only if you're doing something excessive. The difference is that the RS makes "excessive" a bit more achievable in a single day without a wall-socket dependency.

Portability & Practicality

Let's be blunt: neither of these belongs on a train platform in rush hour unless you enjoy being hated by strangers.

The Dualtron Ultra is heavy, but just about in the "two strong arms and some willpower" range for single flights of stairs. You can muscle it into a car boot if you're reasonably fit, and the folded size, while bulky, still plays relatively nice with hatchbacks when you drop the rear seats. Think of it as "just barely portable enough that you keep pretending it's portable".

The InMotion RS crosses that line into "No, really, don't carry this" territory. Its weight is such that anything more than a couple of steps is a gym session. The fold is secure but not particularly space-efficient, and getting it into a standard car boot without folding seats is an exercise in geometry and swearing. Once it's in place - garage, shed, ground-floor storage - it's fine. Moving it up or down stairs regularly? Not realistic for most humans.

In daily use, the Ultra's slightly more manageable weight and simpler form factor give it a small edge if you need to occasionally load it into a vehicle or shuffle it around tighter spaces. The RS answers with better weather protection and longer range, making it a stronger proposition as a true car alternative that mostly lives on the ground floor.

Neither is a good fit if you rely on public transport or live in a third-floor flat without a lift. In that scenario, the "practical choice" is honestly neither of them.

Safety

Safety at these speeds is mostly down to the rider - gear, skill, and judgement - but the scooter can make your life easier or harder.

The Dualtron Ultra's big pluses are strong hydraulic braking, a long, stable wheelbase, and those massive tyres that act like spinning gyroscopes at speed. On dry roads, once you're up and rolling, it can feel surprisingly composed. The downside is the combination of stiff rubber suspension, older geometry, and off-road knobbies. On wet tarmac, the tread pattern gives you noticeably less confidence, and the infamous stem play problems aren't exactly comforting when you're leaning on the bars at speed.

Lighting on the Ultra is... typical high-performance scooter stuff of its era: lots of pretty RGB and deck lights, not a lot of true headlight punch. You are visible, but you don't see as much of the road as you'd like at serious speed unless you bolt on aftermarket lights. It's a recurring upgrade in the Ultra community for a reason.

The InMotion RS is much more modern in its safety approach. Proper, bright front lighting that actually lets you ride at night without running on faith; integrated indicators; and a chassis that resists wobble even when you're doing speeds that should probably be left to motorbikes. The wide, tubeless tyres give better grip and feedback on wet and dry asphalt alike, and the hydraulic suspension keeps the tyres in touch with the ground over broken surfaces.

The RS' big trump card is water resistance. With serious IP ratings for both body and battery, it doesn't treat puddles like mortal enemies. You still need to respect lower grip in the rain, but at least you're not also worrying about electrics shorting out halfway home.

Purely from a safety-confidence standpoint - braking feel, stability, lighting, wet-weather sanity - the RS is the more reassuring platform, particularly for regular high-speed riding.

Community Feedback

Price & Value

Both scooters live in the "this could have been a motorbike" price territory. That means expectations are high - you're not just paying for speed, you're paying for an entire ownership experience.

The Dualtron Ultra offers a solid amount of battery, serious performance, and a proven platform. You also get the Dualtron badge, which does help with resale and parts availability. The issue is that in today's market, you're paying almost premium money for a design that, while still capable, no longer feels cutting-edge in suspension, waterproofing, or safety features. It's good value if you specifically want the Ultra formula, less so if you're just looking for "the best modern beast for the cash".

The InMotion RS is similarly priced, but you can see more of that money in the current tech: advanced suspension, better IP ratings, more refined controllers, real lighting, transforming geometry. It doesn't feel cheap by any means, but it does feel like you're financing engineering rather than nostalgia. As a tool to replace or significantly reduce car use, the RS makes a stronger value argument.

Neither is a bargain. The RS, however, feels like it gives you more future-proofed hardware per euro in 2025.

Service & Parts Availability

Dualtron, as a brand, has been around the block. The Ultra benefits massively from that legacy: distributors across Europe, well-stocked parts shelves, and a thriving aftermarket. Need a new swingarm, controller, clamp, or deck? Someone has it, and someone else has already made a better version. Independent workshops know these scooters inside out.

InMotion is no small name either, especially thanks to its electric unicycles, and its distribution network in Europe is pretty respectable. Parts for the RS are available via official channels, and the brand's track record on after-sales support is better than most "catalogue brands." That said, it's still a younger scooter; the deep third-party ecosystem and random eBay treasure chest that the Dualtron enjoys simply isn't as developed yet.

If you're the kind of rider who likes easy access to both OEM and aftermarket bits, the Ultra's ecosystem is currently stronger. If you prefer to deal with an official channel and don't mind less of a mod scene, the RS is fine - just slightly less established in that regard.

Parameters Comparison

Final Verdict - Which Should You Choose?

Judging these two side by side, the Dualtron Ultra feels like the charismatic old legend - still fast, still fun, still dangerous in the right (or wrong) ways - but not quite up to what newer designs are doing with the same money. It's a known quantity with a big fan base, fantastic off-road manners, and a parts ecosystem that makes long-term ownership relatively straightforward. If you live half-on-dirt, love tinkering, and want something proven rather than modern, it still has its place.

The InMotion RS, though, is simply the more rounded machine. It rides better on real streets, behaves more predictably at extreme speeds, laughs at the rain, and offers proper lighting and suspension that don't feel like throwbacks. It's heavy and not exactly elegant to move around when switched off, but once you're rolling, it feels closer to what a contemporary hyper-scooter should be.

If I had to live with one as my main high-performance scooter, the RS is the one I'd keep in the garage. The Ultra still has a certain charm, especially off-road, but as an everyday beast in a modern European city, it's the RS that makes more sense more of the time.

These metrics look at how efficiently each scooter converts money, weight, power, and time into speed and range. Lower cost per Wh and per km/h indicate better "spec for your euro," while weight-based metrics show how much mass you drag around for a given battery or performance. Efficiency in Wh/km reveals how far each watt-hour takes you, and the power-to-speed and weight-to-power ratios hint at how aggressively a scooter can perform relative to its size. Finally, average charging speed tells you how quickly you can get back on the road after a deep discharge.
