Dualtron Thunder 3 vs Inmotion RS JET - Hyper-Scooter Showdown or Apples and Oranges on Steroids?

Fast Answer for Busy Riders ⚡ (TL;DR)

The Dualtron Thunder 3 is the more complete, more sorted hyper-scooter here: it rides like a mature flagship, feels bombproof, and backs its brutal performance with top-tier brakes, range and stability. The Inmotion RS JET punches above its price and delivers impressive 72V thrills, but it feels more like a cleverly cut-down racer than a true all-round flagship.

Pick the Thunder 3 if you want a "keep it for years" tank that can realistically replace a car and still terrify you on weekends. Choose the RS JET if budget matters more than ultimate refinement, you ride medium distances, and you want maximum speed-per-Euro without lugging a 50+ kg monster.

If you want to know which one will actually make you happier on your specific roads, in your specific life, keep reading-the devil (and the grin) is in the details.

Hyper-scooters used to be an eccentric niche: a few mad machines doing silly speeds with even sillier compromises. Those days are over. The Dualtron Thunder 3 and the Inmotion RS JET are part of the new generation-blisteringly fast, much better sorted, and aimed squarely at riders who want to forget what petrol smells like.

I've put serious kilometres on both of these, from grimy winter commutes to late-night top-speed runs on empty industrial roads. One is a big, heavy, unapologetic flagship that feels like a small electric motorbike. The other is a leaner, cheaper 72V hooligan that thinks it's a hyper-scooter but still wants to make it home in time for dinner.

If you're torn between them, you're already in dangerous territory-this is not a "first scooter" choice. Let's unpack who they're really for, where each one shines, and where the marketing gloss starts to crack.

Who Are These For, and Why Compare Them?

Both scooters live in the hyper-scooter world: dual motors, serious top speeds, and price tags that make rental scooters look like toys. They sit in that grey zone between "fast commuter" and "maybe just buy a motorbike instead."

The Thunder 3 is the established heavyweight: premium price, massive battery, obscene peak power and a long heritage in the Dualtron family. It's aimed at riders who want a serious, long-term machine with real range and don't mind a bit of heft.

The RS JET is the disruptor: same 72V class, but trimmed battery, lower weight and a noticeably lower price. It promises "hyper" sensations at what used to be high-end commuter money. You give up some range and outright muscle, but you save a lot of cash and a few kg.

You compare these two when you know you want 72V performance, are ready to wear real gear, and you're choosing between "stretch for the flagship" and "grab the value monster".

Design & Build Quality

Park them side by side and you immediately see the difference in philosophy.

The Thunder 3 looks and feels like a Dualtron should: industrial, overbuilt and slightly menacing. The chassis is a thick, forged slab of metal that doesn't creak, bend or complain, no matter how hard you push it. The deck is broad and confidence-inspiring, the folding clamp is finally worthy of the power, and all the little details-Higo connectors, long mudguards, reinforced kickstand-scream "we've learned from our previous sins". In the hands, every lever and bolt feels like it belongs on something faster than a scooter.

The RS JET goes for the futuristic "Transformer" aesthetic. It's sharp, edgy, with that black-and-yellow caution-tape vibe that basically yells at pedestrians before you arrive. The chassis is stiff and solid, cable routing is impressively tidy, and that huge colour touchscreen in the cockpit instantly makes most other scooters feel dated. But touch the folding area and the story changes a bit: the mechanism is strong when locked upright, yet the lack of a proper latch when folded makes it feel less well thought out off the road.

Overall build quality is good on both, but the Thunder 3 feels like a mature, third-generation flagship. The RS JET feels like a clever, high-value derivative of a flagship-solid where it counts, with a few practical rough edges left in.

Ride Comfort & Handling

On bad roads, the difference between "fast scooter" and "good scooter" becomes painfully clear-sometimes literally.

The Thunder 3 rides like a heavy sports tourer. MiniMotors' rubber cartridge suspension is firmer out of the box, tuned for stability first and comfort second. You still get a nicely damped ride: cracks, joints and average potholes get rounded off, not transmitted straight into your knees. Combined with those ultra-wide tubeless tyres, the scooter feels planted, almost reluctant to be knocked off line. At speed, that stiffness suddenly makes a lot of sense-the scooter holds its line through bumps instead of bouncing around.

The RS JET goes for tunable plushness. Its adjustable hydraulic suspension can genuinely be set from "sofa" to "track day." In the soft range, the JET is nicer over broken city asphalt than the Thunder 3; you glide over imperfections that the Dualtron still lets you know about. Crank it stiffer and it sharpens up, but it never quite shakes the feeling that it's lighter and a touch more nervous when the road gets really ugly at very high speeds.

In corners, the Thunder 3 feels like a big bike: wide bars, long deck, lots of grip. You lean in and it just carves, as long as you respect the mass. The RS JET is more playful and agile thanks to its lower weight and adjustable geometry-you can drop the deck and it suddenly begs to be flicked around. On tight urban runs and twisty cycle paths, the JET is easier to manhandle. On fast, open sweepers, I'd rather be on the Thunder.

Performance

This is where both scooters stop being sensible transport and start feeling like you've strapped yourself to a portable roller coaster.

The Thunder 3 is simply brutal. MiniMotors stayed with square-wave controllers, so power arrives like a punch, not a handshake. Even in conservative modes, a careless trigger pull will rocket you forward. Hit that "Overtake" function and it feels like the scooter grows a second personality: the already aggressive shove turns into a true "hold on or regret it" surge. High-speed runs feel almost surreal-the scooter keeps pulling hard long after your survival instincts start whispering that this is quite enough, thank you.

The RS JET is not as savage, but it's hardly tame. Its 72V sine-wave setup delivers power more smoothly and more quietly. Off the line it still lunges hard; you will absolutely leave cars behind at traffic lights. The midrange pull is impressive, and it will happily sit at speeds where traffic stops considering you "a scooter" and starts treating you like a small motorcycle. The big difference is character: the JET feels controlled and progressive, where the Thunder 3 feels like it's constantly daring you to misjudge your throttle.

Hill climbing is a formality for both. The Thunder 3 shrugs off nasty gradients without noticeable drama, even with a heavier rider. The JET copes very well too; on steep urban climbs it feels far superior to anything in the 60V mid-range world, though if you really abuse both back-to-back, the Dualtron has more in reserve.

Braking is one area where the Thunder 3 genuinely stands out: those four-piston hydraulics with big discs and eABS feel like you've borrowed stopping power from a motorcycle. The RS JET's hydraulic setup is good-strong and easy to modulate-but side by side, the Thunder's system feels a notch more serious and reassuring at truly silly speeds.

Battery & Range

On paper, one look at the batteries tells the story, and the saddle time confirms it.

The Thunder 3 carries a huge high-voltage pack with quality LG cells. In practice, that means long rides where you abuse the throttle and still come home with charge to spare. If you cruise more sensibly, you're into "I need a rest before the scooter does" territory. The key is how consistently it holds power: even when the gauge has dipped noticeably, the scooter still feels lively and willing, rather than "tired". Range anxiety just doesn't really feature unless you've genuinely misplanned a day out.

The RS JET's battery is smaller, but still substantial. Realistically, with enthusiastic riding you're in that "solid half-day of fun" window rather than "full-day tour." For commuting and spirited evening rides, it's more than adequate; you won't be babying the throttle the whole way home. Ride it harder and you'll see the battery tick down faster than the spec sheet suggests, but that's par for the course in this class.

Charging is where the Thunder 3 quietly sabotages itself out of the box. The stock charger is comically slow for such a large pack; without a fast charger you're committing to sleep cycles, not coffee breaks. Most owners fix that with upgraded or dual chargers, and once you do, it becomes manageable. The RS JET, with its smaller pack and reasonable default charge time (especially with dual chargers), is simply easier to live with if you don't want to invest in extra charging hardware straight away.

Bottom line: if you want deep reserves and proper touring potential, the Thunder 3 plays in a higher league. If your rides are shorter but frequent, the JET's battery is "enough" without feeling stingy.

Portability & Practicality

Let's be honest: neither of these is a "throw it under the desk at the office" machine. But there are levels of pain.

The Thunder 3 is heavy in that "plan your route around stairs" way. Lifting it into a car boot is a two-handed, knees-bent operation that you don't want to repeat five times a day. The folding mechanism itself is excellent-solid, confidence-inspiring, quick enough-but once folded, you're still dealing with a massive, dense object. It's happiest rolling, not being carried.

The RS JET is lighter by a decent chunk, and you do feel that when manoeuvring it in garages or onto ramps. Still, "lighter" here doesn't mean "light"-you won't be casually tossing it over your shoulder. The real annoyance is the folded behaviour: because the stem doesn't latch to the deck, carrying it becomes a juggling act. You either hug it awkwardly or improvise with straps. For short moves it's fine; for daily train-station stairs, it gets old fast.

In everyday use, both scooters work well as car replacements if you have ground-floor storage. The Thunder 3 edges ahead with its more mature lighting, indicators, horn and overall road presence: cars tend to treat it like a serious vehicle. The RS JET fights back with that excellent screen, good water resistance and app extras like electronic lock and tuning, which genuinely improve the day-to-day experience.

Safety

At the speeds these machines can do, safety isn't optional; it's the whole game.

The Thunder 3 feels designed around "how do we stop people dying on this thing?" The steering damper, out of the box, is a game changer. High-speed wobble-once the curse of early Dualtrons-is essentially gone if you set it up sensibly. The big, bright headlights aren't "token LEDs"; they're proper road-illuminating beams you can genuinely ride by at night. Add the superb four-piston brakes, grippy wide tyres and IP-rated electronics, and you get a scooter that actually encourages you to use the performance because it feels composed when you do.

The RS JET is also strong on safety, just slightly more "version one" in a few aspects. Hydraulic brakes and big discs provide strong stopping power, the lighting package is decent, and the adjustable deck height can meaningfully improve stability at speed. Its IP rating is very solid for wet commutes. High-speed behaviour is good-no floppy stems or scary flex-but it lacks the out-of-the-box high-speed damping hardware and truly blistering headlights of the Thunder 3.

Both demand full motorcycle-level gear and a healthy respect for physics. If I had to put a new-but-experienced rider on one at high speed, I'd put them on the Thunder 3 purely because the chassis and safety package feel that bit more overbuilt and forgiving when things get sketchy.

Price & Value

Here's where the RS JET tries to flip the table.

The Thunder 3 costs significantly more, and you feel most of that extra money in the battery size, braking hardware, lighting and depth of refinement. You're paying for LG cells, a giant pack, heroic stopping power and a chassis that's already been iterated and debugged. For the rider who wants a true flagship they can keep for years and maybe rack up four-digit kilometre counts, the price makes sense.

The RS JET, meanwhile, offers 72V performance at a price point where you'd normally expect a strong 60V commuter. That's its killer move. You lose a chunk of range and the last slices of top-end madness, but you keep a premium frame, good motors, an excellent screen and proper suspension. For riders who don't actually need to ride half a region on one charge, the JET can feel like a far smarter buy on pure Euros-to-smiles conversion.

So: long-term do-everything flagship versus high-performance bargain. If your budget stretches freely and you want the best overall package, the Thunder 3 justifies itself. If you're counting every hundred Euros but still want real 72V fireworks, the RS JET is one of the best tricks in the current catalogue.

Service & Parts Availability

Dualtron has been around the block more times than most brands, and it shows in parts and community infrastructure. In Europe, spares for Thunder-series machines are relatively easy to source: brakes, swingarms, controllers, shells, even little cosmetic pieces. Third-party support is huge, too-aftermarket throttles, dampers, clamps, all widely available and well-documented.

Inmotion is no newcomer as a brand, but in scooters they're still building out the same level of support Dualtron enjoys. For the RS JET, parts are available, just sometimes slower or through fewer channels, especially for cosmetic and non-critical bits. On the upside, their reputation for sensible BMS design and battery safety from the unicycle world carries over here, and the app integration for diagnostics is a small but real advantage.

If you like to wrench on your own scooter and mod it heavily, the Thunder 3 lives in a much bigger ecosystem. If you're more of a "ride it, maybe service it once a year at a dealer" person, both are workable, with Dualtron still a nose ahead on availability and sheer volume of knowledge out there.

Final Verdict - Which Should You Choose?

Both of these scooters are properly fast, properly serious machines. But they're not equals chasing the same crown-they sit on different rungs of the hyper-scooter ladder.

The Dualtron Thunder 3 is the heavyweight king here. It delivers more power, more range, better high-speed composure and a more complete safety package. It feels like it has been built to a standard, not to a price. If you want a scooter that can honestly replace a car for many people-long commutes, big weekend rides, foul-weather reliability-and you're prepared to accept the weight and cost, this is the one that will still feel "enough" a few years down the line.

The Inmotion RS JET is the clever assassin from the lower price tier. It gives you real 72V performance, strong comfort and an excellent user interface for substantially less money and with a touch less bulk. For riders doing medium-length rides who care about value, tech features and adjustability, the JET is a very tempting proposition and far from a bad choice-it's just not the same depth of machine as the Thunder 3 once you start pushing boundaries regularly.

If you're chasing ultimate capability, long-range confidence and that feeling of riding something truly overbuilt, go Thunder 3. If you're chasing maximum performance for the money and you can live with a smaller tank and a few ergonomic quirks, the RS JET will make your old commuter feel like it belongs in a museum.
