Fast Answer for Busy Riders ⚡ (TL;DR)
The Dualtron Thunder 2 EY4 is the more complete, more serious hyper-scooter here: it hits harder, goes further, feels more bombproof, and has the ecosystem and support to match its brutal performance. The Inmotion RS Jet counters with a lower price, excellent tech (that touchscreen really is lovely), and a lighter, more approachable 72V package that's easier on the wallet and slightly easier on the back.
Pick the Thunder 2 if you want a "buy once, rule the road for years" machine with outrageous power and long-range capability. Choose the RS Jet if you want to step into the 72V club at a saner price, prioritise comfort, modern gadgets and don't truly need extreme range or top-end lunacy.
But the spec sheets never tell the whole story-keep reading to see how these two actually feel on the road, and which one fits your kind of riding.
Hyper-scooters used to be a niche for the utterly obsessed: a handful of monsters with more power than common sense. Now, we've got a whole tier of 72V animals, and two of the most tempting are the Dualtron Thunder 2 EY4 and the Inmotion RS Jet. On paper, they look like rivals; on the road, they have very different personalities.
I've put serious kilometres into both: city blasts, long countryside runs, late-night "let's just see how fast this really goes" moments. One is a heavy-metal tour bus with rockets welded underneath; the other is more of a tuned hot hatch trying to punch above its weight. Both are fast, both are fun, but they don't serve the same rider equally well.
If you're torn between "ultimate weapon" and "smart, fast, good-enough-for-most", this comparison will save you from a very expensive wrong choice.
Who Are These For, and Why Compare Them?
These two live in the same broad category: high-performance, dual-motor, 72V scooters that can comfortably cruise at car speeds and make your old 48V commuter feel like a rental toy. They're aimed at riders who already know which end of the scooter points forward and are ready to replace-or seriously reduce-their car usage.
The Thunder 2 EY4 sits firmly in the hyper-scooter luxury tier. It's for riders who want to ride long, ride fast and ride hard, and don't care that the scooter weighs roughly as much as a small moon. It's a no-excuses machine: you buy it instead of "the last four scooters you'll otherwise work your way through".
The RS Jet targets a more budget-conscious enthusiast: someone who wants that intoxicating 72V punch and real motorcycle-like speed, but doesn't need cross-country range or the thickest possible slab of battery in the deck. Think "first serious hyper-scooter" rather than "final endgame boss".
They compete because their real-world performance overlaps: both can outrun most traffic, climb ridiculous hills and feel like real vehicles rather than toys. The big question is whether you want the "best of the best" feel or the "best for the money" compromise.
Design & Build Quality
In the flesh, the Thunder 2 EY4 looks like a piece of military hardware that escaped from a sci-fi set. It's all matte black bulk, thick swingarms and that huge rear footrest that screams "I accelerate hard; brace yourself". The EY4 display finally gives Dualtron a cockpit worthy of its price: bright, modern, and integrated with a proper switch cluster that doesn't feel like it came from a bargain bin.
Everything on the Thunder feels dense. The deck is wide with a thick rubber mat that shrugs off rain and muddy shoes. The stem and double clamp feel overbuilt in the best way-once locked, nothing flexes, nothing creaks, it's just a solid bar of confidence. Wiring is still recognisably Dualtron-there's some spaghetti up front-but much more civilised than older generations.
The RS Jet takes a different visual approach: angular, transformer-like, with that black-and-yellow warning-tape aesthetic. It looks like it wants to fold into a robot at any moment. The frame itself is reassuringly rigid, with very tidy cable routing and a generally clean silhouette. It feels less "block of metal" and more "precision frame", lighter on its feet and less brute-force in construction.
Its party trick is the 4,3-inch touchscreen. As dashboards go, it's one of the best in the game: crisp, colourful, and actually legible in sunlight. It genuinely elevates the perceived quality. If you love tech, the Jet's cockpit wins on style and usability.
Where the difference shows is in perceived robustness. The Jet feels well-built and premium for its price, but the Thunder 2 feels like it was designed to survive the apocalypse and then do another 5.000 km for fun. If you're the type who rides hard and expects zero flex or drama, the Dualtron's build inspires more long-term confidence.
Ride Comfort & Handling
On the road, their suspensions tell you everything about their personalities.
The Thunder 2 ships with stiff rubber cartridges. At low to medium speed over broken city tarmac, you'll know about every pothole. It's not punishing like a solid-tyre rental, but it's definitely on the "sport" side. The trade-off is that, once you push into serious speed, the chassis feels rock solid-no wallowing, no vague bouncing, just a stable, planted line. Swap to softer cartridges and you can tame the harshness, but out of the box, it's tuned for aggression.
The wide, flat-profile tyres add to that "locked in" feeling in a straight line. They give a huge contact patch and make the scooter feel like it's glued to the road at speed, but they don't exactly fall into corners. You have to physically lean and muscle the Thunder into bends. It's more sports tourer than playful city carver.
The RS Jet is kinder to your joints. Its adjustable hydraulic suspension has a broader comfort window: soften it and it floats over nasty city surfaces in a way the stock Thunder 2 simply doesn't. Sharper edges and expansion joints are soaked up with much less drama, and the scooter feels more eager to change direction. The 11-inch tubeless pneumatics help here: enough volume for comfort, but with a rounder, more natural lean than the Thunder's square slabs.
Is it as locked-in at eye-watering speeds as the Thunder? Not quite. It's very stable-impressively so for its price and weight-but the Thunder's mass and geometry give it a slightly more "rail-like" high-speed feel. If your life is mostly lived at sane speeds over rough surfaces, the RS Jet is the comfier daily partner. If you regularly cruise fast on long, good roads, the Thunder 2's firmer, heavier stance feels more secure.
Performance
This is where things get properly silly.
The Thunder 2 is one of those scooters that makes even seasoned riders swear the first time they open it up. Full beans from a standstill feels like someone has stolen the ground from under your wheels. The dual motors hit with violent torque that doesn't really taper off as the speed climbs; that 72V system just keeps pushing. The "Overtake" function is essentially a "how brave are you really?" button: tap it at speed, and the scooter lunges forward again as if it had been holding back the whole time.
Top-end speed is firmly in "if you crash, you'll be on the news" territory. Getting to typical city limits happens almost comically quickly, and you have to consciously dial the power down in dense areas if you want to ride smoothly. Hill starts? Irrelevant. Long, steep climbs with a heavy rider? The Thunder 2 barely notices. It's one of the few scooters where you stop wondering if it can make a hill and instead start thinking about whether the road is long enough for you to stay sensible.
The RS Jet is no slouch. Far from it. Off the line, it punches hard enough to make most riders grin and slightly reconsider their life choices. From zero to city speeds, it feels very close to the big boys. The sine-wave controllers give it a wonderfully smooth ramp-up: gentle when you want, savage when you ask. At legal-ish speeds, it genuinely feels like a proper hyper-scooter.
Where you notice the gap is higher up the speed range and under sustained heavy load. The Jet can reach very serious numbers, but it doesn't have that extra reserve of violence the Thunder 2 keeps in its back pocket. Long highway-style blasts or repeated high-speed pulls show the difference in peak output and battery depth: the Dualtron feels like it was bred for this; the Jet feels like it's giving you almost everything it has.
Both brake very well with full hydraulic setups, but the Thunder 2's system, paired with its heavier chassis and grippy tyres, feels a touch more authoritative when you're scrubbing off big speed. It also has that electronic ABS pulsing through the levers-divisive in feel, but useful on sketchy surfaces. The Jet's braking is strong and predictable, just slightly less "anchor-dropping" once you really push the limits.
Battery & Range
Range is where the gap turns into a canyon.
The Thunder 2 carries a battery that could probably power a small village's lighting if you tried hard enough. Realistically, ridden like an adult with moments of childish throttle abuse, you can do long, fast rides and still come home with charge to spare. Even when you're behaving like a hooligan, you can string together genuinely long journeys without the battery gauge becoming the star of the show.
On more moderate rides-mixed riding, some restraint, some fun-you're looking at distance figures that most scooters only ever see in marketing brochures, not in real life. It's one of the few electric scooters where "range anxiety" is something you read about, not something you feel. The downside, of course, is that recharging with the stock charger is an overnight-and-then-some affair unless you invest in faster chargers.
The RS Jet trims the battery to keep price and weight in check. Real-world, when you ride it the way it begs to be ridden (lively, using the power, not crawling in Eco), you're in solid mid-range hyper-scooter territory: plenty for brisk daily commuting, plenty for a spirited weekend blast, but not the sort of thing you take on a full-day, constant WOT tour without planning charging stops.
Efficiency is decent thanks to the 72V system, and the dual-charge capability makes turnaround times reasonable if you invest in a second charger. For most riders, the Jet goes far enough; for some, the Thunder 2 goes as far as they need plus another whole afternoon they hadn't planned for.
Portability & Practicality
Let's be honest: neither of these is a "fold, tuck under your arm, hop on the tram" scooter. They are both big, heavy machines. But there are degrees of ridiculous.
The Thunder 2 is firmly in the "this is a vehicle, not an accessory" camp. Moving it up stairs is a workout. Lifting it into a car boot is a technique, not a casual action. The folding mechanism is strong and reassuring, but this is about reducing height for storage or transport, not making it "portable" in any normal sense of the word. If you don't have ground-floor access or a lift, think very hard.
The RS Jet, while still heavy, is noticeably less back-breaking. You can, with care and reasonably normal human strength, lift it into a car by yourself without needing a protein shake and a lie-down afterwards. The flip side is the folding experience: once folded, the stem doesn't lock to the deck. This makes carrying it awkward, as you're effectively wrestling two moving parts at once. It's a strange oversight on an otherwise thought-through design and makes short carries more annoying than they need to be.
In daily use, both are practical as car replacements: good weather protection, big tyres, strong stands, proper lighting and enough presence to make you feel like you're on a real road-going machine. The Dualtron's app and EY4 display add nice quality-of-life touches like digital locking and better battery monitoring; the Jet's big touchscreen and app do much the same, with an arguably nicer day-to-day interface.
Overall: the Jet is slightly less of a pain to manhandle off the ground, but the Thunder 2 feels more sorted once you're actually riding and living with it as a primary vehicle.
Safety
Both scooters take safety seriously, which is good because at their top speeds, you really need them to.
The Thunder 2's braking setup is superb: proper hydraulic callipers, big rotors, strong bite and good modulation. Combined with the chunky tyres and sheer weight pressing everything into the tarmac, emergency stops feel controlled and powerful rather than panicky. The electronic ABS is a love-it or leave-it feature: some riders hate the vibration, but it can save your skin on loose surfaces by preventing a full lock-up when your instinct is to grab a fistful of brake.
Lighting on the Thunder has come a long way from the old "neon show, no beam" days. Turn signals, a high-mounted rear light in the footrest and plenty of side visibility lighting make you properly noticeable. The low-mounted headlights are OK for being seen and for slower night riding, but if you're doing serious speed in the dark, you'll still want a bar-mounted auxiliary light for better throw.
The RS Jet also brings a strong safety package: full hydraulics, wide tubeless tyres and very stable geometry, especially with the deck set low. The braking feel is smooth and progressive, very easy to modulate, and it hauls the scooter down from speed with conviction. Lighting is good, with a bright headlight that does a decent job of showing road texture and proper indicators to keep your hands on the bars while signalling.
Water resistance is slightly better on paper for the Jet, and Inmotion has a strong reputation for conservative, safe battery management. The Thunder 2, meanwhile, offers solid water protection for the body and excellent waterproofing for the display, as long as you're not trying to run it through biblical floods.
Both are safe-if the rider respects them. The Thunder 2 simply operates in a higher risk band because of its ferocious performance; the Jet feels a little more forgiving, both in power delivery and chassis behaviour.

What riders complain about Enormous weight making it a nightmare on stairs and in cars; stiff stock suspension and square tyres leading many to immediate upgrades; lack of single-motor mode; twitchy low-speed throttle; long charging times without fast chargers; kickstand and absence of stock steering damper at this price raise eyebrows. |
What riders complain about Still heavy and awkward to lift; folding stem not latching to deck; handlebar height not ideal for very tall riders; app setup can be finicky; range drops quickly when ridden hard; parts availability and accessories sometimes slower than the older big brands. |
Price & Value
There's no way around it: the Thunder 2 EY4 is a serious financial commitment. You're well into "decent second-hand car" territory. But in the context of hyper-scooters, what you get for the money is compelling: premium battery cells, monstrous performance, huge range, strong safety features and the backing of one of the most established brands in the game. You're not paying a fashion tax; you're paying for engineering, longevity and support.
The RS Jet undercuts it dramatically, and that's where its magic lies. You get a 72V platform, dual motors, hydraulic suspension, a superb touchscreen and strong build quality at a price that normally buys you a high-end 60V scooter. If your priority is maximising performance per euro spent and you can live with less range and slightly lower extremes, the Jet is undeniably the better "deal".
Value, though, isn't only about money; it's also about how long you'll stay satisfied. The Thunder 2 feels like the kind of scooter you grow into and very rarely outgrow. The Jet feels like the perfect sweet spot for many riders-but a subset will, eventually, look at the bigger battery and grunt of the Dualtron and start dreaming again.
Service & Parts Availability
This is one of the areas where Dualtron quietly crushes a lot of competition. The Thunder 2 benefits from a huge, mature ecosystem: established distributors, loads of online shops stocking every imaginable part, and a massive global community producing guides for everything from tyre changes to controller swaps. If you ride a lot and plan to keep the scooter for years, this matters far more than most people admit when they click "buy".
Inmotion is no newcomer, especially in the electric unicycle world, and their scooter support is improving quickly. The RS platform is popular enough that parts are available in Europe, though not quite at the "I can get this from six shops by Friday" level Dualtron enjoys. Repairs are straightforward for any competent PEV shop, but if you're in a smaller market or like to DIY, you'll occasionally wait longer for certain components.
In short: RS Jet support is acceptable and improving; Thunder 2 support is already excellent and battle-tested.

Final Verdict - Which Should You Choose?
If you strip away the marketing and look at how these scooters behave in the wild, the Dualtron Thunder 2 EY4 is the more complete, more serious machine. It gives you monstrous performance, huge real-world range, rock-solid high-speed stability and an ecosystem that makes ownership straightforward even after thousands of kilometres. It's heavy, it's expensive, it's overkill-and it's brilliant at being all of those things.
The Inmotion RS Jet is the smart disruptor. It brings you into the 72V world at a price that doesn't require selling organs, with genuinely good comfort, excellent tech and plenty of real-world speed. If your riding is mostly commuting, spirited weekend blasts and the occasional longer ride-but not all-day, flat-out touring-the Jet will make you very happy while leaving cash in your pocket for gear and upgrades.
If you're the kind of rider who wants a scooter that feels like a long-term, do-everything flagship, go Thunder 2 EY4 and don't look back. If you want maximum grin per euro, can live with less battery and are comfortable with a slightly less "tank-like" platform, the RS Jet is a very savvy choice. Between the two, though, the Thunder 2 still wears the crown as the more complete hyper-scooter package.

These metrics show, in pure maths terms, how efficiently each scooter converts euros, kilograms and watts into speed, range and charging convenience. Lower "per Wh" and "per km" numbers mean you're getting more energy or distance for your money or weight. The power-to-speed and weight-to-power ratios highlight how aggressively a scooter can use its power and how much mass each watt has to move. Average charging speed simply tells you how fast the battery can refill: higher means less time tethered to the wall.
