Dualtron Ultra 2 vs Inmotion RS JET - 72V Heavy-Hitters, But Only One Is a True Legend

Fast Answer for Busy Riders ⚡ (TL;DR)

The DUALTRON Ultra 2 is the overall winner here: it pulls harder, goes further, feels more bombproof, and has the kind of long-term pedigree the RS JET simply hasn't earned yet. If you want an "endgame" scooter that can double as a dirt bike substitute and still cruise calmly at traffic speeds, the Ultra 2 is the more complete machine.

The INMOTION RS JET makes sense if you want 72V thrills at a lower price, care about modern features like a big touchscreen and IP rating, and don't need ultra-long range. It's a strong value play and a good entry into the hyper-scooter world, but it feels more like a clever shortcut than a future classic.

If you're serious about performance and long-term ownership, read on-the differences become very clear once you imagine living with each scooter day after day.

High-performance scooters used to be simple: if you wanted something borderline insane, you bought a Dualtron and tried not to fall off. These days, brands like Inmotion have crashed the party, waving sleek designs, colour screens and very tempting price tags. That's exactly the clash we have here: the DUALTRON Ultra 2, the off-road legend with a 72V war chest, versus the INMOTION RS JET, the "budget hyper" that promises similar voltage for a lot less money.

On paper, both scooters scream the same things: brutal torque, serious top speed, and enough battery to turn a "quick ride" into a half-day outing. In reality, their personalities are very different. One feels like a battle-proven machine built by people who've been doing this forever; the other like a bright, talented newcomer trying to impress with features and pricing.

If you're torn between old-school, over-engineered muscle and new-school, high-tech value, this comparison will help you figure out which side of that fence you actually belong on.

Who Are These For, and Why Compare Them?

Both scooters live in the same dangerous neighbourhood: high-performance, dual-motor 72V machines that can comfortably outrun city traffic and embarrass entry-level motorcycles off the line. You don't look at either of these if you're just hopping down to the bakery.

The Ultra 2 is for riders who want something that feels like a proper vehicle, not a gadget. Think heavy riders, long-distance maniacs, off-road explorers, and people who typically ride in "Turbo Dual" and call anything else "walking."

The RS JET targets riders who want that 72V punch without the 72V bank loan. It shaves battery capacity and a bit of overall brutality to slide into a more approachable price bracket, while adding tech and comfort tricks to sweeten the deal.

They compete because the RS JET essentially whispers: "Why pay Ultra 2 money when I'll give you big voltage, hydraulic suspension and a fancy screen for much less?" The Ultra 2 replies: "Because you want something that still feels strong after several thousand kilometres."

Design & Build Quality

Pick up (or try to) the Ultra 2 and the first word that comes to mind is "tank." Everything looks and feels overbuilt: thick swingarms, industrial stem, huge deck, exposed bolts that mean business. It's unapologetically mechanical, more "military prototype" than consumer product. After a few hundred kilometres of hard riding, it still feels like you're standing on a solid metal bridge.

The RS JET goes for a more modern, techy aesthetic. The black and yellow scheme, clean cable routing and angular frame give it that sci-fi "Transformer" vibe. The chassis shares DNA with the bigger RS, so structurally it feels stout and quite refined. The touchscreen in the cockpit instantly makes every old-school trigger display look prehistoric.

Where you feel the difference is in perceived long-term robustness. The Ultra 2's frame, footrest "wing", and classic Dualtron hardware have been beaten to death by riders worldwide and proven to hold up. It creaks if neglected, sure, but it rarely feels fragile. The RS JET feels well engineered, but there's still a sense that the electronics and moving geometry will need time in the field before they earn the same "bulletproof" reputation.

If you're the sort who equates heft and visible engineering with durability, the Ultra 2 has that old-school confidence. If your eyes light up at big colour screens and neat cable management, the RS JET will look more "premium" out of the box.

Ride Comfort & Handling

These two ride very differently, even though they share similar tyre size and voltage.

The Ultra 2 uses Dualtron's rubber cartridge suspension. On the road, it feels firm and very planted. At speed, that firmness translates into a reassuring lack of bobbing or wallow-you point it straight and it just tracks. On broken city tarmac, though, especially if you're lighter, the scooter lets you know about every pothole in the municipality. After a few kilometres of bad cobblestones, your knees may open negotiations.

The RS JET's adjustable hydraulic suspension is the opposite philosophy: you tune the behaviour instead of just accepting it. Soften it and suddenly rough urban streets feel surprisingly civilised. Tighten it and the chassis sharpens up for fast riding. Combined with the adjustable deck height, you can go from "low, sporty street missile" to "higher, more forgiving trail mode" in a way the Ultra simply can't match out of the box.

In corners, the Ultra 2 feels stable and a bit conservative-wide bars (on newer versions) and that wide deck make it predictable. It likes sweeping, fast arcs more than tight slalom. The RS JET, with its lower potential centre of gravity and well-controlled suspension, feels a bit more playful and communicative on twisty asphalt, provided you've dialled in the settings correctly.

If your daily ride is rough urban terrain and you enjoy tinkering, the RS JET pampers you more. If you prioritise high-speed stability and don't mind a firmer feel, the Ultra 2's "planted tank" character is hard to beat.

Performance

Performance is where the Ultra 2 starts grinning and rolling its sleeves up.

On the Ultra 2, full throttle in dual-motor turbo mode feels like getting rear-ended by a small car. The 72V system and generously specced controllers hit hard right from the start and just keep pulling. You really do have to lean forward to keep the front end down, and the scooter barely seems to notice hills-steep inclines just become "slightly more interesting flat". Cruising at car speeds feels relaxed, almost lazy, as if the scooter is idling.

The RS JET is no slouch-it's properly quick, especially given its lower price bracket. It rockets to urban traffic speeds in a few heartbeats and keeps climbing smoothly. The sine-wave controllers give it a refined, controllable throttle: docile when you're weaving through pedestrians, angry when you open it up. It charges up hills with impressive eagerness, easily outclassing most 60V "performance" scooters.

But when you ride them back-to-back, the difference in sheer brutality shows. The Ultra 2 has that extra layer of violence and top-end authority; it feels like it always has more to give. The RS JET is fast and highly usable, but it never quite crosses into that "this is a small rocket" territory the Ultra 2 lives in.

Braking tells a similar story in a different way. Both scooters have hydraulic discs that inspire confidence, but the Ultra 2 adds a well-sorted electronic ABS system and pairs it with those huge, wide tyres. You can haul it down from silly speeds with a single finger and a bit of feel. The RS JET's brakes are strong and progressive; paired with its stable chassis, they feel natural. No real complaint there-just that the Ultra 2's whole high-speed package (power, mass, tyres, brakes) feels like it's been tuned for repeated abuse.

Battery & Range

This is the category where the Ultra 2 simply walks away.

With its huge LG battery pack, the Ultra 2 offers the sort of real-world range that makes you check your own body battery before worrying about the scooter's. Even when you ride like you stole it-dual motors, frequent hard acceleration, cruising at serious speeds-you can still rack up enough kilometres in one go that most riders will tap out before the scooter does. Ride more conservatively and you're into "day trip" territory.

The RS JET plays in a lower league here by design. Its battery is effectively a trimmed-down unit from the bigger RS: same 72V architecture, less capacity. In practice, that means real-world range comfortably good for longer commutes and energetic evening rides, but not the kind of "disappear all afternoon into the hills and come back at sunset" capability the Ultra 2 has. Push it hard and you'll see the gauge fall at a noticeably faster rate.

Charging is the Ultra 2's self-inflicted wound. Using the stock charger is like watching paint dry in real time; this is a scooter that basically begs you to buy a fast charger. Once you do, it becomes manageable, but it's an extra cost you effectively have to factor in. The RS JET charges quicker from the box and supports dual-charging too, making it easier to live with if you're not the planning type.

If you're a heavy rider, live in a hilly area, or like to ride long and hard without doing mental maths about whether you'll get home, the Ultra 2 is on a different level. If your everyday use is more moderate and you value shorter charge times without buying extra hardware, the RS JET is the more sensible choice.

Portability & Practicality

Let's not kid ourselves: neither of these is "portable" in the commuter-scooter sense. They're both heavy, they're both long, and carrying them up narrow staircases is a quick way to learn new swear words.

The Ultra 2 is the heavier and feels it. The classic Dualtron folding setup locks solidly when riding, but folding and unfolding is a bit of a ritual-clamps, screws, "is it tight enough?" checks. Once folded, it's reasonably compact length-wise and goes into a car boot, but lifting it in is a two-handed, "brace your back" manoeuvre. This is a scooter that ideally lives in a garage or at least on the ground floor.

The RS JET, despite being labelled the "baby RS", is still a big boy. Weight is similar on paper, but the slightly smaller battery helps a bit when you're muscling it about. The bigger annoyance is the folding practicality: the stem doesn't latch to the deck when folded, so the whole front end wants to swing around as soon as you pick it up. It doesn't sound like much until you try carrying it one-handed through a doorway. Many owners end up improvising with straps or just avoiding lifting entirely.

For daily life, both like predictable storage: garages, sheds, car boots, lifts. The RS JET's IPX6 rating gives it an edge for all-weather commuting-you're less stressed about surprise showers. The Ultra 2 has no official rating, so while many riders do take it in light rain, you're always slightly aware you're tempting fate.

As a "park outside the café" scooter, neither is ideal-they scream "steal me" from a block away. The Ultra 2's higher price and brand recognition means you'll be even more paranoid about leaving it unattended.

Safety

At the speeds these scooters can hit, safety stops being optional gear and becomes part of the core design. Both manufacturers know this, but they approach it differently.

The Ultra 2 focuses on mechanical fundamentals: big hydraulic discs, electronic ABS, fat tyres, and a long, stable wheelbase. At high speed, it feels calm rather than twitchy, especially with the newer, wider handlebars. The braking power matches the top end, so you don't have that uncomfortable "goes like a missile, stops like a rental" mismatch. Lighting is decent for being seen, with stem and deck lights and a proper rear light, but serious night riders will still want a powerful add-on headlamp to really see the road at crazy speeds.

The RS JET leans harder into modern safety features. Hydraulic brakes with large rotors, strong lighting including indicators, and that IPX6 rating all add up to a confidence-inspiring package for urban riding. The adjustable deck height lets you lower the centre of gravity for fast runs, which does wonders for reducing speed wobbles. Traction from the 11-inch tubeless tyres is ample, and the whole chassis feels nicely damped rather than nervous.

If your riding involves a lot of wet conditions or mixed traffic, the RS JET's indicators and water protection are big wins. For dry-weather, high-speed abuse, the Ultra 2's mix of ABS, tyre footprint and sheer stability makes it feel like the more serious tool.

Price & Value

This is where the RS JET makes its loudest argument. For a price that usually nets you a high-end 60V performance scooter, Inmotion hands you 72V, dual motors, hydraulic suspension, a big touchscreen, and proper water protection. You don't have to start adding a steering damper or display upgrades-it's pretty feature-complete out of the box. If your budget is capped and you want maximum "wow" per euro, the RS JET is extremely persuasive.

The Ultra 2 costs significantly more and doesn't try to compete on showroom flash. What you're paying for is a proven 72V drivetrain, a huge LG battery, a very robust chassis, and an ecosystem: easy parts, established dealers, endless rider knowledge. Over years and thousands of kilometres, that matters a lot more than the initial unboxing high.

If you view the scooter as a long-term vehicle and plan to really rack up mileage, the Ultra 2 justifies its premium. If you want to step up into serious performance without overspending, the RS JET is one of the best tickets in.

Service & Parts Availability

Dualtron's big advantage is age and scale. The Ultra 2 benefits from a massive global network of dealers, third-party shops and online parts sellers. Need a new motor, swingarm, suspension cartridge or random bolt? There's probably a shop within a country or two that has it on the shelf. YouTube is full of Ultra-family teardown and repair guides, and Facebook groups can walk you through almost any fix.

Inmotion is building that network, but it's still catching up in the scooter world. Their reputation from electric unicycles helps, and official distributors in Europe are getting better, but parts sometimes take longer to arrive and not every local shop is familiar with RS-series quirks yet. It's not bad, but it's not yet at "walk into any high-end PEV shop and they nod knowingly" level.

If easy service and guaranteed parts availability are high on your list, the Ultra 2 sits on much safer ground-for now.

Final Verdict - Which Should You Choose?

Choosing between these two is really choosing what you value most in a 72V scooter: raw, proven muscle and endurance, or modern features and strong value.

If you want a scooter that can genuinely replace a motorbike for many people-huge range, monstrous power, off-road capability, and a chassis that feels like it's carved from a single block of metal-the DUALTRON Ultra 2 is the one. It's not the cheapest, lightest, or most gadget-filled. It's just the scooter that, months and thousands of kilometres later, still feels like the right decision every time you crack the throttle.

If your budget is firmer, your rides are shorter, and you're drawn to tech, comfort tuning and proper water resistance, the INMOTION RS JET is a very smart, very fun choice. It gives you a taste of the hyper-scooter life with far less financial pain and a more forgiving day-to-day experience-so long as you're not chasing ultra-long range.

Personally, if I had to live with just one of them as my "serious" scooter, I'd take the Ultra 2. It feels more like a long-term partner than an exciting fling. But if I were stepping up from a mid-range commuter and watching the budget, I'd absolutely keep the RS JET on my shortlist-it's one of the few that genuinely earns its hype.

These metrics boil performance down to pure maths: how much you pay and carry per unit of energy, speed and power, how far each Wh actually takes you, how much punch you get per km/h of top speed, and how quickly the battery refills. Lower is better wherever cost, weight or consumption is involved; higher is better where we're talking about "how much oomph" (power density) and how fast you can get that energy back into the pack.
