Fast Answer for Busy Riders ⚡ (TL;DR)
The Dualtron Thunder 2 EY4 is the overall winner here: it pulls harder, goes faster, and carries a far bigger, higher-end battery, making it the more serious long-range, high-speed machine for riders who want a scooter that feels closer to a small electric motorbike than a toy.
The Apollo Phantom 20 Stellar fights back with better weather protection, more comfort out of the box and friendlier electronics, making it a good fit if you value polish, app wizardry and cushy ride quality more than outright brutality and gigantic range.
If your heart wants maximum power and future-proof battery with rock-solid platform, go Thunder 2; if your head says "I want something fast but civilised, and I often ride in the rain", the Phantom 20 Stellar makes sense.
Now let's dive in properly - because the differences only really show once you imagine living with each scooter day after day.
Hyper-scooters used to be wild, half-finished experiments: lots of volts, lots of speed, and very little finesse. These two are from a newer generation, where performance no longer excuses sloppy design - at least in theory. On one side you've got the Dualtron Thunder 2 EY4, successor to a legend and very much built in the "more is more" school. On the other, Apollo's Phantom 20 Stellar, the slick, software-heavy contender that wants to be the everyday hyper-scooter you can actually live with.
The Thunder 2 EY4 is for riders who secretly wanted a superbike but ended up on a scooter - a hulking, overbuilt slab of aluminium and battery that treats hills like rumours and long rides like warm-ups. The Phantom 20 Stellar is for those who want serious speed and comfort wrapped in something that looks like a premium product rather than a science project escaped from a shed.
On paper they share a lot - dual motors, big batteries, long travel suspension - but the way they ride, and the type of owners they suit, are very different. Stick around; that's where things get interesting.
Who Are These For, and Why Compare Them?
Both scooters sit in that "I could have bought a used car instead" price bracket, aimed squarely at experienced riders who are done with rental toys and commuter folders. They're not last-mile tools; they're car replacements, weekend weapons, and serious long-distance machines.
The Thunder 2 EY4 lives at the upper edge of hyper-scooters: towering voltage, monstrous battery, and performance that starts flirting with motorway territory. The Phantom 20 Stellar is a notch tamer in raw numbers but tries to claw back ground with tech, refinement and weather protection. You'd cross-shop them if you want a high-end, dual-motor scooter that can handle real distances and proper speeds - but don't quite want to spend "exotic race scooter" money.
In short: same ballpark of money, same "big boy" segment, but very different approaches to what a top-tier scooter should be.
Design & Build Quality
Pick up the Thunder 2 (or rather, attempt to) and the first impression is density. It feels like someone machined it from a single block of metal and then bolted a tank to it for good measure. Industrial, sharp-edged, unapologetically mechanical. The frame and swingarms feel brutally overbuilt, the stem clamp is serious hardware, and the huge rear footrest looks like it came off a Dakar rally bike. Finish is better than older Dualtrons: cleaner cable routing, fewer random zip ties, and that big EY4 display finally brings the cockpit into this decade.
The Phantom 20 Stellar is the stylist in the room. Its frame lines are smoother, the "space grey" finish looks more designer than industrial, and the integrated DOT display makes the whole front end feel like a deliberate product rather than a collection of aftermarket bits. Cable management is tidy, the deck is sharp-looking, and the integrated Quad Lock preparation is a very "2020s commuter" touch. Apollo clearly wants this to look at home among modern e-bikes and EVs, not just among hot-rodded scooters.
Build quality? The Thunder 2 feels more old-school heavy-duty: thick parts, minimal flex, a sense that if you dropped it down some stairs the stairs would lose. The Phantom feels more "engineered" and slightly more delicate in its details - hinges, lighting, the integrated display - but still robust enough for daily abuse. In the hand, the Dualtron wins on sheer solidity, while the Apollo wins on visual coherence and perceived sophistication.
Ride Comfort & Handling
Comfort is where their philosophies really diverge. The Thunder 2 uses Dualtron's signature rubber cartridge suspension. Stock cartridges are on the stiff side of firm. On smooth tarmac it feels like a sports car on stiff coilovers: controlled, low drama, and wonderfully stable as you push the speedo towards numbers you probably shouldn't. On rough patchy city asphalt, though, you start to feel the hits in your knees and ankles. It's never abusive, but you're definitely aware you're on a performance chassis, not a sofa.
The upside: that stiffness pays you back in handling at speed. Long sweepers, high-speed lane changes and sudden evasive moves all feel planted, provided you're not ham-fisted on the bars. The wide, square-profile tyres add to that sense of straight-line invincibility, even if they do make quick transitions and lean-in a bit laboured. You steer the Thunder 2 with your whole body, not just your wrists.
The Phantom 20 Stellar, by contrast, tries to make bad roads disappear. The dual hydraulic shocks let the deck float over cracks and potholes with much less drama. On half-decent tarmac, it's genuinely plush - the sort of scooter where you realise, ten kilometres in, that you haven't thought about the surface once. At pace, that suspension also gives a nice, controlled dive and rebound when you brake or hit imperfections.
Handling on the Phantom feels lighter and more agile at urban speeds. Those chubby hybrid tyres grip well, and combined with the low-ish centre of gravity, you can lean it into corners with more ease than the Thunder, which always feels like a heavier, longer machine. The built-in steering damper on the Apollo also calms the bars without needing aftermarket additions, which is comforting when you're pushing faster roads.
If your riding is mainly high-speed road carving and open suburban stretches, the Thunder's firm, locked-down character is fantastic. If you live somewhere with battered streets and want to arrive with your joints still on speaking terms, the Phantom edges ahead in out-of-the-box comfort and light-footed handling.
Performance
Twist the throttle on the Thunder 2 and things go from "oh, this is quick" to "I may have made life choices" very rapidly. The dual motors deliver a shove that feels closer to a mid-range motorbike than a scooter. There's a definite sense of weight, but the acceleration steamrolls it; the horizon comes towards you in a way that still surprises me even after a lot of kilometres on it. The infamous "Overtake" mode takes that and adds another layer of "are you sure?" for short bursts - not something you casually hit in a busy city street.
The flip side of such ferocity is low-speed control. The Thunder 2's throttle can feel a bit binary below jogging pace. Once you learn to feather it, you can creep through pedestrians, but it takes a conscious, practiced touch. At any half-open position, the torque is simply huge; hills flatten under it and heavy riders barely dent its mood. Top-end stability, helped by the stiff chassis and wide rubber, is excellent - but you absolutely need your wits about you.
The Phantom 20 Stellar is no slouch, but its power delivery is...civilised. Still properly fast, still capable of making new riders squeak in Ludo mode, but the MACH 3 controller shapes the torque curve in a way that feels progressive rather than explosive. Off the line it leaps quickly, yet you can roll around at walking speed with far more finesse than on the Thunder. It's very easy to forget how quickly it's capable of going because it never feels strained.
At speed, the Phantom is stable and surprisingly relaxed, the damper taking the nervous twitch out of the bars. It doesn't quite have that brutal, barely-contained-animal feeling the Thunder 2 exudes at full chat; it feels more like a powerful, well-tuned GT car, happy to cruise fast all day rather than constantly daring you to go faster.
If you're chasing maximum drama and warp-drive torque, the Dualtron is the go-to. If you want something very fast but easier to modulate in city traffic and on mixed routes, the Apollo's "controlled chaos" approach makes living with that power less fatiguing.
Battery & Range
The Thunder 2's battery is, frankly, ridiculous in a good way. It's a huge LG-based pack that gives you the kind of real-world range where you start worrying about your legs before you worry about the charge level. Ride hard - genuinely hard, with repeated high-speed blasts and lots of climbing - and you can still knock out distances that smaller scooters only manage when you baby them in eco mode. Treat the throttle with some respect and it becomes easily a full-day, big-city-or-even-between-towns machine.
The cost of that giant pack is, of course, charging time. On the bundled charger it's a "leave it until tomorrow" job from low to full. With faster chargers it becomes manageable, but you still plan your charging the way you'd plan refuelling a touring motorbike: it's part of the lifestyle, not something you casually do in a café between errands.
The Phantom's battery is exactly half the Thunder's energy, using quality Samsung cells. In practice, that still means very solid real-world autonomy. Even riding briskly, you can commute serious daily distances with a comfortable safety buffer. You are, however, aware there's a ceiling; this isn't the same "go wherever and worry later" experience the Thunder's brute capacity gives you.
On the upside, that smaller pack means charging is far friendlier. Overnight on the standard charger is realistic even from low, and with faster charging it becomes easy to top up during the day. The regen throttle on the Apollo genuinely extends range in hilly environments too, especially if you develop the habit of using it instead of mechanical brakes for most slowing.
Simply put: if you want one of the longest-legged production scooters around, the Thunder 2 is in a different league. If you want enough range for big-city life and long fun rides without dedicating half your mains sockets to chargers, the Phantom is more than adequate.
Portability & Practicality
Let's be honest: neither of these is "portable" in any normal sense. They both inhabit the "I hope you have a lift and a ground floor entrance" category. The Thunder 2, despite being very slightly lighter on paper than the Phantom, feels like moving a small anvil with wheels. The deck is long, the stem thick, and once folded it's still a large, dense object. Lifting it into a car boot is doable, but it's a move you plan, not something you improvise after a long ride.
The folding mechanism on the Thunder is secure rather than quick. The double clamp is confidence-inspiring, but it's not a one-hand, ten-second operation. You gain rock-solid stem rigidity; you lose some convenience. Parking and manoeuvring in tight hallways takes a bit of shuffling due to the sheer footprint.
The Phantom 20 Stellar is hardly a ballerina, but its folding system is a bit more user-friendly. The triple-safety stem lock is slicker to operate once you know the sequence, and when folded the stem hooks to the deck, making it at least coherent to grab and shuffle around. It's still heavy enough that stairs are a workout, but it feels slightly more thought-through for trunk-hauling and storing in tighter urban flats or offices.
Where the Phantom absolutely wins is weather practicality. That IP66 rating means you can ride through proper rain without that little voice in your head whispering about warranty clauses. The Thunder 2's body and display are reasonably water-resistant, but it still feels like a machine you treat kindly in bad weather rather than a true all-weather commuter mule.
As everyday "vehicles", the Dualtron makes more sense if you mainly roll from garage to road and back, while the Apollo is that bit more liveable in real urban routines with random rain and occasional car transport.
Safety
Safety at these speeds is non-negotiable, and fortunately both scooters take it seriously - in slightly different ways.
The Thunder 2's hydraulic brakes are excellent: strong bite, predictable lever feel, and more than enough power to haul down its considerable mass from very high speeds. Add the electronic ABS, and you've got a system that, while a bit vibey under hard use, helps keep the wheels turning rather than sliding on sketchy surfaces. The chassis itself, with the stiff stem and wide tyres, feels extremely planted as long as the road isn't doing anything too weird under you.
Lighting on the Dualtron is bright and plentiful, especially in terms of side visibility. The high-mounted rear light in the footrest is a huge step up over low deck lights. The only caveat is the low-mounted front lighting: perfectly fine for being seen and for slower night cruising, but I still wouldn't call it my only light if I were doing a lot of fast night riding. Most owners fix that with an extra bar-mounted lamp.
The Phantom 20 Stellar leans harder into the "safety by design" story. The four-piston brakes are superb, with masses of modulation - you can trail-brake deep into corners without fear. The separate regen throttle gives you a second, very controllable way to bleed off speed, and using it becomes second nature frighteningly quickly.
The built-in steering damper is the unsung hero, especially above urban speeds. That extra damping in the bars means that when you hit an unexpected bump or groove at pace, the scooter tracks straight instead of wobbling. Add strong, higher-mounted front lighting and excellent side illumination, plus serious water resistance, and the Apollo feels like the more forgiving package for riders who encounter mixed conditions and lots of night or wet riding.
Both are serious vehicles that demand gear and respect. The Thunder 2 gives you a superb mechanical safety envelope; the Phantom adds more electronic and chassis polish to keep you on the safe side when things get messy.

Price & Value
Price-wise they're in the same neighbourhood, but the Thunder 2 asks for a bit more money and then unapologetically spends it on battery and sheer performance hardware. You're getting a pack that dwarfs the Apollo's, massive controllers, and a platform with a long track record in the Dualtron ecosystem. In terms of euros per kilometre of realistic hard riding, it ends up looking surprisingly sensible for something this outrageous.
The Phantom 20 Stellar undercuts the Thunder slightly and piles in value via features: steering damper, self-healing tyres, highly integrated display, app customisation, and strong water protection all included from day one. What you don't get is comparable battery size or the same ceiling of outright performance. If your use case doesn't touch that ceiling, the Apollo's package feels fair; if you intend to live near the limit regularly, the Dualtron's extra hardware is harder to ignore.
In the long run, Dualtron's parts ecosystem and resale reputation are a genuine financial advantage. Apollo is building its ecosystem fast and has improved a lot, but it doesn't yet have quite the same "you can always get parts" aura as Dualtron's worldwide network.
Service & Parts Availability
Dualtron is basically the Toyota Hilux of high-performance scooters in terms of parts and knowledge base. Need a controller, a swingarm, or some obscure cartridge two years from now? Odds are your local high-end scooter shop either has it or knows exactly where to get it. There are countless guides, community groups, and upgrade parts available. That ecosystem massively reduces long-term stress.
Apollo is far from an unknown, and their customer-facing support in Europe has improved dramatically - clear documentation, videos, and responsive channels. For core parts of the Phantom 20 Stellar, you're covered, and they clearly intend to support their flagship seriously. But because the platform is younger and more proprietary, there's a little less third-party redundancy. If you like tinkering and knowing you can always source something, Dualtron still has the edge; if you prefer emailing an official channel and getting an answer, Apollo does well.

Final Verdict - Which Should You Choose?
If you strip away the marketing and look at the riding reality, the Dualtron Thunder 2 EY4 is the more serious, more capable machine for riders who want hyper-scooter performance without compromise. The battery is in another class, the power reserves are enormous, and the platform feels like it will outlast several sets of tyres, and possibly you. It asks for respect and a bit of mechanical sympathy, but in return it gives you a scooter that feels almost absurdly overqualified for anything short of track days.
The Apollo Phantom 20 Stellar, meanwhile, is easier to live with if you prioritise comfort, refinement and all-weather capability over ultimate range and top speed bragging rights. It rides beautifully on bad roads, is more forgiving in the wet, and its electronics make the power far more approachable. As a fast, plush "super-commuter" that still thrills, it does a solid job.
My own recommendation: if you're already deep into the hobby, you know how to respect big power and you want a scooter that genuinely replaces a motorcycle for longer, faster rides, go Thunder 2 EY4 and don't look back. If you're stepping up from mid-range performance, ride plenty in the rain, and want something that feels sophisticated and friendly while still being seriously quick, the Phantom 20 Stellar will keep you happy - just be aware you're trading away some of the sheer excess the Dualtron brings to the table.
