Monster vs Monarch: OBARTER X5 Takes On the DUALTRON Storm New EY4

Fast Answer for Busy Riders ⚡ (TL;DR)

The DUALTRON Storm New EY4 is the more complete, grown-up scooter here: better engineering, stronger real-world range, vastly nicer cockpit, and a sense of polish the OBARTER X5 simply doesn't match. It's the pick if you want a serious hyper-scooter that feels engineered rather than improvised, and you care about long-term ownership, support and refinement.

The OBARTER X5 suits riders who mainly want maximum drama per euro: huge wheels, brutal power, off-road antics and not much concern for finesse, weight or brand ecosystem. It's tempting if you want to go very fast for comparatively little money and you're handy with tools.

If you can afford it and plan to ride a lot, go Storm. If your priority is raw bang-for-buck and you're okay living with compromises, the X5 can still make you grin. Now, let's dig into where each of these beasts really shines-and where the shine wears off.

Hyper-scooters used to be unicorns. Now they're everywhere, and two names come up a lot when riders start dreaming past their commuter toys: the OBARTER X5 and the DUALTRON Storm New EY4. On paper, both promise more power than most people can sensibly use and enough battery to turn your city into a playground.

I've clocked long days on both: bumpy forest tracks on the X5 with mud on the fenders, and fast suburban runs on the Storm where traffic stops feeling like a threat and more like moving scenery. One is a budget brawler with oversized boots; the other is a pedigreed brute with manners-most of the time.

They aim at the same rider profile but take very different routes to get there. One sentence each? The OBARTER X5 is for the rider who wants maximum chaos per euro. The Storm New EY4 is for the rider who wants to go just as hard, but expects the scooter to feel like a finished product, not a project. Stay with me; the differences matter more than the spec sheets suggest.

Who Are These For, and Why Compare Them?

Both scooters live in the "hyper-scooter" class: terrifyingly quick, impractically heavy, and absolutely wasted on five-minute inner-city hops. They're built for riders who already know what they're doing and are now looking to replace a motorbike or a second car.

The OBARTER X5 comes in at a noticeably lower price, with headline specs that nip at the heels of scooters costing well over twice as much. Big power, big battery, even bigger tyres. It's marketed like a shortcut into the big leagues: Storm-ish performance without Storm money.

The Storm New EY4, meanwhile, sits firmly in premium territory. You're paying for a 72 V ecosystem, a removable battery, better cells, the fancy EY4 cockpit, and a brand with a sizeable European dealer and parts network. Same idea-"insane scooter"-but a very different execution and ownership experience.

So yes, they're competitors in the sense that someone with a "huge power, around this kind of money" budget will look at both. But they appeal to different temperaments: one to the tinkerer who likes a deal, the other to the rider who'd rather spend more once and not constantly wonder what's going to rattle loose next.

Design & Build Quality

Park them side by side and the philosophies couldn't be clearer. The OBARTER X5 is industrial brutalism with a hint of "garage prototype": chunky double stem, exposed bolts, fat 13-inch off-road tyres, plenty of metal edges. It feels solid in the hand-heavy stem, thick deck, big swing arms-but the finish is utilitarian. Paint, welds, cable routing: all perfectly acceptable, not remotely inspiring.

The DUALTRON Storm New EY4 looks and feels like someone obsessed over tolerances. The aviation-grade aluminium, sharper machining and better anodising are obvious the moment you grab the stem or press the folding collar home. The deck and rear footrest integrate neatly, the hinges feel precise rather than merely strong, and the EY4 display instantly lifts the whole cockpit into "modern vehicle" territory instead of "DIY e-project".

With the X5, you get the sense of a tank built to a price. It will take abuse, but out of the box I ended up tightening more bolts than I'd like on a brand-new machine, and the fenders don't exactly whisper longevity. On the Storm, the occasional plastic rattle is still there if you hunt for it, but as a whole it feels like a cohesive product, not a pile of parts that happen to agree on a direction.

If you're the kind of rider who notices crooked stickers and misaligned cable guides, the Dualtron will bother you a lot less over time.

Ride Comfort & Handling

Both of these are heavy, overpowered slabs of metal, but they ride very differently.

The OBARTER X5 leans hard on those oversized 13-inch tyres. They're essentially your first and second line of suspension. On broken tarmac or gravel roads, you just roll over stuff that would make smaller-wheeled scooters flinch. Coupled with a reasonably plush front hydraulic fork and a stiffish rear spring, the X5 has this slightly floaty, "mini-moto" feeling. Handling is stable rather than nimble; the big footprint likes wide arcs, not tight slaloms. At speed it feels planted, though the tall stance and long wheelbase mean you steer more with body weight than with wrist flicks.

The Storm New EY4 is the opposite: tighter, lower, more focused. Dualtron's rubber cartridge suspension is firmer, with less travel and more feedback. On clean asphalt, it's brilliant-you feel connected, carving long bends with the wide handlebars giving tons of leverage. Hit a series of deep potholes or nasty cobbles, and the front transmits more shock into your knees and wrists than the X5 would in the same situation. It's still manageable, but this is clearly tuned more for performance than plushness.

After a few kilometres of bumpy city pavements, the X5 spares your joints more; after a few kilometres of fast sweepers, the Storm feels more precise and confidence-inspiring. Think of the X5 as a big soft-tyred SUV and the Storm as a slightly stiff hot hatch-each shines on different roads.

Performance

Let's be honest: nobody buys either of these to dawdle in Eco mode.

The OBARTER X5 hits hard. Dual motors and a relatively low-cost controller setup give you that classic "ON or OFF" trigger feel. In the higher power modes, the first pull of the throttle is almost comical-rear-biased weight transfer, knobby tyres scrabbling for grip, and the scooter lunging forward with a shove that will surprise anyone migrating from mid-tier machines. It keeps pulling well into car-traffic territory, and on private roads it will confidently live in speeds that really belong on plated vehicles.

The drawback is finesse. In traffic or tight spaces, that jerky low-speed control is tiring. You can tame it somewhat in the settings, but it never turns into a smooth, progressive throttle. Braking, at least, is reassuring: the hydraulic discs and electronic assist haul the heavy chassis down with plenty of authority, though lever feel isn't quite at big-name brand level.

The Storm New EY4, despite using old-school square-wave controllers, feels like a more disciplined animal. There's even more peak torque on tap, but the power delivery is a touch more predictable, and you can fine-tune behaviour through the EY4 system in a way the X5 can't match. Off the line it will happily embarrass most cars, and it keeps shoving you forward far beyond what most riders will ever responsibly use. On steep hills, the Storm doesn't just hold speed-it actually accelerates uphill, which never stops being slightly absurd.

Braking is a clear win for the Dualtron. The NUTT hydraulic system with big rotors and strong magnetic assist feels both stronger and more controllable, letting you trail brake into corners or scrub just a bit of speed mid-bend without drama. On the X5, emergency stops are effective, but I found myself squeezing a little earlier and a little harder, simply because the feedback isn't quite as refined.

Battery & Range

On paper, both batteries are "massive". In practice, one is cleverly executed, the other is... large.

The OBARTER X5's pack gives you serious energy capacity for the money. Ridden hard-full-throttle blasts, hills, off-road-it will still cover a healthy distance before you start watching the voltage nervously. Back off into more sensible speeds and you can stretch it well beyond what most daily commuters will ever need. The downside is charging: with the included slow charger, you're basically locking the scooter to the wall overnight and then some. Owners almost universally end up buying faster chargers or using dual ports to make it tolerable.

The Storm's LG pack is not just big, it's high-quality. Real-world range, at mixed speeds and with a reasonably heavy rider, comfortably sits a tier above the X5. You can ride enthusiastically and still complete big loops or long suburban commutes without constantly thinking about the next outlet. More importantly, the fast charger that comes in the box turns the huge battery from an anchor into an asset: long ride on Saturday, plug it in over lunch or afternoon, and you can head back out by evening.

Voltage sag behaviour is also better on the Dualtron. The X5 starts to feel a bit lethargic once the battery drops past the mid-point; still rideable, but the top-end rush softens noticeably. The Storm keeps its punch deeper into the pack before finally admitting it needs a rest.

Portability & Practicality

Let's not pretend: both of these are anchors with wheels. But there are degrees of misery.

The OBARTER X5 is brutally heavy, and it feels every gram of it. The long wheelbase and gigantic tyres make manoeuvring in tight hallways or narrow storage spaces a bit of a dance. Folding the stem is straightforward, but once folded, you're still left with a very long, very awkward object. Carrying it up stairs solo is theoretically possible; practically, it's how you learn what your back can't do.

The Storm New EY4 is hardly a featherweight either, but the design mitigates things slightly. The folding mechanism is more confidence-inspiring, the handlebars tuck in neatly, and most importantly, the battery comes out. That one detail completely changes daily life if you live upstairs or don't have a socket in the garage. You still won't be slinging the bare chassis over your shoulder, but separating "heavy thing to lock downstairs" from "slightly less heavy thing to charge inside" is a game-changer.

In day-to-day use, both work best as vehicle replacements, not baggage. You park them like motorbikes. For suburban runs, shopping, and cross-town commutes, they're brilliant. For multi-modal trips with trains and buses? Absolutely not-even the Storm's clever battery trick can't turn it into a last-mile toy.

Safety

At these performance levels, safety is less "nice feature" and more "will I regret this decision at 60 km/h?"

The OBARTER X5 checks the basic boxes: hydraulic brakes, E-ABS, big tyres that calm down potholes, and a very bright twin-headlight setup that actually lets you see the road ahead. The huge rolling diameter helps stability, and once you get comfortable with the throttle, straight-line riding feels secure. Turn signals are present but small and low, and I wouldn't rely on them alone to advertise my intentions in busy traffic.

The Storm New EY4 takes everything a step further. Braking, as mentioned, is a notch up: more powerful, more consistent, and more communicative. The high-output headlights turn night riding from "I hope that's not a pothole" into "I can actually see what I'm doing", and the full lighting suite (indicators, brake lights, side RGB) makes you visible from almost any angle. The wider handlebars and reinforced stem architecture also mean far fewer white-knuckle moments at high speed; it just feels calmer when things get fast or gusty.

Neither scooter will save you from bad decisions, but the Storm gives you more tools and more composure to avoid making them in the first place.

Price & Value

This is where the OBARTER X5 tries to land the knockout punch. For significantly less money, you're getting a big battery, big motors, and big wheels. On a pure spreadsheet "specs per euro" comparison, it looks heroic. If you want maximum speed and torque for the least cash, it's hard to ignore.

But value isn't just about first purchase. The Dualtron Storm New EY4 costs a lot more, yes-but you're paying for better cells, a refined chassis, support from a long-established brand, easier access to spares, and a scooter that feels like it was designed as a whole, instead of around a "how much motor can we bolt on?" question. It's also likely to hold its value better if you decide to sell later.

If your budget ceiling sits closer to the X5 and you're comfortable fettling and upgrading, it offers aggressive value. If you're thinking in terms of multi-year ownership, daily use, and minimum hassle, the extra you spend on the Storm makes more sense than the raw euro difference suggests.

Service & Parts Availability

With OBARTER, your real-world support depends heavily on the retailer you buy from. The brand itself sits in that slightly anonymous Chinese OEM zone: decent hardware, but warranty and parts can be patchy, especially a year or two down the line. The good news is that many components are generic-standard brake parts, common tyre sizes (if not common diameters), off-the-shelf controllers-so DIYers can usually keep them alive. But you need to be willing to hunt for parts and occasionally wait for shipping from overseas.

Dualtron, and specifically the Storm series, enjoy much better coverage in Europe. There are established distributors, service centres, and a thriving aftermarket. Need a new swing arm, an exact replacement for a random bolt, or an upgraded brake kit? Odds are someone stocks it locally, and a dozen people on a forum have already written a guide. That doesn't mean repairs are cheap-but they are possible, and that matters when you're sitting on a machine this powerful.

Final Verdict - Which Should You Choose?

If you forced me to live with one of these for a year as my only powered transport, I'd take the DUALTRON Storm New EY4 without hesitating. It's not perfect-stiff over bad roads, still a bit old-school in throttle feel-but it behaves like a mature, engineered product. The removable LG battery solves real-world problems, the brakes and cockpit belong on a modern machine, and the brand's ecosystem makes long-term ownership markedly less stressful.

The OBARTER X5 absolutely has its audience. If your budget caps around its price and you crave serious power, big-wheel stability and off-road antics, it will deliver genuine thrills. But you need to go in with eyes open: you're trading finish, support and refinement for those headline specs. Expect to tinker, tighten, tweak, and maybe forgive a few rough edges along the way.

So: riders who want a hyper-scooter as a real vehicle-commuting, long rides, predictable behaviour day after day-should stretch to the Storm if they possibly can. Riders who mainly want a big, rowdy toy with outrageous performance per euro, and who don't mind getting their hands dirty, will still have a great time with the X5. Just don't confuse "cheap for what it does" with "actually cheap to live with".

These metrics strip the scooters down to pure maths. Price-per-Wh and price-per-km/h show how cheaply each euro buys you battery and top speed; efficiency and weight-per-Wh indicate how smartly the mass and energy are used. Ratios like power-to-speed and weight-to-power expose how much punch you get relative to the claimed top end, while charging speed simply tells you how long you're tethered to a socket. None of this captures feel or build quality-but it's a useful lens if you enjoy spreadsheet racing.

Based on the scoring, the DUALTRON Storm New EY4 is our overall winner. In the end, the Storm New EY4 simply feels like the scooter you trust: it hits harder, goes further and, crucially, behaves itself when the road or weather turn nasty. The OBARTER X5 can absolutely thrill, and its big-wheel bravado at its price is entertaining, but it never quite shakes the sense that you're riding a good deal rather than a great machine. If you want your hyper-scooter to be a daily partner rather than an occasional party trick, the Dualtron is the one that will keep you happy long after the novelty of brutal acceleration wears off. The X5 will still make you laugh every time you pin the throttle-you just have to accept that you're signing up for a little more compromise and a little more spanner time.

That's our verdict when we try to stay objective – but hey, riding is mostly about emotions anyway, so pick the one that will make you look forward to your commute every single day.
