Fast Answer for Busy Riders ⚡ (TL;DR)
If you care about how a scooter rides, feels, and ages rather than just how wild the spec sheet looks, the Dualtron Man is the more serious machine overall. Its build quality, battery, and big-wheel stability make it the better "vehicle", even if its design is niche and a bit impractical day to day.
The Nanrobot D4+ is for riders who want maximum punch for minimum money and are willing to accept rough edges, more maintenance, and a less polished feel for that privilege. If your budget is tight and you mainly want cheap thrills with some commuting on the side, the D4+ still makes a strong argument.
If you can stretch your budget and want something that feels engineered rather than assembled to a price, keep reading for why the Dualtron Man quietly pulls ahead in the long run. And if you're tempted by the D4+ "bang for buck" legend, you'll definitely want the full story before you pull the trigger.
Some scooters you buy with your head, some with your heart. Comparing the Nanrobot D4+ and the Dualtron Man is awkward because they tug in opposite directions: one shouts "value!", the other whispers "engineering experiment". Yet they land in a similar performance bracket and sit squarely in that "more than a toy, not quite a motorcycle" category.
I've put serious kilometres on both: city commutes, badly maintained bike lanes, weekend blasts, a few regrettable cobblestone shortcuts. The D4+ is the classic budget brawler - brutally fast for the money, a little unruly, and happiest when ridden hard, not babied. The Dualtron Man is more of a rolling concept bike - heavier on style and finesse, but also quietly competent as a long-range cruiser.
One sentence summary? The Nanrobot D4+ is for riders who want fireworks on a student budget. The Dualtron Man is for riders who want something different, solid, and a bit indulgent, and are willing to pay for the privilege. Let's dig into where each one shines - and where the shine rubs off.
Who Are These For, and Why Compare Them?
On paper, these two live in different tax brackets. The D4+ sits in the "affordable performance" class - roughly mid-range money for upper-mid power. The Dualtron Man is premium territory, closer to nice-used-motorbike prices than to "I'll just impulse buy it online".
Yet they compete for the same type of rider: someone who has outgrown sharing scooters and basic commuters, wants real speed, real range, and doesn't mind a bit of heft. Both are too heavy and too powerful for casual last-mile use. Both promise proper traffic-speed riding and weekend fun. And both ask you to compromise: the D4+ on refinement, the Dualtron Man on practicality and price.
If you're staring at a D4+ thinking "maybe this is my cheap ticket into serious scooters", the Man is exactly the kind of machine you'll be eyeing next - or instead - once you start reading about longevity, premium batteries and build quality.
Design & Build Quality
Park these side by side and the visual contrast is almost comical. The Nanrobot D4+ looks like a generic "extreme scooter" template: chunky stem, exposed springs, busy swingarms, cable spaghetti. It screams function over form - and sometimes function over finish. Up close, you notice the usual budget hallmarks: inconsistent weld aesthetics, hardware that wants a dab of thread-locker, and plastics that feel more "okay" than "confident". It's not awful, but it does feel built to a price, not a standard.
The Dualtron Man, in contrast, looks like a designer had fun and an engineer had nightmares. The hubless wheels are pure theatre - hollow circles that make everything else on the bike lane look prehistoric. The aluminium chassis feels dense and rigid, tolerances are tight, and the overall impression is of a machine that was designed as a whole, not as a kit of parts. You still see bolts and fasteners - this is still Minimotors, not Apple - but you sense intent rather than compromise.
In the hands, the difference is obvious. Fold the D4+ and you can feel play develop at the hinge if you don't stay on top of adjustments. The Man's folding column is overbuilt and heavy, but inspires more trust. The D4+ cockpit is typical Chinese-performance: trigger throttle, LCD pod, wires everywhere. The Man's controls are cleaner and sturdier, although still more industrial than luxury.
If your priority is "looks interesting and feels like it'll survive abuse", the Dualtron Man takes this one. The D4+ looks the part but needs more owner babysitting to stay tight and rattle-free.
Ride Comfort & Handling
Comfort is where the two philosophies really diverge. The Nanrobot D4+ uses multiple metal springs and mid-size off-road tyres to smother bad streets. It works - up to a point. On broken city tarmac, the scooter has that old-school, bouncy feel: it takes the sting out of potholes but can get a bit pogo-stick if you hit repeated bumps at speed. After a few kilometres of rough pavement, you feel more vibration than you'd like through the stem and deck. It's better than cheap commuters, but it doesn't exactly glide.
The Dualtron Man cheats: it rolls on huge tyres. Those tall pneumatic rings simply roll over stuff the D4+ has to fight. Cracks, tram tracks, ruts - you feel them, but they don't threaten your line. The hidden rubber suspension blocks do just enough to dull the high-frequency chatter without turning the ride to mush. The result is more "surfing" than "hammering". On bad asphalt, the Man is noticeably less fatiguing; your knees and wrists don't write angry letters after a long session.
Handling is a different story. The D4+ feels like a traditional scooter: narrow deck, forward-facing stance, quick steering. At higher speeds, especially on choppy surfaces, the front can get nervous. Without a steering damper, you have to stay loose and centred to avoid speed wobble creeping in. It's fun and agile, but the faster you go, the more mental bandwidth you're using to keep it tidy.
The Dualtron Man demands a sideways stance and more body English. You steer more with lean than with bar input, which feels alien for the first few rides but becomes intuitive. Straight-line stability is excellent thanks to the big wheels, but tight manoeuvres and U-turns are where you feel its limits: the turning circle is wide and low-speed agility is not its party trick. Overall, for longer rides and imperfect roads, the Man is the less tiring machine; the D4+ feels sportier but also more twitchy and raw.
Performance
Both of these can easily go faster than common sense suggests you should on something without doors. Their personalities, though, are very different.
The Nanrobot D4+ has that classic dual-motor "punch you in the chest" feel. Crack the trigger in full power and it lunges forward. It's exciting, a bit brutal, and slightly unrefined. Throttle modulation out of the box is on the touchy side; creeping at walking speed requires practice, and inexperienced riders often end up with accidental hard launches. Once rolling, it keeps pulling strongly up to proper city-traffic pace and beyond, with enough headroom that you'll probably run out of courage before it runs out of motor.
The Dualtron Man's single, big rear motor is more like a strong push than a slap. It doesn't hit as violently off the line as some dual-motor monsters, but it builds speed with a thick, insistent surge. The 60 V system does a good job of holding that character as the battery empties, so you don't get the same "half-dead" feeling toward the end of the charge that you do on cheaper setups. Top speed is in the same general ballpark as the D4+, but because you're lower and more stretched, it can feel even faster - especially when the front starts to feel light near its upper limits.
On hills, the D4+ has the advantage of twin motors yanking you upwards; it shrugs off steep urban climbs impressively, especially at the start of a charge. The Man doesn't embarrass itself - the torque is ample - but it's a cruiser, not a hill-climb champion. Where the Man claws back points is braking: the combination of regen and mechanical disc gives strong, controllable deceleration. The D4+'s hydraulic stoppers have very good outright power, but paired with that sensitive throttle and lightish front end, emergency stops require practice and respect.
In short: if you judge performance purely by how violently a scooter launches and how quickly it murders hills, the D4+ feels more dramatic. If you want a smoother, more linear shove, the Man is nicer to live with, even if it doesn't always feel as hilariously over-motorised.
Battery & Range
The gap here is not subtle. The D4+ has a decently sized pack for its price, and for most commutes you'll be fine - as long as you're realistic. Ride it the way it tempts you to (turbo, dual motors, frequent full-throttle pulls) and you're looking at solid medium-distance capability, not cross-county epics. Range drops quickly when you hammer it, and near the bottom of the pack you really feel the performance sag.
The Dualtron Man's battery, by comparison, is a proper touring tank. Double-digit-hour leisure rides at sane speeds are absolutely on the table. Even ridden "enthusiastically", it covers substantially more ground per charge than the D4+. Range anxiety basically vanishes for typical urban use; you're planning charges in days, not individual round trips.
There is, however, the charging elephant in the room. The D4+ with the stock brick is an overnight affair; adding a second charger makes it liveable for heavy daily use. The Man, with its huge LG pack, crosses from "annoying" to "unacceptable" on the standard charger - you really want the fast charger to make ownership practical. Either way, if you hate planning around charge times, neither is ideal, but the Man at least rewards you with far more riding per charge.
Efficiency wise, the D4+ burns through its energy more quickly per kilometre when ridden hard; the Man's bigger battery and better cells translate into calmer voltage behaviour and less range drama as speeds fluctuate.
Portability & Practicality
Let's not sugar-coat this: both are heavy lumps. You are not casually tossing either into a train or carrying them up narrow spiral staircases unless you are training for a strongman contest.
The Nanrobot D4+ folds into a recognisable scooter shape and, while heavy, is at least something you can deadlift briefly into a car boot. The folded footprint is reasonably compact for what it is, and the telescopic stem plus folding bars help. But every stair reminds you that those dual motors and large battery come at a cost. Move it frequently when not riding and you quickly start muttering about gym memberships.
The Dualtron Man is a different type of awkward. It's roughly as heavy, but the low, long frame and fat hollow wheels make it more like lifting a small motorcycle frame than a scooter. The folded column helps a bit with storage height, but the overall footprint remains large and ungainly. Manoeuvring it through narrow corridors or into lifts is a careful dance, not a quick shuffle.
For daily practicality, neither is a champion. If you have ground-floor storage or a garage, both are fine. If your life involves multiple flights of stairs and cramped public transport, both are frankly the wrong tool. Between the two, the D4+ is slightly more "conventionally" manageable; the Man is the one you park, lock and leave outside your office, not the one you park under your desk.
Safety
Both scooters are fast enough that safety depends more on the rider than on the hardware - but the hardware still matters.
The Nanrobot D4+ earns praise for its hydraulic brakes; power and initial bite are strong, and once dialled in, they haul the scooter down with real authority. Paired with grippy off-road tyres, straight-line braking on decent tarmac is confidence-inspiring. Where things get less rosy is high-speed stability. On stock geometry, with no steering damper, the front can develop wobbles at speeds where you really don't want surprises. Many owners wisely add dampers and tinker with tyre pressures to calm it down. Stock lighting is bright enough to be seen, but mounted low; for proper night riding you'll want a bar- or helmet-mounted light anyway.
The Dualtron Man trades textbook braking hardware for a very effective regen system plus a mechanical rear disc. Dialled up, the electronic brake does much of the work and can be modulated precisely with a bit of practice. The huge tyres help a lot: they roll through hazards that would pitch a 10-inch scooter, and the gyroscopic effect gives a reassuring straight-line feel. The flip side is that at very high speeds the front can feel floaty, and the long wheelbase plus unusual stance mean you need to actively manage weight transfer under hard braking.
In the wet, neither machine is something I'd recommend for enthusiastic riding. The D4+ has only basic splash resistance and exposed mechanicals; the Man's enclosed hubless system shrugs off splashes better, but those big tyres can aquaplane if you're careless. Lighting on the Man is typical Dualtron: lots of LEDs, decent visibility, still benefits from an auxiliary high-mounted light.
Overall, the Man feels inherently safer at moderate speeds on rough or unpredictable surfaces. The D4+ can be perfectly fine if you invest in setup (steering damper, bolt checks, cockpit tuning), but out of the box it demands more respect and attention to stay composed at its top end.

Price & Value
This is where the D4+ usually wins hearts: it delivers serious speed and dual motors for less than many single-motor commuters. If you judge value purely by "how hard it pulls per euro", it's a bargain. But once you factor in the softer stuff - build precision, component longevity, daily refinement - you start noticing where the corners were cut. Out of the box, most D4+ owners end up investing extra in things like steering dampers, better lights, thread-locker, upgraded tyres or tubes. It's still good value, but not quite the miracle deal some marketing suggests.
The Dualtron Man is almost the opposite: coldly analysed by specs alone, it looks expensive. For the same money, you can get higher-performing Dualtrons or other dual-motor machines that will embarrass it off the line. But the Man sells an experience: the unique design, the big-battery peace of mind, the carving sensation. If you want exactly that, there's no cheaper stand-in; it's a niche premium product and prices itself accordingly.
From a purely rational commuter standpoint, neither is stellar value. But if you want maximum thrills per euro, the D4+ is clearly the cheaper entry ticket. If you want something that feels like a premium object and you care about long-term battery quality, the Man justifies more of its price than you might think - as long as you actually want its weirdness.
Service & Parts Availability
Nanrobot has become a familiar name in Europe, and the D4+ is one of those scooters you can find parts for almost anywhere online. Brake pads, tyres, throttles, controller boards - the ecosystem exists, and there's a big DIY community on social platforms with guides for almost every issue. The flip side is that you do tend to need that ecosystem: regular bolt checks, occasional stem adjustments, and the odd electrical gremlin are not unheard of.
Minimotors, under the Dualtron brand, has a wide network of authorised dealers and service partners. The Dualtron Man is rarer than mainstream Dualtrons, but many parts (electronics, battery components, brake parts) are shared with the rest of the line, and official distributors generally know the platform. The hubless wheel assembly is more specialised - tyre changes and deeper issues are best handled by shops that have done it before, not your first DIY project in the living room.
In Europe, if you want easy and cheap self-service, the D4+ is more approachable. If you prefer proper dealer support and are willing to pay workshop labour rates, the Man sits in a better-supported family.

Final Verdict - Which Should You Choose?
If you strip away the marketing noise, the Nanrobot D4+ is a gateway scooter: it gives you a real taste of high power without an eye-watering price tag. But it also gives you homework - bolt checks, setup tweaks, aftermarket fixes for niggles the factory didn't fully solve. If you enjoy tinkering, want big thrills on a relatively modest budget, and accept that refinement is not its strong suit, it can be a riot. Just go in with your eyes open: this is more muscle car project than German saloon.
The Dualtron Man, quirky as it is, feels more like a finished product. The build, the battery, the way it carries speed over bad surfaces - it all points to a machine designed to last, not just impress spec sheets. It's not the fastest Dualtron, not the most practical scooter, and certainly not the cheapest way to go quickly in a straight line. But as an object to live with and ride repeatedly, it inspires more long-term confidence than the D4+. If forced to choose one to keep for several seasons of hard use, I would take the Man - and accept its oddities - over the D4+'s cheaper fireworks.
So: pick the Nanrobot D4+ if your priority is maximum power per euro and you're comfortable being your own mechanic. Pick the Dualtron Man if you want a more mature, longer-legged partner that feels engineered rather than merely assembled - and you're willing to pay for that difference, plus a little extra for the sheer sci-fi theatre.
