Fast Answer for Busy Riders ⚡ (TL;DR)
The NIU KQi3 MAX is the stronger all-round commuter: it goes noticeably further, feels more refined, and offers better safety tech and finish, making it the more confidence-inspiring daily vehicle. The Razor C45 fights back with a lower price, a big, stable front wheel and a slightly lighter, more compact package, but its rough rear ride and weaker range hold it back as a serious primary commuter.
Pick the NIU if you want something that genuinely replaces public transport or short car trips. Choose the Razor C45 if your rides are short, your roads are smooth, and you mainly want a sturdy, brand-name scooter that doesn't hurt the wallet too much. Both will move you - but only one really feels built for the long haul.
Read on if you want the full, road-tested story before you spend your money.
There's something oddly satisfying about comparing these two. On one side, the NIU KQi3 MAX: the "grown-up EV company" trying to turn scooter commuting into a serious transport alternative. On the other, the Razor C45: the childhood legend that stopped being a toy, put on a dark jacket and declared it was ready for rush hour.
I've put real kilometres on both - from boring office runs to deliberately sadistic cobblestone detours - and they answer the same question in very different ways: "What should a mid-priced commuter scooter actually be?" The NIU leans into refinement and range; the Razor leans into steel, nostalgia, and a very large front wheel.
If you're torn between them, this comparison will walk you through how they ride, what they're like to live with, and which corners each one cuts to hit its price. Spoiler: both have compromises, but one makes far more sense as your daily workhorse.
Who Are These For, and Why Compare Them?
Both scooters sit in that awkward middle ground where you're spending proper money, but you're not buying a monster dual-motor machine. They target adults who want to commute at around bicycle speeds, not drag race, and who care about reliability more than Instagram flexing.
The NIU KQi3 MAX clearly aims to be a "car replacement for the city": longish commutes, heavier riders, mixed terrain, and riders who actually notice things like brake feel and lighting. The Razor C45 feels more like a "serious upgrade from a toy scooter": solidly built, decent speed for the money, but with a stronger focus on price and familiarity than on outright capability.
They compete because on paper they look surprisingly similar: similar motor rating, similar top speed, similar feature set. In reality, the way they deliver that performance - and for how long - is where the differences really start to matter.
Design & Build Quality
Park them side by side and they tell very different stories. The NIU looks like an urban EV that accidentally shrank in the wash: clean, cohesive lines, a thick, rigid stem, wide deck, and that signature halo headlight which screams "designed by someone who's seen a car before". It feels dense and well-finished - the kind of scooter you're not afraid to lock up outside a nice office.
The Razor C45, by contrast, feels more industrial. Steel frame, visible welds, and that slightly odd "big front, small back" wheel stance. It's practical more than pretty. Nothing about it screams cheap, but nothing screams premium either - it's a tool first, object of desire second. Touch the frame and you get that cold, heavy-steel solidity; tap the NIU's frame and you get robust aluminium that feels tighter and better resolved.
On the NIU, tolerances are generally excellent: the folding joint locks in with almost no play, cables are routed neatly, and there's very little in the way of panel rattle. The Razor's latch is secure but less sophisticated, and while it feels stout out of the box, the rear section and fender can develop little rattles once you start feeding it rough pavement on a regular basis.
Ergonomically, NIU gives you a wider deck and noticeably broader bars, which immediately feels more like a "vehicle stance" than a toy stance. The C45's deck is usable but narrower; big-footed riders end up in a more cramped, scooter-classic "one foot behind the other" pose. The handlebars themselves are comfortable on both, but the NIU's extra width pays off once the speed climbs.
Ride Comfort & Handling
Neither of these scooters has suspension, and both pretend their tyres are good enough to compensate. How close they get to that fantasy varies a lot.
The NIU rolls on fat, mid-sized pneumatic tyres front and rear. They're wide, tubeless and slightly "balloon-like", so on half-decent tarmac the ride is pleasantly plush for a rigid frame. You still feel expansion joints and sharp edges, but your knees aren't filing a complaint after a few kilometres. The wide deck and handlebars give you real leverage: a relaxed, shoulder-width stance and predictable steering. In quick direction changes, it feels stable rather than nervous.
The Razor's comfort is a split personality. The huge front pneumatic wheel is lovely: it swallows bumps, ignores small potholes that would completely unsettle smaller wheels, and feels reassuringly "gyroscopic" at speed. Then the rear hits the same imperfection and reminds you it's a solid tyre bolted to a steel frame. On a fresh bike lane, the C45 glides. On patched asphalt or light cobbles, the rear starts chattering and you instinctively unweight your back foot over every manhole cover.
Handling follows the same theme. At cruising speeds, both track straight and feel composed. The NIU's wider bar and more neutral front-rear geometry make it calm and predictable when carving around pedestrians or potholes. The Razor is very stable in a straight line thanks to that big front wheel, but you're more aware of the stiff rear when you tip it into tighter turns - it's not skittish, just less "joined-up" than the NIU.
Do either cope well with truly bad surfaces? Not really. On several kilometres of broken city sidewalk, the NIU keeps your fillings in place but your legs do noticeable work. The Razor's rear end, on the same route, goes from "noticeable" to "I'm going to choose another street tomorrow".
Performance
Both scooters quote a similar motor rating on paper and both drive from the rear wheel, but they feel quite different once you're actually standing on them.
The NIU's higher-voltage system gives its motor a little extra shove. In its sportiest mode, it doesn't catapult you forward, but the pull is satisfyingly linear and stronger than the numbers suggest. It gets up to its capped commuter speeds with a purposeful surge rather than a laboured build-up, and, importantly, it tends to hold that pace even as the battery dips under half. Long city avenues at full allowed speed feel easy rather than forced.
The Razor C45's motor has decent punch off the line, especially at lower speeds. It feels lively in the first few metres - more "zippy" than torquey - and in Sport Mode it will eventually wind up to roughly the same velocity as the NIU's typical top. But once you're there, it feels like it's working harder. On mild inclines, you notice the NIU shrugging and the Razor negotiating.
Climbing is where the difference really shows. On repeated medium hills, the NIU maintains a respectable pace with heavier riders and doesn't embarrass itself. You lose a bit of speed, but you still feel like you're riding, not pushing. The C45 will get you up the same slopes, but with slower cresting and more obvious power fade when the battery isn't fresh. Steeper city streets quickly become a "take a run-up and hope" exercise on the Razor, while the NIU just grinds them out.
Braking confidence is another split. The NIU's dual discs plus adjustable regen give it a surprisingly serious stopping feel for a single-motor commuter. Squeeze the levers hard from full speed and it scrubs speed quickly but stays composed; you can feel the regen biting and the mechanical brakes backing it up. The Razor's single rear disc plus regen will stop you, but you need more distance and more planning. At its top mode, you start braking earlier than your instincts would like until you recalibrate.
Both use kick-to-start. NIU's implementation can feel a bit fussy at first - you need a firm shove and a heartbeat of patience before the motor wakes up. The Razor's system is less fussy but still not instant. Once moving, the NIU's throttle mapping feels more polished: predictable, smooth, and easy to feather through traffic. The C45's thumb throttle is fine, just slightly more "basic" in feel.
Battery & Range
This is where the contest becomes rather one-sided. NIU stuffed a much larger battery into the KQi3 MAX, and you feel it in daily life. On mixed riding - a lot of sport mode, some eco when you're stuck behind cyclists - it realistically delivers commutes that stretch over multiple days for most city users. With moderate self-control, you can leave the charger at home for a there-and-back day that would have a smaller-pack scooter sweating.
The Razor C45's pack is honest but modest. In calm riding and its middle mode, it'll handle a typical urban round trip comfortably. Push it in Sport Mode and you watch the bars drop much more quickly. For riders with short, flat routes, that's fine; for anyone dreaming of long cross-town rides, the gap versus the NIU becomes glaring.
Range anxiety tells the story best: on the NIU, I simply stopped thinking about battery unless I'd been reckless for several days in a row. On the Razor, I found myself glancing at the display more often, especially after a spirited blast or a few hills. It's not a toy-level range, but it's firmly "commuter with limits" rather than "mini tourer".
Charging times are both in the overnight camp. The NIU takes a bit longer to refill from empty, but given the extra energy stored, its average charging speed is actually quite healthy. The Razor finishes sooner, but only because there's less to pour in. In practice, you plug both in after work and they're ready long before you are the next morning.
Portability & Practicality
Neither of these is a featherweight "throw it on your shoulder and jog up four floors" scooter, but they sit in different parts of the same band.
The Razor C45 undercuts the NIU by a few kilos and you do feel that when lifting. Carrying it up one or two flights of stairs is doable without questioning your life choices, and the steel frame gives you obvious grab points. Folded, the big front wheel does make the package a bit long-nosed, but for car boots and train vestibules it's manageable. It's still heavier than many simpler commuters with similar range, which makes the weight feel a bit less justified.
The NIU is the heavier of the two and feels it. Lifting it regularly is a small workout, and the thick stem isn't the friendliest thing to grip if you have smaller hands. But that mass also brings a sense of solidity on the road. Folded, it's more compact lengthwise than the Razor but wider thanks to its bars, so it takes up more sideways space under a desk or on a crowded train.
For "roll it to the lift, fold it at the office and forget about it", both are fine. For "I live on the fifth floor, no lift, and my landlord hates bikes in the hallway", neither is ideal - but the NIU will make you swear slightly more on the stairs.
Safety
On safety, NIU clearly approached the KQi3 MAX like a small vehicle; Razor approached the C45 like a robust scooter.
The NIU's halo headlight is simply in another league for visibility. It's bright, well-aimed and highly conspicuous to other road users. Paired with self-healing tubeless tyres and dual discs, it gives you a rare combination in this class: good grip, strong braking and outstanding "see and be seen" performance. The wide cockpit and planted geometry further reduce the feeling of sketchiness at top speed.
The Razor's safety story leans on that big front wheel and UL electrical certification. The large tyre genuinely helps with stability and hazard avoidance - it's far less likely to disappear into a pothole - and the UL certification is reassuring in a world of questionable batteries. The lighting is acceptable and functional, but not standout. The rear brake light is a welcome detail, yet the overall package doesn't quite inspire the same high-speed confidence as the NIU.
Grip-wise, pneumatic front plus solid rear on the Razor is a compromise: predictable up front, a bit harsher and less communicative at the back. NIU's dual pneumatic setup gives you a more uniform feedback loop, especially in the wet. Add in the stronger braking system and NIU ends up the more confidence-inspiring scooter when you need to ask a lot from it.

Price & Value
Now to the wallet. The Razor C45 comes in noticeably cheaper at typical retail, and even more so when it's on sale - which it often is. At those discounted prices, it's a tempting proposition: solid brand, respectable speed, basic app features, and a very reassuring front wheel, all for what you'd expect to pay for a more anonymous budget scooter.
The NIU asks for a chunk more cash, nudging into the upper mid-range of commuter pricing. In return you get a significantly larger battery, more sophisticated brakes, better lighting, more refined construction, and a generally more "grown-up" riding experience. Cost per kilometre over the life of the scooter starts to tilt in NIU's favour once you factor in its range and component quality.
If your budget has a hard ceiling and you mainly ride short, smooth routes, the Razor's value story is serviceable - especially discounted. But if you're already spending serious money and care about long-term satisfaction rather than just initial outlay, the NIU gives you more scooter per euro in ways you actually feel every day.
Service & Parts Availability
Both brands are established players, which already puts them ahead of the random alphabet soup scooters that vanish from marketplaces every few months.
NIU brings the weight of a proper EV manufacturer. In much of Europe you'll find official dealers, authorised repair partners and a steady supply of genuine parts. Firmware updates and diagnostics come via the app; if something electronic misbehaves, there's usually a pathway to a solution that doesn't involve obscure forums and soldering irons.
Razor's strength is ubiquity. They've been around for decades, they sell through big retail channels, and they're used to supplying spares for years after release. For mechanical bits - levers, tyres, basic frame parts - you're unlikely to be left stranded. Where they're not quite as strong as NIU is in the more sophisticated smart-vehicle ecosystem; you're dealing with a solid consumer product, not a mini Tesla.
In practice, both are serviceable in Europe, but NIU feels a step closer to the "proper vehicle" side of the spectrum, while Razor feels more like a well-supported consumer gadget.

Final Verdict - Which Should You Choose?
Put simply, the NIU KQi3 MAX feels like a purpose-built commuter vehicle; the Razor C45 feels like a tough, slightly compromised scooter that grew up but not all the way.
If your rides are more than a few kilometres, involve hills, or you care about lighting, braking, and overall polish, the NIU is the safer and frankly more pleasant choice. It has the legs, the poise and the finish to justify its higher price, even if it does make your biceps work on the stairs.
The Razor C45 makes sense for shorter, smoother, budget-aware use: flat campus hops, last-mile from a park-and-ride, or occasional urban errands where you value a strong brand and a big, forgiving front wheel more than long range or luxury. Just go in knowing its limits - especially at the rear end and at higher speeds.
If I had to live with one of these as my main urban transport, it would be the NIU KQi3 MAX without much hesitation. The Razor C45 is like that old friend who still knows how to have fun, but the NIU is the one you actually trust with your daily commute.

These metrics strip away riding feel and look purely at maths: how much range and speed you get per euro, per kilogram, per watt. Price-per-Wh and price-per-speed show how cheaply each scooter buys you basic capability. Weight-based metrics highlight which one uses its mass more efficiently. Wh per km shows real-world energy efficiency. Power-to-speed indicates how "over-motored" a scooter is for its top speed, while weight-to-power hints at how lively it feels. Average charging speed is a simple way of saying how quickly a completely empty pack is refilled.
