Fast Answer for Busy Riders ⚡ (TL;DR)
The NIU KQi2 Pro is the better overall commuter: it feels more refined, better put together, and delivers a calmer, more confidence-inspiring ride for everyday city use, especially if you care about reliability and low maintenance more than raw punch. The Razor C45 hits harder off the line and runs a bit faster, but its harsher rear ride, braking feel, and price make it harder to recommend as a primary daily tool rather than an occasional runabout.
Choose the NIU if your priority is a solid, grown-up scooter that just works and doesn't rattle itself (or you) to pieces. Pick the Razor C45 if you really want that extra top speed, love the big front wheel stability, and ride mostly on smooth, flat surfaces where its weaknesses don't show as much.
If you want to know where these two secretly shine and where they quietly fall apart, keep reading - the details matter here.
Electric scooters have grown up. What used to be flimsy toys are now serious alternatives to buses, cars, and crowded trains. In this grown-up world, the NIU KQi2 Pro and Razor C45 both promise to be your daily workhorse - just with very different ideas of what "good" looks like.
I've put real kilometres into both: office commutes, late-evening grocery runs, and the usual "I'll just quickly test this hill and end up riding for half an hour" sessions. One feels like it was engineered by people who design vehicles. The other feels like it was drawn up by people who've sold scooters for decades - but are still catching up to what modern commuters expect.
The NIU KQi2 Pro is for riders who want a smart, stable, low-drama commuter. The Razor C45 is for those tempted by extra speed and a big, reassuring front wheel, and who are willing to live with some compromises in comfort and refinement. Let's dig into how they actually stack up in the real world.
Who Are These For, and Why Compare Them?
Both scooters sit in that "serious but still vaguely affordable" commuter bracket: not supermarket specials, not monster dual-motor rockets either. They aim at adults who want a daily vehicle rather than a weekend toy.
The NIU KQi2 Pro lives a bit closer to the budget end, undercutting many big-name rivals, but still trying to feel premium in build and design. Think: sensible commuter, shorter urban trips, mostly flat to moderately hilly cities, rider who'd rather have reliability than bragging rights.
The Razor C45, on paper, stretches into the next tier: more motor power, higher top speed, chunkier frame, and a brand name that a lot of people grew up with. It's pitched as the "proper" grown-up Razor that can actually keep up with bike-lane traffic.
They're natural rivals because if you have a mid-range budget and want a single-motor commuter, these two will absolutely land on the same shortlist - one promising refinement and smart engineering, the other louder numbers and that nostalgic Razor logo.
Design & Build Quality
Park them side by side and you instantly see the difference in design philosophy.
The NIU KQi2 Pro looks like a modern consumer electronics product that happens to have wheels. Clean lines, almost no visible cabling, a slick stem with an integrated display and that signature halo headlight. The aluminium frame feels dense and monolithic; when you pick it up, there are no creaks, no flex at the neck, nothing that makes you wince.
The Razor C45, by contrast, is pure industrial. Steel frame, big welds, big front wheel, dark colours - more utility than beauty. The folding mechanism feels sturdy enough, and the frame itself does give off that "you can abuse me" vibe. But it doesn't have the same sense of tight integration. The rear fender and some joints are more prone to develop rattles once you introduce them to less-than-perfect tarmac.
In the hands, the NIU gives that tidy, finished impression: smooth edges, tidy plastics, well-routed cables, and a neat, flush dashboard. The Razor feels solid but more old-school - like a tough tool, not a refined product. That's not automatically bad, but if you're used to modern consumer tech, the KQi2 simply feels more sorted.
Overall, both are sturdy enough, but if build precision and perceived quality matter, the NIU is clearly ahead. The Razor's big front wheel is its visual party trick; the NIU's trick is looking like it costs more than it does.
Ride Comfort & Handling
This is where their personalities really show.
The NIU KQi2 Pro runs on large tubeless air tyres and no suspension. Normally, that "no suspension" line would be the start of a rant, but the tyre choice and chassis geometry save it. On typical city asphalt, paving stones, and the odd imperfect bike lane, the ride is surprisingly civilised. The long, low deck and wide handlebars calm everything down; it feels planted rather than nervous. After a few kilometres you stop thinking about the scooter and just ride.
Hit truly bad cobblestones or cratered back streets and, yes, your knees immediately remember there are no springs. You can compensate with a bit of "active" riding - unlocked knees, weight shift - but this is not a scooter for off-road shortcuts.
The Razor C45 is a tale of two halves. The big front pneumatic tyre is fantastic: it steamrolls over cracks and rough patches, and the steering stays calm even at higher speeds. Your hands and upper body get the benefit. But then the rear end arrives. That solid rear tyre and steel frame feed a lot of vibration straight into your feet and legs. On smooth bike paths, the ride is fine. After a few kilometres on broken concrete, you start wondering if your fillings are still in place.
In corners, the NIU's wide bar and balanced chassis make it the more confidence-inspiring machine. The Razor's big front wheel actually helps a lot with stability when leaning into turns, but the mismatched grip and feel front-to-rear can be slightly odd until you're used to it: the front says "go on, it's fine", the rear replies "I'll let you know later".
For everyday city comfort, the NIU is the calmer, more predictable ride. The Razor gives you that bicycle-ish stability up front but compromises rear comfort enough that rougher cities will expose it fast.
Performance
Let's talk about how they actually move, not just what the spec sheets brag about.
The NIU KQi2 Pro, with its higher-voltage system and rear motor, feels more eager than its rated power suggests. Acceleration is smooth rather than dramatic; it builds speed in a controlled, linear way that's pleasant in traffic. No violent surges, no jerky throttle. You can confidently feed in power mid-turn without worrying about the front unweighting and slipping - rear-wheel drive does its job.
Top speed sits in that "sensible commuter" band. Fast enough to cover ground and mix with bike traffic, slow enough that you don't constantly feel like you're one pothole away from becoming a YouTube clip. It holds speed reasonably well as the battery empties; you don't get that depressing slump halfway home where everything suddenly turns into eco mode whether you like it or not.
The Razor C45 is the more energetic sibling. The stronger motor and "Sport" mode give noticeably punchier acceleration; it feels keener off the line and you reach its higher top speed quicker. On an empty path in Sport mode, it genuinely feels lively. Combined with the big front wheel, high-speed stability is actually quite good in a straight line - wind noise goes up, but the steering doesn't get squirrely.
However, two things take the shine off. First, the braking. On the NIU, the combination of front drum and regen feels very predictable. It doesn't have track-bike bite, but it's consistent and balanced; you quickly learn what a full handful of lever translates to on the road. On the Razor C45, the disc plus regen combo can feel a bit underwhelming when you really need to slow from top speed; you end up braking earlier than you'd like, just in case. At city pace that's a quirk, at full tilt it's something you have to respect.
Second, hills. The NIU's higher-voltage system helps it punch above its nominal rating on typical urban inclines, but heavy riders in very hilly areas will find its limit. The Razor's extra motor grunt does help on milder hills, but it's far from a hill-climbing monster; steeper gradients will drag it down noticeably, particularly with heavier riders.
In simple terms: NIU is the smooth, measured commuter that always feels under control. Razor is the more spirited option with a genuine speed edge - but you pay for that in braking feel and rear-end composure.
Battery & Range
Manufacturers' range claims are written in a universe where riders are featherweight, the world is absolutely flat, and nobody ever uses top speed. Back on Earth, both scooters sit in a similar "commuter-friendly but not touring" range bracket.
The NIU KQi2 Pro's battery, managed by NIU's mature BMS tech, delivers a very usable real-world range for daily commuting - enough for most people to do a there-and-back urban trip with some detours and still have something left in the tank. Ride it hard at full speed and you'll naturally see that shrink, but efficiency is decent; the 48 V system helps keep performance relatively consistent until you're fairly low.
The Razor C45 claims slightly more on paper, and with its motor and pack size that's not completely unrealistic - in gentle modes, on flat ground, ridden sensibly. In the real world, mix of modes with some Sport thrown in, you're looking at a similar or only slightly longer usable range than the NIU. Ride it like a hooligan in Sport mode all the time and, unsurprisingly, the battery goes down quicker than you'd hope.
Charging is an overnight-or-workday thing for both. The NIU takes a bit longer to refill from empty, which is kinder to the cells but requires a tiny bit more discipline if you're the "I'll plug it in later... maybe" type. The Razor is a touch quicker, but we're not talking game-changing fast-charge territory here.
Range anxiety? On the NIU, you learn its limits quickly and it's predictable; the smart BMS and conservative claims help. On the Razor, range is adequate, but some community reports about battery longevity over a year or two do raise an eyebrow if you're thinking long term.
Portability & Practicality
On the scales, both are in the same "you can carry it, but you won't enjoy it on the fourth flight of stairs" class.
The NIU KQi2 Pro is no featherweight. Carrying it up a short set of stairs or into a car boot is fine, but anything more frequent becomes gym-session territory. The folding mechanism, though, is excellent: quick, secure, and confidence-inspiring. Once folded, it locks neatly to the rear, and the balance is good enough that carrying it a short distance doesn't feel like wrestling a dead animal.
The Razor C45 is marginally lighter on paper but doesn't feel meaningfully easier to lug around, partly because of the bulky front wheel and steel frame. Folded, it's a bit more awkward in shape - long wheelbase and overbuilt front end mean it takes up slightly more visual and physical space. Under a desk? Possible. On a crowded train at rush hour? You'll be very aware of how much scooter you're holding.
In daily life, the NIU wins on "liveability". The clean design makes it easier to stash in offices or cafés without looking like you've brought a budget motorbike inside. Its kickstand is chunky and stable, and the app adds genuinely useful day-to-day touches like motor locking and regen tuning.
The Razor C45 also has an app, with a decent amount of tweakability and data, but the overall package feels more like a heavy device you accommodate rather than something that gracefully fits around your routine.
Safety
Safety isn't just about brakes and lights; it's also about how the scooter behaves underneath you when things go wrong.
The NIU KQi2 Pro nails some fundamentals. That halo headlight isn't just a stylish ring; it throws a proper, usable beam on the road without blinding everyone in front of you. The rear light is bright and responsive, and the overall visibility package is well thought-out. Crucially, the wide handlebar and low, stable deck give you a lot of control, even for new riders. The drum-plus-regen braking setup is low-maintenance and very consistent in all weathers - there's a reason you see drum brakes on serious commuter machines.
The Razor C45 doesn't completely fumble safety, but it's more of a mixed story. The high-mounted headlight and brake-activated rear light do their job, and the big front wheel does wonders for stability over sketchy surfaces and at higher speed. That UL battery certification is a nice reassurance if you've been reading too many thermal runaway horror stories.
But braking performance relative to its speed is where it feels a bit behind. The rear disc plus regen arrangement works, yet several riders - myself included - find you have to plan harder stops earlier than you'd like from top speed. Combine that with the harsher rear ride (which can unsettle the chassis when braking on bad surfaces), and you have to ride with slightly more margin.
Both scooters use kick-to-start by default, which is safer for beginners and pedestrians alike, even if experienced riders grumble about it. On balance, the NIU feels like it's been engineered first and foremost as a safe commuter; the Razor feels like a beefed-up toy that's mostly, but not impeccably, adapted to commuter speeds.

Price & Value
This is where the NIU quietly pulls a knife in a gunfight.
The KQi2 Pro comes in significantly cheaper while delivering a very grown-up experience: mature electronics, thoughtful design, solid build, and a long warranty by scooter standards. It doesn't try to be the fastest; it tries to be the one that still works properly in two years. For a commuter who just wants a dependable tool, that's where value actually lives.
The Razor C45 costs clearly more at typical retail. You do get a stronger motor, higher top speed, a big front tyre, a steel frame, and the comfort blanket of a legacy brand name. The problem is the rest of the package doesn't always feel like it justifies the price gap: the ride is less balanced, braking is less confidence-inspiring, and some reliability stories around batteries and rattles don't scream "pay extra". If you catch it heavily discounted, the equation improves dramatically; at full price, it's a tougher sell.
Service & Parts Availability
Both brands are established, which is refreshing in a sea of anonymous white-label scooters.
NIU operates like a proper vehicle manufacturer: dealer networks in many European cities, established spare parts channels, and a track record from selling huge numbers of mopeds. For a scooter at this price point, having that kind of backbone behind it is rare. Getting a controller, brake parts or a new tyre is not an archaeological expedition.
Razor, meanwhile, has its roots in mass retail, and that shows in parts availability and documentation. You can usually find exploded diagrams, part numbers, and at least some spares without too much pain. Support is reasonably responsive, particularly in larger markets. In Europe, though, the support experience can vary more depending on country and retailer.
Between the two, NIU feels more like a "vehicle ecosystem" you're buying into; Razor feels like a known consumer brand that happens to make this scooter. Both are better than no-name brands, but NIU has the edge in long-term, Europe-centric support.

Final Verdict - Which Should You Choose?
If you stripped the logos off both scooters and asked me which one I'd want to live with every day, it would be the NIU KQi2 Pro. It isn't glamorous, it isn't fast in a way that will impress your friends, but it feels like a deliberately engineered commuter: stable, quiet, predictable, and backed by a serious EV company. For most city riders, that's exactly what you actually need.
The Razor C45 has its charms. That strong motor and higher speed do feel good on an open stretch, and the big front wheel genuinely boosts confidence where many scooters get twitchy. If your routes are mostly smooth, flat and you can grab it on sale, it can be a fun, slightly more aggressive option - especially if the Razor name gives you peace of mind.
But viewed coldly as a transport tool, the NIU gives you better value, a more polished ride, and fewer compromises for everyday use. Unless you're specifically chasing that extra top speed and front-wheel stability, the smarter money - and the calmer commute - sit firmly with the KQi2 Pro.
