Fast Answer for Busy Riders ⚡ (TL;DR)
The KuKirin S1 Max edges out as the more capable all-round commuter on paper, mainly thanks to its noticeably bigger battery, longer real-world range, and proper suspension at a lower price. If you want maximum kilometres per euro and don't mind a firmer, more "budget scooter" feel, the S1 Max is the rational choice.
The Razor C35 fights back with a much more confidence-inspiring big front wheel, a sturdier-feeling frame, and a simpler, more honest design that suits cautious riders and scooter newcomers. If comfort over bad city surfaces and brand reassurance matter more to you than raw numbers, the C35 can still be the better everyday partner.
Both have clear compromises, so the "winner" depends a lot on your roads and your tolerance for vibrations and quirks. Keep reading - the differences only really show when you imagine living with each scooter day in, day out.
Electric scooters in this price bracket are all about compromise, and the Razor C35 and KuKirin S1 Max represent two very different answers to the same commuter question. One leans on a big, confidence-boosting front wheel and a beefy steel frame; the other plays the numbers game with more battery, suspension and a sharp price.
I've put serious kilometres on both: early morning commutes on damp bike lanes, weekend errands over broken pavements, and the usual "why did I choose this shortcut?" cobblestone experiments. They look like they live in the same category, but they don't ride like twins.
If you're trying to decide between "big wheel, simple and sturdy" and "more range, more features, less money", this comparison will save you a few weeks of reading forum threads. Let's dig in.
Who Are These For, and Why Compare Them?
Both scooters sit in the budget-to-lower-mid commuter segment: affordable enough not to feel like a life decision, but serious enough to replace a bus pass if your city isn't made of hills and craters.
The Razor C35 is aimed at the cautious or first-time adult rider who wants stability, a known brand and a scooter that feels more "tool" than "gadget". Think shorter, predictable urban commutes, with plenty of rough pavements and the odd dodgy curb.
The KuKirin S1 Max is for the value hunter: someone who wants a lightweight, chuck-it-under-the-desk scooter with better-than-average range for the money, and doesn't mind that it feels a bit more budget in places. Perfect for multi-modal commuters bouncing between trains, lifts and smooth cycle paths.
Price-wise they live close enough to compete, but the way they achieve that price is very different. Same mission (cheap, practical city mobility), very different philosophies.
Design & Build Quality
Pick up the Razor C35 and the first thing you notice is the steel. It has that slightly old-school, overbuilt feel - the frame feels dense and rigid, with very little flex when you rock it side to side. The big front wheel gives it a "mini penny-farthing" vibe, but in person it looks more purposeful than gimmicky. Cabling is reasonably tidy, though a few exposed runs near the stem remind you this is more practical than premium.
The KuKirin S1 Max goes the opposite direction: aluminium frame, lighter, leaner, more "foldable furniture" than "urban tank". The folding joints and levers are clearly designed for speed - fold, run for the train, unfold, go. There is a bit more play in the system; fresh out of the box it's fine, but you can feel that if anything is going to loosen up after a few months of cobblestones, it's the stem clamp, not the deck.
In terms of visual design, the C35 is honest and a bit industrial - it won't turn heads, but it also won't look ridiculous outside an office. The S1 Max wears the budget-sport look: matte black, a few bright highlights, and those honeycomb tyres giving away its low-maintenance intentions. Neither feels genuinely premium, but the Razor feels more solid in the hand, where the KuKirin feels more optimised for the warehouse scale.
Ride Comfort & Handling
This is where the two scooters feel like they're from different planets.
The Razor C35's giant front pneumatic tyre does most of the comfort heavy lifting. Roll into a patchwork of cracked asphalt, tram tracks and uneven slabs and the front end just calms everything down. That tyre soaks up sharp edges you'd usually brace for. The rear is smaller, still air-filled, so you do feel hits in your heels, but front-wheel composure makes the whole scooter feel more relaxed and predictable. It tracks straight, doesn't twitch, and generally encourages you to look up and enjoy the ride rather than laser-scan every centimetre of tarmac.
The KuKirin S1 Max, by contrast, announces every imperfection. Solid honeycomb tyres plus basic suspension is always a compromise. On smooth bike lanes, it's fine - firm but acceptable, with the suspension taking the sting off minor cracks and joints. Once you enter "European old town" territory - cobbles, patched repairs, root-lifted slabs - the vibrations start working their way into your knees and wrists. After a few kilometres of that, you will find yourself searching for the smoothest possible line, or just slowing down because your spine insists.
Handling also shows the design differences. The C35's big front wheel and longish deck make it stable and forgiving. Sudden steering inputs feel damped; it doesn't want to dart left and right, which is fantastic for newer riders and anyone who's had a scary moment on tiny-wheeled rentals. The S1 Max is more nimble but also more nervous. At its top allowed speed it feels light on its feet - good for weaving around pedestrians, less good when a pothole appears out of nowhere and those little wheels react like they've hit a brick.
Performance
On paper, both scooters use a similar-rated rear hub motor and live in the same modest-commuter class. On the road, the character of that power is different.
The Razor C35 pulls away in a very measured way. Kick to start, thumb the throttle, and it builds speed smoothly rather than snapping forward. For new riders or anyone sharing crowded bike lanes, that calm response is reassuring. Once up to its maximum sport-mode pace, it feels composed, particularly thanks to that front wheel - you never get the sense it's out-running its own chassis.
Hill performance is exactly what you'd expect from a single modest motor: gentle slopes, bridges and ramps are fine; sustained or steep climbs quickly expose the limits. With an average-weight rider you can trundle up most urban gradients, but forget about bombing up steep hills at full speed - the motor settles into a determined plod, and you'll occasionally be tempted to add a few human kicks.
The KuKirin S1 Max actually feels a touch more eager off the line, especially in its higher ride modes. It spins up briskly to its capped top speed, and on flat ground it feels snappy enough for city use. The throttle mapping is still quite civilised - no nasty jerks - but the lighter chassis amplifies any acceleration and braking inputs. On small rises it holds speed reasonably well, but once you venture onto proper hills, it behaves just like the Razor: gradual slowing, then "OK, help me out here" vibes if you're near the max load.
Neither scooter is going to rearrange your face with acceleration or storm up alpine climbs. They're built for predictable, safe commuting pace, with enough torque to deal with everyday city terrain, not stunt riding.
Battery & Range
This is where the KuKirin S1 Max starts waving its spec sheet around.
The Razor C35's battery is on the small side for an adult commuter. In careful eco riding with a light rider, you can flirt with the claimed range, but in the real world - mixed speeds, a few hills, normal rider weight - you're realistically looking at a daily loop in the high teens of kilometres before you start watching the bars more than the scenery. For short commutes it's fine; for longer city sprawl or detour-heavy days, you'll want a workplace charging spot.
The S1 Max counterpunches with a considerably beefier pack. In everyday use it comfortably stretches beyond the C35, and you feel that difference. A there-and-back commute of around ten kilometres each way is no drama, even if you ride in the fastest mode and don't baby the throttle. There's headroom for extra errands without the silent anxiety of "do I have enough to get home?" that smaller batteries can induce.
Charging times are similar - think overnight or full workday rather than long-lunch top-up. Neither offers anything resembling fast charging, but given the battery sizes and prices, that's par for the course.
Portability & Practicality
Both scooters land in the "portable enough, but you'll feel it" zone, though they annoy you in slightly different ways.
The Razor C35 is a touch lighter on the scale, but the big front wheel and non-folding handlebars mean that once folded, it's more of an awkward bundle than a neat package. Carrying it up a couple of flights is doable; doing that daily to a top-floor flat is an unspoken gym membership. On trains and in tight hallways, the fixed bar width is what you fight with more than the mass.
The KuKirin S1 Max folds into a much more commuter-friendly shape. The stem clamps down to the rear, the whole package becomes shorter and less intrusive, and it's just that bit easier to swing into a car boot, park in a shared office corner or stash in a corridor without collecting enemies. The weight is slightly higher, but the balance when carried and the cleaner folded form make it feel more portable in real life.
In day-to-day practicality, the tyres tell different stories. The Razor's pneumatic set-up means you get puncture risk along with comfort; if you're unlucky with glass or debris, you'll eventually enjoy the charming experience of changing scooter inner tubes. The S1 Max's honeycomb tyres eliminate that particular joy entirely - you just ride, forget about pressures, and your main "maintenance" is occasionally tightening bolts and charging the battery. If your tolerance for unexpected problems is low, that's a big point in KuKirin's favour.
Safety
Safety is more than just brakes and lights, but let's start there.
Both scooters use a combination of electronic braking and a rear fender stomp. The Razor C35's setup feels slightly more confidence-inspiring largely because of the chassis and wheel configuration. When you really lean on the brakes, the big front tyre and long wheelbase help keep things composed. You do have to commit to that rear fender for maximum stopping power, which feels a bit retro for an "adult" scooter, but the redundancy is comforting - if the electronics throw a wobbly, physics still works.
The KuKirin S1 Max uses a similar philosophy: front electronic brake for everyday slowing, rear fender for real emergency stops. On its small solid tyres, grabbing full braking feels a bit more dramatic; there's less mechanical grip available and more chance of a small skid if you ham-foot it. You quickly learn to plan your stops a touch earlier and use the regen brake proactively rather than reactively.
Lighting on both is adequate for being seen and doing low-to-moderate-speed night runs in lit areas. The Razor's brake-activated rear light is welcome - it communicates intent clearly to following traffic. The KuKirin's lights are similarly visible, but neither is what I'd call "country-lane at midnight" bright; think of them as city-commute capable, not searchlights.
Where the Razor C35 quietly scores is passive safety: that huge front wheel simply copes better with surprise potholes and curb drops. If you ride in a city where road maintenance is a theory rather than a practice, that's not a small detail. The S1 Max demands more vigilance from the rider - it can do the job, but you really need to keep your eyes open and your line clean.

Price & Value
On sticker price alone, the KuKirin S1 Max comes in cheaper and still manages to deliver a larger battery, suspension and similar motor output. If you judge scooters as "how much mobility do I get for this much cash?", the S1 Max looks like the smarter buy. It gives you more daily range and features for less money - hard to argue with.
The Razor C35 counters with non-glamorous value: frame durability, UL-rated electrics, and a design that feels like it's built to survive actual commuting abuse. If you spread the cost over a few years of short trips, it still makes sense, but it never feels like a screaming bargain - more like a sensible, conservative purchase.
If budget is tight and numbers matter most, the KuKirin is the obvious pick. If you're willing to pay a bit more for a known brand and a more confidence-inspiring ride, the Razor can still justify its price - just don't expect miracles from that tiny battery.
Service & Parts Availability
Razor's advantage is simple: they've been around forever, and they have an established distribution and support network. Getting basic parts - tyres, tubes, brake bits - is usually straightforward, and you're more likely to find authorised service partners, especially in bigger markets. Documentation tends to be clear, and you're not left combing obscure forums in three languages just to find a replacement latch.
KuKirin (Kugoo) has improved noticeably in Europe, with regional warehouses and better logistics than many nameless rebrands. However, support can still be a bit of a lottery. There are parts around, and the large community helps with guides and hacks, but you're often dealing with third-party sellers or generic spares. If you're reasonably handy with tools and comfortable with DIY, that's fine; if you want "drop it at a shop and forget about it" service, Razor is usually the more reassuring badge.

Final Verdict - Which Should You Choose?
If you strip away the marketing and live with these scooters like I did, you end up with a fairly clear personality split.
The KuKirin S1 Max is the spreadsheet winner: more range, suspension, solid tyres, lower price. For flat cities with decent bike infrastructure, and especially for riders relying on trains and lifts, it makes a lot of practical sense. You get solid everyday capability without spending big, as long as you accept that the ride will get quite "chattery" when the tarmac runs out and that the overall feel is firmly budget-class.
The Razor C35 is the calmer, more confidence-inspiring ride. Its big front wheel and stout frame give it a composure the S1 Max simply can't match on rough or unpredictable surfaces. It feels like a simpler, more honest machine - no app nonsense, fewer gimmicks - just a scooter that gets on with the job. The trade-off is clear: comparatively short legs and some dated touches in the braking and ergonomics.
My take: if you're chasing maximum kilometres per charge and want the cheapest reasonable way to stop buying bus tickets, the KuKirin S1 Max is your tool. If you're new to scooters, value stability over stats, and your daily loop is on the shorter side but across mixed or shabby surfaces, the Razor C35 is the one that will have you feeling more relaxed - and less surprised - on every ride.
