Fast Answer for Busy Riders ⚡ (TL;DR)
The GOTRAX GMAX Ultra is the stronger overall commuter: it goes noticeably farther on a charge, feels calmer at speed, and delivers a more complete daily-vehicle experience, especially if your rides are more about distance than drama. The Razor C45 counters with a slightly punchier motor, a big confidence-inspiring front wheel, app tweaks, and a lower price - but its range, rear-end comfort, and braking leave it feeling more like an upgraded toy than a true long-haul workhorse.
Choose the GMAX Ultra if you want to forget about daily charging and treat your scooter as a primary mode of transport. Choose the C45 if your rides are short, your roads are smooth, and you value brand familiarity and that chunky front wheel more than long-range stamina.
If you want to know which one will actually keep you happy after a few hundred kilometres of real commuting, keep reading - the devil is very much in the details.
Electric scooters have grown up fast, and both the GOTRAX GMAX Ultra and Razor C45 are pitched as proof that "the kids' brands" can build adult-grade commuters. I've put real kilometres into both: city centre bike lanes, suburban paths, broken tram tracks, and the occasional "this definitely isn't a road" shortcut.
On paper, they sit in the same neighbourhood: single-motor commuters, similar top speeds, similar weights, aimed at adults who want to get to work without smelling like a gym. In practice, they take very different approaches - one quietly tries to be your everyday transport, the other still carries a little bit of the toy-aisle DNA in its bones.
If you've narrowed your list to these two, you're already thinking like a practical rider. Now let's figure out which one suits the way you actually live, not just what looks good on a spec sheet.
Who Are These For, and Why Compare Them?
These two live in that mid-priced, "semi-serious" commuter class. You're paying more than for a flimsy supermarket scooter, but you're not yet in the land of dual motors, hydraulic brakes, and weekend track-day heroes.
The GMAX Ultra is aimed squarely at the urban adult who wants to replace a fair chunk of their public transport or car use. Think longer commutes, errands after work, and the occasional detour just because the weather is good. It's the kind of scooter you buy when you're tired of range anxiety and rental apps.
The Razor C45, despite its grown-up paint job and big front wheel, still feels tuned for the shorter-haul rider: last-mile from park-and-ride, campus commuting, relatively flat city hops. It's for someone who wants something sturdier than a kids' Razor, but doesn't necessarily need a "bring me home from anywhere" battery.
They're natural competitors because they share similar speeds, roughly similar heft, and comparable price brackets - but they trade very differently between range, comfort, and long-term practicality.
Design & Build Quality
Park them side by side and the differences are instant. The GMAX Ultra looks like a modern commuter scooter: mostly internal cabling, clean stem, integrated display, muted colours. It doesn't shout for attention and wouldn't look out of place next to office bikes in a corporate lobby. The frame feels reassuringly dense - not exotic, but solid in a "this will survive winter" way.
The Razor C45 has more of a "grown-up toy" vibe. Steel frame, visible welds, and that oversized front wheel give it a slightly industrial, almost prototype look. Up close, some details feel a bit more old-school: more exposed hardware, a slightly busier cockpit, and a deck that looks functional rather than refined.
In the hands, the GMAX's aluminium frame and integrated bits feel more contemporary. The flush-mounted display, internal routing, and built-in lock suggest someone thought about the daily life of a commuter, not just the showroom photos. There's still the odd cost-cutting detail - the rear hook and fender don't quite match the rest of the scooter's solidity - but it's largely cohesive.
On the C45, the steel construction does give it a robustness you can literally feel. It's the sort of scooter you'd happily lend to a friend who treats hardware like gym equipment. But the mismatch between that big, plush-looking front tyre and the hard rear arrangement hints at a design built more around stand-out features than around a balanced, premium feel.
If we're talking pure perceived quality in day-to-day use, the GMAX Ultra edges ahead with its more modern, better integrated design, even if neither machine is exactly a work of art.
Ride Comfort & Handling
Here's where their personalities really separate.
The GMAX Ultra rides like a classic, no-suspension long-range scooter: big air-filled tyres, long-ish wheelbase, and a low centre of gravity thanks to that hefty battery in the deck. On decent tarmac and normal bike-path imperfections, it's pleasantly composed - more "electric bicycle-ish" than "toy scooter on caffeine". After several kilometres, your knees and wrists are still on speaking terms.
The catch is that when the surface turns properly bad - old cobbles, patched concrete, tram track crossings - you're reminded quickly that there are no springs anywhere. The 10-inch tyres do a lot of work, but they can't perform miracles. You end up riding with active knees and picking lines carefully, especially at speed.
The Razor C45 is a split personality. The front end, with its big air-filled wheel, is genuinely good. It rolls over cracks and small potholes with a confidence you don't get from typical entry-level scooters. The steering feels stable rather than twitchy, and that extra diameter helps a lot when you inevitably hit something you didn't see.
Then the rear end arrives, and the romance ends. The solid tyre on a rigid steel tail transmits every imperfection straight into your legs and spine. On smooth surfaces, it's fine - almost pleasant. On broken city streets, the back of the scooter chatters and thumps in a way that gets old fast. After a few kilometres of rough pavement, you're constantly shifting weight forward, bending your knees, and silently apologising to your joints.
Handling-wise, both are stable enough at their top speeds, but the GMAX Ultra feels more balanced front-to-back, whereas the C45 is "front good, rear grumpy". If your city has half-decent surfaces, either is manageable. On typical European "we'll fix that road next year" tarmac, the GMAX is the one that treats your body more kindly overall.
Performance
In everyday acceleration, the Razor C45 does feel a bit more eager. Its motor has a touch more punch off the line and in the mid range, and in Sport mode it pulls you up to its top speed with a sense of "let's get this done" rather than "we'll get there eventually". It's not a beast, but it's certainly not lethargic.
The GMAX Ultra, with its slightly milder motor, takes a more measured approach. It gets up to its cruise speed at a sensible pace - quick enough for traffic, slow enough not to scare a first-time rider. Rear-wheel drive on both scooters helps traction, so neither is especially skittish under throttle, even in the wet, as long as you behave.
Top-speed feeling is similar: once you're up there, both scooters are in that "fast enough to feel efficient, slow enough to still feel in control" zone. The GMAX's longer wheelbase and even tyre setup make it feel a bit more planted; the C45 is stable thanks to the front wheel but made slightly nervous by bumps hitting that solid rear at speed.
On hills, neither scooter is going to impress riders coming from dual-motor monsters. The C45's extra motor power gives it a small edge on short, moderate inclines - it hangs onto speed a bit better as long as the slopes aren't ridiculous and the rider isn't at the weight limit. The GMAX Ultra will grind up typical city bridges and gentle hills, but on steeper stuff you can feel the motor working and speeds drop to "patient commuter" levels.
Braking is another story. Both have rear disc setups with electronic assistance, but the C45's stopping performance at full tilt does not inspire the level of confidence I'd like for a steel-framed scooter going that fast. You learn quickly to look far ahead and brake early. The GMAX Ultra isn't a benchmark either, but its braking feels a bit more predictable and progressive - the scooter feels less eager to push you on when you really need it to sit down and behave.
In short: Razor wins by a nose on punch and hill grunt, but GOTRAX feels more composed and confidence-inspiring when you're actually living with the thing.
Battery & Range
This is where the GMAX Ultra stops playing nicely and simply walks away from the C45.
The GMAX packs a noticeably larger energy store built from branded cells, and you feel it on every ride. Real-world mixed riding - not babying it, but not flat-out all the time - comfortably gets you well beyond what most commuters need in a day. Many owners report charging every few days, not every night. That changes how you think about the scooter: it stops being a gadget you constantly manage and starts feeling like an actual vehicle.
The C45, by contrast, feels much more like the classic "mid-range toy" in this area. On paper the claimed distance sounds respectable; in reality, ridden at normal city speeds with some hills and a normal adult on board, you're looking at a commute-friendly but unremarkable range. Enough for shorter daily trips, yes; enough to forget about the battery for days at a time, no.
Both take around a working day or overnight to charge from empty, but because the GMAX's battery is larger, its average charging speed is actually a bit higher in practice. More importantly, that big pack with quality cells holds voltage more consistently: the GMAX keeps its performance more stable deeper into the battery, while the C45 feels more "tired" once you're into the lower bars.
If you hate range anxiety or routinely chain trips together - office, gym, friends, home - the GMAX Ultra is in a different league. The C45 is fine for people with short, predictable routes, but it doesn't offer the same "I'll just keep going" confidence.
Portability & Practicality
Both scooters live in the "doable but not fun" weight class. You can carry them up a flight of stairs, but you wouldn't volunteer to do stair repeats with either. The Razor C45 is a bit lighter, and you do feel that when you're hoisting it into a car boot or onto a train, but once you're past about 15 kg, differences are more "slightly less annoying" than "transformational".
The GMAX Ultra folds with a reassuring, almost overbuilt clamp; when locked, the stem feels solid with minimal play, which you appreciate at speed. Folded, it's bulky more because of width and big tyres than length. Fine for a car or under a desk, but awkward in very tight spaces or packed public transport.
The C45's folding system is straightforward and secure enough, but the oversized front wheel means the folded package is taller and slightly more awkward to manoeuvre through doorways or down train aisles. It does, however, feel a bit less of a brick in your hands due to the lower weight, and the steel frame gives confidence when you inevitably bonk it into something.
On everyday practicality, the GMAX Ultra scores useful real-world wins: the integrated cable lock in the stem is genuinely handy for quick stops, so you're not constantly fumbling with a separate lock for a two-minute bakery run. Its deck is also more generous, which matters more than most people think on day fifteen of your commute.
The C45 answers with Bluetooth app customisation. Being able to tweak kick-to-start and cruise control from your phone is nice, though not life-changing. It turns the scooter into more of a connected gadget, which some riders will love and others will ignore after the first week.
If your life involves frequent carrying and multi-modal hops, the C45 gets a small nod. If it's mostly door-to-door scooting with the occasional shop stop, the GMAX Ultra is the more convenient long-term partner.
Safety
Safety is where their design philosophies collide head-on.
The Razor C45 leans hard on that large pneumatic front wheel and UL-certified electrical system. And there's no question: that front tyre makes a big difference in not crashing into every imperfection you meet. Straight-line stability at higher speeds is excellent, and you're less likely to be surprised by a cracked paving stone. Battery and electronics certification is a plus in an era where cheap packs occasionally make the news for the wrong reasons.
However, braking performance on the C45 is a weak link. The combination of its weight, steel frame momentum and average disc tuning means that from top speed, you need to think a bit further ahead than you'd like. You get used to it, but you never quite love it.
The GMAX Ultra doesn't have the fancy certification badge, but it does most of the basics well. Dual braking (mechanical plus electronic), predictable deceleration, and a very stable chassis at commuting speeds. Its lighting is perfectly serviceable for urban riding, and the brake-activated rear light and reflectors make you reasonably visible in traffic. It's not night-riding nirvana, but you're not invisible either.
Tyre-wise, the GMAX's matching pneumatic tyres front and rear give a more consistent grip and behaviour when cornering and braking, especially on wet surfaces. The C45's solid rear tyre will never puncture, which is great, but it also offers less feedback and grip on marginal surfaces, particularly under braking or over painted lines in the rain.
Both scooters are "safe enough if ridden sensibly", but if I had to loan one to a less experienced rider for mixed city use, I'd rather they had the GMAX Ultra beneath them.

Price & Value
Price-wise, these two are in the same ballpark, with the Razor C45 clearly positioned as the cheaper option and the GMAX Ultra asking for a bit more upfront.
The question is what you get for that extra cash. With the GMAX Ultra, most of your money goes into the battery and a more complete commuter package: branded cells, significantly longer practical range, better deck, integrated lock, and a design that feels closer to a Ninebot-style "serious commuter" than a beefed-up toy. If you actually use your scooter a lot, the cost per kilometre tends to come out very favourable.
The Razor C45, at its full list price, is... acceptable value. You're paying for the name, the big front wheel, and the safety certification as much as for actual performance. When it's discounted, the proposition improves dramatically; at a good sale price, it becomes a perfectly defensible choice for short, flat commutes where range isn't critical and you just want something sturdier than the ultra-budget stuff.
For a daily rider who will clock serious distance over the years, the GMAX Ultra feels like the more sensible investment. For an occasional rider or shorter-hop commuter watching the budget, the C45 can make sense - especially if you catch it at the right price.
Service & Parts Availability
Both brands are established, which already puts them ahead of many anonymous Amazon specials.
GOTRAX has been steadily improving its support game. Parts for the GMAX series are reasonably obtainable, and there is a decent ecosystem of DIY guides and community experience around repairs. Response times from support can still be hit or miss depending on where you live, but you're not dealing with a ghost company.
Razor, as the old kick-scooter giant, has a long history of parts availability and documentation. That heritage counts: if you break a lever or need a new tyre, you're unlikely to be hunting obscure forums. For basic wear components, the support experience is usually straightforward. Where things become more mixed is with batteries and electronics - some riders report smooth warranty service, others less so, but that is sadly typical across the whole industry.
In Europe, neither brand is at the level of the absolute top commuter names in terms of dealer networks, but both are serviceable choices. Razor probably wins on sheer legacy and parts familiarity; GOTRAX wins on having a more modern commuter-focused product line.

Final Verdict - Which Should You Choose?
If you strip away the brand nostalgia and look purely at how these scooters behave under real commuters, the GOTRAX GMAX Ultra feels more like a genuine transport tool. Its big battery, calmer chassis, and more mature design make it better suited to people who will actually rely on it - not just for a summer fling, but for day-in, day-out commuting.
The Razor C45, while likeable in some ways, sits awkwardly between worlds. The big front wheel and punchy motor are welcome, and the price can be tempting, but the combination of modest real-world range, harsh rear ride, and only-average braking means it makes more sense as a short-hop, mostly-smooth-surface solution - a beefy campus scooter, a park-and-ride connector - rather than as a true car replacement.
If your priority is range, fewer charges, and a scooter that feels closer to "serious vehicle" than "grown-up toy", the GMAX Ultra is the clear pick. If your rides are short, flat, your roads are kind, and your wallet is not, the C45 can still earn its place - just go in with your eyes open about its limitations.

These metrics show, in cold maths, where each scooter shines. The GMAX Ultra dominates anything range- and efficiency-related: you get more distance per euro, per kilo, and per watt-hour. The C45 does better on power-related ratios and value per unit of top speed: more motor per kilo and per euro, which matches the slightly punchier feel on the road. Charging speed and pure cost-per-kilometre, however, clearly favour the GMAX Ultra.

Totals: GOTRAX GMAX Ultra scores 37, RAZOR C45 scores 18.
Based on the scoring, the GOTRAX GMAX Ultra is our overall winner. As a daily rider, the GOTRAX GMAX Ultra simply feels like the more complete companion: it goes further, rides calmer, and asks fewer favours from you in planning, charging, and route selection. It's not exciting in a headline-grabbing way, but it quietly gets almost everything important right. The Razor C45 brings some charm - that big front wheel, the punchy motor, the familiar name - but once the novelty fades, its shorter legs and harsher manners hold it back. If you want a scooter to become part of your life rather than just your weekend, the GMAX Ultra is the one that's far more likely to keep you genuinely happy over the long haul.
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.
