Fast Answer for Busy Riders ⚡ (TL;DR)
The GYROOR H40 is the clear overall winner here: it rides well enough, keeps kids happy with a proper light show, and does it all for a price that actually makes sense for a children's toy-turned-vehicle. The SIMATE S5 feels nicely designed and impressively light, but its tiny battery and modest performance are hard to swallow at a cost that belongs in the adult high-performance segment, not the kids' park circuit.
Choose the SIMATE S5 only if ultra-low weight, dual suspension and a very carefully safety-focused package matter more to you than value, and you're consciously overpaying for a "premium kids' gadget." Everyone else - especially parents who like their wallets - will be far happier with the GYROOR H40 as a fun, capable and far more rational choice.
If you want to understand where each scooter shines (and where the marketing gloss wears off quickly), read on - this comparison will save you both money and arguments with your child later.
Electric scooters for kids used to be rattly toys that squeaked their way through half a summer before dying behind the garden shed. Those days are largely gone: today's junior scooters borrow a lot from the adult segment - aluminium frames, brushless motors, lithium batteries, even half-decent lighting.
The SIMATE S5 and the GYROOR H40 both sit in this new "mini real scooter" category. On paper, they promise similar things: a first e-scooter experience for kids, simple controls, bright lights, and enough speed to feel exciting without turning family outings into ER visits. In reality, they take wildly different approaches, especially when it comes to how much they expect you to pay for those smiles.
Think of the SIMATE S5 as the ultra-light, feature-rich but seriously overpriced kids' option, and the GYROOR H40 as the "does 90 % of the job for a fraction of the money" scooter. Which one you should choose depends on your budget, your terrain - and how much you're willing to pay for marginal gains. Let's dig in.
Who Are These For, and Why Compare Them?
Both scooters are clearly aimed at children and younger teens, not adults playing "just one try" in the driveway. The SIMATE S5 is pitched for kids from around primary school to early teens, with a strong emphasis on being featherweight and easy to handle. The GYROOR H40 targets roughly the same age bracket, skewing slightly older and heavier, with a bit more poke in the motor and a longer claimed riding time.
They are natural competitors because they promise the same thing to parents: "Buy this instead of another console, your child will go outside, and you won't constantly worry they'll break their neck." Where they diverge is how they split the budget between hardware, comfort and safety - and more importantly, how much of your budget they feel entitled to.
Design & Build Quality
Pick up the SIMATE S5 and the first impression is: "Is that it?" The weight is almost comically low. The mixed metal-plastic chassis feels reasonably tight, the deck is decently reinforced, and the whole thing looks more like a shrunken 'real' scooter than a toy-shop special. The LED display on the bar is a nice touch, giving little riders that cockpit feel. However, plasticky detailing in some areas and the sense that every gram has been shaved off do remind you this isn't built like a tank. It's more of a carefully dieted commuter for small humans.
The GYROOR H40, by contrast, feels more substantial in the hand - still light enough, but with a more reassuring aluminium chassis and fewer parts that scream "if you sit on this wrong, it'll crack." The finish is closer to budget adult scooters than toy hardware: metallic paints, simple but solid folding latch, and a deck that doesn't flex nervously when you lean into it. The integrated lighting strips along the deck edges make it look like a rolling gaming rig, which, let's be honest, is exactly what many kids want.
In terms of pure build impression, the H40 feels less fragile and closer to proper vehicle territory. The S5 looks smart and well thought out, but the price-tag suggests ultra-premium, while some components still feel firmly mid-range.
Ride Comfort & Handling
On comfort, the SIMATE S5 pulls a clever card: dual springs on a kids' scooter. With small solid tyres, that's not just a gimmick - it genuinely matters. On smooth paths, the S5 glides nicely and shrugs off the usual cracks and expansion joints that would normally have small riders chattering their teeth. Take it across a few hundred metres of rougher sidewalk and, while you still feel the surface, your knees don't file a complaint five minutes in. The short wheelbase and light weight make it flickable - almost too flickable for taller kids, who will notice it feeling a bit skittish at higher speeds or on uneven ground.
The GYROOR H40 goes the simpler route: no suspension, slightly larger solid tyres, and trust in rubber compound. On good tarmac or park paths, it's pleasantly smooth and quiet. Start hitting older paving stones or lumpy sidewalks and you feel exactly what you see - every ridge and crack. It never gets brutal, but you are reminded this is a rigid scooter; long rides on broken surfaces will have smaller riders shifting their stance to get more comfortable. Handling-wise, though, it's stable and predictable, with a bit more planted feel than the S5 when you start leaning through faster turns.
So: SIMATE wins on pure bump absorption thanks to those springs, but the H40 counterpunches with a calmer, more confidence-inspiring stance. For bigger kids or longer rides, that stability matters at least as much as filtering out micro-vibrations.
Performance
Performance in this class isn't about top-speed heroics; it's about "does it feel exciting without becoming a physics lesson in momentum and regret." The SIMATE S5's motor sits firmly in the "gentle encouragement" category. For lighter kids, it pulls well enough on the flat - more exciting than kicking, less exciting than a cheap e-scooter on YouTube. Acceleration is nicely progressive, which is exactly what you want when a seven-year-old experiments with full thumb throttle for the first time. But once you hit even mild inclines, the limits show quickly. The scooter keeps going, but hills become more "patient buzzing uphill" than "let's conquer that slope."
The GYROOR H40 has noticeably more shove. Off the line, smaller riders get a pleasing nudge that actually feels like an upgrade from a kick scooter, not just a powered assist. On flat ground, it happily cruises at a pace that will make a nine-year-old feel like a superhero and parents brisk-walk to keep up. The speed modes are genuinely useful: start in the gentle setting for nervous beginners, then unlock the higher mode once they've proven they can steer without heading straight for the nearest parked car. On mild hills the H40 holds its pace more convincingly than the S5; on steeper ones you'll still end up with kick-assist, but it doesn't die the moment the gradient starts.
Braking on both is dual: electronic and rear fender. The S5's electronic brake feels more like a soft drag, handy for trimming speed but not something you'd rely on for panic stops. The foot brake is the real worker here, and kids used to kick scooters will adapt instantly. The H40's electronic brake is better tuned - you can noticeably scrub speed with your thumb, then stomp the fender if you've misjudged that driveway. Confidence-wise, the H40 feels like it has more in reserve when you need to bring things under control in a hurry.
Battery & Range
This is where the spec sheet stops whispering and starts shouting. The SIMATE S5 carries a very small battery. In practice, you're looking at short neighbourhood adventures: loops around the park, a ride to a friend's house a few streets away, or half an afternoon of on/off use. Ride continuously at its top pace, especially with an older or heavier kid, and you'll be back on the charger surprisingly soon. The upside is that the battery refills quickly - a couple of hours and you're good again - but you will notice just how often you're plugging it in if your child really falls in love with riding.
The GYROOR H40, while hardly a long-distance tourer, offers a noticeably longer leash. Under a light-to-average kid, you can get a solid hour or so of real-world play before the performance drops off. Older or heavier riders, or constant full-throttle antics, cut that down, but you still get more practical ride time than on the S5. Charging is similarly quick, which is a big win in the "Saturday morning: flat battery, impatient child" scenario.
Range anxiety on the S5 is very real on days when the scooter is the main event; on the H40, it's more of a "we should probably top it up before this afternoon as well" sort of thought.
Portability & Practicality
Portability is where the SIMATE S5 genuinely shines. It is properly light - the kind of light where a primary school kid can pick it up and carry it up a flight of stairs without turning it into a dramatic performance. The folding process is basic but effective: loosen, fold, hook. Once folded it's tiny; it disappears into car boots, under beds, next to shoe racks. If you live up several storeys without a lift, this matters a lot.
The GYROOR H40 is still in the "easy to live with" category, just not in the same bantamweight league. Most parents will carry it one-handed without grumbling, but younger kids will grumble, especially over longer distances. The folding latch is more modern and quick to operate, and once folded it's short and tidy enough to fit in most city-car boots with room to spare. For school runs, trips to the park and holiday packing, it's absolutely fine - just not as effortlessly tossable as the S5.
On pure practicality, the S5 wins for families with stairs, limited storage, or kids who genuinely need to lift and move their scooter often. Everyone else will find the H40 perfectly manageable and less compromised elsewhere.
Safety
Both scooters take safety much more seriously than the old "stick a motor on a toy and hope" era. The SIMATE S5 has a very sensible kick-to-start system, which prevents accidental rocket launches while a child is just standing on the deck fiddling with the throttle. Combined with its modest speed and very gentle power delivery, it's an inherently forgiving package. Dual braking, non-slip deck, and bright lights along the deck and up front all add layers of passive safety. The overall feeling is "wrapped in cotton wool, but in a good way."
The GYROOR H40 answers with certification and visibility. That UL battery certification isn't glamourous, but it's exactly the sort of thing you want quietly on your side when it's charging in a bedroom overnight. The dual braking system is well tuned for actual stopping power, and the motion-triggered deck lighting turns the whole scooter into a rolling beacon at dusk. The H40 does carry a bit more speed and mass, so falls can be slightly more dramatic, but the extra control from its brakes and stable chassis goes some way to balance that.
If your absolute top priority is "as safe as possible, even at the cost of fun and money," the SIMATE plays that role well. If you want a more balanced mix of safety, capability and price sanity, the H40 looks the more convincing package.

Price & Value
This is the section where the SIMATE S5 starts sweating. Its asking price catapults it into a league normally occupied by serious adult commuters or powerful hobby machines. For a kids' scooter with a very small battery and modest motor, that's a hard pill to swallow, no matter how carefully you wrap it in safety features and suspension springs. You are paying a luxury premium for a product that, in real use, behaves like a very pleasant but still fairly basic children's scooter.
The GYROOR H40, by contrast, sits in the "impulse big gift" bracket. It costs less than many smartphones and considerably less than a half-decent mountain bike, yet brings solid hardware, lights, safety certification and perfectly adequate performance. Is it flawless? No. But when you stack the fun-per-euro equation, the H40 looks like a rational purchase. The SIMATE S5 feels more like an emotional one, and an expensive emotion at that.
Service & Parts Availability
SIMATE positions itself as a micro-mobility brand with decent documentation and typical one-year coverage on main components. That's fine on paper, but outside dedicated online retailers and their own channels, you don't see S5 parts flooding the aftermarket. For typical wear items (tyres, grips, basic hardware), you'll manage; for more specific components, you may quickly be in "contact seller and hope" territory.
GYROOR, thanks to its hoverboard history, has a broader base of users and parts floating around online. Chargers, decks, fenders and other bits appear more frequently through third-party sellers. Their reputation for actually answering emails and sending out replacements isn't legendary, but it's more positive than many similarly priced brands. For parents, that means a broken fender or dodgy charger is more likely to be a temporary setback than a scooter death sentence.

Final Verdict - Which Should You Choose?
Seen purely as scooters, the SIMATE S5 and GYROOR H40 aren't worlds apart: both give kids a safe, fun taste of electric mobility, both roll on solid tyres, both are light, both have dual brakes and flashy lights. The difference is in how honestly they're priced against what they actually deliver.
The SIMATE S5 is a likeable machine trapped inside an outrageous price. The dual suspension and ultra-low weight are genuinely nice, and for smaller, nervous kids its gentle character and kick-to-start safety make it a stress-free first step into e-scooters. If money is no object and you value that soft, cushioned feel above everything, you could justify it - just go in knowing you're paying adult high-performance money for very modest specs.
The GYROOR H40, meanwhile, feels far more in tune with reality. It's not perfect - the rigid chassis can be jiggly on bad pavements, and heavier kids will outgrow its power - but it offers a solid frame, more punch, more usable range and better value by a staggering margin. For most families, it's simply the smarter choice: you get a capable, exciting scooter that won't make you wince every time it tips over or scrapes a curb.
If I had to put my own money down for a typical kid in a typical suburb, I'd pick the GYROOR H40 every time, and spend the saved cash on a good helmet, some pads - and maybe a celebratory ice cream on the way back from the first ride.
