LAMAX eFlash SC20 vs Jetson Relay - Which Kid's E-Scooter Actually Deserves Your Money?

Fast Answer for Busy Riders ⚡ (TL;DR)

The LAMAX eFlash SC20 is the more rounded, confidence-inspiring kids' e-scooter and the one I'd recommend to most parents: better safety execution, sturdier feel, longer real-world range, and a build that seems made to survive siblings, not just one season.

The Jetson Relay counters with slightly lower weight, adjustable handlebars and a friendlier sticker price, but its tiny battery, weak hill performance and spotty reliability make it feel more like a short-lived electric toy than a junior vehicle.

Choose the Relay only if your child rides on flat suburban pavements, doesn't need long sessions, and you're very price-sensitive; everyone else will get more peace of mind and more usable fun from the LAMAX.

Now let's dig into how they really compare when you live with them, not just glance at the box.

Children's e-scooters are a strange niche. Parents want "safe and sensible"; kids want "fast and cool"; manufacturers try to somehow please both without ending up in the emergency room or the bargain bin. The LAMAX eFlash SC20 and Jetson Relay sit right in this crossfire, promising to be the perfect first electric ride.

I've spent time riding both (yes, adult on kids' scooters - neighbours stare, you get used to it) and, more importantly, watching actual kids abuse them the way only kids can: kerb drops, gravel shortcuts, full-throttle into every tiny incline on the street. On paper they live in the same world: lightweight, entry-level, speed-limited, with solid tyres and basic braking.

In practice, though, one of them behaves like a small but serious scooter shrunk for kids, and the other like a clever big-box toy with a motor. Let's unpack that.

Who Are These For, and Why Compare Them?

Both scooters target roughly the same life stage: the post-Razor, pre-teen years when kids are bored of kicking but not ready for full-fat commuter power. The Relay leans slightly older on paper, but in reality we're talking primary school riders in both cases.

The LAMAX eFlash SC20 is designed for younger riders in that spectrum - think early school age to around ten - with a weight limit that comfortably covers most kids in that range and a riding position clearly optimised for smaller bodies. It's built more like a "mini vehicle": steel frame, no-nonsense layout, speed capped at a level that still feels exciting, but never terrifying.

The Jetson Relay pushes itself as the "first real e-scooter" for eight-plus kids, particularly in flat North-American suburbia. Adjustable bars and that familiar Thumb-throttle-plus-foot-brake combo scream "starter scooter". It's meant to be something a grandparent can pick up at a warehouse store and feel like an absolute legend on Christmas morning.

They compete because parents will often cross-shop them as roughly similar priced, lightweight, kids' e-scooters that don't need a PhD in electronics to operate. One is clearly more long-term and robust; the other, more impulse-buy friendly. Which matters more to you is the whole game.

Design & Build Quality

Pick up the LAMAX eFlash SC20 and it feels reassuringly serious. The steel frame has that "you can drop me, I don't care" vibe, and the finish isn't shouting with cheap plastics or cartoon graphics. It looks like a slimmed-down adult scooter, with a clean black base and turquoise accents that kids actually call "cool" instead of "babyish". There's very little flex in the stem, the deck feels solid underfoot, and hinges and joints click with a purposeful feel rather than a wobbly rattle.

The Jetson Relay goes for a lighter aluminium chassis. It wins the scales by a hair, but you do notice a bit more "toy" in the overall feel. The stem is respectably stiff for such a light scooter, but the combination of smaller hardware, exposed cabling and a narrower deck makes it feel less bomb-proof. It looks good - especially the stealthy black and camo variants - yet when you start bouncing it around, the LAMAX inspires more faith that it'll survive a few years of shared-sibling warfare.

Design philosophy is where they really diverge. LAMAX has clearly worked from the "kid as rider, parent as fleet manager" perspective: robust frame, puncture-proof tyres, simple folding that doesn't need constant adjustment. The Relay feels more engineered around shelf appeal and low weight: nice lines, adjustable bar, simple display, but more obvious cost-cut points in things like buttons, cabling and deck materials.

Ride Comfort & Handling

Neither of these scooters has suspension, so comfort is all about tyres, geometry and how well the chassis soaks up the small stuff. On smooth bike paths or fresh tarmac, both glide pleasantly - light scooters with small motors always feel nimble there. The difference shows up when the surface gets "real world".

The LAMAX, with its slightly larger perforated solid tyres and chunkier frame, damps vibrations better than you'd expect. On average pavements - the odd crack, patchy asphalt, the classic Central European pavement with one tile trying to escape every metre - it stays composed. Kids naturally use their knees as suspension, and the SC20 gives them a stable platform to do exactly that. The deck is low and planted, which helps stability and makes handling intuitive. After a few kilometres of mixed pavements, little riders still look fresh, not like they've just shaken coins loose in their pockets.

The Jetson Relay is more sensitive to surface quality. Those smaller solid wheels and lighter frame transmit more of the road straight into the bars. On perfect cul-de-sac asphalt it feels sharp and agile, almost zippy. Take it onto older sidewalks with expansion joints or rougher concrete, and you can literally hear and see the extra chatter. Kids will tolerate it - they're made of rubber - but if your local environment is anything but "suburban brochure smooth", the LAMAX is the kinder choice on small wrists and knees.

In tight turns and low-speed manoeuvres, both are easy to steer. The LAMAX's fixed bar height gives a very predictable stance; the Relay's adjustable bar helps dial in ergonomics as kids grow, but set it too high and the steering can feel a bit twitchy. Overall, the SC20 feels more like a scaled-down adult scooter, the Relay more like a clever upgrade to a toy kick-scooter.

Performance

Let's be honest: nobody's drag-racing these. We're deep in "safe fun" territory, not "hold my beer" land. Still, how they deliver their modest power matters a lot to how confident kids feel.

The LAMAX's motor feels like it's tuned by someone who actually rides. There's a clear but gentle shove once the kick-to-start engages, building speed smoothly rather than snapping forward. For a child in the middle of the recommended weight range, it picks up pace briskly enough to feel exciting, yet never surprises them. Top speed is capped to a level where a fall is closer to tripping while running than flying off a moped. On flat ground it just hums along, and even lighter inclines are handled without drama, though on anything steep you'll see kids instinctively switch back to kicking. That's fine - the scooter rolls well enough to make "manual mode" perfectly usable.

The Jetson Relay, with its smaller motor, feels more like a powered assist than a true drive on anything but flat. On level pavement and with a relatively light rider, it reaches its modest top speed eventually and then just sits there, content. The three speed modes are helpful for new riders, but after the novelty wears off, most kids lock it in the fastest one and forget the rest. The bigger issue is hills - or, frankly, mild slopes. The moment the ground tilts upwards, the Relay loses enthusiasm fast. On many suburban driveways it will slow to a sad crawl, and heavier kids will often have to help it along with kicks.

Braking performance is similar on paper - both scooters use an electronic brake plus a rear fender brake - but in practice the LAMAX's setup feels more refined. The electronic brake is progressive enough not to pitch kids forward, and the mechanical fender is sturdy and intuitive. The Relay's e-brake works, but combined with a slightly harsher ride and shorter wheelbase, emergency stops feel a bit more "be careful" than "no worries". Kids adapt, but the SC20 gives them a more forgiving safety net.

Battery & Range

This is where the gap between these two really opens. Battery capacity might look like just another line on a spec sheet, but it dictates how the scooter fits into family life.

The LAMAX eFlash SC20 offers a battery that, in kid terms, feels generous. Typical riders on flat to gently rolling terrain can manage proper multi-session days: a long romp around the park in the morning, some neighbourhood loops in the afternoon, and you still don't hit the absolute limit unless your child secretly thinks they're training for Le Mans. Parents report that it's more common to call the ride because dinner's ready than because the scooter gave up. And when it finally does drain, the charge time is short enough that an overnight plug-in turns it around easily for the next outing.

The Jetson Relay's tiny pack, on the other hand, makes itself noticed. For a light child in ideal conditions, you may scrape close to the advertised distance - once. Start adding weight, cooler weather, or even a light headwind, and real-world range drops into the "few kilometres and done" category. That's still fine for quick blasts up and down the street, but on any kind of family ride, the Relay is very much the first to tap out. Charging then becomes a patience game: you're waiting hours to refill what is, by modern standards, a thimble of energy. The combination of short runtime and lazy charging speed is not a highlight.

There's also the storage issue. The LAMAX's slightly larger battery and integrated management system tend to tolerate periods of disuse better, as long as you're vaguely sensible about keeping it topped up. The Relay's tiny pack is far less forgiving when abandoned over winter; plenty of owners have discovered in spring that the scooter didn't just sleep - it died. That's not unique to Jetson, but their pack size and charging behaviour don't help.

Portability & Practicality

On the "can my child or my back handle this" front, both scooters are winningly light. The Relay is a touch lighter, but in practice you won't notice the difference unless you're routinely carrying them up several floors. Both are easy to grab in one hand while herding a child with the other.

The LAMAX's folding mechanism is delightfully simple: drop the bars, click, done. Folded, it becomes a compact, tidy bundle that slides into car boots, under beds or in hallway corners without drama. Because it's happy being used as a regular kick scooter when flat, there's less stress if a ride overruns the battery - you're not stuck lugging a dead weight; your kid just kicks home.

The Jetson Relay folds quickly too, with the stem tucking down against the deck to form a handy carrying shape. The non-folding bars mean it's slightly more awkward in tight storage spaces, but the overall footprint is still small enough for most flats, cupboards and even larger school lockers. Where practicality takes a hit is the combination of short range and power: if your child wants to ride further than the battery allows, you're either pushing or carrying a scooter that's not nearly as nice to kick as the LAMAX once the motor isn't doing its share.

For parents who frequently throw scooters into the car for trips, both are workable. But the SC20's blend of slightly bigger frame, easier manual rolling and better durability makes it the one I'd rather discover in the boot a year later and still expect to work.

Safety

Both brands clearly understand that with kids' e-scooters, safety isn't a bullet point - it's the entire product. They share some important fundamentals: kick-to-start throttles that won't fire from a standstill, dual braking (electronic plus rear fender), grippy decks and integrated lights.

Where the LAMAX edges ahead is in how cohesive the safety package feels. The zero-start behaviour is well-tuned, so the motor doesn't surprise small riders, and the braking balance between e-brake and mechanical brake is particularly confidence-building. The lighting is not an afterthought: the front LED strip is bright enough for visibility in gloomy afternoons, and the rear light doubles as a clear brake indicator. Combined with a very stable, low deck and decent tyre contact patch, the SC20 feels predictable even when a child does something... less predictable.

The Jetson Relay ticks many of the same boxes on paper - kick-to-start, front light, dual braking - but the experience is a bit more compromised. The small wheels are more susceptible to cracks and stones, which is a stability concern entirely separate from electronics. The lighting is functional, but you still really don't want a child on it in the dark; it's more a "see me" light than something you'd rely on to pick out road surface issues. Braking power is adequate, yet emergency stops at top speed feel closer to the limit of what the chassis can comfortably handle.

Neither scooter is waterproof enough for carefree rain riding, and both suffer reduced grip on wet tiles or smooth concrete. But if you're asking which one I'd rather see a younger or less coordinated child on, the LAMAX gets the nod without hesitation.

Community Feedback

Price & Value

On the sticker, the Jetson Relay usually comes in a bit cheaper than the LAMAX eFlash SC20. At first glance, that makes it tempting if you're staring at a long list of birthday demands and a short list of available euros. For a child who'll use it lightly on flat ground, you do get decent fun per euro - at least while the battery is fresh.

The LAMAX asks slightly more upfront, but it gives you more scooter in return: a bigger, more capable battery, sturdier frame, better lighting and a design that stands a real chance of surviving multiple children or a respectable stint on the second-hand market. Over the life of the scooter, that extra initial outlay looks increasingly sensible rather than indulgent. You're buying something that behaves closer to a small vehicle than a disposable gadget.

If you treat both as "two-to-three-year toys", the Relay can look like the budget winner. If you care about long-term reliability, range headroom and passing it down the family tree, the SC20 is the stronger value proposition.

Service & Parts Availability

LAMAX is well-established across Central Europe with a decent service network and parts support. You're not dealing with a faceless marketplace seller; there is an actual brand with a reputation to maintain. For a kids' scooter, that matters - when something does eventually bend, crack or wear out, the chances of getting it fixed instead of binning it are much higher.

Jetson, being a mass-market brand in North America, is very visible but a bit more hit-and-miss once you enter the support maze. Plenty of customers do get warranty issues sorted, but you also see a noticeable chorus of "charger died, support never replied" and "battery won't take charge after winter, no help". Outside their home market, you're often left to your own ingenuity and online forums.

In simple terms: if you want a scooter you can realistically keep running locally without turning into an amateur import-export specialist, the LAMAX is the safer bet in Europe. The Relay is fine while it works; once it doesn't, things get murky faster.

Final Verdict - Which Should You Choose?

If you strip away the marketing and look at how these scooters behave in real family use, the LAMAX eFlash SC20 is the more complete, more trust-inspiring package. It feels sturdier, goes further, brakes more predictably and shrugs off the sort of daily abuse kids specialise in. It's the scooter I'd happily recommend to parents who want one product to see their child through those first proper years of electric riding - and probably then move on to a younger sibling without complaint.

The Jetson Relay has its place. As an affordable, ultra-light, first taste of electric scootering on flat, smooth pavements, it will make plenty of kids grin. If budget is tight and your expectations are honest - short rides, easy terrain, and you're not planning to keep it in a cold garage for half a year - it can be a fun, low-stakes entry point.

But if you're looking for something that behaves like a real scooter scaled down for kids rather than a seasonal electric toy, the LAMAX wins this matchup. It's simply the one that feels built for the long run, not just the first unboxing video.

Based on the scoring, the LAMAX eFlash SC20 is our overall winner. For me, the LAMAX eFlash SC20 is the scooter that actually behaves like a trustworthy little companion rather than a seasonal gadget. It feels sturdier underfoot, keeps going when kids want "just one more lap", and radiates the kind of calm, predictable behaviour that lets parents relax a bit instead of hovering nervously. The Jetson Relay is light, cute and capable of delivering some big first smiles, but it just doesn't have the depth to match - the fun fades as quickly as its battery. If you want your child's first electric scooter to feel like a proper step into real riding, the LAMAX is the one that will keep both of you happier for longer.

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.
