Orbea MX 24 XC

About the Orbea MX 24 XC

The Orbea MX 24 XC is a proper junior hardtail that treats young riders with respect. Rather than scaling down an adult bike and hoping for the best, Orbea has built a machine that acknowledges the realities of smaller hands, shorter inseams, and developing skills. The 2025 model carries forward the brand's commitment to lightweight aluminium construction and thoughtful component choices, delivering a bike that won't anchor a child to the ground or overwhelm them with complexity. It's designed for riders between 125 and 150 cm tall - roughly eight to twelve years old - who are ready to leave the tarmac behind and explore what lies beyond the kerb.

At 11.4 kg, the MX 24 XC sits comfortably in the realm of bikes that children can actually manoeuvre. You'll notice the difference when they're hoisting it over a log or wrestling it back upright after a tumble. The frame is built from 6061 aluminium with internal cable routing, so it looks tidy and the cables stay protected when the bike inevitably gets dropped or leaned against a tree. A 50 mm SR Suntour XCT-JR fork up front takes the sting out of roots and rocks, while the 1×7 Shimano Altus drivetrain keeps things simple: one shifter, seven gears, no front mech to confuse or jam. V-brakes handle stopping duties, and while they lack the raw power of discs, they're easy to maintain and offer plenty of bite for the speeds and weights involved.

This is a bike that encourages exploration. The Kenda Booster tyres are wide enough to grip loose dirt and absorb trail chatter, yet roll efficiently on tarmac when the route home involves a stretch of road. Fender and carrier mounts mean you can add mudguards for winter rides or a rack for carrying a packed lunch to the woods. It's a machine built to grow with a rider's confidence, whether that means tackling the local bridleway, joining a family ride on gravel byways, or simply bombing around the park with mates.

Orbea MX 24 XC geometry

Orbea's MX Compact Geometry is tailored to smaller riders, balancing stability with the nimbleness that makes trail riding fun rather than frightening. The frame positions young riders in a slightly upright posture, which opens up the chest for easier breathing and gives a clearer view of the trail ahead. That upright stance also makes it simpler to shift weight back when the path drops away or forward when climbing a rooty bank. The head angle is relaxed enough to inspire confidence on descents without feeling sluggish when the trail tightens, and the chainstays are short enough to keep the rear wheel tucked in close, so the bike pivots willingly around corners.

Standover height is generous, allowing riders to plant both feet flat when they stop - a small detail that makes a huge difference to confidence. The reach is proportioned so that smaller arms can comfortably grip the bars without stretching, and the stack keeps the cockpit from feeling cramped. When a child is properly positioned on the bike, they can react quickly to trail features, shift their weight intuitively, and ride with the kind of fluidity that builds skills rather than bad habits. The 24-inch wheels strike a sweet spot: they're large enough to roll over obstacles smoothly and maintain momentum, yet small enough to keep the bike feeling agile and responsive.

Component choices & upgrades

The stock build on the MX 24 XC is already well sorted for its intended audience. The Shimano Altus rear mech and SL-M315 shifter are reliable workhorses that handle mud, dust, and the occasional crash without drama. The 14-34t cassette paired with a 36t chainring offers a sensible range: low enough for steep climbs, tall enough for flat-out sprints on the way home. The SR Suntour fork's 50 mm of travel is modest by adult standards, but it's tuned for lighter riders and does a solid job of smoothing out trail chatter without adding unnecessary weight or complexity. The coil spring is simple to maintain, and the preload adjuster lets you dial in a bit more support as the rider grows or gains confidence.

If your child is progressing quickly and spending more time on technical trails, a few targeted upgrades can extend the bike's capability. Swapping the V-brakes for mechanical disc brakes - if the frame's IS disc mount is utilised - will deliver more consistent stopping power in wet conditions and give a bit more modulation on steep descents. A set of grippier tyres with a more aggressive tread pattern can transform the bike's traction on loose or muddy trails, though the stock Kenda Boosters are perfectly adequate for general riding. A shorter stem or wider bars might suit a rider who's outgrowing the stock cockpit, but these are refinements rather than necessities. The beauty of the MX 24 XC is that it works well as delivered, and any upgrades should be driven by the rider's evolving skills and terrain demands rather than a sense that the stock kit is inadequate.

Where the Orbea MX 24 XC excels

The MX 24 XC is outstanding at introducing young riders to proper off-road riding. It's light enough that children can handle it confidently, yet robust enough to withstand the inevitable knocks and tumbles that come with learning. The bike shines on bridleways, forest trails, and gravel byways - anywhere the surface is varied and the pace is exploratory rather than flat-out. The suspension fork and wide tyres soak up bumps and roots, so riders can focus on line choice and balance rather than being rattled off course. The simple 1×7 drivetrain means less time fiddling with gears and more time riding, which is exactly what builds confidence and skill.

It's also excellent for family rides where the terrain mixes tarmac, gravel, and light singletrack. The bike rolls efficiently on smooth surfaces, so it won't hold a child back on the road sections, yet it has the grip and compliance to handle rougher ground when the route turns adventurous. The upright geometry and junior-specific contact points mean longer rides are comfortable rather than exhausting, and the fender and carrier mounts add practicality for year-round use.

Where the MX 24 XC is less ideal is on genuinely technical terrain that demands aggressive descending or sustained steep climbs. The V-brakes, while adequate for most riding, lack the power and modulation of hydraulic discs when speeds ramp up or conditions turn wet. The 50 mm fork is fine for smoothing trail chatter, but it won't absorb the impacts of larger drops or rock gardens the way a longer-travel fork would. This isn't a bike for junior downhill racing or enduro aspirations - it's a capable, confidence-building hardtail that excels at the kind of riding most children will actually do.

Orbea MX 24 XC FAQs

What is the ideal rider height for the Orbea MX 24 XC?
The MX 24 XC is designed for riders between 125 and 150 cm tall, typically children aged eight to twelve. Standover height is generous, so most riders in that range will be able to plant both feet flat when stopped. If your child is at the lower end of the height range, check that they can comfortably reach the bars and operate the brakes and shifter without stretching.

Does the Orbea MX 24 XC have disc brakes?
No, the 2025 model comes equipped with junior alloy V-brakes as standard. The frame does feature an IS disc mount, so it's possible to upgrade to mechanical disc brakes if you want more stopping power or better wet-weather performance. For most young riders and typical trail riding, the V-brakes offer adequate control and are easier to maintain.

How much does the Orbea MX 24 XC weigh?
The complete bike weighs approximately 11.4 kg. That's light enough for children to handle confidently, whether they're lifting it over an obstacle, pushing it up a steep section, or simply manoeuvring it in the garage. The lightweight aluminium frame is a key part of keeping the overall weight manageable.

Is the Orbea MX 24 XC good for trail riding?
Yes, it's very well suited to trail riding. The 50 mm suspension fork smooths out roots and rocks, the 2.20-inch Kenda Booster tyres provide good grip on loose surfaces, and the geometry is stable without feeling sluggish. It's designed for bridleways, forest trails, and gravel byways - the kind of terrain where young riders build confidence and skills.

What are the gear ratios on the Orbea MX 24 XC?
The bike runs a 1×7 drivetrain with a 36t chainring up front and a 14-34t cassette at the rear. That gives a low gear that's manageable for steep climbs and a high gear that's tall enough for flat-out efforts on the flat. The range is sensible for varied terrain, and the single chainring keeps shifting simple and reliable.

Can you put wider tyres on the Orbea MX 24 XC?
The frame is designed around 24×2.20-inch tyres, and there's likely a bit of clearance beyond that, but you're working within the constraints of a 24-inch wheel and junior frame. If you want more grip or cushioning, you could experiment with a slightly wider or more aggressive tread pattern, but don't expect to fit anything dramatically larger without risking rub on the fork or stays.

What are the alternatives to the Orbea MX 24 XC?
Within Orbea's range, the MX 24 Trail offers a step up with disc brakes and potentially a more trail-focused spec. Cross-brand, the Trek Precaliber 24 is a direct competitor with similar gearing and suspension, while the Specialized Riprock often comes with wider tyres and a more rugged feel. The Woom Explore 5 is lighter and more refined but typically pricier, and the Hoy Bonaly 24 is another lightweight option worth considering. The Frog MTB 24 is known for quality and fit, though availability can vary.

Is the Orbea MX 24 XC suitable for a beginner?
Absolutely. The lightweight frame, simple 1×7 drivetrain, and confidence-inspiring geometry make it an excellent choice for children who are new to off-road riding. The suspension fork takes the edge off bumps, the V-brakes are easy to operate, and the bike's overall balance encourages rather than intimidates. It's a machine that grows with a rider's skills rather than overwhelming them from the start.
