Apex A400 24″ Mountain Bike

Apex A400 24″ MTB for Growing Riders

The Apex A400 24″ MTB is built for young riders who want a bicycle that can handle more than smooth pavement. With a lightweight frame, 24-inch wheels, front suspension and multiple gears, the A400 gives growing cyclists a capable platform for everyday riding and suitable light trail adventures.

The 24-inch wheel size is well suited to young riders who have progressed from smaller bicycles and are looking for more capability. It provides a useful combination of stability and responsive handling, making the bike suitable for parks, paths and recreational off-road riding.

50mm Suspension Fork

The front of the A400 is equipped with an Apex 24-inch suspension fork offering 50mm of travel. The suspension system helps absorb bumps and uneven sections of riding surface, which can make light trail riding and rougher paths more comfortable.

Chaoyang 24 x 2.1-inch MTB tyres complement the suspension setup. Their wider profile gives the bike a practical footprint for mixed riding conditions while maintaining the compact proportions expected from a youth mountain bike.

8-Speed Gearing

The A400 uses an L-Twoo A3 8-speed drivetrain with a 34T crankset and 13-28T cassette. This provides young riders with a selection of gears for adapting to changes in terrain.

Multiple gears can also help young cyclists develop their understanding of shifting and cadence as their riding experience grows. The rear derailleur and trigger shifter provide a straightforward way to select gears while riding.

Mechanical Disc Brakes

Mechanical disc brakes with 160mm rotors provide the braking system. Disc brakes are a useful feature for a youth MTB because they offer controlled braking performance across a range of riding conditions.

The A400 also uses alloy double-wall 24-inch rims and an Apex Sport saddle. Together, these components create a practical specification for a young rider who wants a more capable bicycle.

Whether you’re looking for a 24-inch mountain bike for everyday cycling or a youth MTB for weekend adventures, the Apex A400 offers a balanced combination of suspension, gearing and braking performance.
