Get started on your mountain bike journey. The BIG.NINE 40 uses Merida's latest aluminium frame to give a tough but lightweight base for high-value, high-performance kit. With updated geometry and a 120 mm air-sprung fork, it's a confident off-road machine that packs in versatility for everyday use, while Shimano's CUES 1x9-speed drivetrain and the hydraulic disc brakes are simple but effective.

Merida's classic XC hardtails are the backbone of their range and showcase the enormous wealth of experience and knowledge they have gained in over half a century of bike production and manufacturing.
