Merida Big.Nine 300 IV1 2025 Bicycle is built for riders who want a capable aluminium mountain bike for off-road rides, fitness trails and everyday adventure. Its 29er wheels roll smoothly over rough surfaces while helping the bike hold speed with confidence.

Comfortable MTB Geometry: The double-butted aluminium frame is designed with a slightly more upright riding position compared to Merida’s race-focused models. This helps reduce strain on the lower back and gives better visibility on trails, making the ride more comfortable and controlled.

Air Suspension Control: The 100 mm air suspension fork adds comfort and control when riding over bumps, uneven paths and light trail sections. It helps the front wheel stay composed, giving riders more confidence when exploring off-road routes.

Wide Gear Range: A double-chainring 10-speed Shimano drivetrain provides a broad gear range for climbs, flats and varied terrain. Paired with powerful hydraulic disc brakes, the Big.Nine 300 gives riders dependable shifting and strong stopping power.

Merida Big.Nine 300 IV1 2025 Bicycle is a practical 29er hardtail for riders who want comfort, control and off-road-ready performance.
