The Merida Big Seven 20-3X Bicycle is an entry-level aluminum hardtail designed for riders who prefer the nimbleness and acceleration of 27.5" wheels. These smaller wheels make the bike more agile and responsive, ideal for those who enjoy quick, sharp maneuvers on the trails. Whether you’re navigating tight turns or accelerating out of corners, the Big Seven 20-3X delivers a lively and engaging ride.

Comfort-Focused Geometry: Built with a more upright riding position, the Big Seven 20-3X is designed to reduce strain on your lower back and improve visibility on the trail. This comfort-oriented geometry makes it easier to enjoy longer rides, offering a relaxed position that doesn’t compromise control or performance. It’s perfect for riders who want a balanced mix of comfort and capability.

Smooth Suspension and Reliable Braking: The bike features a 100 mm SR Suntour suspension fork that absorbs bumps and rough terrain, ensuring a smoother ride. Paired with hydraulic disc brakes, the Big Seven 20-3X provides consistent and reliable stopping power in all conditions, giving you the confidence to tackle any trail.

Versatile Gearing: Equipped with a double chainring drivetrain, the Big Seven 20-3X offers a wide range of gears to choose from, making it easier to conquer climbs and maintain speed on flats. This versatile setup ensures you’re always in the right gear for the trail ahead, whether you’re climbing, descending, or cruising.

Classic Hardtail with Modern Features: As an alternative to the 29er Big.Nine series, the Big Seven 20 3X caters to those who prefer the handling characteristics of 27.5" wheels. The bike’s latest aluminum frame features slim tube shapes and a more relaxed geometry, creating a modern look and feel. The shorter top tube and higher head tube enhance comfort and trail visibility, making this bike an excellent choice for both new and experienced riders.

Crafted with Expertise: Manufactured in Taiwan, the Big Seven 20 3X reflects Merida’s half-century of experience in bike production. This hardtail is the result of meticulous craftsmanship and modern frame technology, offering a ride that’s both comfortable and reliable.
