Big Trail 300 2026

The Big Trail 300 is a fun-packed and capable hardtail trail mountain bike. With its progressive geometry, long-travel 140mm fork, and grippy 2.4" wide 29er trail tyre, it's perfect for exciting trail sessions and challenging all-day rides over rough terrain.

The original Big Trail concept was the result of a few UK dealers discussing the ideal UK trail bike with the Merida R&D chief - simple: 140mm air fork, 29" wheels, 1 x transmission and a dropper post. 

Now in its 2nd iteration Big Trail is a fun-packed and hugely capable trail bike. Its progressive geometry combines a steep 76.5° seat angle with a slack 64.0° head angle giving great climbing characteristics and plenty of stability when the terrain gets steep or rough.
