The same fun handling and trail taming performance as its bigger brothers, but in a wallet-friendly specification. This is affordable trail performance at its best. 29 Wheels, 140mm air fork, 1 x 9 drivetrain and a dropper post
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. Sizing follows the Agilometer principle which means most sizes work for most body sizes so that riding style can be factored in. If you want to go fast, take the longer size, for agility, take a shorter size.
