The original Big Trail was designed on the back of a napkin when several UK customers and Merida’s German R&D team chewed the fat about what would make the perfect UK trail bike. The resulting bike received rave press reviews and delighted customers worldwide. Since then Merida’s R&D team have wowed the mountain bike world winning the coveted MBUK Bike of the year in both the Trail bike and Enduro bike categories. Big Trail II takes many of those award-winning learnings: A steeper seat angle (up from 75.5° to 76.5°) puts the rider in an efficient climbing position and shortens the top tube allowing Merida to extend the reach meaning the bike doesn't feel too long when you're pedalling in a seated position but provides plenty of stability on rough terrain. The head angle goes from an already progressive 65.5° to 64.0° and when combined with a large 70mm BB drop (up from 66.5?mm), gives the feeling of ‘sitting in the bike’ rather than ‘on it’ providing plenty of stability and confidence when things get rowdy. The geometry follows the Agilometer principles which means most sizes work for most body sizes so riding style can be factored in. If you want to go crazy fast, take the longer size, for agility, take a shorter size.
