The Merida Big Trail 300 didn't come from a boardroom. It came from UK dealers sitting down with Merida's R&D chief and working out what an ideal UK trail bike actually looks like. That's a rare starting point, and you can feel it in the result.
Now in its second iteration, this Merida mountain bike has been refined into something genuinely well-suited to the kind of riding most British trail riders actually do, technical, unpredictable, and rarely forgiving of a bike that can't keep up.
Geometry that earns its keep
The numbers on this Merida MTB are worth a moment. A steep 76.5° seat angle puts you in a strong climbing position, while the slack 64.0° head angle gives you the stability and confidence when the trail drops away or the ground gets loose beneath you. It climbs well, descends better, and doesn't ask you to pick one or the other.
Sizing that suits your riding style
The Big Trail 300 follows Merida's Agilometer sizing principle, which means most frame sizes accommodate a range of body sizes, so you can factor in how you ride.
Want to push harder and carry more speed? Go longer.
Prefer something more flickable and agile on tighter trails? Size down.
It's a genuinely useful approach that puts your riding style at the centre of the decision.
