BIG TRAIL 300
Merida
Trail
BIG TRAIL 300 is an alloy trail mountain bike (2025), by Merida, part of the Big family. It is a strong match for riders who want a more active, performance-leaning off-road feel, with a setup that gives you a sporty, active riding position, while being well suited to natural trails and mixed off-road terrain. Metric-wise, it stands out for strong value-for-money versus many similar bikes, strong climbing friendliness for sustained uphill riding, and good fit flexibility for dialing in rider position. The main limitation versus more focused builds is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds. If this looks close to what you want, compare this bike on MatchBikes.com against similar models.
