The Merida Big Trail 500 came about in a pretty straightforward way: a handful of UK dealers sat down with Merida's R&D chief and talked through what an ideal UK trail bike would actually look like.
That conversation became the original Big Trail, and this second iteration has taken everything that worked and pushed it further.
It's a Merida mountain bike built with British trails in mind, which makes a genuine difference. The progressive geometry pairs a steep 76.5° seat angle with a slack 64.0° head angle, so you get efficient climbing without sacrificing the stability you need when things get loose, steep, or technical on the way back down. Anyone who has ridden proper UK trail centres or moorland descents will know exactly why that balance matters.
Sizing follows the Agilometer principle, meaning there's real flexibility baked in. Most sizes suit a range of body sizes, so your riding style can actually shape your choice.
Want to rail corners and go quick? Size up. After something more nimble and playful? Size down.
It's a sensible approach that takes the guesswork out of getting the fit right.
What's on the bike:
- 140mm air fork, well suited to the varied terrain you'll find across the UK
- 29" wheels for rolling speed and confidence over roots and rocks
- 1x transmission, keeping things simple and reliable on the trail
- Dropper post as standard, which should be on every trail bike at this level
