the company 

Beicio Mynydd Dyfi Mountain Biking.cic is a community interest company formed by volunteers to continue to operate, maintain and develop facilities for mountain biking in the Dyfi area. Our mission is to protect and promote existing tracks in order to provide a network of mountain bike trails among the best in the UK.  

your trails

Dyfi Mountain Biking is continuing work which started with the Mach Trails in 2001, and expanded with the legendary Climachx in 2005. In 2018 we hosted four dig-days to maintain the trails, and have more planned for this year. See our Facebook page for updates.

our future

We are working with NRW to pioneer new processes which will open up the Dyfi Forest beyond the familiar trail centre model. New trails will split from the Climachx to offer more challenging variations, making them ideal for the experienced rider who is looking to explore an area, rather than just follow arrows.

Over the course of 2019 we also intend to re-develop the Mach 1,2,3 cross country (XC) trails. We have commissioned new signage and mapping, and hope to roll this out over the summer.
