Welcome

Welcome to BigM  – Having fun riding Mountain bikes together since 2000  

Big M (Brussels International Group of Mountain bikers) is celebrating 20 years of Mountain biking fun in and around Brussels, all over Belgium and surrounding countries. We are a friendly, social and active group of over 100 like minded Mountain bikers.

This site is for members and non-members seeking general information on mountain biking around Brussels and across Belgium and even nearby countries too.
Information includes:

  • Details for applying for club membership … click here
  • Links to local trail descriptions … try this site for fixed routes throughout Belgium
  • General information on organized rides … The O2 Bikers agenda lists info on organised rides throughout the area, including Luxembourg (both the country and the province!) the further south the ride, the hillier it usually is. Liege, Namur and Luxenbourg provinces offer the most challenging riding. Beware that the closer to Brussels the ride is, often the busier it is likely to be.
  • Bike shops we like:

KM10 Located close to the Foret in WaterMael Boitfort – They rent nice bikes in case you need one, they even offer a bike wash service !

Best Bike Convenient location, good selection for bikes and parts.

Swooth Located in Aarschot – these guys simply can fix what others cannot, solve bike issues that other shops won’t bother with. Top notch service,  advice and reasonable rates and timeliness.

The Groups Forum

Members communicate  via our Groups.io forum. We schedule and confirm participation and trade information on trail conditions etc.

June 5th 2021- First Trans Trappist ride 2021 – Rochefort

We kicked off the Trans Trippel/Trappist series by visiting beautiful Rochefort. 12 of us caravaned down from Brussels and safely arrived for a 10AM start. We were greeted by the beautiful cathedral of Rochefort, and chilly yet promising weather. The terrain was rather damp, rocky in places and offered plenty of climbing. And there are … Continue reading June 5th 2021- First Trans Trappist ride 2021 – Rochefort
