How to Build a Mountain Bike Berm: A Comprehensive Guide to Creating Perfect Turns on Your Trail
A mountain bike berm can be built by shaping a dirt pile or existing terrain into a banked turn. The berm should be angled at approximately 45 degrees and compacted tightly to prevent erosion. Rocks or logs can be added to the inside of the berm to support it and add additional challenge. The berm should be tested and adjusted as needed for the desired level of difficulty and performance.
