FREE RIDE
Follow your curiosity.
Explore the mountain map, find six hidden places and follow connecting routes. Look for marked gap lines, then take a summit lift for another descent.
FIND YOUR BALANCE
Make the landing.
Shift your weight with the stick, control spins and somersaults, and choose your front or rear brake balance. Crashes keep rolling. Let the wreck settle, then get back on the bike.
YOUR NEXT RUN
Keep a trail journal.
Work toward nine riding, air and exploration goals to earn rider kits. Progress and best lines stay on your device.
