How to Change the Gears on a Mountain Bike: A Step-by-Step Guide
To change gears on a mountain bike, use the left shifter to move the chain between the front chainrings, and use the right shifter to move the chain between the rear cassette cogs. Shift up by clicking the shifter away from you, and shift down by clicking it toward you. Always ease up on the pedals when shifting, and adjust your speed and gear combination to match the terrain and incline you are riding on.
