Step 1
Pedal the bike and shift the gears on the bicycle to the high gear. This moves the chain to the smallest gear cog on the rear wheel.
Step 2
Loosen the tension screw on the rear brake shoes to open the brake.
Step 3
Grab the derailleur with your right hand and pull it back while rotating the quick-release lever to the open position with your left. The derailleur moves the chain from one cog to the other when shifting the gears.
