My grandpa fixed my bike yesterday. He had to use a screwdriver to unscrew the screw. He didn't have a lever to fix it and that was good because he didn't need one! He had to look up the words innclineplane,pulley,wedge,wheel, and axle. Now he knows what those words mean! Anyway he had to fix the gears and once he did I was able to ride my bike down the hill.
