There is a thrust ball bearing attaching the seat, because the height of the seat is adjustable. This is a bushing attaching the handle bars to the bike, so the rider can steer. These are bushings which attach the spring to the bike and rotate to absorb the shock. This is a bushing on the handle brake, allowing it to rotate when squeezed. Each wheel has a radial ball bearing, so that they can spin freely. here are radial ball bearings on the pedal and where the pedal attaches to the bike, because both of these rotate easily. This is a radial ball bearing on the gears, which allow the gear to rotate easily. This is a bushing on the brake pad, which allows the brake pad to rotate and stop the wheels. Enginerds Transmission On the bike there were 9 sprockets: 3 where you pedal the bike and 6 on the back wheel. Although there were 9 sprockets, there were only 8 different amounts of teeth on them. A sprocket on both of them had 24 teeth. The number of teeth on the sprockets were 14, 16, 18, 21, 24, 28, 36, and 42. The possible gear ratios as ratios and as decimals are listed
