The Bicycle Thief

Corky resolves to enter a 50k bike race despite his father's objections, and makes friends with another biker who is epileptic. He bought a brand-spanking new bike from a guy in the bike store who had a crush on Paige. The bike was stolen, and Zoe, seeing Corky's heartbreak, stole him an almost identical one. The truth wins out, though, and all gets cleared up in the end.
