The Bike Detectives (2008)

Young Leon is new in town and wants to fit in. He tries to join a local club of self-styled sleuths called the “Mountain Bike Detective Club,” but he’s got a problem—his bike isn’t cool enough for the group and he doesn’t have enough money for a better one. That’s when a mysterious helmeted figure on a motorcycle approaches Leon with an offer to make some money, and Leon just can’t refuse.
