Young boy next to a bike that's turned upside down is handling a socket wrench set that is set next to the bike.
A boy is trying to perfect his racing bike's gear settings so he can win the race.
A bike doesn't have to be a racing bike. Just because a boy is working on a bike doesn't mean it is his bike. A boy using a socket wrench set on a bike may not be trying to perfect the bike's gear settings. A boy may not be working on a bike so he can win a race.
