Overview: A series of purse snatchings involving motorcyclists frustrates the LAPD, as they cannot follow them down the off-road trails they take. Reed holds a community meeting with the various motorcycle clubs, and the leader of one club challenges Malloy to a dirt bike race. Reed teaches Malloy how to ride a dirt bike, and while Malloy loses the race, he gains the respect of the club's leader, who helps them apprehend the suspects by blocking their escape route.
