What "suspicions" the from what I read the only "obvious" thing that the individual did wrong was riding his bike in a "high crime area:"

At the hearing on J.C.'s motion to suppress the physical evidence, the arresting officer testified that upon seeing J.C. riding his bike in “a high crime area,” he and the officer with whom he was riding “pulled along and asked to approach [J.C.].” There is no indication in the record of how J.C. responded.

Granted the rider as it turns out because of the suspect/illegal search is/was engaged in an illegal activity, but how does riding one's bike in a "high crime area" constitute probable cause to stop/detain and search said rider? Doesn't there need to be more cause then riding "in a high crime area?"
