NBA superstar LeBron James surprised dozens of teens at a YMCA in New York City on Tuesday. The Los Angeles Lakers forward, who loves riding bikes, is partnering with ride-sharing app Lyft to provide thousands of youth with free access to bicycles. James stood in front of more than 50 kids at YMCA Harlem to announce his new endeavor –– and a cause dear to him while growing up in Akron, Ohio.
