Mayor Rahm Emanuel announced Divvy, Chicago’s bike share system, is partnering with the Chicago Blackhawks to celebrate the start of upcoming NHL hockey season with five Blackhawks-themed Divvy bikes, and giving riders the chance to win great prizes from the team.

The release of the bikes also begins the #BLACKHAWKSBIKE contest, with prizes awarded each week through the end of October. Spotting one of these bikes and posting a photo on social media with the hashtag #BLACKHAWKSBIKE makes Chicagoans and visitors eligible to win great prizes.

Each week, Divvy and the Blackhawks will tally the number of trips taken on each Blackhawks bike. The results will be posted online so fans can see which numbered bike is getting the most rides. Get more information at DivvyBikes.com/blackhawks and blackhawks.nhl.com/blackhawksbike.
