MassBike is the statewide bicycling education and advocacy organization. Membership entitles you to a 10% discount at bike shops and B&Bs across the state, and makes you eligible for a 10% auto insurance discount. Most importantly, it supports the advocacy work that MassBike does, including major 2004 wins such as dramatically expanding the hours that bikes are allowed on the MBTA subway, and passing a law requiring the RMV to update the Driver's Manual to include bike safety information
