Read this excerpt from Leah Missbach Day’s foreword to Wheels of Change . Freedom comes in many forms. For Mary Lewanika, a bicycle provides freedom from social oppression. A bicycle can cultivate independence. In Wheels of Change , Sue Macy quotes Ellen B. Parkhurst in Washington's Evening Times , "A girl who rides a wheel is lifted out of herself and her surroundings." That was true in 1896, and incredibly, it remains true in places around the world today.
