Age 16 or older? Help teach New Yorkers how to ride bikes! When you help a student make biking a part of their daily routine, it isnt just their life that changes. Our volunteers remark time and again on the profundity of witnessing the aha moment when a new biker really gets it , when a recreational rider realizes that a bicycle is much more than a toy, or when a long-time cyclist finally learns how to fix their bike. Volunteer at a Bike New York class and be a part of someones aha moment . Each volunteer shift is 3-4 hours long. Volunteers must attend a mandatory one-hour training session before volunteering at a class.
