who we are
Critical Mass Waltham is a group of local residents promoting safe cycling and advocating for a more bike-friendly and pedestrian-friendly community. Critical Mass organizes monthly communal rides to bike safely as a group, despite Waltham's lack of bicycle infrastructure. The goal is to make everyone feel more comfortable riding on our city streets.
