A growing Facebook thread Thursday discusses the long-standing issue of bicycles on the sidewalk. The range of opinions about why it’s right or wrong for bikes to be on the sidewalk is well-known. It is against City legislation for bicycles to be ridden on sidewalks. We hear again how they threaten pedestrians and are hard for motorists to see when a rider unexpectedly appears from a driveway ramp or at a corner. Alternatively, some argue the roads are dangerous and the only safe place for a cyclist, especially a child, is on the sidewalk.
