I visited my local bike shop today to have a spoke replaced and wheel trued. Rapid Transit has been the shop I've used since moving to Chicago four years ago. This tricycle might belong to one of the employees. I know I've been in before when one of their bikes was hanging from these ceiling hooks. Of course it could also be a repair job waiting to be picked up. I'd hate to have to take this thing down to the basement and back up, where they hold a lot of their repairs.
