Belgium sea front, not sure where, in the 1950s. This is great grandma or my step mother on the crazy bikes in a velo drome. Why do I post this? Because we have about 80 wacky crazy bikes that we can take to events and we take selections as part of our bigtopmania Festival children’s area packages. Wacky bikes! Crazy bikes! Cycle circus ! They are available stand alone for many events such as cycling events or cycling festivals . Children and adults love playing on them.
