ABSTRACT:
A retractable fender for a bicycle which includes a strip of flexible resilient material such as spring steel which is fixed at one end to a connector which is, in turn, mounted to a fixed structure of a bicycle such as the seat adjusting bolt or the bolt for one of the wheel brake calipers has two normal states. In a first state, the strip is self-biased into a helical coil configuration and the strip is straight between the side edges of the strip. In a second state, the strip is longitudinally straight and rigid and self-biased into a bowed configuration between the side edges of the strip. The fender is rendered to its second state by uncoiling the strip so that it is fully extended and allowing the strip to assume its natural bowed configuration so that the strip is effectively locked into a straight rigid configuration. The strip is again retracted by making the free end of the strip flat so that the strip returns to its normal helical coil configuration.
