The classic with collapsible bags. The base of the Fold Boxes is lined with extremely tough tarpaulin in order to prevent wear from the basket struts. The side straps can be fixed to ensure optimal protection against the elements. When collapsed the boxes require very little storage space. Suitable for almost all delivery bicycles. The All-In-One version with carrying straps can also be used in the Post-Caddy and all standard mail trolleys. One bag - two systems.
