BRC: Made specifically to fit Catrikes, the framebags make use of the space behind the seats. They come  as complete pairs. The volume is 8 liters for each side.

ARKEL: These bags are specifically made for the Catrike Expedition, Road and Speed. They are made right here in Sherbrooke, QC, Canada from 600 denier polyester fabric with foam and high density polyethelene stiffeners. They are sold as sets and fit snugly on each trike. No rack necessary! The designs are made to carry from the frame and require absolutely no other hardware.

Important Note: This bag will not fit some of the newer models with the adjustable seat. Check chart below for compatibility.
