My wife brought a second hand CoPilot Limo seat for her bike which came with a Blackburn EX1 rack.
I have just tried to fit this but came accross a hopefully minor problem. Her bike is a Giant Revel 3 - this has two rear dropout eyelets for the bottom part of the rack but no eyelets underneath the seat to bolt the silver rods onto. We live in Brussels and I went to a local bike shop to see if they could help, but the guy just shrugged his shoulders and said that there was no solution other than to buy another bike seat that clips onto the metal frame.
I've been reading about using p-clips instead but just read on another website that they can slip. I need too obviously find the safest solution.
