Hitch 'em up.

Saris' Towable T-Rax Base allows carrying a 2- or 3-bike 200-Series Saris T-Rax bike rack along with a trailer, camper or boat. It's retrofittable to existing 2-bike B.A.T. racks or any 3-bike or less 200-Series T-Rax model with a 2-inch receiver (depending on clearance). It has a towing capacity of 2,500 pounds, too.
