Make Mario and Luigi Proud! - PVC Bike Cart | Instructables
This is fashioned after the bamboo bike trailer, with the addition of a seatpost mount and PVC instead of bamboo. I used the instruction for the wheel mounts, something I need to modify in the future to accomodate heavier loads to relieve axel flex. The PVC is 1" and the trailer bed is 12" wire shelving left over from a home remodel. The wheels are 20" front wheels with bolt-on axel. These are about $24 a piece unless you run a bike shop..hint,hint. The seatpost mount is made by TRAIL-GATOR.com and sells for around $15. My total investment was around $60 for this brand new trailer.
