We have lots of pictures- some too large to scan- and various instruction handouts. We try to spark ideas and let people run with them. We just supply endless bike parts.

The main design, easily modified, is:

-2 wheels, same size, in bike forks, with bike fork parallel to ground

-stem comes out of each fork, with a top tube joining stems

-another stem comes out of top tube on left side

-another piece of bike tubing extends forward

-another stem attaches to extended bike tubing

-a seat post goes in stem and contains hitch to chain stay

-hitch can be piece of tire (bead left in) that wraps around chain stay and is anchored with a bolt and wing nut, or a shopping cart wheel caster, or??

-hole can be drilled and pin inserted where twisting may occur at stems

Other trailers have been made with crutches, bed frames, shopping carts, haywagons, and so on.

Hey Bob,

Care to share the instructions for trailer building? We'd like to teach

a

workshop on how to build a trailer from bike parts, and are looking into

a

few different designs.
