Anyone know where to get blueprints for a quadracycle-four wheel adult bike-I would like my hubby to build me1 - bike blueprints

Speedster America have both plans and kits for some very interesting quads. Some are constructed of PVC with hand tools and recycled bike parts. See the link below.

Sometimes there are announced plans to e-Bay, but some of them are just copies of the mechanics of old magazines.
