I made the first move in building the Plycycle MK2. I bought a fresh sheet of plywood. I made the trip to Avon Plywood, who are the main retailer of ply near Bristol. They store it flat and have a huge choice. This time I went for 9mm long grain birch ply. The first Plycycle was made from 12mm birch, and this worked very well, but having looked it over and ridden it a lot now, I think 9mm birch ply will be strong enough and be lighter into the bargain.
The Avon Ply warehouse, they got alot of ply.
I think it is great that a sheet of wood can become a bike.
