I must confess that I find recumbents interesting, but I don't think I'm intrepid enough to try a two wheeled one. For reasons of economy, general Green principles and a love of old bicycles I use either a bicycle or tricycle to get around; - I don't own a car. However there is one kind of recumbent vehicle that I would very much like to build and try...... the Velocar.
Generally such things were built from whatever was handy during the war period due to petrol rationing and something tells me such times could be on us again before too long.
This is a fascinating article about the Finnish velocars that were built around the war years.
It's not exactly as if I'm short of raw material and I do own a lathe and a MIG welder, - so I guess anything is possible
