A record of my efforts to construct a python recumbent bicycle, also known as a moving bottom bracket (MBB) or pivot steer bicycle.

A long gap, problems and Sarah learns to ride
Work finished on the Python some months ago, though there are still many details to add.
Sarah and I tried to ride it and failed. The bike rusted and Sarah found the cranks too long. The handlebar mount broke.
Recently, Sarah tried more successfully to practice, so I stripped the rust with a wire brush on an angle grinder, welded some better handlebars and applied zinc anti-rust primer paint to the frame. Sarah is now at the point of riding confidently as long as steering doesn't need to be precise.
