While the opening bid and the cost of shipping technically push this bike outside my cheap bike definition I must make allowances for this, one of my favorite bikes of all times.
The BSA folding bike was designed for use by paratroopers. That aside it is one funky looking machine. Plus it has the coolest chainring ever put on a bike.
I wish I had the time and ambition to take on this project right now. But I don’t.
