The Spacelander is a streamlined Monocoque fiberglass bike designed by British-born designer Benjamin G. Bowden in 1946. It took fourteen long years before it went into full production in 1960. It was only a short run. The $89.50 pricetag was too high at the time and tastes had changed. Also, bike manufacturers considered it too exotic for mass marketing. Nowadays, these extremely rare beauties can fetch up to $15,000 in good condition!
