Tho sent in his DIY fold-a-bike, he writes – “Here’s my folding bike that I built years ago from a cheapo small frame bike. The bike now has 20″ wheels, and the frame size is equivalent to about 17″. It was made by starting with the 19″ frame, cut apart with a hack saw, shape with hand held grinder, and then braze weld back together using nickel-silver rods and oxy-acetylene torch. The bike weighs 21.5 lbs, with no front derailleur and only front brake.”
