This classic 1970's style chop was named and built by Enzo and Nathan (father and son team) from an old mountain bike that was found laying in the mud at the city dump.
Instead of the extended front forks, this chopper is roughly styled after the classic Raleigh Chopper bicycle with the straight frame and tiny front wheel. This project requires no extra tubing in the frame, and except for a few small add-ons, only requires cutting and welding two frame tubes.
Any mountain bike with 26 or 24 inch wheels can be used for this project. Besides replacing the seat and handlebars, you will only need a front wheel of any size smaller than the original rear wheel. A 16-inch wheel was chosen for this build.
All welding processes produce fumes and gases to a greater or lesser extent. Galvanized steels produce added fumes from the vaporized zinc coating. Fumes from welding galvanized steel can contain zinc, iron and lead. Use precautions, including high-velocity circulating fans with filters, good ventilation, air respirators and fume-extraction systems.

The overall condition of this bike was fairly good considering it sat in a mud hole at the local dump, and was probably run over a few times by the bulldozer guy. This is a good thing, since we will be using everything but the front wheel, seat and handlebars.
