Introduction: 8020 Chopper

8020 is an industrial prototyping extrusion made from aluminium. I used it here to construct a chopper by joining the extrusions with water-jet cut plates of 1/4inch aluminum.

Step 1: Choose and Design the Type of Bike Frame You Wish For

Here are some of the options we designed at an MIT IAP class in 2003.

The CAD files are all included in this step.

Step 2: Choose the Connecting Parts From the Part Library or Design Your Own.

These parts will be cut from 1/4 or 1/2inch thick aluminum plate using a water-jet.

those rectangular extrusion things can be bought from a company with some german name. They're a little expensive though. People use them alot in robotics.

80/20 also makes them! contact: www.8020.net

what program did you use to make the drawings? i have never seen a .dxf file, autocad is .dwg

Autocad will load DXF files. It's a very popular import/export format among many different software packages.

Where do you need to open the links ?

hi,these don't seem to work on any cad file reader like CAD viewer,and i also tryed 2 more all give an error

Congratulations!!! That's awesome. Now can you build the Recumbent Bike out of 8020? I hope you can do it. I wish you the best luck on your next 8020 projects. Bob Jackson

I'm building a chopper for my homecoming parade and I need a fat wheel for the rear where can I get one?

Love it :D
