Final Pedal.jpg

A bike is a very useful mode of transportation that many people in first-world countries take for granted. There has been a goal set to create a cheap bike using primarily 3D printed parts. This bike pedal is a good prototype for what the possibilities are for this project. This pedal is fully 3D printed and clips together around a bar/axle. The goal is that this pedal would be easy to switch out and allows for rotation around the axle but not in other directions. This is still a rough prototype and would need more work to be implemented fully onto the bike.

Possible additions to bike pedal:

  1. Add screw attachment at the end of the axle
  2. Develop more secure clips (these were tough to model and print)

Bill of Materials[edit | edit source]

  1. Plastic Filament (PLA preferred)
    1. All files (FreeCAD and.stl) can be found on Youmagine at:

Tools needed[edit | edit source]

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Knife of some sort to clean up parts

Skills and Knowledge Necessary to Make the OSAT[edit | edit source]

  • Be sure you are able to load an STL into a slicer and orient it the correct way
  • Basic understanding of bike pedals

Technical Specifications and Assembly Instructions[edit | edit source]

Common Problems and Solutions[edit | edit source]

  • Don't forget to put support everywhere on the pedal halves. Be sure to select "Everywhere" instead of "Touching Buildplate".
  • Ensure all pieces are printed with the orientation shown.

Cost savings[edit | edit source]

  1. The cost to print the full pedal is approximately $2.50
  2. Walmart sells two pedals for $7.99 [1]
  3. Savings are $3.00 per two pedals which is savings of 37.5%
