Abstract
Bicycles are a mode of transportation used throughout the world. There are 3 pieces of a bicycle that interact with the users. They are the seat, handlebar grips, and pedals. I set out to design and improve the bike grips that attach to the handlebars. I based my design off of Ergon GP1 Grips to be easily printed out of TPU or any other flexible filament. I believe this is appropriate for any user that has access to a 3D printer from people in 3rd world countries that use their bike out of necessity to someone that uses their bike for entertainment. This fulfills the need for a comfortable cheap alternative for current bike grips on the market. Below is a picture of the bike grips attached to a set of standard handlebars.
