Description

These are designs in Tinkercad for the frame and look of the mini bike.

Details

I have 3-D printed the mini-bike. The 3-D model can seen in the gallery of pictures. The model allows me to stress test certain parts of the bike. For example: the front fork of the bike is a stress point between itself and connection to the rest of the frame.

In light of the model and welding opportunities, I will be using steel as the metal of choice for this build. I will mainly be gathering old bicycle frames, chopping them up, and re-welding a frame.
