Some of my best memories come from driving go-carts when I was a kid. With the use of the UF-25H Universal Fabricator I was able to build the items seen in the first image below which my grandkids had a lot of fun with. The pedal bike was made out of 3/4" round tubing on the #1-ORB. Making pedal bikes and pedal cars is a business that one could certainly specialize in. These projects also give kids the chance to away from video games and get some much-needed healthy exercise.
