Rob, a fabricator by trade, has a pretty sweet build he shared with us after buying a spring for the project:
I help put on a fundraiser for a non-profit called Kammys Kause (4p-supportgroup.org for more info). So along with making the event happen I make something to auction off. I was offered an old radio flyer tricycle to restore and found out I could basically buy all the parts and put it back to new. Didn’t think that was cool so I decided I would build one. This bike started as a ’96 GT Vertigo. I stripped the paint and cut the rear off, polished out all the chrome and built the rear swing arm. It has a 1/2″ solid stainless rear axle with the left side machined down and threaded 3/8 x 26 to fit all the nuts and bearing nuts so the left wheel free spins. It’s keyed for the drive sprocket and keyed for the hub I made so the right wheel is fixed to the drive shaft. I had a buddy replicate the font style of the original graphics but used KK and Kammys Kause in place of the GT and Vertigo. Painted it satin white with a pearl clear. It’s mostly original besides some bolts that wouldn’t clean up and the wheels and tires.
