Outside of the hand me down trike. My first bike was some 50-60's era Schwinn bike with 20" tires and coaster brakes but the frame was a traditional triangle. Made it into a Stingray and painted it metalflake green with a few coats of laq clear. Rode it everywhere. Loads of fun until it got stolen. One of a kind. Next bike was a 1968 Royce Union 3-speed which i still have and it has been my most reliable and durable bike.
