I wanted to re-purpose my dad's old 3-wheeled Schwinn Meridian. My mom bought it for him and he wound up running into it with the car. The main reason she bought it for him in the first place. My woman and I have a couple of dogs and I wanted to find a way to bring them to the local park and ride the wonderful bike trails at the same time. Sure I could have bought a normal bicycle trailer, but then I wouldn't be sharing this Instructable!
Parts list and links at the end.
My dad, who had suffered a few strokes decided to drive the car into the bike, ruining two of the tires. Schwinn Meridians don't have normal bicycle tires. The hubs are bigger to allow a thick axle to go through, as one side turns with the axle when you pedal. I debated on how I could get the one rear tire repaired. More on the tires later.
