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.
I toyed with the idea of hooking the front forks of the 3 wheeler to the back forks of my 18 speed.
I stripped the trike of all unnecessary parts. I kept the handlebars to be used to attach the frame to my bike.
I skipped the idea of attaching the front forks of the 3 wheeler to the back of my bicycle, because when I turn on my bike, I lean. Hooking the bike up this way wouldn't work. After searching http://www.instructables.com, I came across someone who used casters as the solution I was looking for. So, off went the front forks.
I decided to re-use the handle bar to be the connecting rod between the two. It curved up and over my rear tire of my bicycle and lined up with the seat bar just perfectly.
