Almost a year or so after building my first regular bike, I felt like making something a little bit different. One day an idea popped into my head for making a rear-wheel steering bicycle.

-The frame is from scrap pipe that was laying around.
-The wheels, tires, gears, cranks, headset, and chain were parted from an old (free) dumpster bike.

-The "steering shaft" is made from a piece of exhaust pipe tubing, welded to the bottom of a headset stem.

-The fork in the rear (and small tire) are from a thriftstore childrens bicycle. It was cut in half at the stem, where I added in square tubing for the steering cable to connect to.

-I used plastic pulleys, attached to the frame for the steering cable to run thru.

-The seat frame was made from steel tubing, and the seat itself was cut from 3/8" plywood. I was originally going to cover the wood with cushioning and fabric. But I never got around to it.




Some problems I have encountered:
If there is ever a day I decide to build another one of these contraptions, their are a couple of things I would do differently.

• The steering is way too sensitive. I need to enlarge the "steering shaft" in the front. And use a larger diameter wheel.
  

• The handle bars come in too close to the chest.
  

• In this current version, I eliminated the use of all the gears so that it is a single speed. This was mainly do to laziness. In the future I would keep it multi-speed.
  

• The pedal's are almost too far down, anybody shorter has trouble riding. If it could somehow be more universal, or an adjustable seat.
  

• When I first had the idea in mind I pictured being able to make very sharp turns, almost being able to stay in one place but in circles. Unfortunately, it did not work out this way. Their was probably something that could have be changed for this to be possible.
  

So if you ever plan on making something like this, keep these things in mind.
