Biking Bison

An xtracycle is a really cool design for biking that extends the frame length of your bike, so that your cargo capacity greatly increases, while the mobility and agility of the bike remains pretty consistent. www.xtracycle.com I have been wanting one of these for quite some time, but the high price tag is pretty steep when I already have 5-6 bikes in the garage. After searching around some internet forums, I discovered a growing population of DIYers who are creating their own versions of this bike design. Here is my attempt at documenting my steps in creating my own.

this is a craigslist find. someone selling frame only, I intend to pull many of the necessary parts off of the full suspension bike

here is the first mockup on what the frame extension might look like

the rear dropouts on the full bike frame will line up with the bottom bracket, (or where the pedals connected) on the full suspension bike

the full frame is on the bike stand, and the rear suspension triangle is being held in place with some large spring clamps

here is a rear view of the mockup. a rear wheel is in the front fork, just to give an idea what the profile will be

this is a topside view of where the connections will happen between the bikes. the frame is a bit wider than the bottom bracket. I will need to add some time of washer or spacer to make up the difference
