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.

Figured out a way tokeep the chain from rubbing finally. I used the old middle sprocket as a spacer to move things over about 1/8 inch.

Now the front sprocket is going to be about 1/8 inch to the left

now I am tightening the crank back into place

There is just bareley enough clearance between the chain and the bottom bracket

here is another angle. Its a close fit, but It is necessary

All the rubbing and wearing sounds I have been dealing with appear to be gone

Looking down the chain shows the perfect amount of space between the drive line and the frame
