Ski Bike

Step 1 Get a bike

Find yourself a bike that you think would be suitable. I like to keep it small so that its easier to kick with your legs or do a running start and hop on. Smaller is also generally lighter and easier to carry up a hill. In addition, if you crash, you're closer to the ground. I got this BMX that someone was just throwing away. (Seriously, it just had a blown tire and slightly crooked front wheel, wtf?)

Strip all the unneeded parts off the bike. Namely, brakes, wheels and chain.

Look for a removable link in your chain to make your life easier. If there is none, then use a chain tool to push out a rivet. Or just chop it, whatever works.
