I'm not responsible if anyone gets hurt during the construction or use of this product. I design and construct this product in a manner that I believe is safe, but as in everything accidents do happen, so follow this Instructable at your own risk and please use all applicable safety equipment during the use and construction of this product such as a helmet when wearing it.
Now that we got that out of the way, time to begin the fun!
In this Instructable we're going to learn how to build a bike that is ride-able in the snow, aka a snow bike, out of simple materials that are cheap and easy to work with. A good thing about this project is that the bike can be easily converted back afterwards.
Step 1: Materials List
• Ski or pair of skis preferably small, otherwise you may have to cut them down (I only had water skis, so i used those, but snow would probably work best)
• Zip-ties (at least 44, I bought two packs of 30 zip ties at the local dollar store for a dollar each.)
• A bike that isn't super expensive. (I used a $20 yard sale bike just in case something goes wrong you are not out much. Don't use your $2,000 Specialized or KHS for this project just to be safe.)
• Tape Measure
• Cutters that can cut zip-ties
• Some type of writing utensil that can write on wood. Permanent markers and grease pencils work best.
• Optional: For better precision of holes use a drill press
Step 2: Unscrew the Bindings
If you are using children's skis and they are connected, also remove anything connecting the two skis together.
Step 3: Measure and Mark
Once you know the width of your tire, measure out how far the bindings must move in in order to have the binding edge against the tire. To do this, you can measure the middle of your ski and then offset each binding just a tiny bit over (1/32" or 1/64" should do) half of the width of the tire on each side of the center of the ski. For example if we have a 1.5" wide tire we would measure measure .8 from the right and left of the center and that's where each binding would go.
Once you've found the correct distance, now just measure over the holes in the same manner and mark them.
Step 4: Drill Holes
Step 5: Screw the Bindings Back In
Step 6: Put Wheel Into Bindings and Deflate
Now, move the bike so that the tire is in between the bindings on top of the zip-ties.
Once you have it centered well, deflate the tire. Notice how the rubber fills and gaps between the bindings and the wheel and forms a nice tight fit.
