Here's the ultimate DIY Ski Bike!!! I wanted it to function well, be super strong, easy to fabricate, not too heavy, and very cheap to make.
Here's what you'll need:
- an old BMX Bike (MTB's work too)
- 2x4 stud (x1)
- 8" Hinges (x2)
- 2" Lag Bolts (x12)
- 2" Drywall Screws (x12)
- 3/8" BMX wheel axles (x3) (keep all nuts)
- Flatland BMX Pegs (x2)
- a Pair of old Skis
- Spray paint
Step 1: Prepare bike
Remove the wheels, cranks and chain. Remove the axles from the front and rear wheel. Keep all your nuts. Keep the bottom bracket cups installed in the frame as a super strong seat for your pegs.
Step 2: Flatland Pegs
Use a set of large flatland style alloy pegs and a extra 3/8" BMX axle to create the standing platform.
Step 3: Install Pegs
The pegs seat perfectly into bottom bracket cups. This setup virtually bomb-proof.
Step 4: Setup the Hinges
Remove the hinge pin from the hinges by drilling out the spots where the pin is punched. Keep the plastic spacers in place (if any). The pins can vary slightly in diameter from brand to brand. I got mine at lowes and the bmx axles were a snug fit but required no modification. You may need to drill or ream or pry them out slightly to fit 3/8". Use the nuts and washers from the donor wheels to fill in the gaps. You don't want to pinch or spread your bike too much in order to make a snug fit. I backed off the inner most nuts a 1/4 turn away from the edge of the hinge so it swings freely on the axle.
