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.

That is exellent work there. Cheapest and best setup I've seen. I have the standard wood blocks and now I'm going to swap them out for this. Thanks for sharing

So if I am more of a mountain biker, would you recommend that I build this using a mtn bike frame?

Yes, you can put these on any bike that uses 3/8" axles. You will need to add some spacers on the longer rear axle to accomodate for bikes that have a wider gap because they are sized for gears.

Couldn't you use skate trucks to connect the ski to the bike?
Skate trucks are cheap and break easily

Nice build! I like the hinge idea, slick. Now you just need some bungees to hold the tips up and some old tire tread wrapped around the pegs for more grip when they get covered in snow/ice.
by the way, not all heavy duty 8 inch hinges will work. I got some from home depot, and the 3/8 inch rod/axle wouldn't fit in the hinge, even after prying them open a bit. You may have to use the 12 inch hinges.
When you leave the bottom bracket cups in, do you leave the bearings in too?

no, just the cups

Great work! I'm working on a ski-bike of my own and have to say your hinge system is brilliant! I agree with the prior statement about adding some form of bungie system. Once you get that puppy airborne, you'll want to be sure the skis stay smooth side down!

you need to add elastic strips to keep the blades from rotating.
