Ski Bike


This will show you one way to build yourself a Ski Bike (aka Snow Bike, Skibob, Skike, or Skicycle). It is a downhill only machine and if you like bikes a lot, then it will probably keep a stupid grin plastered on your face all the way down whatever crazy hills you choose to take it on. It is easier to ride than it looks and is quite stable at high speeds (not sure about the speeds you could achieve at a ski hill, but its worked great for average hills in Wisconsin).
There are many ways you could build one of these, this is just one way to get you started.
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 g…

step 2 Remove the chainwheel
You don't need or want a chainwheel on a ski bike. I don't know if you've ever been damaged by a chainrwheel in a bike crash, but its not fun. This bike has a one piece cra…

step 3 Prepare skis
Pay a visit to your local thrift store and get yourself a cheap pair of old skis. I paid $2 for this pair of Heads. Decide how long you'd like your skis to be. I've found …

step 4Attach axles to bike
For my design, I decided to use 3/8-16 threaded rod for the axles due to cheapness and abundance of compatible hardware. Buy a ton of matching nuts and washers at Fleet Far…

step 5 Cut wood for ski mounts
Get yourself some wood that will fit between the dropouts of your bike (especially the front, which is generally narrower spacing) and be able to rotate freely without catc…

step 6 Attach blocks to ski
Now its time to screw the blocks onto the skis. First, you'll want to decide how far back you want your blocks. With 24" skis, I decided to put the blocks 6.25" from the ba…

step 7 Attach axle clamp block
Now you've got to attach the top block that will clamp the axle in place. This design is a little bit strange, but I decided to go with it because it allows fore/aft adjust…

step 8 Finished ski bike!
You're done! Go test ride it if you've got any snow. Make adjustments to the seat and handlebars until it feels right.To all who may be skeptical of the ski attachment syst…

step 9 Extra Mods
I finally got around to doing some other stuff to this bike. I was able to find and fit a 26" fork to this bike in order to reduce its tendency to double up and launch you…
