I recently built a vertical bike rack from scraps of 2x4s leftover from another project. I built this rack so that the rear wheel from one of our bikes could rest on the floor. I found that I would need this bike to be hung at 63.5" using these hooks
, but the wheelbase on this bike is larger than the wheelbase on my other bikes. You can adjust the length of the height (77" for my project) as needed.
The spacing of each bike will be 12", and the top level is 12" higher than the bottom level. If you don't want to alternate the levels to hang each bike, then you will need to accommodate for about 18" of spacing between each bike.
Lengths to cut 2x4s:
2 - 77"
4 - 36"
4 - 28.5"
5 - 15"
2 - 18"
2 - 20"
Screws: 2.5" wood screws
Bike Hooks: Any bike hook system will do, but I picked up these
from Home Depot.
Edit: Read this instructable
. It is important for the discussion of spacing as well as to see how they did the hooks. One of my bikes rubbed the coating off one hook, so I repaired it with handlebar wrapping and electrical tape.
If you only need to hang one bike, here is my single bike design
