The lack of cheap, simple and good looking bike rack solutions was annoying me so this is my super cheap, very simple and quite good looking solution:
I mounted it to a piece of plywood just to test it before I take it to it’s permanent home and it’s surprisingly sturdy and the cubby hole is a great place for your D-lock and tools etc as well as the hooks for helmets/jackets.
Screwdriver and/or drill
1. Draw cutting lines, spaced far enough apart for the down/top tube of your bike to fit in.
2. Cut along the lines, I just used a hacksaw. cut along the top. As well as an inch or so down on either side (picture in part 3 explains this better)
3. Cut the strip out that you have just created (strong scissors work well), leaving a flap on either side which gets folded down/cut out if you want
4. Sand the edges
5. Mount to the wall (make sure you use the appropriate method for your wall material)
And you’re done!
(I hold no responsibility for damage that happens to your wall/bike. This method works for me but your walls may be different or your bike heavier but enjoy and any suggestions are welcome)
