I recently designed and built an inexpensive free standing bike rack suitable for shop use. It holds 19 bikes vertically from hooks, with alternating bikes pointing up and down, and with handlebars facing out. My goals were to:
floor/wall hooks are not allowed
Now I would like to share this design. Here is a link to a six page PDF file showing how to build this rack, how much the parts cost if purchased new, and how to reduce the cost.
