I commute to work on my bike so I tend to work on it more than your casual weekend biker. The repair videos on Youtube where people are using fancy freestanding racks to work on their bikes made me envious so I made my own, simpler version.
All it is is a wall bike hanger mounted on a 2×4. The top of the 2×4 clamps to a rafter in my garage.
The extension board attached on top lets me work in the basement during cold months; the rafters there are much lower.
