I just built a bike store as part of a new shed and used these folding hooks, and can confirm they're excellent. Being able to fold them means I can fit the bikes into a narrow space and remove them easily. definitely recommended. apologies for the crap photo tho.
Anyone tried anything like this? Hanging wheel hooks that allow the bike to pivot. Might be a good way to pack more bike into a smaller shed space.
