Cool. I can see how it works well enough for my purposes from your post.

Where did you get the pulleys and what did they cost?

I have an old garage door opener and want to make a powered multi-bike lift. This is giving me some good ideas.

Nice. The use of the track is very clever.

I've seen similar hangers made to store small boats against garage ceilings so they don't take up floor space. The pulleys should be available at any hardware or home store.

its really cheap, the whole thing cost me around 20-30$ included everything.
u can find systems with pulleys for around 50-100$. but thing is the track , u can move the bicycle to
the corner of the room .
