Has anyone ever installed one. Amazon has a few (link), they're a) designed mostly for decks b) all pretty ugly c) open down a fairly steep angle (concerned about working headroom though obviously you can always mount them higher above garage door). My single car garage is literally full of bikes, so working on them, especially in the spring/fall when it's rainy here in Oregon sucks. I found this Youtube video. I'd be fine with a manually operated one. I have an EZ-Up but it's too large for the driveway and a pain to setup/teardown if I just want to work on a bike for an hour and I don't want any kind of permanent cover. Curious if there are better options.
