If keeping a bike outside for a while, any car cover does well. This is an up-cycle cover from a C5 Vette, when I got a new tech cover for the car. Works great and if you check the Thrift stores or Free Stuff on Craigslist, car covers can often be found for a song. Bungee's keep it from blowing away, and it fit's so baggy, it's impossible to tell what's underneath. Good Luck.
