Yes, I use bicycle wheels. There is a gentleman who puts wrecked bikes together for under privileged kids and he often cannot use a wheel because it is bent or rusted and I love rusted metal in the garden. These are really easy to put together it is only the bottles you have to work with.
Yes Bud Platinum comes in blue glass bottles. Here is a photo of my bottle rainbow using blue beer bottles and green spumante bottles.
Another thing you can do with bike wheels if you have some colored glass......
I love my bottle trees. smiles
