Worthlees, thank you for the comment. Yes, I think there will be enough room for foul weather riding. Will be putting mudguards on the bike before the snow flies, that will keep most of the crud contained.

Had to make a small change in the design. The inner tube wraps on the chainstays didn't work out so well. Allowed too much movement of the framework. So I made a couple of plates and clamped them on with 4 vinyl covers clamps each. Is now solid!

There is one caveat with this system though, in order to remove the rear wheel, I have to pull the skewer completely out.

Next project for the bike is figuring out how to make a front carrier.
