I have a walker and three and a half years ago I could not even move about my home without it. Quite an experience. I will always have it folded in the corner of my living room right next to my recumbant eliptical to remind me of the alternative to not keeping my legs flexible. I have two road bikes for fair weather riding and see no need for e assist at all for my level of riding but I am all for someone spending their own cash as they see fit regardless of age or fitness level.... As long as they wave and don't yell at me out on the MUP :-)
