@feisty76 I have a nice 2 wheel bike but cannot ride it because of my knee issues. And my idea of a three wheel bike, right now, is a CanAm Spyder motorcycle. I almost have my husband convince to go halfsies with me on a used one! When walking I use walking poles in each hand, which help my balance and gives me a nice stride. Beyond that, they can be used very effectively against any dog who would attempt to upset me, and to maintain a socially acceptable distance. Not that at my walk time at sunrise there is anyone else out...
