Elliptigo long stride upright bicycle. The closest thing to jogging without pounding the pavement. Easy on your joints and great for cross-training. Originally bought for 2995 selling now for $500. This is the model 8C it has 8 speeds. I used it for many years but has been sitting idle due to an illness and balance issues.
