I am a firm believer in walking as an exercise for good health. Although I ride my bike nearly daily and love it as well as the exercise benefits I derive from it, biking is not weight-bearing exercise. Walking is. Your bones benefit from walking, so you are defending yourself from osteoporosis with every step.
We all need weight-bearing exercise as well as cardio.
