Absolutely bike riding is a good form of exercise. You can ride a bicycle just about any time of the year in many locations and it is a relatively inexpensive activity. Cycling increases muscle strength and tone of the legs, cardiorespiratory function and burns calories.ny exercise that makes you move is a good exercise. Biking is one of my favorite exercises. My knees never hurt no matter how many miles I pedal. It is easier on the joints than running.
