Very good exercising and training, it is never too late to ride bicycles. Cycling is good for your knees and ankles as compared to jogging. If distance is short like less than 12 miles (20KM), I rode my heavy MTB (35lbs full suspension) to train my physical, and rode road bike for longer distance. Actually, you don't put much of load (weight) on your spine when riding road bikes. Even you bent your back, most of the weight falls in your forarms and butt.
I am not that younger from you, so let's keep enjoying the riding.
