Biking is an excellent alternative to running if you have shin splints. I'm not sure if it will help them, I don't know alot about them, but it will be much easier on you because there is no impact.
riding bikes helps some, yes. But its not the best way. if you want stronger calves do calf raises. its really simple. riding a bike is not the only answer, nor is it the best way to achieve your goal
