A baby loves riding
My wife had a VW bus to ride to work; I had a Triumph Trophy 500. Our son rode strapped to me almost immediately. By the time he was 1 y/o, he insisted on riding in front of me. He had his first bike, a Yamaha RM50 before he was 5 y/o. He still rides and so do I.
If you care what your wife thinks about it, I cannot help you.
