Ok, so a couple of things that have come to me. You have a right to peace and quite and he has a right to work on and ride his bikes. Perhaps you could bake him up a nice treat (cookies, cake, brownies, pie, etc.) and visit with him to discuss a happy medium that you both can live with, like a time frame where you can expect peace and quite and a time frame where he can make noise. If you have a favorite tv program, etc.

Most people are not complete jerks and are willing to be reasonable.
