Dale, it will be five years in November since I quit after smoking for over 35 years myself. I know what you mean about missing the smoke after the ride. The lung capacity will return over time but believe me you will soon be biking longer and further than you did in the past. Think of all the goodies for the bike that you can buy with the money you are saving. Quitting was probably one of the best things that you could do for yourself. I found the following site very helpful during the first six month of quitting.
