Bicycle Built for Two by Jeff Adams

While on a three-day charity bike ride from Boston to New York City, Jason Karn makes an unexpected stop to help a fellow rider having trouble with a flat tire. Ben Stewart is new to long-distance rides, and Jason takes him under his wing. The mutual attraction is obvious even before they make it to New York City, but there’s a minor roadblock: Ben lives in Chicago. Flying back and forth seems like the only option until Jason comes up with an idea that will bring them together permanently—if they can work out the details.
