"One of the joys of escaping Boston for the day is immersing yourself in some wide open space. Riverside Cycles, located in the center of town, has a selection of bikes and gear to suit everyone from novices to Tour de France trainees. If you're planning on working up a sweat with a daylong ride before coming back to Newburyport for dinner, reserve a lightweight carbon fiber road bike for $75 a day. Entry-level bikes—perfect for getting to and from the beach —start at $25 for a half day." - Todd Plummer
