Before wintertime hibernation, bicycles forage and fill their inner tubes with enough sustenance to feed training-wheeled cubs come spring, a noble act that often leads to serious exhaustion. Help spin the spokes of life with today's Groupon: for $30, you get a standard tune-up (a $60 value) at Scotts Valley Cycle Sport, located on Mount Hermon Road in Scotts Valley.

The bike mechanics at Scotts Valley Cycle Sport are experts at prepping velocipedes for a season of safe and smooth riding. During the standard tune-up, technicians will adjust cycles' brakes, derailleur gears, and bearings to make sure riders can fluidly stop on a dime, put the dime in their pocket, and pedal away. After sufficiently lubing cables and chains, the friendly staff will align wheels to steadfastly point toward the North Star. At the end of the tune-up, Cycle Sport's mechanics will wipe down the bicycle and suggest replacements or alternative musical uses for worn-out parts.
