Like the Tin Man, bikes need to be properly lubed, or they’ll break down on long journeys and be carried away by flying monkeys. Avoid cycle-stealing simians with today's Groupon: for $37, you get a standard tune-up at Cycleton (a $75 value).

At Cycleton, a Specialized Elite store and service shop, the friendly staff restores bicycles with professional-level maintenance skills. Boasting more than 60 years of combined experience, the staff of wheel whisperers begins each tune-up by scrubbing the body to remove muck and rust, followed by adjustments to the derailleur gears, brakes, bearings, and warp thrusters. Maintenance experts summon their velocipedal clairvoyance to correctly align the derailleur hanger, true the wheels, and tighten all the hardware to ensure nothing rattles or uncontrollably sobs. With a freshly lubed chain and well-pumped tires, cycles will be prepared for any epic journeys, from the Tour de France to the Oregon Trail. Cyclists can drop off bikes on the fly or make appointments for faster returns.
