Much like robots, children, and robotic children, bikes need to be regularly recalibrated to keep them from developing human emotions. Keep your bike performing at its functional, unfeeling best with today's Groupon: for $85, you get a professional bike fitting at Pedal Power Bike Shop (a $170 value).

Pedal Power Bike Shop’s friendly technicians incorporate techniques developed by the Serotta International Cycling Institute during professional bike fittings to customize cycles to each rider’s desires and capabilities. Tailored to two-wheelers of all brands, styles, and types, personalized two- to three-hour fittings begin with an interview covering the customer’s lifestyle and needs, such as any preexisting aches, daily routes, or dreams of jumping over the Adirondacks. Then, a physical assessment yields basic measurements and tests flexibility, priming patrons for a pedaling session atop an indoor trainer that allows the technician to determine the rider’s general position in real time. Drawing on the info they’ve gleaned, fitters will then make custom adjustments to client's bikes to help ensure a comfortable and efficient ride. Ideal for fostering one-of-a-kind comfort, bike fittings may also aid riders in avoiding strain and injury from repetitive use or from using the bike as a bed.
