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 $25, you get a bicycle tune-up at Santa Fe Mountain Sports (a $50 value).

Santa Fe Mountain Sports’ specialty shop snatches sick bikes off the road and doctors them back to full health. Once dropped off, dizzy velocipedes are stabilized during a customized tune-up. The shop’s skilled bike gurus will adjust brakes and drive trains, check gears and shifting, tighten bolts, and clean bodies and wheels until your pedalmobile sparkles like brand-new asphalt, ready to tackle unexplored trails and sidewalks. Tune-up spa treatments are completed in up to three days, after which bikes exhibit smoother faces and buffed frames, and are less likely to buck off their riders during bouts of seasonal anxiety.
