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 $100, you get a four-hour bike-repair workshop at Gracie’s Wrench (a $200 value). This Groupon is valid on dates workshops will be held: January 14, 15, 21, and 22, and February 4, 5, 11, and 12.
At Gracie’s Wrench, a certified instructor with 11 years of experience teaches groups of up to six the basics of bike diagnostics and maintenance. During a hands-on four-hour session, pedaling pupils practice on their own two-wheelers with provided tools, learning techniques and tricks for changing flats, basic maintenance, and teaching bikes to come when called. The teacher will also introduce the fundamentals of break and shifting adjustments, replacing pads, and setting up a maintenance schedule. Individual attention, handouts, and a review at the end of the workshop help students turn bicycles into well-oiled, city-cruising machines that will never burst into flames for no reason.
