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 bike tune-up at B & J Bicycle Shop, Inc. (a $60 value) in Pompano Beach.

Also a bike retailer, the family-owned B & J Bicycle Shop has been tuning up two-wheelers for more than 25 years, transforming squeaky slowpokes into sleek street scurriers. Before servicing foot-powered fillies, an experienced cycle surgeon provides customers with a free estimate, discussing a bike's prognosis and what exactly its dreams mean. Whether a wheel is askew, the brakes are unreliable, or the spokes have been replaced with pick-up sticks, B & J will bring tired warhorses back to full functionality. Walk-ins are welcome, or call for an appointment for increased efficiency and the chance to communicate entirely in Morse code.
