Bicycles are simple transportation, but they, too, can need repair. Single- and three-speed bikes are relatively easy to repair, but those with more speed gears require more repair knowledge and finesse. It's a good thing that the Fix-It Club knows how to keep bikes in top condition.

How Does It Work?

A bicycle is a vehicle with two inline wheels, a steering handle, an uncomfortable seat, and pedals. The pedals are used to turn the chain assembly that turns the rear wheel for forward motion.

There is a wide variety of bicycles from single-speed bicycles with pedal-controlled coaster brakes to multispeed bikes equipped with a sophisticated system of derailleurs, freewheels, chain rings, and pressure brakes. The extra components allow the bike to run easily through a range of gear combinations at the touch of a precision index shifter--and help you stop the bike.

Caution!

When parking a bicycle, use the kickstand to keep it from falling over. If you must lay the bike down on its side, lay it on the left side so as not to damage the freewheel, chain rings, and derailleurs.

What Can Go Wrong?

The list is short: Lubricated parts dry out. Tires go flat. Brakes get out of adjustment. Chains wear out.

Fix-It Tip

Once you're done with a ride, make sure you clean dirt and debris off the tires, wipe moisture off components, and clean the chain of debris. If you wipe the chain, lightly lubricate it to replace the oil removed.
