TACHOMETER.

The Rider May Always Know What Time His Wheel Is Making;.

The tachometer is an instrument that Indicates minute variations in the speed of the bicycle. It is attached to the right-hand fork by a neat clasp, and can be swung in or out of position while riding. A small wjjeel is brought

into contact with the center of the tire; the wheel operates a hand on a dial, which shows the rate of hour. If, for Instance, it is 20 miles to his destination, and he pedals fast enough to hold the handle at the 20-mile mark, he will reach his destination in exactly one hour. It is both and aid to the rider to see.^a*various changes in speed, and is the best time-keeper going. It costs little, and weighs about 2% ounces.
