Pocket
bikes, super pocket bikes, also
known as mini motos, are miniature sized motorcycles averaging
around 47 inches long and 18 inches tall. Pocket bikes,
although small enough to carry under one's arm, are capable
of impressive speeds. They are usually built with gas-powered
engines. The smaller industrial-motored models
used by Junior class racers are capable of speeds of over
35 mph, the average 4.2 hp and 6.2 hp racing models achieve
about 40-45 mph, and open class machines reach speeds
over 50 mph. Pocket bikes can be built
with many of the features common to regular bikes, such
as disc brakes in the front and rear, racing tires, fairings,
lightweight aluminum alloy cast perimeter frames and swing
arms.
