Dirt Jump
Bikes designed for jumping, hucking, high
speeds, or aggressive riding on rougher surfaces, or landing on
at surfaces. However, this type of riding is extremely hazardous
and puts unpredictable forces on a bicycle which may overload the
frame, fork, or parts. If you choose to ride in Condition 5 terrain,
you should take appropriate safety precautions such as more
frequent bike inspections and replacement of equipment. You
should also wear comprehensive safety equipment such as a full-
face helmet, pads, and body armor.
For man-made dirt jumps, ramps, skate parks other predictable
obstacles and terrain where riders need and use skill and bike control, rather than
suspension. Dirt Jumping bikes are used much like heavy duty BMX bikes.
A Dirt Jumping bike does not give you skills to jump. Read Section 2. F, p. 10.
For terrain, drop offs or landings where large amounts of
suspension travel are needed to help absorb the shock of landing and help maintain
control.
Dirt Jumping bikes are lighter and more nimble than Freeride bikes,
but they have no rear suspension and the suspension travel in the front is much
shorter.
Kids
Bikes designed to be ridden by children. Parental supervision
is required at all times. Avoid areas involving automobiles, and
obstacles or hazards including inclines, curbs, stairs, sewer
grates or areas near drop-offs or pools.
