• one or two control cables
• one front sprocket called a chainring
• a drive chain
a. Shifting internal gear hub gears
Shifting with an internal gear hub drivetrain is simply a matter of moving the
shifter to the indicated position for the desired gear ratio. After you have moved
the shifter to the gear position of your choice, ease the pressure on the pedals
for an instant to allow the hub to complete the shift.
b. Which gear should I be in?
The numerically lowest gear (1) is for the steepest hills. The numerically
largest gear is for the greatest speed.
Shifting from an easier, "slower" gear (like 1) to a harder, "faster" gear (like 2 or
3) is called an upshift. Shifting from a harder, "faster" gear to an easier, "slower"
gear is called a downshift. It is not necessary to shift gears in sequence. Instead,
find the "starting gear" for the conditions — a gear which is hard enough for quick
acceleration but easy enough to let you start from a stop without wobbling — and
experiment with upshifting and downshifting to get a feel for the different gears.
At first, practice shifting where there are no obstacles, hazards or other traffic,
until you've built up your confidence. Learn to anticipate the need to shift, and
shift to a lower gear before the hill gets too steep. If you have difficulties with
shifting, the problem could be mechanical adjustment. See your dealer for help.
c. What if it won't shift gears?
If moving the shift control one click repeatedly fails to result in a smooth
shift to the next gear chances are that the mechanism is out of adjustment.
Take the bike to your dealer to have it adjusted.
If your bicycle has a single speed drivetrain, the chain requires tension to
make sure the chain doesn't come off the sprocket or chainring. Chain tension
requires a fine-tuned adjustment. We recommend that chain tension be
adjusted by your dealer.
1. Toe Overlap is when your toe can touch the front wheel when you turn
the handlebars to steer while a pedal is in the forwardmost position. This is
common on small-framed bicycles, and is avoided by keeping the inside pedal
up and the outside pedal down when making sharp turns. On any bicycle, this
technique will also prevent the inside pedal from striking the ground in a turn.
WARNING: BMX pedals are designed to provide greater grip
capability of the pedal tread surface than that provided by an
ordinary pedal. This can result in the pedal tread surface being
very rough and containing sharp edges. To avoid injury, Riders
should therefore not ride barefooted and should ride wearing a
pair of shoes with thick soles to ensure adequate safety protection.
