WARNING: Never shift a derailleur onto the largest or the smallest sprocket
if the derailleur is not shifting smoothly. The derailleur may be out of adjust-
ment and the chain could jam, causing you to lose control and fall.
2. How an internal gear hub drivetrain works
If your bicycle has an internal gear hub drivetrain, the gear
changing mechanism will consist of:
• a 3, 5, 7 or possibly 12 speed internal gear hub
• one, or sometimes two shifters
• 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.
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.

Which gear should I be in?
The numerically lowest gear (1) is for the steepest hills. The
numerically largest gear (3, 5, 7 or 12, depending on the number
of speeds of your hub) 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. If you have difficulties with shifting, the problem could
be mechanical adjustment. See your dealer for help.

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 turning.
WARNING: Toe Overlap could cause you to lose control and fall. If you
have toe overlap, exercise extra care when turning.
2.
Some higher performance bicycles come equipped with
pedals that have sharp and potentially dangerous surfaces. These
surfaces are designed to add safety by increasing adhesion
between the rider’s shoe and the pedal. If your bicycle has this
type of high-performance pedal, you must take extra care to
avoid serious injury from the pedals’ sharp surfaces. Based on your
riding style or skill level, you may prefer a less aggressive pedal
design. Your dealer can show you a number of options and make
suitable recommendations.

positioned and engaged with the pedals. The toeclip positions the
