Pedals - Tern Quick Haul D7i Bedienungsanleitung

combination shift/brake controls and push-buttons. Ask your Dealer to explain the type
of shifting controls that are on your bike, and to show you how they work.
For derailleur systems, Tern Pedelecs primarily only have a rear derailleur. Consult your
bike's QuickStart Guide to see if your bike model uses a front derailleur.
In a derailleur system, a downshift is a shift to a "lower" or "slower" gear, one that is easier to
pedal. An upshift is a shift to a "higher" or "faster", harder to pedal gear. Whether upshifting or
downshifting, the bicycle derailleur system design requires that the drive chain be moving forward
and be under at least some tension. A derailleur will shift only if you are pedaling forward.
WARNING: Never move the shifter while pedaling backward, nor pedal backwards
immediately after having moved the shifter. This could jam the chain and cause
serious damage to the bicycle, and cause you to lose control and fall.
Shifting the Rear Derailleur
The rear derailleur is controlled by the right shifter. Moving the chain from a smaller sprocket
to a larger sprocket results in a downshift. Moving the chain from a larger sprocket to a smaller
sprocket results in an upshift. Pedaling in the higher gears requires greater pedaling effort,
but takes you a greater distance with each revolution of the pedal cranks. Lower gears require
less pedaling effort, but takes you a shorter distance with each pedal crank revolution.
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 adjustment and the chain could jam, causing you to lose control and fall.
6.D.2. Internal Gears
If your bicycle has an internal gear hub drivetrain, the gear changing mechanism will consist of:
• A finite set of speeds (anywhere from three to an infinitely variable internal gear hub)
• One, or sometimes two shifters
• One or two control cables
• One front sprocket called a chainring
• A drive chain
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.
6.D.3. Choosing a Gear
Find the "starting gear" which is right for your level of ability — 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 gear combinations.
WARNING: 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, such as shifting to a lower gear before a hill gets too steep.
DEALER: If you have difficulties with shifting or cannot shift, the problem
could be mechanical adjustment. See your Dealer for help.
6.E. Pedals
Toe overlap is when your toe can touch the front wheel when you turn the handlebars to steer while
a pedal is in the forward-most 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.
NOTE: Changing tire size or pedal crank arm length affects toe overlap.
WARNING: Toe overlap could cause you to lose control and fall. Ask your Dealer to
help you determine if the combination of frame size, crank arm length, pedal design and
shoes you will use results in pedal overlap. Whether you have overlap or not, you must
