25.1 Measuring and adjusting the chain
tension
Information
If the bicycle chain is too tight, pedalling will require
greater eort. The constant tension on the chain links
will also increase wear on the chain. You can tell if
your bicycle chain is not tensioned enough because
the chain will visibly sag, or jump o when riding over
uneven ground. If this is the case, the chain should be
tightened as soon as possible.
25.1.1 Derailleur: measuring the chain
tension
On derailleurs, a spring in the
rear derailleur keeps the chain
at the correct tension. If the
chain still sags, this can be due
to a dirty chain tensioner. If
the chain is still too loose after
you have cleaned the chain
tensioner, the spring in the rear
derailleur may be faulty. If this
is the case, the rear derailleur
must be replaced. Please contact your cycle dealer.
25.1.2 Hub gear: measuring the chain tension
1. Pedelec: Remove the battery.
2. Press the chain up or down at its tautest point. The
correct tension is reached when the chain sags.
3. Check the chain at four or ve points over a complete
revolution of the chain.

25.1.3 Hub gear: adjusting the chain tension
1. Pedelec/S-Pedelec: Remove the battery.
2. Undo the rear wheel nuts.
3. Remove the brake anchor as required.
4. Pull the rear wheel back in the drop-outs until the
chain just has the permissible amount of play.
5. Carefully tighten all bolts in a clockwise direction to a
torque setting of 35 - 40 Nm. Make sure the wheel is
retted straight.
25.2 Checking for chain wear
1. Pedelec/S-Pedelec: Remove the battery.
2. Check chain wear using a chain wear gauge.
3. Have the chain replaced by your dealer if it is worn.
25.3 Cleaning and care
Notice
Damage to the electronics due to water ingress.
▪ Do not spray the bicycle or its components, either
with a water hose or with a high-pressure cleaning
device. Although the components are sealed,
damage to the cycle may still result. Clean the bike
with a soft damp cloth.
Remove the battery before cleaning the chain on an
S-Pedelec or Pedelec. Then, roughly brush the bicycle
chain and chain tensioner with a soft brush. You can then
remove the old chain oil with a dry cloth. Now you can oil
the chain. We recommend high-quality chain oils, used
sparingly. Apply the oil to the lower chain from above,
turning the crank as you do so. Then, turn the crank further
and shift through all gears in the derailleurs.
26. Belt
Warnings
Pedelec/S-Pedelec: serious bruising due to accidental
actuation of the On button.
▪ Remove the battery before taking measurements,
setting or cleaning your Pedelec/S-Pedelec.
Serious injury caused by worn or damaged belts.
▪ Check the belt for signs of wear before every trip
26.3 Checking the belt for wear Page EN-51. A worn or
damaged drive belt can break.
Notice
Destroyed belt due to incorrect use.
▪ Do not kink, twist, bend backwards, turn over, knot
or bind together the belt.
26.1 Measuring the belt tension
There are various ways to measure the tension of the drive
belt. One of these is the Carbon Drive app, which measures
the tension based on the natural frequency (Hz) of the belt
length. You can download the app from gatescarbondrive.
