To repair a punctured bike tire, you will need:
• Tire levers (plastic)
• Spanner or wrench (for wheels without quick re-
lease levers)
• Air pump
• Spare tube
Disk brakes:
• The wheel can be removed without any further
preparation.
• Please note: when fitting the wheel, the disk
must be slotted between the brake linings of
the brake calliper and ultimately be centred
without contact
1. Removing the wheel
• If your pedelec has quick release levers or ax-
les, open them (see page 17)
• If your pedelec has hex nuts, loosen these with
a suitable spanner anti-clockwise.
You can then remove the front wheel according
to the steps listed above.

The following applies for rear wheels:
• If your pedelec uses a derailleur gear system,
change gear to the smallest sprocket. In this
position, the rear derailleur poses the least hin-
drance in removing the wheel.
• If your pedelec has quick release levers or ax-
les, open them (see page 17).
• If your pedelec has hex nuts, loosen them in
anti-clockwise direction with a ring spanner in
the correct size.
• Pull the derailleur backwards a little.
• Lift the pedelec slightly.
• Tap the wheel from above with the palm of the
hand.
• Take the wheel out of the frame.
Types of pedelec inner tube valves:
2. Disassemble tire and inner tube
• Remove the valve cap, the locking nut and
possibly the union nut from the valve. For Dun-
techdocs
®
lop valves, remove the valve core.
• Let the remainder of the air out of the tube.
• Insert the tire lever opposite the valve on the
inside of the tire.
• Insert the second tire lever approx. 10 cm from
the first, between the rim and tire.
• Lift the tire wall over the edge of the rim.
• Lever the tire as often over the rim as is nec-
essary for loosening the tire all around the rim.
• Take the tube out of the tire.
3. Fit the tire and new inner tube
Avoid foreign objects getting inside
the tire. Make sure that the tube is
wrinkle-free and does not get
pinched anywhere. Ensure that the rim tape
covers all spoke nipples and does not show
any sign of damage.
• Push the valve through the valve hole in the
rim and place the hose inside the tire.
• Use the ball of the hand to press the other side
of the tire completely over the edge of the rim.
• Verify that the tube is properly seated.
• In the case of Dunlop valves: Replace the
valve core in its seat and tighten the union nut.
• Pump a little air into the tube.
• Check that the tire is properly in place and
turns straight using the control ring on the side
of the tire. Correct the tire's position by hand if
it does not turn straight.
• Pump air into the tire up to the recommended
pressure.
