Dealing with a flat tyre
If there are problems removing the cable casing
from the counterholder of the shifter unit, insert
a 2 mm allen key or a #14 spoke into the ratchet.
By turning anti-clockwise, the gear cable is re-
laxed. First remove the cable fastening screw and
then the cable casing from the counterholder.
Step 4 : Loosen and remove the screw from
the brake arm fastener on the left chain stay
of your FLYER.
Step 5 : Unscrew the axle nuts of the rear wheel
with a suitable spanner (15 mm) anti-clockwise.
Step 6 : After removing the safety washers
from the hub axle, you can remove the rear
wheel from the rear fork of your pedelec.
20.3 Removing the tyre and inner tube
• Remove the valve cap and fastening nut
as well as possibly the cap nut from the
valve. Remove the valve stem from Dunlop
or Woods valves and keep this in as clean a
place as possible until it is reattached.
• Allow the remaining air to escape from the
inner tube.
In the case of a Presta valve (French valve), you
have to open this by turning and then pushing.
In the case of a Schrader valve, you can
help the remaining air to escape by pressing a
pointed object against the valve stem.
• Begin the process on the side opposite to
the valve on the inside edge of the wheel
with a suitable tyre lever.
• Now you can remove the inner tube from
the tyre.
20.4 Patching an inner tube
• Pump the inner tube back up in order to be
able to identify where the inner tube is dam-
aged. You may possibly have to remount the
valve stem (Dunlop or Woods valves).
• Ideally, you should be able to quickly iden-
tify the damaged spot by holding the inner
tube under water. The area in question can
be identified by the air bubbles escaping.
• If you are on a ride, you can pump the in-
ner tube up very strongly. The high pressure
will mean that lots of air should be heard or
felt escaping from the problem area if you
hold the inner tube close to your face.
• In order to patch the tube, it has to be dry in
the damaged area.
• Now carefully roughen the damaged area
with sandpaper slightly on the inner tube.
• Apply the rubber solution as thinly and
evenly as possible around the leaky area.
• Allow the rubber solution to dry for several
minutes.
• Then press the rubber patch on the dam-
aged area as firmly as possible and allow
this to dry for a few more minutes.

Always work on the other side of
the bike to the gearside on the
rear wheel. This helps avoid any
possible injuries if you slip.
• To start with, lift the tyre wall over the edge
of the rim.
• Insert the second tyre lever approx. 10 cm
from the first one and lift another section of
tyre from the rim well.
• Repeat this process until the tyre has
been completely removed from the rim
on one side.
