WHEELS AND TIRES
• Check again to make sure the tube is well
seated and press the tire with your palm
over the rim bead. If this fails, you must use
tire levers. Make sure that the dull side is
facing the tube so as not to damage it.
• Press the valve into the interior of the tire
so that the tube is not pinched between
the tire and rim.
• Is the valve facing straight up? If it is not
remove one side of the tire and readjust
the tube. If you want to make sure that the
tube is not crushed under the edge, you
should halfway inflate the tire and roll it
back and forth around the circumference of
the wheel.
• Pump up the tire to the desired pressure.
The maximum pressure is indicated on the
sidewall of the tire.
• Check the t of the tire specically the wire
(or Kevlar) bead against the sidewall of the
rim. The important thing is that the whole
tire has a uniform distance from the rim.
MOUNTING THE WHEELS
Mounting the wheels follows the reverse
procedure to their removal.
Mounting the gear arm
• For a Birdy with Shimano gear hubs the
gear arm must be assembled before
mounting the rear wheel. The lock ring
must be turned clockwise. Note the posi-
tion of the colored dots and that gear is
shifted to gear 1.
TIP!
Depending on the Birdy type it is more
dicult to remove and mount the
rear wheel as compared to a standard
bicycle. We recommend you practice
this work before the rst ride. Then it
will be easier on the road.
