Utilisation
f
Adjust the left and right seat belts to the same position
and length.
f
Loosen the Velcro fastener for the belt pad fixation as
described in section
„Adjusting the position of the seat
belts“ on page 26
.
f
Position the left or right pair of seat belt pads in the
middle position using the inner slots of the left and right
positions.
f
Use the inner straps of the right and left seat belts for the
middle position. To do this, turn the tabs over.
f
Put the harness catch, including the pad, onto the centre
harness on the front of the seat. Use the harness catch
of the left or right seat to do this.
f
Use the left and right grey belts under the seat to tighten
the seat belts of the seat system.
f
Repeat this procedure in reverse order whenever you
require the safety harnesses for carrying two children.
Checking the weight distribution and tow bar load
An optimum weight distribution is important for safe handling: The load’s centre of gravity should
always lie in the centre of the wheel axle. The tow bar load with which the tow bar lies on the coupler
must be neither too great nor too low in Trailer mode:
Tow bar load too great (> 8 kg): Too much load on the coupler.
Tow bar load too low (< 3 kg): The trailer could reduce the traction of the rear wheel through lifting
and thereby cause critical situations in curves.
Center of gravity too far out: One-sided loading favors overturning in curves.
Danger!
Distribute the load evenly across the width of the
Sportrex
. If you are carrying only 1 child,
he/she must sit in the middle, see
„Mid sitting position (Sportrex2)“ on page 26
.
Check the tow bar load before every journey with a trailer. Tow bar loads outside the permit-
ted range of 3 – 8 kg cause critical handling performance.
Checking the tow bar load
Use bathroom scales, for example, to measure the tow bar load:
f
Load the
Sportrex
in the usual way and fasten the children in.
f
Do not connect the trailer to the bicycle yet.
f
Place the bathroom scales next to the tow bar.
f
Get onto the bathroom scales and note the weight displayed.
f
Lift the tow’s bar coupler pocket to the coupler height (ca. 35 cm).
