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 (< 0 kg): The trailer could reduce the traction of the bicycle 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 permitted range of 0 – 8 kg cause unwanted handling performance.
Checking the tow bar load
Use bathroom scales, for example, to measure the tow bar load:
»
Load the
Sportrex
in the usual way and fasten the children in.
»
Do not connect the trailer to the bicycle yet.
»
Place the bathroom scales next to the tow bar.
»
Get onto the bathroom scales and note the weight displayed.
»
Lift tow bar head up to the height of the coupler (approx. 35cm).
»
The tow bar load is the difference between the measured vaules:
–
The weight
must be equal to or higher
than the measured value without drawbar.
–
The weight
may be a maximum of 8 kg more
than the measured value without the tow bar.
Changing the tow bar load
Adjust the tow bar load by moving or reducing your baggage:
»
Tow bar load over 8 kg: Move luggage to the back.
»
Tow bar load less than 0 kg: Move luggage to the front.
Total weight too heavy
»
Reduce the baggage weight in the pouch for small items.
»
Reduce the baggage weight in the storage space.
»
Make sure that the loaded
Sportrex1
weighs less than 50 kg.
»
Make sure that the loaded
Sportrex2
weighs less than 60 kg.
