Mounting the axle coupling (quick release)
The coupling is always mounted on the left-hand side of the tractor wheel, as seen in the direction
of travel. It consists of two parts: the drawbar head, which is attached to the drawbar, and the axle
coupling, which is attached to the axle of the rear wheel hub of the towing bicycle. Before you
mount the axle coupling, you must determine whether your bicycle is suitable for towing a trailer.
Check the owner's manual of the bicycle, ask the manufacturer or ask a bicycle dealer.

1. Open the quick-release lever on the rear wheel of the traction bike or loosen the hexagon
socket screw (5 mm), depending on the version of the quick-release axle. Often the direction of
movement of the clamping lever is marked "OPEN".

5. Align the rear wheel and close the quick-release lever or tighten the hexagon socket screw,
depending on the quick-release axle version. The direction of movement of the clamping lever is
often marked "CLOSE". The force you apply must increase from about half way. In the last area
the lever must be parallel to the frame and must not stick out.

release around its own axis. If the quick-release can be twisted, the clamping force is not

If the clamping lever cannot be closed completely, open the clamping lever and screw the axle nut
half a turn anticlockwise. Repeat steps 5 and 6. Note that the axle nut must be screwed onto the
the rear wheel, which can lead to accidents with life-threatening injuries. The quick-release
axle is then too short and must be replaced. This is available as an accessory. Contact a
specialist workshop.
