6.2.1.1 Adjusting the Rear Wheel Axle

The axle assembly is continuously adjustable horizontally on the seat tubes.
1) Remove the wheels.
2) Pull the side panels out of the guides on the side panel mountings.
3) Loosen the connection between the seat plate or seat upholstery and the seat tube clamps:
→ With a seat plate: Loosen the Allen head screws between the seat plate and seat tube clamps (see fig. 3,
item 1).

(see fig. 4, item 1). Remove the seat upholstery.
4) Loosen the Allen head screws respectively between the seat tube clamps and seat tubes (see fig. 3, item 2).
5) Move the axle assembly to the desired position (see fig. 5).
6) Ensure that the depth setting is the same. For fine-tuning, measure the distance respectively between the
centre of the axle tube and the centre of the lower screw on the back bracket (see fig. 6).
7) Tighten the Allen head screws between the seat tube clamps and seat tubes to 15 Nm (see fig. 3, item 2).
8) Reconnect the seat plate or seat upholstery and the seat tube clamps:
→ With a seat plate: Tighten the Allen head screws between the seat plate and seat tube clamps to 8 Nm
(see fig. 3, item 1).
→ With seat upholstery: At the height of the adjusted seat tube clamps, punch the seat upholstery with a
6 mm hole punch and drill 6 mm holes in the upholstery tube. Tighten the Allen head screws between the
seat upholstery and seat tube clamps to 8 Nm (see fig. 4, item 1).
9) Slide the side panels back into the side panel mountings. Adjust the side panels if necessary (see Page 20).
