Assembly instructions for the Bicyclejack

Mounting the Bicyclejacks on a wall (replacement of the gas pressure cylinder see below)

The transport edge protection on the lower wheel recess can be removed. There is no need to assemble the Bicyclejack, it is completely assembled in the desired version.

Tip: One Bicyclejack can be mounted in a higher position (a higher assembly favours the power/lever travel, the bike can be lowered even easier), several Bicyclejacks can be mounted closer together or further apart. The following assembly instructions reflect recommended dimensions, based on standard bicycles with a handlebar width of 65 cm and a total length of 180 cm.

Step 1:

Measured from the ground, at a minimum of 130cm (preferably 150cm), the first fixing point for the top screw hole of the Bicyclejack wall spacer is marked (a higher installation makes parking easier). Distance from top screw hole to ceiling ≥ 60 cm.

Attention: if several Bicyclejacks are to be installed in a very small space, the Bicyclejack must be mounted alternately 20 cm apart in height, whereby the minimum dimensions from the floor to the top screw hole are 150 cm / 130 cm (distance top screw hole to ceiling ≥ 60 cm). A side distance from Bicyclejack to Bicyclejack should not be less than 35 cm. If you have more space on the wall, the Bicyclejacks can be mounted at the same height with a recommended minimum distance of 70 cm.

Step 2:

Depending on the substrate and choice of screws, drill the hole. A Bicyclejack is fixed with a total of 6 screws Ø 8 mm.

Step 3:

The Bicyclejack is first fixed to the corresponding wall by a screw in the top hole of the upper wall spacer (do not tighten firmly).

Step 4:

After the Bicyclejack has been aligned vertically with a spirit level, the positions for the other 5 attachment points are marked.

Step 5:

Depending on the base and choice of screws, drill the remaining holes.

Step 6:

The Bicyclejack is now fixed with another 5 screws Ø 8 mm. All 6 screws are finally tightened.

Done, the Bicyclejack is immediately ready for use:

Replacement of the gas spring:

Basically: A necessary replacement of the gas cylinder due to a bicycle change (bicycle is therefore heavier or lighter than the weight specification of the already mounted Bicyclejack) is possible without much effort. It doesn't matter which gas cylinder is to be used, all of our products are compatible with all Bicyclejacks.

The lever arm should be in the upper position. This is first secured against falling down. Then loosen the locking ring on the bolt of the "lever arm" / gas cylinder attachment. The gas cylinder is supported and the bolt can be removed. Now lift the lever arm a little bit upwards, the eye of the gas pressure damper slips out of the mounting. The gas pressure damper is now exposed on one side. Loosen the nut for the fastening gas pressure shock absorber / "central frame Bicyclejack" and remove the screw afterwards, the old cylinder is now free and the new cylinder can be inserted - the assembly is the opposite of the previous description.

Further details and disposal instructions Subject Gas pressure cylinder (manufacturer's data):


Working temperature range from -30 to +80 °C.

Permissible number of strokes (full strokes) 6 per minute.

Continuous operation after 30 000 strokes: Maximum pressure loss 15%. The continuous running behaviour varies according to stroke length and extension force.

Nominal temperature: 20 °C.

Example for force F1 = 500 N at 20 °C:

+ 35 °C + 5 % = 525 N

- 16 °C - 12% = 440 N


Gas springs are filled with a pressure between 20 and 250 bar and must therefore be depressurized before scrapping.

For safety reasons, the following procedure must be followed:
- Lightly clamp the pressure tube in a vice.
- Saw open the pressure tube perpendicular to the axis in an area between 30 and 35 mm from the pressure tube bottom.


2- Use a hand saw suitable for metal.
3- Place a protective cloth over the saw blade.

Stop sawing as soon as you hear hissing noises.

Degassing is complete when the piston rod can be moved freely by hand.


The filling medium used (nitrogen) is neutral and part of the earth's atmosphere. Its release therefore does not pose a chemical hazard.

The other components (except for the oil) are mainly made of steel. The removal of these components is equivalent to recycling steel.

Under no circumstances may the oil contained in the device be spread in the environment (risk of pollution of ground water) or burned by the user, but must be disposed of in accordance with the relevant national regulations.
