Assembly

Use the correct diameter corresponding to your bicycle frame.
Use the appropriate tool to fasten the saddle support.
Adhere to the safety lines of the minimum and maximum insertion heights.
The rear light may only be operated in the following angular range: Max 76˚, Min 70˚.
The lower two LEDs may be sunk in the frame. Always pay attention to the mechanical stopper of the maximum insertion depth!
The rear light must be mounted in such a way that it is illuminated at the rear. The reference axis (see drawing) must be aligned parallel to the bicycle‘s longitudinal axis.
The two lower LEDs may be inserted into the frame. The minimum insertion length into the frame is 100mm. The rear light must be aligned so that it shines backward. The reference axis (see drawing) must be aligned with the longitudinal axis of the bicycle. A mechanical stopper prevents the insertion of the seatpost to cover the 3rd LED(from the bottom) and damage to the two top protruding LEDs.

Steps to take in

the event of a failure

If either LED no. 4 or no. 5 is defective, the mode must be switched to the 3 LED mode to conform with the regulation. Repair or replacement is nevertheless recommended. If LED no. 1, no. 2 or no. 3 fails, the seat post must in any case be sent to the importer for repair or replacement.
If the rear light is defected, it must be immediately replaced.
If you ride with the seat post low, it may be the case that the seat clamp covers one of the lenses. Please ensure that the clamp area is not directly tightened on to the lens as per the illustration below.

USB port

When fitting the saddle, please make sure that the small transparent rubber cap for the micro USB connection is clamped under the strut.
Do not pull on the charging cable excessively.
If the USB connector is exposed to heat, it may lose its shape.
We recommend using the supplied USB cable to ensure proper battery charging.
If you use another cable, please make sure that it is an original Micro USB cable, in the dimensions 10mm wide and 7mm high.
