  • Light unit

    5 LEDs with integrated electrical light control and battery management system. The two upper LEDs are protruding, also ensuring the lateral emission of light. The lower 3 LEDs are sunken into the seat post tube. The LEDs, circuit board and battery are enclosed in a plastic housing and are thus protected (dust and splash proof in accordance with IPX5).

    There are 2 modes to choose from:

    - 5 LED mode (all 5 LEDs light up)

    - 3 LED mode / energy saving mode (only the top 3 LEDs light up)

How to Use
  • 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.


    Angle limits

    (Frame seat tube)

    Min: 70.0°

    Max: 76.0°

  • Function

  • Charge state

    Low battery alert

    Indicated by a blue LED integrated into the micro-USB port. As soon as this LED lights up, the battery still has enough capacity to power the LEDs for 1 more hour in accordance with the regulation. The micro-USB port is covered with a transparent silicone cap so that the blue LED is visible.

    Charging

    Micro-USB 2.0 port integrated in the seat rail clamp with a transparent silicone cover for splash-water protection.

    Charging voltage: 5V

    Charging current: 0.5A 2.0A

    In order to reach the full load capacity, it takes about 2.5 hours. During charging, the first led flashes in RED. The flashing stops, changes to continuous red light on when the battery is completely charged. When the battery is fully charged, remove the cable from the USB port. Should the product become excessively hot during charging, stop the charging process. Never charge the battery when the USB port is wet. Full charge and discharge cycles 500.

    Charging time

    2.5 hours

  • Precautions

    At startup, the product must be dry. Remove any moisture before riding.

    After installation, test that the seatpost does not drop under load.

    Take care that the LEDs are not covered by a bag or clothing when riding.

    Do not make any independent changes to the product. Do not try to open the product.

    The product contains one lithium-polymer battery.


    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 microUSB 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.

    If the USB plug has deformed, it must be replaced.
