C. INSTALLATION

•  Refer to Cinch Bottom Bracket install guide  
 

for frame compatibility and Bottom Bracket  

 installation.
•  Refer to Cinch Power Meter spindle installation  
 

guide for correct installation of power meter  

spindle into Cinch crankset.

•  Refer to Cinch crankset installation guide for  
 

correct installation of crankset into bicycle.

D. CHARGING

For charging use a standard USB phone charger. Using the supplied Micro USB cable plugged into a 
USB wall plug is recommended but an alternative Micro USB cable will also work. These are widely 
available and should be rated minimum 500mA (most common). 
 
 

1.  Remove the protective cap using the supplied tool (RF part no. D30512)

2.  Connect the supplied Micro USB cable to the Micro USB charging port on the end of the Cinch  

Power Meter spindle under the protective cap and the other end to a USB charger wall plug or  

USB port on a computer or other device. 

   NOTE:

 You do not need to remove your cranks from your bicycle or the Cinch Power Meter  

spindle from the cranks in order to charge the battery. 

3.  If for some reason you are using a different Micro USB cable be careful that the end plugging  

into the Cinch Power Meter is not excessively thick as it could impact your ability to see that  

the cable connector is going straight into the port and is not interfering with other parts of the  

power meter. 

   NOTE:

 As soon as the Cinch Power Meter is plugged in it will no longer be transmitting data.  

While plugged in the Cinch Power Meter cannot connect to the App, pair with a head unit, or  

transmit data of any sort.

4.  The LED light turns a solid red to indicate that the power meter is charging and the red LED  

light will remain on until the battery is fully charged at which point the LED light will turn off. 

5.  Once the Cinch Power Meter is charged carefully unplug the cable and replace the protective  

cap using the supplied tool.

   NOTE:

 Head Unit Low Battery Warning – Many ANT+ enabled head units display a low- battery  

warning when a sensor, such as the Cinch Power Meter, battery level drops below 10%  

remaining. Once this warning is displayed you still have approximately 10 hours of battery life  

left in the Cinch Power Meter.  When the Low Battery Warning is displayed it is recommended  

that you recharge your Cinch Power Meter.

E.  TURN ON THE POWER METER 

First Use – Airplane Mode

The Cinch Power Meter is shipped in Airplane mode. In this setting the 
transmitting functions have been deactivated and no power is travelling 
through the electronics. This mode is recommended for shipping and 

flying with the Cinch Power Meter. To turn off Airplane mode and allow 

for the transmission of data simply plug the Cinch Power meter using 
the micro USB cable into a live power source.

NOTE:

 In order to conserve power, the power meter will automatically 

turn off and go into sleep mode after 5 minutes of no crank rotational 
movement.
•  To turn on the power meter, simply turn the crank 1-2 rotations 

either way with the bike in the upright position. 

•  The LED light will blink green when the Cinch Power Meter rotates 

but once installed on a bicycle with the protective cap you will not 
be able to see the LED light. 

NOTE:

 When transporting the Cinch Power Meter in a vehicle in sleep mode, the movement can 

possibly cause the transmitting function to turn on. To conserve battery power during extended travel 
it can be advantageous to put the Cinch Power Meter into Airplane mode using the Cinch Power Meter 
App. You will need a power source at destination to turn the power meter back on.
