1. General information about the POWERCRANK power meter

POWERCRANK is a device used to measure the power generated by a cyclist. Data registered and processed by the POWERCRANK device is made available through ANT+ and Bluetooth Low Energy protocol. The POWERCRANK device is compatible with bicycle computers and mobile devices supporting ANT+ or Bluetooth Low Energy protocols (a list of compatible devices is available on inpeak.pl/en/support_en/).

2. IMPORTANT information for the user

POWERCRANK device should not be washed with pressure washers that generate high pressure water jet. Directing the water jet to the device can damage it.
Do not use abrasive detergents to clean the crank with the POWERCRANK power meter, which may cause damage to the housing and electronic system.
The battery life may be shorter at low temperatures than when the device is operated in conditions that are close to room temperature.
Calibration (see point 6) should be carried out relatively often, especially after changing weather conditions – this will ensure correct indication of the POWERCRANK power measurement. Calibration should be carried out each time after disassembly and assembly of the device on the bike (screwing to the axis of the crank) and battery replacement.

4. Device assembly/first start/battery replacement

a. Unscrew the cover in accordance with the arrow placed on its front (see photo 1).
b. Insert the CR2032 battery into the cover of the POWERCRANK device as illustrated on the cover.
c. Make sure the o-ring is in the right place (see photo 2,3).
d. Make sure that dirt (mud, water, dust) does not get into the battery compartment – if it got, remove it carefully using a soft cloth or a cotton bud.
e. Insert the cover into the housing so that the red marks on the housing and the cover coincide (see photo 4).
f. Push the cover into the housing and turn the cover against the opening direction (see photo 5).
g. Install the left arm in accordance with the manufacturer’s instructions, tightening it with the strength determined by the manufacturer. Use a torque wrench for this purpose (see photo 6).
h. Mount the pedal.
i. After each assembly of the crank or battery replacement, calibrate the device according to point 6.

5. Compatibility of the POWERCRANK device with bicycle computers and

other mobile devices

POWERCRANK is compatible with bicycle computers and mobile devices supporting ANT+ or Bluetooth Low Energy protocols. A detailed list of compatible devices can be found on the manufacturer’s website inpeak.pl/en/support_en/.

If you are owner of the left-sided POWERCRANK powermeter:

ANT+ pairing

Each POWERCRANK device has its own unique ANT+ number. The number is placed on the crank arm and on the packaging. The number should be entered in the field intended for that in the bicycle computer. A description of this procedure can be found in the bicycle computer manual.

Bluetooth Low Energy pairing

Connection with Bluetooth-equipped mobile devices is achieved by activating the Bluetooth function, and then launching a training mobile application that supports the “Cycling Power” sensor via Bluetooth Low Energy. A description of this procedure can be found in the manual of the mobile device.

If you are owner of the dual-sided TWiN2 powermeter:

Pairing via ANT+

The TWiN2 dual-sided power meter advertises itself in ANT + communication as one device with an ID assigned to the left arm. To add the TWiN2 measurement to the bike computer, check what ANT + ID sensor on the left arm has, and then select it from the list of power sensors found by the bike computer. Attention! The sensor on the right is not visible for bike computers in ANT + communication. The sensor on the left in ANT + communication emits data from both sensors (total L + R power).

Pairing via Bluetooth Low Energy

The TWiN2 sensor in Bluetooth Low Energy communication will be announced as two independent devices with the following names: “POWERCRANK L.XXXXX” and “POWER CRANK R.XXXXX” where XXXXX is the 4 or 5 digit ANT + ID number. Sensors L and R independently emit the measured power for the corresponding leg. By default, “Zwift compatibility” is enabled for the TWiN2 measurement which causes the sensor on the left arm announcing itself as “POWER CRANK L.XXXXX” to emit the power value from both sensors (total power L + R).

6. Calibration of POWERCRANK device on the bicycle

a. Put the bicycle in the driving position (see photo 7).
b. Start the device by turning the crank twice back.
c. Make sure that the battery is not discharged.
d. Position the left crank arm vertically with the pedal down (6 o’clock) according to Fig. 7 and make sure that no object touches the left arm. The pedal must be screwed to the left arm.
e. Pair the bicycle computer with POWERCRANK by entering the ID number placed on the crank or on the packaging in the ANT+ options.
f. Run the ZERO OFFSET calibration function on the bicycle computer.
g. A message indicating that the calibration has been completed, and the value of the calibration process, which should be in the range of “-2” to “2” (for left-sided POWERCRANK power meter), or “1010” for an dual-sided POWERCRANK TWiN2 power meter. This process can take up to several dozen seconds. If this value does not fall within the given range, contact support@inpeak.pl.

After the calibration process, the device is ready for cycling.

NOTE:
Calibration should be performed relatively frequently, especially after changing the weather conditions – this will ensure correct indication of POWERCRANK power measurement. Calibration should be carried out each time after disassembly and assembly of the device and replacement of the battery.

7. Software update

Software updates are posted on the manufacturer’s website in the support tab inpeak.pl/en/support_en/. POWERCRANK supports the over-the-air (OTA) – wireless software update. More information can be found on the manufacturer’s website.

8. Cleaning/care of the device

For cleaning, use water with mild cleaning agents, e.g. soap, lotion, shampoo for bicycles washing, etc.
Do not use pressure washers for POWERCANK device washing (see point 2).
Do not use aggressive substances for cleaning – solvents, etc.

9. Recycling

Protect the environment! Electronic equipment does not belong to household garbage. Use the collection points provided for taking off the electrical equipment and return the equipment which will no longer be used there.
Information on where to dispose the used equipment can be obtained at regional municipal offices or in the municipal administration.
