Step 2: Update Firmware
Section titled “Step 2: Update Firmware”Initiate a software update. Once the update completes successfully, reboot the bike’s electrical system by disconnecting and reconnecting the battery.
Step 3: Calibrate the Shift Unit
Section titled “Step 3: Calibrate the Shift Unit”Now it is time to calibrate the gear system. Tap the Calibration button in the app. Once finished, test the gears manually using the plus and minus buttons to ensure it shifts smoothly through the entire range.
Step 4: Unpair & Re-enter Pairing Mode
Section titled “Step 4: Unpair & Re-enter Pairing Mode”Navigate to the Unpair Trigger menu option and unpair the controller. Reboot the system once more by unplugging the battery and plugging it back in. This reboot is crucial, as it forces the system back into pairing mode.
Step 5: Pair the Wireless Trigger
Section titled “Step 5: Pair the Wireless Trigger”As soon as the battery is reconnected, press and hold the trigger button at the end of the handlebar until the LED light begins to flash. Once it starts flashing, release the button. Now, verify shifting both directly from the handlebar trigger and through your PC interface.
Step 6: Disable Auto-Downshift (Important Note)
Section titled “Step 6: Disable Auto-Downshift (Important Note)”Make sure to turn off Auto Downshift mode. Since this setup is not on an e-bike, there is no communication with a Bosch motor. Without speed and cadence data from the motor, leaving this setting on will simply reset the value to zero every time you turn the bike off, and automatic downshifting when stopping will not function.
