I. Installing the Hicycle App

• For Android Users: Install the Hicycle app via the Google Play Store.

II. User Registration and Login

• Open the app and register your account:
  • Click on the desktop icon → Register → Enter your email → Receive and enter the verification code → Set your password → Click Register.
  • If the verification code expires, simply request a new one.

III. Connecting Your Altis Sigma Bike

  • Tip: If connection fails, manually unbind the bike through your phone's Bluetooth settings, then restart the Hicycle app.

IV. OTA Firmware Upgrade

• After connecting your Altis Sigma bike to the Hicycle app, an automatic OTA upgrade reminder will pop up.
• Confirm the firmware upgrade and watch as your bike enters the upgrade interface. The screen will go black briefly as the upgrade progresses.
• Once the upgrade is complete, the system will return to the main interface and the app will confirm that the upgrade is successful.

V. Wheel Diameter and Reduction Ratio Adjustments

• For correct wheel settings:
  • 16-inch rear wheel: Set to 16 inch, 8.3.
  • 19-inch rear wheel: Set to 19 inch, 7.4.
