Your iBike software can be used to update your Gen I/II/III iBike's firmware to the latest version. (If you own an iBike Dash, firmware is updated through the iBike app).
iBike software is available from the downloads section of the iBikesports website, http://www.ibikesports.com/downloads.html
Note that you'll need an internet connection for the firmware update feature to work.
Your iBike software will check your firmware version automatically whenever you download a ride from your iBike. If a newer version of FW is available you'll see a message displayed.
You can also check manually for firmware updates. Go to "Help/Check Online for Firmware Update".
If your firmware needs updating follow the screen prompts to get the latest version of firmware for your iBike. Make sure to leave your computer and your iBike untouched during the firmware update process!
