While visiting the Accell Group in Southern California, I was able to spend some time digging into the Bosch Purion LCD display control pad and wanted to share some of the deeper settings. In this video, I show how to change units from miles to kilometers, how to clear trip distance, how to activate lights, and how to enable walk mode. This display is a lot simpler than the Bosch Intuvia. It is not removable, not very easy to swivel (to reduce glare), and does not have an active Micro USB port for charging accessories... the port is there, but it's only designed to handle software updates unfortunately. I have found that the + and - buttons can be inconsistent to press because they angle in to the right (towards the LCD screen) vs. going straight up and down like the button pad on the Bosch Intuvia and Bosch Nyon.
- The buttons on the control pad include Power (top edge), +, -, and Walk (bottom edge).
- To change units from miles to kilometers, hold the - key and tap the Power button.
- To reset trip distance, hold the - key and hold the + key for a couple of seconds.
- To activate lights (if they are wired in), hold the + button for a few seconds.
- To change menus, hold the - button (trip distance, odometer, range, assist level).
- To activate walk mode, make sure you are in one of the four levels of assist, then press the walk button once and hold the + button to make the motor go. Note that some ebikes do not have walk mode enabled (all Trek models have it disabled as of 2018).

To compliment this video, I have also created a post in the EBR forums with written instructions and pictures which you can visit here: https://electricbikereview.com/forum/threads/bosch-purion-ebike-display-settings.16253/
