Bosch Purion Buttons 

Understanding the layout of your buttons is important as you can use these in combinations to make your bike do clever things!

The Bosch Purion Power Button is at the very top of the controller, hidden out of view if you are on the bike.

Some bikes have a walking aid turned on, to do this you press the walk button and then the "+" button while HOLDING walk.

Bosch Purion Step by Step Button Controls

  • Change units from miles to kilometers: hold the - key and tap the Power button.
  • Reset trip distance: hold the - key and hold the + key for a couple of seconds.
  • Turn On Lights (if they are wired in): hold the + button for a few seconds.
  • Change Menus as you would in a car, hold the - button (trip distance, odometer, range, assist level). These only reflect which assistance mode you are in. For example, if you are in ECO, it tells you the range of battery using that assistance level. If you are in no assistance it doesn't tell you any range.
  • 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 e-bikes do not have walk mode enabled.
