The Harmony automatic shifter may not be as strong as a standard mechanical shifter, so you may want to alter your riding style if you find you are getting “stuck” in the wrong gear.
Before a steep hill, you may want to switch to ORANGE mode, and rotate the shifter AWAY from you. This will put you in a lower gear before you start to ride up the hill.
If you prefer to stay in the BLUE mode (automatic) - we recommend keeping it set at around ½ way full of blue, and pedal a bit easier at the beginning of a hill, which will allow the system to shift smoothly. Remember to use Pedal Assist level 5 when climbing steep hills.
