How do I activate/deactivate walk assistance?

Press and hold the minus button of the LED Remote or Mini Remote for longer than 1 second and move the eBike. Walk assistance remains active as long as you keep the Minus button pressed. As soon as you release the minus key, the walk assistance is paused. You can reactivate it by pressing the minus key again within 10 seconds. If you pause for longer than 10 seconds, walk assistance is automatically deactivated.
