How do I activate/deactivate walk assistance?

Press and hold the minus button on 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. Walk assistance will be paused as soon as you release the minus button. You can reactivate it by pressing the minus button again within 10 seconds. If you pause for longer than 10 seconds, walk assistance is automatically deactivated.
