The Roam Stroller allows you to lock and unlock the front wheel quickly for easier transitions between running and walking.
To lock the front wheel, rotate the lever to set it at the "straight arrows" icon by pushing down on the lever.
Pivot the stroller to one side until the front wheel clicks into position.
If stroller veers left, rotate the tracking knob clockwise. Meanwhile, if the stroller is veering right, just rotate the tracking knob counter-clockwise.
Disengage the swivel lock by rotating the lever toward the front of the stroller so that the arrow points to the "curved arrows" icon.
