Chosen Solution
I recently put together a kids big wheel and the steering column is very stiff and will hardly turn. Obviously this isn’t something that is adjustable given the set up, but I need simple solution so my three year can steer it. Thanks!
Try adjusting the height of the handlebars by loosing the screw in step #5 of this PDF and lifting slightly till it turns freely then tighten it back down: originalbigwheelparts.com/images/bw_assy_instructions_pictoral.pdf
Neither of the above helped a bit. Cannot be steered by a child.
