Youin XL3 — Handlebar folding/unfolding and assembly procedure

Pasos

1. Official steps (manual, this model's assembly section lifts the folding lock, pulls down the handlebar tube, and folds the handlebar with a hook mechanism - worded slightly differently from the buckle/rotary-knob mechanism described for XL MAX / XL MAX Lite, recorded as this model's own procedure rather than assumed identical).
