How to install the front wheel?

There is a quick release skewer for installing the front wheel, place the front wheel on the wheel hub, then tighten and lock the quick release skewer.

There is a spring on each side of the quick release skewer. The small end of the spring is inward, and the big end is outward. The nuts on the front wheel do not need to be removed.

In addition, please make sure both sides of the fork are clipped on the hub, not on the quick release skewer.

*Please check the tire position before and after inflating the tire, inspect the wheel to make sure the bead seat line is aligned to the rim, the bead is uniformly seated, and the inner tube is not poking out from the underneath of the tire.

How to install the pedals?
