Baby jogger city select fold mechanism stuck so can't fold pushchair

SOURCE: I can't remove back wheels on a baby jogger 2 buggy HELP!

There are metal clips near the back wheels that go around the black plastic "axle" piece of the stroller. Squeeze the clip to the far side of the axle and the wheels will easily come off.

You have to put the big bar through the wholes in the side attachments first before attaching the spring loaded bar. The big bar should be facing toward the front of the stroller.

Once the bars are all attached, the to clicky slots on the Peg should click into the small cross bar and the spring loaded bar. The big slot on near the back of the Peg should rest on the big bar.
