To put it back up...

Step 1.

Take the chassis out hold the handle, put it on the ground with the handle up, grab the front axel, and push on it to unattach it from the back axel, then grab the handle lift quickly and the front wheels should flick out, and drop to the ground, this is the trickier bit, but once you get it you will find it really easy
This is the hardest part, the video shows that you just pick it up and it flicks out easily which is totally wrong, it's quite sticky and you do need to push it as per Beema's instructions.

Make sure you have a play around with it, not like me who tried to put it together for the first time in a busy Coles carpark with a 2 week old and looked like an idiot.
