Loose jockey wheels.
Jockey wheels have an annoying habit of coming loose, usually because they weren’t tightened correctly after cleaning. That piece of copper wire or the 5mm bolt you’ve got can now do its thing. Just loop the cable through the centre of the jockey wheel to keep it in place.
Badly slashed tyre.
Use your handy survival kit duct tape and install a slightly larger piece overlapping the bead of the tyre , thus anchoring it securely when inﬂated. You might want to put a second layer, or even use the piece of cloth or tyre casing, which you also happen to have in your box of tricks.
Broken seatpost clamp.
Re-attach a saddle to a seatpost when the clamp bolt has broken using zip-ties, but sit on it gingerly for the ride home. It’s not perfect but better than sitting on a seatpost.
