@Mrklaw https://www.hiplok.com/z-lok-zip-tie/ may fit the bill I have a couple and they are good quality they won't stop someone who really want your bike but for a simple deterrent and stopping someone walking off with your bike. They are fine.
I use the slightly bigger, combination version. I like it. Just a café lock though.
