A couple years ago, no tools ๐ . I was commuting between home and campus just a mile away, so if something went wrong I'd just lock the bike and come for it later.
Nowadays, just a few to do an inner tube & chain replacement, and some other small bits that might come in handy.
- 2 spanners (one adjustable)
- Backup lights & head torch
- Tyre levers & adhesive puncture patches
- Mini track-style pump
- Screwdriver for the chain enclosure
- Pliers for the rollerbrakes and internal hub gear cables

I've found the head torch to be surprisingly helpful... Had a puncture in the dark once, and without that I would have been there a while lol
I don't commute with any tools. I have pubic transit options throughout my ride, so if I have a mechanical issue it's quicker and easier to lock up, catch a bus or train, and deal with it on my way home. I've only even needed to do this a handful of times in nearly a decade of commuting.
For weekend rides where I'm farther from reliable transit, I'll take a pump, tubeless plugs, innertube, multitool, zipties, and quicklink tool+extra links.
