A couple years ago, no tools 😅. 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
