My essentials are:
- lights on my bike: headlight, taillight + wheel accessories; I wish I had these, but these are also pretty good:
- a variety of gloves, mittens, scarves
- a tea pot and teas
- a good book (or two…)
- running and gym appointments
PS: Just saw that tire lights aren’t allowed on the street in Germany. They should be, for the protection of bicyclists!
Can you add any of your own?
