One of my more
satisfying purchases last year was a tiny flat compass that clips
perfectly onto the rear center of my handlebar bag's lid.

1.2 inch diameter. Luminescent dial and fluid filled (waterproof).
Good enough for most uses.
Have you tested it for accuracy? I've found the very small diameter
compasses to be very inaccurate. I prefer the somewhat larger
diameter hiking compasses:

The larger diameter oil filled marine compasses are much better, but
are unfortunately unsuitable for hiking and bicycle riding:

I've proven to myself many times that I have no talent for guessing
which way is north. My notoriously cloudy riding area doesn't help.
I haven't tested that compass for accuracy, largely because I don't need much accuracy. My intent is to tell which way I'm pointing, plus or minus maybe 20 degrees.
Example: Many years ago a friend and I headed out for Cleveland, about 60 miles away, using a AAA Northeast Ohio map with unusual detail, to follow some pretty remote roads - e.g. within Amish territory.
We came to one complex 5-way intersection that was not accurately represented on the map and had trouble picking the proper road. A compass would have helped.
For more accurate work I've got a Brunton pocket compass with sights, mirror, declination correction, etc. I was able to use it to locate survey stakes in our forest preserve at distances of up to about 100 feet.
