Reykjavik is trying hard to make itself a bike-friendly city. Sharrow are used in many places, and their frequency increases on places like corners and right hand turns where the lanes split to remind you a cyclist may be present.
Bicycles are rarely locked to anything. A cable lock through a wheel so they can't just be ridden off is the norm. Bicycle in private yards don't seem to be locked at all.
Many bikes have front baskets, or child seats, or both.
And some are just pretty.
