Platforms here. Main ride is used for transport, groceries and hauling the toddler to school- so no foot retention. I did try some mini-clips (toe only), but even that seemed a bad idea with the child on the back. The other bike is a DL-1 three-speed, so platforms there as well.
Maybe one day, when I finally get the road bike that I'll get after the longtail, I'll use clipless. Or maybe not.
