@HayiWena@dr2chase@meganL the xtracycle edgerunner (now replaced by "swoop" with slightly lower step-thru) has a 20in rear but if you can roll over something with the 26in front, you can usually ride it out, though I generally stop/slow and crank the rear wheel up a curb if it's over ~5in, depending on how much load is on the back. I have a 10sp derailler but one might want an IGH on that if concerned about catching sticks and leaves in it.
