I eventually found that my bike fit in it's carry bag with the pedals detached, so I thought "why bother?". I installed a set of Shimano XTR SPD pedals and simply leave them on. The bike folds properly, fits in the bag, and the pedals don't poke me any more than the other protruding bits.

I don't like to ride with pedals that I can't affix to my shoes. Riding without cleated, clipless pedals, or clips and straps is less efficient, and allows me to use half the muscles in my legs. I don't know of any folding pedals to which cleats, clips, or straps can be attached, so they are not an option for me.

Of course, when riding with clipless pedals, or clips and straps, slippage is generally not an issue, but it does limit your option for shoes somewhat.
