I bought a small wallet at the Mega-lo-mart that is suede with a little magnetic flap. I can clip it to my cycling jersey pocket and it stays put, or it is slim enough that I can't feel it in my jeans pocket. It has just enough room for the crtical stuff- driver liscense, debit card, insurance card and a $20 bill. I think it is ideal for bike rides when you don't want the hassle of a tri-fold.
