It’s probably optional for bike shops. I have gotten 3 yellow pieces of paper from 3 different stores within the last year, and all of them seem identical, except for the store name; which is stamped on it. I have gotten these from Target, Dick’s Sporting Goods, and Hudson Trail Outfitters. Seems to be the same generic bike registration form. I know that Performance Bike also provide the same yellow paper. If a seller doesn’t have it, a receipt would suffice, but they generally don’t show the serial number, so buy at your own risk…
Hmm. Every bike receipt I’ve gotten does have a serial number on it (actual bike stores). The bottom line is that I would not generalize what sort of paperwork someone should have with their bike.
