Bikes are BY FAR the most common cards used in the U.S. Therefore, they are the most NORMAL looking cards for magicians to use in the U.S.
Second to bikes are any other cards made by the U.S. playing card company - which covers a wide range of high quality cards.
Finally, as mentioned, all gaff cards coming out of the U.S. are bikes - putting the rest of the world in a bit of a bind if they want to take advantage of the wide array of available gaffs.
There is a similar "feature" with Kennedy halves. It isn't a very common coin anywhere in the world, including the U.S., but the vast majority of available coin gaffs can be found made from Kennedy halves (and old English pennies). So, there is a good advantage for magicians to use them, especially here in the U.S.
I don't use gaffs much, but I like the commonality of bikes - so I use them mostly.
