A packet trick that actually makes sense!
Have you ever looked at the joker in a Bicycle deck? I mean really looked - close enough to see that the royal figure out for a ride isn't just anybody; he's the King of Spades.
Bikers is based on just such an observation, producing a packet effect with an unusually logical premise: the riders from four jokers dismount and transform into four full-sized kings.
Legitimately using only four cards, the effect is crystal clear and progressively more amazing. The method is exceptionally well thought out - no need for a table, no sticky cards, and the reset is automatic.
Comes complete with all necessary cards custom printed by the U.S. Playing Card Company.
