A super packet card trick, whereby the cyclists pictured on four 'Bicycle Jokers', dismount and transform into four Kings.
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 any Royal Figure, he's the King of Spades.
Based on this observation, the effect Bikers is crystal and progressively more amazing. Four jokers are slowly displayed, then one after the other, three of them get off their bikes, transforming into Kings as the cards are openly spread between the magician's hands. To finish, the last change happens in the spectator's hand, leaving a fully examinable card.
No table needed, no cards stuck together and the reset is automatic.
