Yu-Gi-Oh! 5D's (遊☆戯☆王5D's (ファイブディーズ) Yūgiō Faibu Dīzu?) is a new Yu-Gi-Oh! series which began to air in Japan from April 2, 2008, and replaces Yu-Gi-Oh! Duel Monsters GX (broadcast as Yu-Gi-Oh! GX in the US)
During the series, the main Duel Disk is a motorcycle called a "D-Wheel" and duelists engage in stadium games called "Riding Duels". The 18 year old main character, Yūsei Fudō, has "Stardust Dragon" as his main card, which is the cover card for the Duelist Genesis trading card set.
The latest Yu-Gi-Oh series features the "Riding Duels". An all new style of duel in which the players ride the D-Wheels, motorcycles with Duel equipment. Contrary to the previous series, dueling with D-Wheels contain some special rules. First, the duel is entirely played using the field magic "Speed World". Second, only magic cards designed to work into this field are allowed in the duel. Each magic needs a number of "Speed Counters" to be activated. Each duelist starts with zero Speed Counters and its number increase by one in each standby phase. A player's Speed Counters are reduced by one for every 1000 points of damage done to their LP. When a winner is decided, the D-Wheel of the defeated duelist shuts down automatically.
The D-Wheel features the card platform, sitting in front of the duelist, a stand for the cards in hand, which allows the duelist to ride with one hand while using the cards with the other, and a compartment for the deck located in the player's wrist. Cards sent to graveyard are inserted in a slot also located in front of the duelist.
In some D-Wheel models (called hybrid models), the card platform can be detached from the bike and function as a standard Duel Disk for old-fashioned duels.Jack Atlas's D-Wheel monowheel
