Motorbikes were created by Giannini as an alternative travel mode in Choice to hide the participating Vongola members from the Millefiore's radars. Giannini stated that the motorbike was a model that he admired for its racing skills. Using new technology, he had modified it. As for fuel, after activating the Dying Will Flame, its wheel power would increase. Giannini adds that he also used the invisibility power of the Mammon Chain to hide Dying Will Flames from Dying Will Flame radars.
- In the anime, the Vongola Choice members used airbikes instead of motorbikes.
