NST was developing a motorcycle game utilizing the Wii Balance Board.
According to a patent filed by Nintendo with the US Patent and Trademark Office, Nintendo Software Technology, the developer behind the Mario Vs. Donkey series, as well as the cancelled Project H.A.M.M.E.R., was at one point developing a motorcycle game for the Wii that utilized the Wii Balance Board.
In the patent, it is seen that the game would have had players stand on Wii Balance Board and use the Wii Remote and Nunchuk as handlebars. The game would have been played in a first-person perspective, putting gamers in the shoes of the rider.
