Hoverbikes were invented by Tinker. Her and her friend got some beat up motorcycles that didn’t have any tires. On Elfhome, tires are at a premium because they are only made on Earth. She used magic circuits to make the bikes fly. They are limited in how high they will fly and some maneuverability. Tinker owns the patent on all hoverbikes because she is the only one who understands how they work. A company builds them in Pittsburgh, but they do not understand what makes them work. However, some teams do modify basic bikes to go faster in the races.

This is a tengu team that tried to kill Blue Sky and Oilcan in the races to win. They also cheated on the bets by knocking out the phone and betting right under the max. They led to the tengu being band from the sport for a while. They are all dead; one was killed by the half-oni, and the rest executed by the tengu.
