Acrobike

The Acrobike (アクロバイク) is an electronically assisted bicycle developed in Academy City.

Principles
The acrobike is a electrically assisted bike, based on a mountain bike, with a top speed of over 50kph. It has electronically-controlled suspension which softens impacts and allows the bike to jump over two meters. The disc-shaped gyros sandwiching the front and back wheels provide the acrobike with autonomous stability, keeping it from falling over even if its inclination exceeds seventy degrees.

Cycle Arts
The acrobike is capable of a set of unique high performance acrobatics, known as Cycle Arts (サイクルアーツ). Its specs allow even an amateur to carry out these techniques successfully.

Magic God Invasion Arc
Due to getting carried away around the time of preparations for the Anti-Crime Orientation, Tsukuyomi Komoe purchased an acrobike for her school. It was used by Kamijou Touma to escape from the High Priest, together with Misaka Mikoto.
