The Signal Bikes (シグナルバイク Shigunaru Baiku) are miniature bikes used by Kamen Rider Mach and Kamen Rider Chaser in conjunction with their belt, the Mach Driver Honoh. Some Signal Bikes enhance Mach's current form with a Signal Exchange (シグナル交換 Shigunaru Kōkan), adding the last part of a Signal Bike's name to its original name (i.e, Mach Magarl). Signal Exchanges also influence his Zenrin Shooter with different shooting capabilities depending on how many times the Mach Driver Honoh's Boost Igniter button is hit. Unlike Drive's Tire Exchanges, Mach's Signal Exchanges are nowhere near as flashy, and the Kourin Signal merely appears on his Signal Kourin. It is currently unknown if Chaser is capable of Signal Exchanges as well.
