Forms
Mach "Signal Bike! Rider: Mach! (Groovy music)"

- Transformation announcement

Ability Perimeters: Accessed through the Signal Mach Bike, Mach's default motorbike-based form bears the Signa Kourin (シグナコウリン). Like Drive, Mach is able to create intense Heavy Acceleration distortions through verbal command.
 * Height: 205.5 cm
 * Weight: 96.6 kg
 * Punching power: 9.7 t.
 * Kicking power: 16.7 t.
 * Maximum jump height: 40.3 m.
 * Maximum running speed: 100 m. per 2.4 sec.

Since Mach's V-Helm (∨-ヘルム) helmet is based on a motorcycle helmet, the Innovate Visor (イノベイトバイザー) part of it can be raised up to reveal the Shutter Face Guard (シャッターフェイスガード), which lets out the pent up energy that Mach builds up during extended use, as well as being the manual off-switch to his Heavy Acceleration abilities

In this form, Mach has serious power, punching and kicking harder than Drive's Type Technic Braver and Gravity, as well as Type Wild (though not Types Wild Dump and Wild Wrecker), can jump higher than Drive, and is almost as fast as Type Speed when Drive goes at full speed. Mach also has the ability to hover in the air for a short period of time by jettisoning power through well-hidden vents along his thighs.

By hitting the Boost Igniter four times, Mach is able to summon his Zenrin Shooter. If he does so while already having the Zenrin Shooter on hand, he instead gains the ability to accelerate at an incredible running speed. This speed is enough to follow and fight against Faiz Accel's speed, as shown in the movie . It is also proven that he can use this ability without summoning the Zenrin Shooter first.

Mach's Full Throttle finisher is the Kick Macher (キックマッハー), where he gathers energy into his feet, then runs forward and jumps up. Afterwards, Mach somersaults like a buzzsaw, spinning until he reaches the target. Just before he makes contact, Mach extends a foot out to strike the target.
