The Mach Bike allows players to move a lot faster than regular Bicycles and the Acro Bike (16 steps per second in Generation VI). It can move fast enough to ride straight up muddy slopes, or over cracked tiles without falling through (which appear in Granite Cave, the Sky Pillar, and Mirage TowerE) if the player has enough momentum. If the player collides with something, all momentum gained is lost and the speed resets.
On the Seaside Cycling Road, a player's time and number of collisions while riding this Bicycle from the northern entrance to the southern exit are timed and recorded. This is part of the data sent over to other players via record mixing.

In Dreadful Dealing with Dusclops, Wally used a Mach Bike left for him by Norman at the base of the Sky Pillar to quickly ride over the cracked floors in order to scale up the tower. When Wally reached the 49th floor, he encountered a wild Dusclops, which created a black hole, sucking in the Mach Bike before being defeated by Wally's Grovyle.
