I'm not here to advertise, but I think this video will give you good help, I've watched it before.
While the video will help , telling you on here may make it quicker. The mach bike can turn quick enough to make it work but here is the problem. You have to go at max speed and you can't stop because if you do the floor will break. It requires a lot of skill to do it right and I'm happy they got rid of it in the delta episode.
