The Rumble Bridge Motivator is a motivator along with the Big Balls and obstacle in Wipeout starting from season 3.
The Rumble Bridge first appears as an obstacle and is colored red with a narrow ledge. Because it's name implies The obstacle was designed for anyone who got close to the second Rumble Bridge would tip in 2 ways. If contestants ran at fast speed, the first one would move down while the second move upward smacking contestants in the face. If contestants run but not as quick, the 1st Rumble Bridge will shake contestants up and down until they fall in the mud. If the contestants are on the other Rumble Bridge during this they will deliver one last hit to contestants to finish them off. Nobody got past the obstacle by itself
In Season 4, the Rumble Bridge makes a huge appearance and is common mostly in Summer Wipeout. First it reappeared as the name "The Winter Wonder Planks" as it was a winter episode with minor differences; the Planks had more space and if contestants stood on the first one too long, the planks launch the contestants in the air until they fall in the mud. There were also three instead of two planks. Still nobody got passed. Later it reappeared commonly as a platform on the obstacles. As a platform, it first appeared in Spring Training and attempted to flip contestants in the water. The Rumble Bridge was much larger and had more width to stood on. On episode 5 of Summer Wipeout, it served as a flipping platform on the right when ever contestants jumped off and was joined by the Wheel of Misfortune obstacle. Few episode later, it came back, and again, like the last time was a flipping platform and joined an obstacle, this time Ballsy's Playground. Although nobody got passes the Fly Swatters, it returns but was not used as no one got to the Rumble Bridge. Again in the next episode and obstacle, Double Bubble Trouble, The Rumble Bridge returns with the same mechanics for the obstacle. Next it reappeared one last time in Season 4 on the Wipeout Video Game Spinner.
Season 7 Edit
In season 7, the Rumble Bridge is appeared using a crop stair circle to hit the contestants at the back of their heads to push them into the platform. The platform has a foam and a shaking motion to slip away the contestants so they wipeout into the water.
