Finish all manual quests

To manual you must alternate between pressing Forward and Backward to stand on your hind legs, and then continue doing so to keep the line in the middle of the bar (Forward makes the line move up, Backward makes the line to go down). Letting it reach the top or the bottom causes your combo to fail. You can also jump to end the combo at any time.

To complete the achievement you must manual for 3000 points. Make sure to find a nice long straightaway with no obstacles. Extended manualing is extremely difficult to pull off without using Slow Motion, so don't be afraid to use it.
