On the level Meet Contact you will be riding the speeder bikes the whole time. Most of the time when an enemy pulls up next to you you'll just pull out the good old lightsabre and let him have it. Well there is a way to jump onto his bike and
throw him off. You travel side by side at the same speed, and you must be going in a straight line. When you are set hold the left thumbstick towards the enemy and press jump. You'll leap off of your bike onto the enemy's shoulders and do a frontflip, tossing the enemy away and landing on the bike. It doesn't work every time and it's not as efficient as using your lightsaber, but it looks a whole lot cooler.
