Yes, wheel bouncing is a technique they teach in this.Wait, there's people complaining about how the extreme tracks feel more cramped and less fluid than beginner-mediums? That's kind of the entire point. To make obstacles more precise and make you think more about them. There are plenty of user tracks that rely on fluidity to get over extremely difficult objects. There is almost no innovation left to be found if you include user tracks. If you can't do extremes or find them frustrating there's still a wealth of content and a robust track editor for endless content. The game would be worth the price even if you couldn't do mediums.
Please tell me "Rear Wheel Bounce" is referring to the ninja technique. That shit is so difficult and I need to finally learn how to do it.
