So apparently no one knows how to ride a mountain bike on sand, since every time I search for tips online I get a bunch of vague nonsense about keeping your weight centered and using the right tire pressure. Like, thanks for the obvious advice, experts. But seriously, how do you actually navigate sandy terrain without coming to a complete stop or wiping out? Is it even possible? Are the YouTube videos of people cruising through the dunes just highly edited magic? Do you need to have some kind of special bike or suspension system that no one ever mentions? And whats the deal with the whole unweight the front wheel thing - how are you supposed to do that while still maintaining some semblance of control?
