From the adrenaline-pumped intensity of BMX racing to the mind-boggling skills and free expression of BMX flatland, we explore 2 very different disciplines in the world of extreme cycling sports. BMX racers reach speeds approaching 60km/h as they hurtle down the start ramp and jostle for position. We see how Japan's racers are working to close the gap on their international rivals, while Japanese flatlanders push the limits of technical wizardry as they make their bikes dance, twist and spin.
