Nigel Sylvester has spent years turning BMX into a first-person language. Through his “GO” series, the New York rider took cameras onto bikes, through streets, cities and unfamiliar places, giving viewers a direct view of the speed, risk and improvisation that define his world. His latest project, “Brick After Brick”, continues that story from a different angle, looking at the career, culture and ideas that have made Sylvester one of BMX’s most recognisable figures.
