We meet BMX racer Ti, who became number one in his age group last year. However, this season he is struggling - can he fight his way back and reclaim his title? We also meet Adele, who is coming out of a race ban - will she be able to control her temper and race back to winning ways?

Before he competes in the Nationals, Danny-Jake has a daunting task ahead of him - can he jump some of the biggest BMX jumps in the world? And can Erick secure his dream job as a mechanic?
