Daredevil River Mathias is the UK’s youngest motorcross racer – aged just four. The fearless youngster started riding motorbikes before he could even walk and now races against kids more than twice his size and age.
River tears up the tracks hitting speeds of 25mph on his souped-up electric dirt bike worth £4,000. The bike-riding fanatic, from Kempsey, Worcs., wants to follow in the footsteps of petrol-head dad Craig who also races motorcross.
Craig, 37, said: “It started when it was his first birthday, I bought him an electric quadbike. He just got on and rode it.
