The new 2012/2013 Mayhem is the superb bike designed and built by Raleigh for serious use by boys between the ages of 6 to 8 years. With its chunky 2 inch wide tyres, shocking day-glo yellow on black colour scheme with coordinated chainguard and handlebar grips, this bike has been carefully engineered to perform as well as it looks. Sure to be a hit with any boy with an inside leg of 20 inches and up.
