Freestyle BMX bike with supercharged frame.

Bike is in very good condition. Purchased May 2011 for $520 (bday present) and my son has only used it to ride to school occasionally. He bought a 50cc scooter August 2011 and hasn't used bike since.

It has 4x pegs (i.e. front and back).

Can deliver if buyer lives on North Shore, Auckland. Otherwise pick up or pay extra for shipping.
