This bike was launched in September 2005 as Tomahawk Rbk
The early versions of this bike had micro adjustment vertical seat and handlebar movement with corner mounted adjustment knob operating a push block to secure, the later style was changed to pop pin adjustment with some models having belt drive replacing chain drive.

The bike was relaunched in February 2008.

The main difference on this bike was the striking colour change

  • Gloss black - Tomahawk E series
  • High gloss platinum - Tomahawk S series.

During the life of this bike the Handlebar and seat posts were changed to aluminium construction.

Early model bikes can be upgraded to the latest style Aluminium parts with the addition of the longer style pop pin and removal of the original push block mechanism.
