The Parramatta-based Brotherhood Christian Motorcycle Club, who describe themselves as a non-violent, law-abiding group of committed Christian motorcyclists with a focus on community outreach, have joined forces with 17 other biker groups, some of which bear names that engender fear in some people.

The clubs are all members of the United Motorcycle Council which is fighting to overturn the laws.

Brotherhood spokesman Grant Howard said the organisation was proud to stand with other clubs, including the Bandidos, Comancheros, Hells Angels and Gypsy Jokers to oppose the Crimes (Criminal Organisations Control) Act 2009.

Mr Howard said the clubs could no longer ``stand on the sidelines'' because the community needed to understand the wider implications of the laws.

``Our position is not a support for any criminal activity, but rather opposition to unfair, knee-jerk legislation that damages the fundamental rule of law and presumption of innocence in Australia,'' Mr Howard said.

``This legislation does not mention bikers, and can be used to silence any group including religious denominations, environmental groups or trade unions.

``Existing criminal law in Australia is more than sufficient to deal with any criminal activity within society or the motorcycle community.''
