Violent youth gangs with names such as the Gold Coast Brotherhood and Soldiers of Islam are springing up on the Glitter Strip as ''feeder groups'' for outlaw motorcycle clubs.

Police say few of the ''bikies on training wheels'' actually ride motorcycles but are causing mayhem, bashing innocent people and committing other crimes in a bid to prove themselves to senior bikies.

The Soldiers of Islam gang, comprising mainly young Muslim men including former Iraqi soldiers, is a feeder gang for the Bandidos bikie gang while the Gold Coast Brotherhood is a recruiting base for the Nomads.

Members of the Brotherhood were allegedly involved in last month's wild street brawl at the Cooly Rocks On nostalgia festival at Coolangatta.

The brawl, also allegedly involving trainees for the notorious Finks bikie gang including former NRL player Anthony Watts, left a 62-year-old bystander in hospital and a classic car damaged. He was bashed after trying to photograph the melee on his mobile phone.

The man charged with assaulting him, Jacob Little, 22, was named in court as a member of the Gold Coast Brotherhood.

Police say the Brotherhood have been involved in various violent incidents on the southern Gold Coast, including surf club and pub bashings.

Gold Coast police inspector Greg Baade, who heads the southern Patrol Group, said the Brotherhood formed in about 2009 but had become ''more active'' in the last two years. Police were now cracking down on them as part of a war on outlaw motorcycle gangs.

Insp Baade said the gang had at least 16 members, ''a number of them known to police''.

''As a general rule, they don't own or ride motorbikes but they do have meetings at various premises around the Coolangatta/Palm Beach area,'' he said.

''They call themselves the Gold Coast Brotherhood or GCB and also use the numbers '14' and '732' as gang logos, some of which they have tattooed.

''Both uniform and plain clothes staff are actively targeting members of various groups including this one.''

The Gold Coast Brotherhood is the latest youth gang to emerge on the southern Gold Coast, where gangs including the 'Palmy (Palm Beach) Army' and Coomicubs - a one-time feeder group for the Lone Wolf bikie club - have run riot in the past.

Police have compiled detailed intelligence not just on the Gold Coast's nine main bikie gangs but also on their ''youth wings''.

Insp Baade said the new Mobile Deployment Group, ''a flying squad'' of battle-hardened police targeting crime across the Coast, had been tasked for a ''zero tolerance'' crackdown on bikie feeder gangs.

He also called on pub and club operators to ''take a strong stance and not allow these types of people into their premises''.
