Members of Windsor Business Group have expressed their concern about colour-wearing motorcycle gang members, particularly from the South Windsor-based Life and Death gang, drinking at the Macquarie Arms on weekends.

Some owners have claimed the bikes and their leather-clad riders, who often sport club logos, are intimidating to families.

"A lot of families who come to Thompson Square feel really intimidated by the presence of that many bikies, which isn't good for other businesses trying to stay afloat," a business owner, who didn't wish to be named in the article, said.

"Often when the bikies leave they roar along George Street as a group taking up the whole road; it's dangerous for families. We have people ducking into our shop terrified when the engines start. They ask "is it always like this?".

But a Life and Death spokesperson said despite their loud motorcycles, people didn't have to be afraid of them.

"There are quite a few of us who go to the Macquarie Arms on a weekend with our families because it's both a family and bike friendly pub," Life and Death member Mick Barker said.

"Being a bikie is a way of life, but it doesn't make us bad people or criminals."

Mr Barker said in the past Life and Death members had aided the Macquarie Arms when it came to security and safety for staff.

"One time a man tried to rob the hotel armed with a machete while we were there. We protected the bar staff, stopped him and held him until the police arrived," he said.

Macquarie Arms licensee Paula Glew said in the eight years she'd been working at the Arms, she'd always found bikies to be well-behaved and respectful.

"We get a lot of different groups and clubs, from Ulysses members to Harley Owners Group members as well as Life and Death guys. They all wear logos of some kind and we're not against that because there's been no trouble at all from bike riders," she said. "Each rider is treated like any other person ? if they create a problem, they'll get kicked out like anyone else."

Ms Glew said she understood how some people could feel intimidated by the presence of Life and Death bikers, but said she didn't think people needed to be.

"In my opinion they are all really nice people," she said.
