Cyclists pay tribute to siege victims

Sydney cyclists of all ages and religions travelled as a united pack to Martin Place this morning to remember the victims of Sydney's siege.

At 7am today, around 100 riders gathered at the memorial site in Sydney's CBD to lay flowers for Tori Johnson and Katrina Dawson who were slain last week just metres away at the Lindt Café.

While 50 cyclists began the journey from Lakemba Mosque at around 5.30am, by the time they reached the city centre the group had almost doubled in number.

"As we rode in the group got bigger," one of the cyclists, Sophie Bartho, told ninemsn.

"We got the most beautiful welcome from security guards [at the memorial site].

"It was a very gentle way of commemorating and bringing people together."

Once the riders had reached Martin Place, many of them laid flowers and signs reading #I'll ride with you.

Ms Bartho, who works at Bicycle NSW, said the Sydney Muslim Cycling Group approached the association with the idea for the ride.

"They just said we're a bunch of cyclists who want to ride to Martin Pace and commemorate Tori and Katrina," she said.

"We had different ages, races all riding together, fully unifying."

She was quick to add that the ride was by no means a media stunt, with news of the ride circulated only to Sydney cyclist enthusiasts.

"This isn't a media stunt. We didn't invite the media," she said.

"It's just a classic example of local people doing something very simple and very sincere idea."

Mr Johnson and Ms Dawson were killed on December 15 by lone wolf gunman Man Haron Monis following a 17-hour hostage siege.

Mr Johnson was the 34-year-old manager of the Martin Place Lindt café while Ms Dawson was a 38-year-old barrister, and mother of three.

Just hours after the siege ended, #illridewithu began trending on Twitter. The tag, seen as a symbol of unifying different cultures, quickly gained international attention.
