Police are still appealing for witnesses to the fatal crash which happened on the A710 near Southwick around 1.05pm on Sunday, April 11.
Emergency services attended the scene after a white Peugeot van, travelling west, was involved in the crash with the cyclist riding a black Trek bicycle which had been heading east.
The police have now released the name of the cyclist as that of Helen Renton, who was pronounced dead at the scene.
The driver and passenger from the van were both uninjured.
A Crowdfunder has now been set up to support Helen’s family at this time.
The website states: “This fundraiser is in memory of my best friend, here in Dumfries, Helen Renton. Helen was tragically killed whilst out cycling on Sunday the 11th of April.
"I am hoping to raise money to help with the inevitable funeral costs and to try and give her partner Chris and their wee boy Charlie a wee bit of help in the coming months.
"Helen also leaves behind her older children Jack and Alice.
“Helen simply loved life!
"She is a mother, daughter, midwife, friend and cycling fanatic!
"Her passion for cycling whilst raising money for charity was simply awe inspiring.
"She is loved by many and will be so sadly missed.
"Please help with whatever amount you can.”
Sergeant Leigh McCulloch from Police Scotland’s Road Policing Unit based in Lockerbie said:
“Tragically as a result of this crash the cyclist has lost her life and our thoughts at this time are with her family and friends.
“Several people stopped to help at the scene and our inquiries continue to establish what happened. I’d ask anyone who saw the crash to get in touch with officers as a priority to help our investigation.
“I’d ask anyone who was recording with dash cam on the A710 who may have captured either the van or bicycle prior to the crash, to check their systems and provide officers with any relevant footage as soon as possible.”
Those with information should report this to Police Scotland on 101 and quote incident number 1688 of April 11.
