Mannum has lost a husband, father, grandfather, community leader and a gentleman.
Mid Murray councillors will pause at their monthly meeting on Tuesday morning to remember Cr Steve Wilkinson, killed while cycling along Hunter Road at Younghusband on Friday.
Cr Wilkinson, 67, died after his bicycle was allegedly hit by a ute driven by a 73-year-old Palmer man near Chambers Hill Road just before 8.15am.
The driver was not injured in the collision.
Mid Murray Mayor Dave Burgess described the news of Cr Wilkinson's death as "awful, disappointing, heartbreaking, shattering".
"He was a dedicated community person who was always willing to listen, assist and advocate for genuine people," he said.
"He didn't need to be known, he just needed to help.
"Even when things in the council chamber didn't go his way, he didn't need to grandstand, he just got on with delivering whatever was decided."
He was an active member of cycling group Mannum Peddle Wheelers, the town's bowling club and rowing club, sang in a church choir and volunteered with his local Country Fire Service brigade.
He had worked as an accountant and as a manager in the local government sector prior to his retirement, and had served on Mid Murray Council since 2014.
He also served on the Murray Bridge council during the 1980s.
Mid Murray Council closed its offices on Monday morning out of respect, and the flag at Mannum's war memorial on Randell Street was lowered to half mast.
Cr Wilkinson is survived by his wife Debbie, children and grandchildren.
A byelection will need to be held to fill his place on the council.
SA Police Superintendent James Blandford described the accident which claimed his life as a tragedy.
"This fatality brings with it more tragedy for another family who have to deal with the death of another family member," he told Nine News Adelaide.
"A small community (where) these two people are known has to deal with not only the tragedy of a death, but the tragedy of a person who is now being investigated and has to live with the fact they've been in a fatal accident.
"It makes you wonder how much harder we have to work to get the (safety) message through to our community."
Police have asked anyone who saw Cr Wilkinson on his black Bianchi bike, or the red Nissan ute, on the day of the crash to call Crime Stoppers on 1800 333 000 or visit crimestopperssa.com.au.
Cr Wilkinson's death was the 32nd on South Australian roads this year.
