A motorcyclist who died in a crash on the A4109 in Neath Port Talbot has been named as 40-year-old Gregory Flowers, from Neath.
Two other vehicles travelling in the opposite direction were involved in the collision with his motorbike, at around 8.30am on Wednesday, between Crynant and Aberdulais.
His wife, Liwsi, said: "My husband was a loving father of three children, Kyle, aged 20, Kira, 17 and Carys, 13. He was a loving husband of the late Angela Flowers."
“Greg was a close brother to Andrew, Alan and Matthew, son of Neil and Ann, grandson of Phylis and the late Gwyn Thomas, also grandson to Nancy and Harold Flowers."
“My husband was a loving and caring person who was larger than life, always smiling and loved by every person who came into contact with him."
“He was well-known in our local village and places he worked as a prison officer and later a probation support officer."
Greg’s son, Kyle, said: “My father was an amazing father and a positive influence on my life, together with my sisters’ lives. I would describe our dad as our best friend as well as being our light and strength. He was the shining light for all the family.”
Greg’s mother, Ann, added: “Greg was the sunshine of my world, always happy and helpful. No-one will ever replace him in this world. He gave the best hugs on numerous occasions, any time of the day and night."
“Being a mother to Greg and his brothers has been the best job in the world. I have been privileged and lucky to have had Greg in my life for 40 years.”
