SA driver, 19, jailed over cyclist death

A Sunday morning bike ride was Brenton Curtis's only pleasure outside his family, but his practice of 20 years turned fatal one morning in October, 2017.

Mr Curtis, 62, was riding in Adelaide's north, just minutes from his home, when he was hit by a speeding, drunk driver.

That driver, 19-year-old Garang Akech Luk, was on Thursday jailed for at least one year, eight months after he pleaded guilty in the District Court to death by dangerous driving.

The court heard Luk had been out all night and was driving a friend home when he hit Mr Curtis about 7.30am at Salisbury Plains.

His blood alcohol reading was about 0.12 at the time of the crash, and he had been travelling between 60 and 73km/h in a 50km/h zone.

Outside court, Mr Curtis' son, Ashley, said the family were disappointed at the length of Luk's prison term.

"What more does an offender have to do to get a decent sentence?" he said.

"Twenty months for killing a man is just not enough."

In sentencing submissions earlier this year, Ashley Curtis said his father suffered a serious head injury in the crash, and died in hospital a week later.

His wife, Wendy, told the court she had lost her best friend, soulmate, children's father, grandchildren's grandfather, carer and source of income.

After the sentence was handed down, Mrs Curtis said Luk had shown shown no remorse since the incident.

"He'd gone off to play basketball interstate - how do you kill somebody and go off to play basketball?" she said.

"I've got five grandsons who are all going to be drivers one day - how do you teach them to do the right thing when this is what happens?"

She said her husband had gone for a bike ride every Sunday morning for 20 years.

"That was his only pleasure that he had for himself, everything else he did was for family."

Judge Costello imposed a head sentence of two years, one month, but Luk will be eligible for parole in mid-2020.
