Melissa Hoskins was remembered as a tremendous Olympic cyclist, a doting mother-of-two and a fun-loving spirit with a legacy that impacted millions.

Mourners who came to lay the 32-year-old to rest in her hometown of Perth on Wednesday afternoon were encouraged to celebrate her.

Hoskins died after she was struck by a car allegedly driven by her husband, Rohan Dennis, outside their Adelaide home on December 30.

Dennis and their two young children were among the funeral attendees at the Fremantle Cemetery.

Hoskins' pale wooden casket, adorned with a sunflower wreath, was carried into the West Chapel to strums of country music.

Hoskins' father, Peter, trembled and sobbed when he got up to read his eulogy.

"Melissa's zest for living touched so many people," he said.

"We're celebrating a life today that was cut way too short. Melissa was just warming up. Her best performances were yet to come."

Attendees were told of Hoskins' joyful upbringing as a kid in the Perth Hills suburb of Kalamunda.

It was a childhood full of climbing trees and bike riding with her sister, Jessica, before she shot to success as an athlete.

"At the age of 15, Melissa's life and ours changed forever," her father said.

"Having been identified by Carmel College as a student with athletic potential to join the WAIS (WA Institute of Sport) cycling program."

Hoskins represented Australia at the 2012 and 2016 Olympics, and won gold in the women's team pursuit at the 2015 World Championships.

'A champion mum'

She announced her retirement in 2017, and soon after started a family with Dennis.

Hoskins' young daughter cooed at her grandfather's feet as he continued his eulogy — telling the sobbing crowd of his daughter's dedication to her family.

"When Melissa retired, she reset her goals," he said.

"It's time to become a champion mum … Mel was the rock for her family."

Mr Hoskins said his daughter was "taken too soon".

A short and poignant message to Hoskins from her mother was also read out by Mr Hoskins.

"I miss you everyday," it read.

Mourners heard Hoskins loved music, dancing, cooking and gin and tonics.

They were encouraged, if they wished, to have the beverage in her honour at the wake.

Hoskins' sister Jessica followed their father's eulogy and was equally emotional.

She reminisced about their childhood and warm memories from later in life as young mothers.

"I will always think of you when I'm cooking as the kitchen is a happy place for both of us," she said as tears streamed down her face.

"Vegemite and honey on toast will now be known as the Melissa breakfast."

Hoskins' former coach Gary Sutton spoke of his privilege to work with the cyclist — who shone brightly on and off the track.

"She's one of the best team players I've ever had the privilege to work with," he said.

"Always putting the needs and best interests of the team first, before her own.

"We loved her like a daughter.

Following a touching photo and video montage, an Olympic flag draped over Hoskins' casket was removed and handed to her family.

A rendition of 'Somewhere Over The Rainbow' filled the chapel as attendees got up to place rosemary on the coffin.

A visibly emotional Dennis took each of the couple's children up to do the same.
