Alistair Speed, 49, from Glenrothes, died at the scene of the accident on the A91 between Strathmiglo and Gateside villages in Fife at around 11.30am last Thursday.
Mr Speed's family said they are heartbroken by his death. "He had a heart of gold and his passing has left a huge void that will never be filled," a statement said.
"He had been a keen cycle racer since the age of 12 and was a long-standing member of the Fife Century Road Club.
"His partner Sue, parents Margaret and Archie, sister Mhairi and her family are deeply devastated by their loss."
Mr Speed followed his father Archie into the sport of cycling and was passionate about it both as a competitor and as an official at events, the statement said.
"The interest shown by his young nephew Gavin in cycle racing in recent years provided him with an added focus and enjoyment. They trained regularly and would often be seen together warming up at time-trial events."
The family said they have been deeply touched by messages of condolence from cyclists throughout Scotland.
Police have renewed an appeal for witnesses to the accident to call them on 101 or Crimestoppers anonymously on 0800 555 111.
