The family of a cyclist tragically killed in a crash while on a fund-raising bike ride have paid tribute to the father of three who 'will always be so dearly loved.'

Christian Smith's relatives were speaking after he died following the crash with a blue Peugeot 206 at 4am on the A2990 Old Thanet Way on Saturday.

Now a JustGiving appeal set up by Christian - who would have celebrated his 39th birthday today - has already raised more than £68,000.

Mr Smith was raising cash for mental health charity Mind, after suffering from mental illness himself.

In a statement released today the family said: "Even in the depths of our grief we are moved beyond belief at the outpouring of love and support that has been shown by so many, especially as most didn't even know Christian.

"His story has touched cyclists and mental health sufferers, families and individuals across the world.

"He is a husband, father, son, brother, uncle, cousin and friend who will always be so dearly loved and remembered.

"We are all so proud of everything that he has achieved.

"His death was tragic and we pray that no one else has to suffer similar sorrow and heartache.

"Christian had a great sense of humour, he loved life, his family and was a dedicated cyclist."

Tributes have poured into the JustGiving site, which has seen more than 5,000 donations.
