A nearby resident who witnessed the aftermath of Monday's accident, which took place just after 8am on the B981, told Times Online, "It's a fast road and has a blind hill.
"I'm upset about not knowing who it is because I wave at a lot of people who go past my house on their way to the cemetery.
"I could see a bike that looked in a bad way."
