He was a father of three and grandfather of six, and had been participating in the event for the 24th time, making his first ride in 1999 after a quadruple heart bypass.
Cooper was one of thousands of riders taking part in the 54-mile (86.9km) route from London to Brighton while raising funds for the British Heart Foundation (BHF).
His daughter described him as an "amazing" person who would do anything for anyone.
Surrey Police are investigating the circumstances surrounding his death and are appealing for witnesses.
