According to the RAGBRAI website, he suffered from a medical issue and not from a traumatic injury. He was taken to a hospital in Emmetsburg where he later passed away.
The last time someone died during the bike event was in 2010 when a cyclist collided with another rider. Within the 42 years RAGBRAI has taken place, 29 people have died during the event.
