On a first read I though "yeah, sure, looks quite dangerous indeed", then I read:
Sylvester H. Roper, inventor of the eponymous steam-powered bicycle, died of a heart attack or subsequent crash during a public speed trial in 1896. It is unknown whether the crash caused the heart attack or vice versa.
This seems to mean "killed in an interesting way". People killed by their inventions in petrol-based transportation seem to be too numerous even for a Wikipedia list: "yeah, people die in cars en masse, that's not really newsworthy."
