Kerry broke his right femur during the crash. Kerry "is stable and... did not lose consciousness," the State Department said in a statement.
He met with the accident while bicycling near Scionzier, France, some 40km south east of the Swiss border.
Paramedics and a physician were on the scene with the Kerry`s motorcade at the time of the accident.
Kerry had travelled to Geneva for negotiations with Iranian diplomats on that country`s nuclear programme. He was cycling about 30 miles from the city, which is closely surrounded by France`s territory.
He was due in Madrid tomorrow for the signing of a defence deal. But it has been confirmed he will call off the remainder of his four-nation trip and return to Boston.
Kerry is known for his love of cycling and often takes his bike with him when he travels.
