Your quote could be a paraphrase of this: Exodus 15:1
"Then sang Moses and the children of Israel this song unto the Lord, and spake, saying, I will sing unto the Lord, for he hath triumphed gloriously: the horse and his rider hath he thrown into the sea."
(KJV)
Considering the language of the time, "... the horse and his rider ..." might have been another biker (in a race?). Rumour has it that the Lord had a 100 Shekels on Moses. No idea what the odds were.
