Keyes originally joined Bradford from London at the start of 2016.
The scrum-half made four appearances last season
Peltier joined the Bulls from Keighley at the end of last year.
The new owners have stated that they have 26 players signed up.
Leon Pryce is staying with Bradford and has been appointed captain.
Glad to have put pen to paper and signed for the new Bradford club look forward to focusing on having a massive year and proving my value
