The scheme is believed to be the first of its kind at a NSW hospital.
People who want the convenience, fun or fitness of a bike ride can indulge without having to buy a bike and helmet.
The new "swipe and ride" solar-powered, credit card-enabled bike station provides an opportunity for staff and the community to more easily increase their physical activity and enjoy all the other benefits of cycling.
Northern Sydney Local Health District (NSLHD) health promotion director Paul Klarenaar said the three-month trial would see bikes available for hire 24 hours a day.
"Using the bikes will be easy," Mr Klarenaar said.
"Just collect a free loan helmet and lock at the RNSH information desk and go to the bike station at the front corner of the adjacent Kolling building forecourt.
"Swipe your credit card, choose your rental period and cycle around the sights of the campus, St Leonards or beyond.
Rates are subsidised by Health Promotion during the three month trial period and start at $2 per hour, up to $10 for 24 hours.
Just remember it's a trial so if you want it to stay keep using it.
Thanks to everyone who attended the launch on October 20.
