Emergency services were called to the corner of Bathurst Road and Nunns Avenue at around 6pm on Wednesday night following a collision between a Holden and a bicycle.

Witnesses say the man was riding the bicycle south bound on a footpath parallel to Bathurst Road when he rode on to the road and was hit by the vehicle.

The driver of the vehicle was a 59-year-old male from Orange.

The bicycle rider was treated on the scene before being taken to Orange Hospital.

He sustained a number of abrasions and a laceration that required stitches as well as a possible bleed on the brain.

Police couldn't confirm if the injured 38-year-old was wearing a helmet.

Police say investigations into the accident are continuing, with the injured bicycle rider yet to be questioned following the accident. No charges have been laid.
