The pair were reported riding off-road bikes on the roads and on woodland owned by the Forestry Commission in the Forest of Dean.
They were acting in an anti-social manner, causing concern among residents in villages surrounding Coleford on Saturday 17 July.
We are now appealing for the public to help us identify them.
Officers in the Forest area have noticed an increase in incidents involving bikes where members of the public are being put at risk.
PC Georgianna Jayne said: “We have a good relationship with the rangers at Forestry England and are working together to reduce crime and anti-social behaviour which can so easily spoil the enjoyment of many of the local people and tourists who visit the forest area.
“We would continue to ask members of the public to help us by reporting incidents and, if possible, supplying photographic evidence."
