An off-road bike was seized by police in the Maesgeirchen area of Bangor last weekend.
Police had been informed that a man had been riding in a residential area causing a nuisance and danger to members of the community.
North Wales Police said: “It is illegal to ride off-road bikes on public footpaths, and bridleways, common or council land such as beaches and parks.
“Previous social media posts regarding this subject have received comments highlighting a lack of suitable local facilities
“This is not a reasonable excuse for illegal and anti-social riding on public highways, that endangers the local community, as well as the riders themselves.
“Private land can be utilised only if the landowner has given permission.
“Gwynedd North policing team will continue to tackle off-road biking on public highways.
“If you have any concerns regarding off-road bikes and their anti-social use please contact us via our live webchat online, or on 101 or anonymously via CrimeStoppers on 0800 555 111.”
