Concerns have been raised about the nuisance caused by off-road bikes and quad bikes on an estate in the south of Bradford.
Police have pledged to reduce the anti-social use of such bikes on Broadstone Way, in Holme Wood.
One tactic they will use will be to serve warning letters to anyone deemed to be causing a nuisance to the public.
Police warned that vehicles could also be seized under powers available to officers.
Meanwhile, in Bierley, officers say they are keen to deal with and reduce vehicles speeding at all times of the day on Burnham Avenue.
