Mobile speed cameras are to be used to catch speeding cyclists along Bournemouth seafront.
Riders caught travelling above the 10mph speed limit will be given safety advice.
The scheme has been introduced by Bournemouth Borough Council in partnership with police following complaints from pedestrians.
Council rangers armed with cameras will patrol the promenade over four days in June.
Charmaine Andrews, leisure services officer at the council, said: "We have had reports of people speeding on bikes along the seafront and what we don't want to see is a cyclist racing along the promenade accidentally knocking down a small child that gets in his or her way.
"We do encourage cyclists to use the seafront but we want them to take care in doing so and to watch their speed."
In July and August, cyclists are only allowed to ride on the promenade before 1000 BST and after 1800 BST.
Anyone caught outside of these times faces a fine of up to £1,000.
