The scheme follows complaints from pedestrians walking along the seafront
Mobile cameras used to snare speeding cyclists on Bournemouth seafront stopped 69 people in four days.
Riders were caught out travelling above the 10mph speed limit during the operation and were given safety advice.
The initiative was launched to warn cyclists of the dangers of reaching high speeds during the tourist season.
Bournemouth Borough Council joined forces with Dorset Police as part of the operation, which took place over four days in June.
Council rangers were armed with cameras and patrolled the promenade, however wet weather meant few cyclists were around during two days.
Charmaine Andrews, seafront development officer, said: "We received a large number of positive comments regarding this safety initiative and hope that it has raised awareness amongst cyclists of the dangers of speeding on the seafront, to both themselves and pedestrians.
"We want to encourage cyclists to use the seafront, but we want them to take care in doing so and 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.
