We are trying to find a solution to the problem of motorcyclists abusing public parks by putting a barrier that will stop them entering whist allowing disabled people, double buggies & scooters access. I thought possibly a RADAR locking system incorporated into a gate. Has anyone come across this or have you a better solution than an "A" frame entrance barrier?
