There are four signs banning cycles, motor cycles/scooters etc on the promenade just as you enter the prom plus more at the end near the Mutlu, so yes they are all banned and people have been stopped and fined if ignoring the signs. It got so dangerous along the prom, with cyclists, electric scooters, etc going up and down, it was an accident waiting to happen. There is a road running along the back of all the restaurants along the prom which gives access to all the restaurants or beach.
