I am Turkish, if you're going to cycling through major cities like Ankara, Izmir, etc you'll need to watch the hell out for car drivers there, cycling is literally almost unknown down there, lots of reckless driving going on, but once you get nearer towards the border of Syria and out of central Turkey it should gradually come a bit more relaxed and more enjoyable, but if you're going at this time of year, your rides will have to be in the early mornings/evenings because you will simply bake in the heat during the day in Turkey
