I came from South Africa and I will tell you there are real mountains for mountain biking. Not only is it one of the most beautiful countries it has everything the US have and more. You don't have to worry about the wild animals. They are located in nature reserves and private hunting farms. There are numerous biking routs and if you stay with an organized setup. Just don't advertise that you are a tourist. Thugs will rob you from you cell phone and camera. I arrange safaris to the northen part of South Africa where you will find more wild life. Reply if you want to do that too
