There are lots to choose from if you want an entry level bike. A few pieces of information are needed for a more informed response. What country are you in, better yet which city? How much are you going to cycle? How much do you want to spend? What's your fitness level? Drop bar or flat bar?

Never heard of KTM bicycles so I can't help you there. Don't rule out Trek or Specialized. They may not have their own factories, in fact most companies don't, but they test the heck out of their products. There is a reason they are part of the big three.

When I think bikes start getting really good is after spending about a $1000.

So with a little more information maybe someone can suggest something.
