Very much depends on what kind of MTB you're looking for, and what you're ready to spend on it. A high-end XC(cross country) MTB can be around 20-22 lbs(less than 10 kg). For an FS DH MTB (full suspension downhill) around 35 lbs(15 kg) is more to be expected. Here is a bunch of mountain bike frames so you can see the difference in weight ratios....

Remember, it's not about the price tag, it's about the joy and freedom that riding a bike can bring you.
