I'm looking to get a beginner mountain bike. I will be using it for trails and street. I've been looking at bikes for two weeks and I have two bikes that I'm considering so far. The trek 3900 and the raleigh mojave 4.0. The trek is for sale without disc brakes and the mojave does have disc brakes. Feel free to recommend any additional bikes. I am not looking for a women specific bike necessarily because I am tall (5'10") and have long arms. I am also trying to stay around or below $500. Any comments, suggestions, or advice?
