I've started biking more and more thanks to my crazy wife and I'm considering getting a better bike. Right now I use some $150 mongoose mountain bike for everything (on and off road). It's okay, but it has it's problems and I'd like to get something better. Most of our riding is done on roads and streets but we still ride trails every now and again. I'd say its like 80% road / 20% trails. I'd like to make my rides as comfortable and efficient as possible. I'm thinking a hybrid bike might be what I want, but I'm also considering a road bike and then just using the mountain bike for trails. I know next to nothing about who makes the good stuff and what does what. Budget-wise I don't want to go too crazy because it's just a recreational thing and I'll be buying a second new bike for her as well. $400-$500 is where I'd like to stay if possible. So please educate me bikers.
