I live in Florida so it is fairly flat..

I'd be riding this bike on the road, grass, and sometimes dirt. Probably not many trails

I'm stuck between a Trek MTB or Hybrid. I don't really like those hybrids where you are sitting almost straight up at all (makes me feel like an granny haha). I'd like to keep it under 400.

Which bikes do you think would be good for my situation??? I liked the 4300, and the su100 looks very cool.

Thanks Alot!!
