What bike should I get? For forests and city mainly So right now I've got a hard tail but I'm not really happy with it. At the moment I'm only riding my bike in the city even though I am planning on riding it in the forest and parks as well. My question is what bike to get. Should I get an enduro bike, downhill or whatever is best for the above mentioned categories.
That being said, I don't have any mountain biking experience but I know how to ride it well.

Or should I keep my bike which I am using right now?

I hope you guys can help me and thank you already so much for your help!

Have you got a suggestion for a new bike? price range up to 700 Dollar/Pound/Euro please
I don't think there is anyone who can tell you what you will like.  

It's all about the test ride.
If there is any way you can rent/borrow or test ride at the bike shop lots of different bikes to get a feel for the differences in the different kinds of bikes it's the best way to know what you want/need.

It's all about trade offs and the best way to know is to get out and try things. Build up your knowledge of how different bikes feel so you can make an informed decision.

Sometimes you can get something you really like by going to wider or narrower tires and a different seat.
