Need Reccomendations
 

Hi guys, I'm new here, not sure if this is the right forum to post this...

I own an old BMX bike that gets me around, but some of you might know that a simple hill can sometimes be a task for BMX bikes, and they are not ideal for long rides of workouts. I would like to purchase a mountain bike for exercising purposes and also to get me where i need to go. If anyone can throw some models at me, I'm looking to buy something around $300 (canadian). thanks
