Since I am getting in better shape I have thought about getting my 10 year old son and myself some mountain bicycles. I just need them to be able to have wide enough tires and shift low enough that we can ride some power lines and woods trails.
I don't know a thing about buying a mountain bicycle. Should I just go to Walmart and pick one out? Is there a specific good cheaper brand to look for either new or used? Is there a specific feature I will need to look for that makes for a better bike?
