advice please
so is there a website or somewhere i can go to get some info on bikes. I would like to know the benifiets of a road bike over a mountian bike and hybrid bike and what on the road bike is better than hybrids and mnt bikes and the other way around too. I got this friend that wants a bike but doesn't know what kind he wants. He doesn't know a thing about bikes and said he guess a mnt bike will be fine but he'll just be going on light trails and roads/sidewalks and riding to work on it sometimes too. He loves to go fast in cars so he'll prolly like to on a bike too. So I suggested a road bike but he thinks he wouldn't like the handlebars but he's never tried them, he's only familiar with the mnt bike handlebars so I was thinking maybe get him a road bike and change the handlebars and maybe put 700x28 or thicker tires on? maybe he'd like that.
