Not much difference if you go to the components and specs. They appear to be the same components on both bikes but the 2.0 has some parts anodized. If that's worth $20 to you, choose the more expensive model. They do have the cohones to list an approximate weight of 25 pounds which many of the larger companies do not , leaving you in the dark when it comes to the bike weight. Not bad weight for a sub $300 bike. And, they have three frame sizes to choose from. So many entry level bikes are "one size fits all" which is pure bull.
