Bottom line

The State Bicycle Co. single-speed and fixie range may fall under a number of names. Ultimately, many of these bikes share the same frame and components, but are offered in a multitude of colors and themes. Generally, these bikes are seen as great value. They are a cut-price option with mid-range components and a pleasing weight. These aren’t high-end bikes, by any means. A number of customers received bikes with minor damage. But often, riders described a capable, rideable, affordable and presentable, chromoly, single-speed bike.

They look really awesome… options are great… inconsistencies in the paint… packaging was lacking… a sizeable dent… spacing was 5mm off acceptable… I felt like I was getting used goods.

Wheels are where it shines… needs bigger tires… crankset’s fine… you’re gonna need to lighten the gear ratio… handlebars, too narrow… I think State have found the sweet spot as far as the price point goes.

Level 2 expert

The frame is solid, the geometry is to the stable side and handling is easy… Absolutely nothing on this bike would take more than a couple of dollars to replace at any shop, anywhere… If you’ve been wondering about single speed, you would be just plain stupid not to give it a try at this price.

…natural and comfortable from the get go… I liked both the look and feel of the straight blade forks on the Core over the carbon forks on the Contender.
