      My first Steel Bike

      I gotta say you guys got it right with the freewheel side. I can pedal. The 45 /14 fixie is another story. I am buying an 18 for that side so I can ride the fixie over hill and dale! I love the black bike and I love the weight of it on my commute to and from work each day! Thanks so much!

      Sad to see the 4130 disappearing

      Tubes aren't the best but the frame geometry is perfect for my short girlfriend, whom has already put 10 miles on it with no complaints.

      Fantastic bike

      I've owned far more expensive single speed bikes that aren't as good as this one. And it looks fantastic. People keep asking me about it.

      Great product, State Bicycle Co.

      Cool Ride

      I got this bike because of its aesthetic appeal after searching thru all the single speed reviews. I like the simple appeal, devoid of neon and such. The best surprise was picking up the bike - it was very light. The gear ratio makes for real fast going on flats and only somewhat challenging hill climbs (I live in a flat area so my hills don't go on forever). So far, although not as comfortable as my hybrid bike, I still use it to commute over Dallas' rough roads because of how zippy and responsive it is. Exactly what I was looking for.

      Exactly what I hoped it would be

      I have loved riding this bike! It is so smooth, so simple, and enjoyable to ride. I would definitely recommend this bike.

      Great Bike!

      I use this bike for commuting to school. It looks great, rides smooth, and has a decent price. Only this I would upgrade would be the tires, other than that very satisfied!

      Great bike terrible customer service

      Started horrible got better after a local Colorado bike shop helped me after you guys wouldn't listen to me. Terrible customer service but great product. Won't be buying from you again due to your customer service which is a shame because the bike is working out well after the local bike shop got it in order.
