    Very happy with my new bike! Customer service was great as well!

    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!

    Good fit, but I had

    Good fit, but I had to true both wheels.

    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.

    Single Speed Bernard 4130

    Very good. My bike shipped and arrived quickly. Front wheel was a bit out of true. I was able to easily assemble but took to a bike shop to assure safe configuration. I’m confused how to activate the warranty as it requires some sort of statement from the bike shop which is awkward to obtain for such little work.

    Come home to me, Bernard!

    Good and I'm glad I came back for another ride.
