      My favorite Ride

      There's nothing more i love than riding in my car to go from point A to B... except when B is a few miles away and i can take this bike for a ride. Worth every penny

      Good bike, fast shipping.

      Good bike so far. Seems to be well built with decent components. Shipped quick. Arrived a week after the order was placed. Packaging was ok. Arrived without any damage. Wheels were true out of the box. Frame paint finish is good. I like the plain frame without a a bunch of big logos. Very clean look. I asked for a black seat and black grips instead of the brown seat and white grips when I placed my order, but that didn't happen. No big deal... the stock seat is very cheap and I knew I would need to replace it immediately. No surprise there. I replaced the white grips with black Oury grips. And I also swapped out the stock tires for 28c Schwalbe Marathon Plus tires that smoothed out the ride a bit. One small issue... I opted for the riser handle bars instead of the standard bullhorns and the front brake cable was a too short with this set-up. There was hardly any slack and both ends were pulling at a tight angles out of the cable adjusters. I'm only running the front brake so I used the the rear brake cable and cut it down to proper length for the front brake. A little more attention could be paid towards these areas. Someone who's not experienced working on bikes might not have solved the issue on their own. Overall, good bike for the price. Happy with the purchase.


      Bernard – 4130 Core-Line

      Great bike

      Just started riding again and needed a short commuter bike so the Bernard 4130 Core-Line is perfect for that. Really looking forward to getting more time on it as the weather warms up and it is a great looking bike as well.

      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!

      200 Miles and counting...

      I have 200 miles on my State and I am loving it. I did an unboxing video you can check out here. https://youtu.be/Qvg8tmQXsQw

      Bernard 4130

      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.
