      4130 Rock and Roll....

      Bike went together flawlessly! Customer was super stoked to get on and Ride away.

      Just what I wanted!

      Just picked it up from the shop after getting built. Beautiful finishing and ride. Perfect for tooling around in NYC. Rides smooth and fast!


      This bike is such an upgrade from my Frankenstein bike that I put together over the past few months. I can’t express enough how smooth the ride is and how much more enjoyable riding a fixed gear is in the early months of spring. Thank you for the folks at state bicycle for making a dream come true.
      -a fellow cyclist.

      Great bones! But packing and quality of pre-assembly could be much improved.

      After getting the bike together with some professional help, this is a really great bike so far. Love the look, the geometry, and the ride. The frame is quite sturdy, even during aggressive riding. However, the bike arrived with fairly sloppy, sub-par packaging, complete with several nicks and scratches on various parts of the bike (nothing major). The front wheel was so out-of-true that I had to use my limited knowledge (and cheap spoke wrench) to correct it enough to even ride it to the shop to get them to fix it up for me. Had the packaging and pre-assembly (specifically of the wheels...I mean, some of the spokes were COMPLETELY loose...) been better, this would be a 5-star review. All said, a great bike for the money. But you might need to deal with a few scratches, and will need to pay a pro to get the assembly up-to-par.

      Awesome Bike

      I had ordered this bike and waited in anticipation for it to get here! As soon as I had received it, I had Sonoran Cycles in Yuma, AZ assemble it for me. All of the parts were there. I took it out for a test ride to make sure the seat and bars were adjusted properly. I purchased the Mate Black 6 - 4130 Core-line bicycle and I don’t regret that decision at all! Great frame, awesome frame, and has a great ride. I have recently added new bars and saddle and have changed the pedals to give myself straps. I highly recommend purchasing this bike if you are at a crossroads as to what to get. Seriously, best decision I could’ve made was get into cycling and the next best decision was to buy this bicycle. I couldn’t be anymore happy with their quality and fast ship time. 🙌🙌🙌

      Super happy with my bike!

      I have had my bike for a little bit now and all I can say is it has been the biggest game changer in my life! It is my first fixed gear bicycle and it does not disappoint! I am extremely grateful for the high quality and attention to detail that State gives to the bicycle overall. From the quality to the Matte Black finish, I am absolutely in love with it! One thing I would recommend is investing in sealant for your tire tubes and if you live in an area that has those sticker thorns, maybe invest in some really good quality tires. Other than that though, a phenomenal bike and I highly recommend! 👌

      Overall really good

      Some scratches on the bike. But overal really good


      Product is good customer very happy. But you could improve on the delivery time. 7 days is to long


      Well built and easy to put together. Rides smoothly and is true to size

      Love the bike!

      Arrived quickly, took it to a great local shop for the build and I've been riding it nearly every day. No complaints!
