      Beautiful Looking Bike!

      This bike looks, great, and I've been riding it as much as I can since I got it built. The slick paint job gets lots of compliments. Looks good while riding, and when it's sitting at home, which is a huge plus for my partner who isn't as into bikes as myself. I look forward to using this as my commuter for years to come, and am planning on upgrading the saddle, tires, and pedals later myself. Fast shipping too.
      Only downside is that it had a chip in the left-side chain-stay paint out of the box, but it's not super noticeable and probably happened during shipping. Front wheel was very untrue but your bike shop can fix that for you quickly.

      12/10 would recommend

      I'm thoroughly pleased with the new Core-Line I purchased! Also I was shocked at how fast it arrived. Never had an issue with the time of shipment. Definitely would recommend State Bicycle to everyone.

      Smooth quiet ride

      This is my first fixed gear bike, and I love it. I've only had it a couple of weeks and just started tinkering and getting it really comfortable. I bought the bike completely stock and nothing has been a disappointment. Feels pretty slick getting around town on this bike

      Rutherford SS

      Received the Rutherford SS - great packaging and fast shipping!
      Went together easily, everything flawlessly !!
      Paint was perfect and bike was lighter than expected - now makes me want a SS Cross bike from State even More!

      My 1st

      This is my 1s bike from State Bicycle and I am IN LOVE WITH IT!!!
      It’s beautiful.
      Took sometime to adjust, to get it right to my height and center but now it’s perfect.
      I get compliments all the time.
      And my favorite feature: it weights nothing!!!!
      My old bike was too heavy which is why I purchased a new one.

      excellent bike, great feel

      Had some chips in the paint job upon arrival (not in a spot related to shipping,I don't think). Love the feel, the size is perfect for me. Rode 20 miles through the city my first day with it, and have no regrets.

      Great Bike and rides clean

      This bike is amazing, for not riding fixed in a few years it's nice to hop back on one. The only thing I'd recommend is taking off the skinwalls / gumwalls and throwing on a pair of thickslicks, better for skidding and last much longer. Beautifully lightweight and handles well.

      Instant Classic

      As good as the pictures make the color combo on this model look, they don't do it justice. It pops. Everything seems to be of great quality for the price, light but solid.

      Great bike

      Amazing frame, quality build, super light 4130 chromoly even for a large with water, gopro and lights. Lovely paint job, bar wrapping. The only flaw is 23 skin/gumwall tires, while they look beautiful, the sidewalls are very supple and don't take semi-tight turns well. And known fact that 23's puncture with ease. I'd recommend throwing a pair of thickslick tires on.
      Other than that no complaints!!!
      Amazing bike!!!

      Absolutely amazing.

      The bike has been fantastic. It was easy to build and a good learning experience. Tried both the single speed hub and fixed gear. Decided on straps and staying fixed, rides like a dream.
      Would certainly recommend to anyone looking for a bike.
