    Matte Black 6 – 4130 Core-Line

    Beautiful Bike

    Bought the Core-Line 4130 for my son to take to college. He loves everything about this bike. All parts of the purchase experience were great. Just arrived in L.A. from Portland with his bike in the back of the SUV. Ready to roll.


    What more can I say.. awesome bikes from an awesome brand!

    Fun ride!

    An absolute superb bike! Very happy with my purchase!
    I used to own a 'Charge Plug 0' and the State is, without a doubt, a better ride!
    If you were looking for a great, under $500, single speed - your search has ended! ENJOY!

    Love this bike

    Love the minimalism. The bike is so light, easy to maintain, and has everything you want in a single speed/ fixed gear. Definitely happy about this purchase!

    Love this Bike!

    Bought this to get back into cycling after a very long layoff. Rides like a dream, very fast and able to handle the streets of NYC. Set it up SS to start until I get my legs back underneath me, but nice to have the option for an easy switch to FG. Highly recommend to anyone interested.

    Matte 6 almost all black

    My over all experience was ok. I bought the bike after a bunch of research that showed good and bad experiences with state bicycle. I thought free shipping and returns that’s cool till I realized I would pay the return shipping. I received the bike in good time and opened it to find I needed to have a bike shop assemble the bike to have the warranty active. Not so fun I live in the middle of nowhere and the one bike shop has a two week wait. So I built it my self, didn’t seem scary for an experienced acft mechanic. Got the packaging open and the spokes were all chipped up so I called and was told I would have to mail the whole thing back. At this point I said forget it I’ll keep the bike buy some paint and have learned my lesson.

    Great bike! This is my second State bicycle and I could not be happier.

    Beautiful bike

    I've had the bike for about two weeks now, and it's been amazing. It's nice and light, super smooth, and it's been a blast to ride around.
