    Feeling undefeated.

    Josh Tyrrell on Youtube became my hero and I've got interested in Undefeated II. And I decided to buy it because it comes with SRAM Omnium in the middle of its beautiful body. Chat & e-mail with State Bicycle Support Team was quick and clear so I had no worry placing order from distant country. The bike is shining, finished with great craftsmanship. It easily gain high speed but also comfortable cruising with low speed for daily use. While I'm few meters away from this bike, I see some people taking photo of it. Beauty of this bike is beyond standard in my city. Fixed gear bike may not be an answer for everyone. It takes time to get use to non-free-wheel cycling style -- you have to keep moving your leg. But I now understand it is an unlimited joy for those who seek for challenge and adventure. And if someone ask me about fixed gear recommendation, my answer will be always "Undefeated II".

    Undefeated II

    I've been riding this bike for the past 4 weeks or so, and I love it. The moment I picked it up out of the box I couldn't believe how light it was. The bike I had before this was the Trooper 3.0, so it's a big step up. From riding it, it's very maneuverable. And honestly every time I look at the paint job I feel like I'm going faster because it's just cool. All the stock components that come with the bike I'm very pleased with. I've mostly been riding on the streets, and the bike can sure take a beating. I've gone over some pretty bad pot holes, but the carbon fork can take it as well as the Essor wheels.

    In Love

    This bicycle is absolutely beautiful. The components are top notch and, upgrading from core-line, the differences in performance are striking. Basically perfect stock out of the box. The tires will need to be swapped with better ones--but that's to be expected, and it depends on how/where you ride. The wheels needed truing out of the box but that's not a huge surprise either and a relatively inexpensive fix. The bike is FAST and light. Paint job is extraordinary in person.

    Love my Undefeated II

    This bike is amazing! It's a smooth ride right out of the box. Not a fan of the handle bars that came with it. Every else is perfect and I can't stop riding it! Would recommend this bike to anyone looking for a new bike!

    Made me stop looking at other bikes...

    First of all, this is the only bike I've never had a flat with. I bought it on Cyber Monday 2016, so it's been a little over 6 months and I'd say around 1200 miles of construction infested Miami potholes, I'm still waiting on my first flat. Second, this bike looks sick. I find myself looking at it just to feel better sometimes. Very few days go by when I'm not complimented on its design. And lastly, but most importantly, it rides like a champ. Fast and quiet. It's built quite strong and yet it's weight is a bit over 15lbs. I'm around 210lbs, but this bike has no problem supporting me through the air. The discounted price I paid for this bike on Cyber Monday shaped this transaction into one of the sweetest deals I've had on any bike.

    Buying Experience

    If you look up my original order, you will see that I did not get the bike I wanted. It took State Bicycle some time to figure all this out, and finally did make good by offering me a comparable discount on the Undefeated II.

    The reason I ride a lot now

    The Undefeated II is the best fixed gear bike I have ever ridden. I push myself harder than I ever have on this beautiful bicycle.
