Undefeated II - Black & White Edition (Retired)
Race Ready - Out The Box.

Straight out of the box - the Undefeated II is a race ready, beast of a machine. Building upon the original Undefeated's winning pedigree, The Undefeated II comes stock premium SRAM Omnium Cranks, Michelin Tires and Ritchey Components stock while featuring new and lighter rounded 7005 Aluminum Double Butted Tubes.

These new features make The Undefeated II the perfect tool for mastering fixed-gear crits. The Essor USA Bolt 31 wheelset is an added bonus - being both lightweight enough to race (1736 g) while still being durable to take a beating on the street.

    Have only put about 100 miles on this unit and the rig performs like nothing I’ve ever rode before. The apparatus has lightning response and is incredibly stiff. Even with the stiffness it remains comfortable on city streets and bumpy roads. Build quality is outstanding and I’ve had zero issues. This bad to the bone rocket ship will drop her panties and soil his briefs a real win win. Stoked to keep riding

    It's a great bike

    The bike is good quality and it's everything i expected

    I love this bike!

    I am so happy with this bike! I am a single speed guy 100%. I commute and ride for pleasure around Minneapolis and St. Paul every day the weather permits. I ordered the vision flat/bullhorn bars with the build and put a comfy saddle, a freewheel, and clipless pedals on the bike, and it's nearly at optimal efficiency and utility. I will upgrade the tires and maybe the brakes next season. I have been out riding with some friends on geared bikes and I am keeping pace on the flats and SMOKING them on the hills--such a good climber! I love the simplicity of the bike. Thank you so much for making such a sweet build! I'd be interested in buying an even lighter build, maybe all carbon fiber, in a few years, if State Bike Co. can put one together for me ;)

    Fast and quiet

    This bike knows how to move. If you want to go faster, it’ll laugh and say, “you call this fast” It’s also a known fact that a quiet bake is a fast bike and this one holds true to that. Silently gliding along the road is a dream. This bike is worth it.

    The best ride and best service

    Love the bike in every aspect. The customer service was impeccable.


    Had a frame shipped to Canadia. Was very stoked to receive it, upon unboxing, there was a dent in the top tube, MFG defect FOR SURE. The box was totally intact and showed no signs of damage. Either way, got an email going with the Shipping and CS team and they are sending a replacement frame ASAP. SERIOUSLY! BEST CUSTOMER SERVICE EVER. V stoked to get on this bike and tear it up!!

    SBC 4 LYFE

    Awesome bicycle and customer support.

    I think the bicycle Undefeated lives up to it's name. The customer service was really helpful.

    One bad mamma jamma!

    I bought the undefeated as a recommendation from a couple of coworkers that ride state bicycles. For the price you cannot beat the components that comes with this bike. I’ve only ridden it for about 20 miles or so but first impressions are great. Fit and finish is top notch and for my first fixed gear I’m very impress with the bike.

    Can’t go wrong.

    Purchased two bikes, the contender two and the undefeated two. Simple fact is you make a great product, at a fair price. Customer service is excellent, the way things should be.
