FAQ

Rider-owned in Phoenix, AZ since 2009. 5-year frame warranty on steel, aluminum & titanium · most in-stock bikes ship in 1 business day · 4.8/5 from 16,000+ reviews.

How does my bike show up, and do I need a shop?

That depends on how you order it:

  • With Pro-Build (select models: $79.99, or $129.99 on Carbon Road). Our mechanics in Phoenix face the frame, set up and bleed the hydraulic brakes, index the drivetrain, cut the steerer to our stock length and torque-check everything before it goes in the box. That's the shop work that usually runs $150–$300 locally. You bolt on the bars, seatpost, front wheel and pedals, set your hoods and wrap your tape: about 20–30 minutes with a hex set and a torque wrench. Pro-Build adds a 1–2 week build queue.
  • Without Pro-Build. Your bike ships mostly assembled, but it needs a full assembly and tune by a professional mechanic before it's ride-ready. Carbon, titanium and AXS builds that skip Pro-Build arrive unassembled with an uncut steerer, so your shop can build them to your exact fit.

Either way, a professional build is safer, rides better, and unlocks our better warranty tier (see below).

How Pro-Build works · Find a shop near you

What does the warranty cover?

Every State bike comes with our Standard Limited Warranty against manufacturing defects for the original owner. No registration required.

  • Steel, aluminum & titanium frames and forks: 5 years
  • Carbon frames and forks: 1 year (2 years with ProBuild Advantage)
  • Non-consumable parts (cranks, wheels, hubs, bars, stem, seatpost, pedals): 1 year

Not covered: wear items (tires, tubes, chains, brake pads, grips, bar tape, saddles, spokes, paint), rust on RAW finishes, crash damage, and labor or shipping costs. Full warranty details

What is ProBuild Advantage, and how do I get it?

It's our "you did it right" warranty tier for bikes that were professionally assembled and registered within 30 days of delivery. You get everything in the Standard warranty, plus:

  • 2 years on carbon frames and forks, instead of 1
  • Priority claim review: ProBuild claims go to the front of the line
  • Faster help with shifting or braking issues, without the "did you tighten that bolt?" back-and-forth
  • Shipping perks on approved warranty replacement parts
  • Discounted pricing on a replacement frame or bike for up to 5 years from delivery, if a crash wins

To activate it: add Pro-Build when you order, or have a local shop assemble your bike and keep the receipt. Then register your bike within 30 days of delivery with your serial number (engraved under the bottom bracket shell) and proof of assembly. If you ordered Pro-Build, our mechanics already did the build. You just register.

When will my bike ship?

Most in-stock bikes ship within 1 business day, and you'll get tracking as soon as yours is on its way. Adding Pro-Build puts your bike in our build queue for 1–2 weeks before it ships. Shipping is calculated at checkout from your location and the size of your order, and bikes go out by UPS or FedEx Ground.

Outside the U.S.? We ship worldwide, and duties and taxes are paid at checkout, so nothing is due on delivery. Shipping policy

What if it's not right? Returns & exchanges

You have 30 days from delivery to request a return or exchange. Bikes need to be unused, in like-new condition and in their original packaging.

  • Refunds: a return label fee is deducted ($45 for complete bikes), and original shipping isn't refundable.
  • Exchanges: issued as store credit. The return label fee applies here too.
  • Package Protection Plan (add it at checkout): covers loss and damage in transit, removes return label fees and deductions, and extends the window for exchanges and store credit to 60 days. Refunds stay at 30 days.

Pro-Build and other service work can't be refunded once it's done. Final sale, clearance and limited-run items can't be returned, and neither can international orders.

Start a return · Full return policy

Can I pay over time, or use HSA/FSA funds?

Yes. Financing with Bread Pay splits your bike into monthly payments, and you can pay it off early with no penalty (subject to credit approval). You may also be able to use pre-tax HSA/FSA dollars through Truemed. A short intake at checkout checks your eligibility, which depends on your plan. HSA/FSA guide

Which size do I need?

Geometry charts, size guides and full build specs for every model are on our Size Charts & Specs page. Between sizes, or running a tall stack or long stem? Get in touch before you order. Pro-Build cuts the steerer to our stock length, and that can't be undone.

Can I see one in person or get it built locally?

Use our dealer & shop locator to find a shop near you for a look in person, assembly or a tune-up.

Something arrived damaged or missing?

Email info@statebicycle.com within 30 days of delivery with your order number and photos of the item, the box damage and the shipping label, and our team will take care of you. If a part has failed, submit a warranty claim. You can also reach us at 1-855-55-STATE or through our contact page.

Perfect for gravel build

Built up with State 6061 wheelset, 32c gravel tires and compact drop bars. Just finished 334 mile Great Allegheny Passage and C&O Canal trail from Pittsburgh to DC. Perfect bike frame and setup for the trip. Comfortable ride, relatively light setup, no issues. Plenty of braze-ons if I wanted to add even more accessories for the next trip. Only issue was that the rear dropout was slightly bent when I received the frame. State told me they would send out a new frame same day to replace it but I was able to adjust it so didn't need to take them up on the offer. This is the fourth or fifth time I've ordered something from State and the customer service has always been great.

45c tires fit perfect in the front but rear is very close but still will work

Amazing All Road Single Speed

If you’re looking for the perfect single speed frame that won’t break the bank, this it it.

Bought this bike on a whim to build up a Biergarten/Bar bike. So far it’s been nothing but excellent. I bought the frame in 62cm, the frame fits perfectly for my height of 1.95m. The paint job is immaculate and might rival the Black Canyon paint for my personal favorite.

I put a pair of excess cyclocross tires on this for the perfect amount of sendiness & so far has not disappointed. All the trails/off road I’ve taken this bike on have been nothing. The steel frame perfectly glides & absorbs so much rattle on washboard or terribly paved roads. Excited to see what this bike will be capable of with a few overnight basketpacking trips in the future.

State is always coming through with quality steel frames with some of the sickest paint jobs out!

Nice one !

Frame set landed in Australia super fast ! About a week . Shipping cost was way less than half some other brands are asking . Frame was packed well and arrived unmarked ! Finish is top tier . Bikes still a rolling shell so I can’t confirm how it performs but it sure does look good ! Cant wait to rip some skids on Aussie gravel ! Thanks SBC

4130 fixed gear frame

Great frame. I got the 52 size. I am 5/10. Very good fit 👌. The crankset is 46 and the rear is a 16 freewheel. Bottom Bracket is 107mm. The weight is 25 pounds. Great purchase.

Amazing! A squid for 1/3 the price!

Amazing! It's exactly (I mean exactly) like a squid so-ez but 1/3 the price! You can just buy one of these and spray paint it and no one will ever know you ripped off a cool local company! A must buy!

Great frame.. nice welds, beautiful paint.

Bought this frame for my wife and installed a Sturmey Archer wheel set I had laying around. Came out amazing. Frame arrived in quick order and went together very easily. Only complaint is no free stickers or swag. 🙂
