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).
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.
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.
Customer Reviews
This started out as a silly idea. 120mm rear spacing? That’s track wheel spacing. Not really a coaster guy. Naturally, i buy the frameset (which came with a mangled headset. State replaced it quickly and free-ly. A+)
Anyway… in the meantime i picked up a 135mm mtb disc fixed wheel. So naturally the first thing i did was space it to 135. Warranty = void. But the next step is a buddy adding disc tabs to it, so the warranty isn’t high up on my priority list). The idea was a SS/fixed 27.5” fairly fat tire bike. The 2.2 race kings fit great.
But then i got to thinking. You know what else clears? 29 x 2.1” tires… so that’s how it is now. Fixed gear. No brakes. 29”. Honestly? This doesn’t really get a ton of miles. The odd light duty trail rip. A short ride the kids to the gas station. And you know what? It’s super fun like this. It feels like a giant monocog. All things considered, it isn’t even really all that heavy. Just a cheap, simple, hell of a good time.
I purchased this frames to create my own version of the State Klunker. I’ve been slowly building it up as a 26” wheel setup. Thinking I like the geometry with the smaller 26” wheels. Anyway I like the freedom of using the frame as a clean slate. At the present I’m building it as a SS. Lots of other potential.
Took the 420 to another level
2 smoke station
One in the stem cap
One in the grip plug
Made this for my Token Brother
I recently purchased the klunker frame.With the fast shipping I received it in a few days. The frame looks great and very well built. I’m not building a klunker but a cruiser. This frame I’ll have for a very long time. You can tell it will last. The price is nice you get a lot of quality for the money.
A excellent frame to build on. Some reasons why as follows. First it has the timeless style of the old classic Schwinn of 1938 how ever this frame is far superior in strength and much more stiff which transfers more acceleration and energy to the wheels. Second this frame sports the crank bracket with a bit of a drop that gives a lower center of gravity which give the bike excellent cornering over currant modern production bikes but still has good ground clearance do to accepting the taller27.5 wheels over the old Schwinn limited to the 26”. Third the welds are nice and the paint quality on my four builds are excellent also. The fourth reason is the frame and fork set red illy accepts a set of 2.50 width tires with no clearance issues as can be seen on this example here. Running the big 250’s gives the build not only a smoother ride in the rough but protects the wheels and keeps them true. Shown here in the photo’s is one example. So if your lookin to build a head turning classic hot rod old style very capable do all ride this offered frame set is hands down a deal at 199 plus tax and shipping. However don’t forget the bottle opener on your build if you choose to do so as that is the most important part of the Klunker bike.
Definitely cheaper and easier to attain than an old Schwinn
Took the Free n Easy n twisted it
Can’t say enough good things about State Bicycle. Purchased a Klunker frame in gloss black. Frame showed up and I was nervous from the get go because the box looked a little beaten up. Sure enough, upon inspection of the frame, the chain stay had some scratches that went all the way through the paint. It appeared as though the fork, which had been zip tied to the side of the frame, had rubbed against the chainstay during shipping. Took a few pics and reached out to SBC. Their customer service team could not have been more friendly or understanding or HELPFUL! Super easy to work with. Sending back the damaged frame was a snap and I’ve got a new frame headed my way now. I would not hesitate to recommend State Bicycle Company when you are in the market for a quality, affordable bike from an outstanding company.
Shown here are some very healthy 250 width tires. Don’t be afraid to run them as they will tame the terrain and keep your wheels true. I run 250’s on all four of my State Klunker builds with plenty of room for them even if you tweak a wheel while getting a bit happy showing off to the ladies on your next outing. This frame set is a fantastic deal , light strong with some good geometry. If you plan to build a custom suit to fit then this is where you start. If you don’t ,then your missing out. Been riding Klunker bikes since 1969 in Marin County . I wish I had had this example shown here at the get go with the 27.5 wheels. I have moved away from Marin but not the Bike that put Marin on the map.
Frame and fork are of excellent quality only issue is came in scratched in several locations
