Firmstrong Bikes is operated by Sixthreezero Enterprises, LLC (doing business as Firmstrongbikeco.com); it’s a private brand, not a public company.
Shoppers ask this a lot, especially when comparing beach cruisers. The brand looks independent, the catalog is broad. If you’ve typed “who owns firmstrong bikes?” into a search bar, this guide gives the answer, shows proof paths, and helps you decide.
Who Owns Firmstrong Bikes — Verified Details
The official site’s privacy notice states that the website is run by Sixthreezero Enterprises, LLC “DBA Firmstrongbikeco.com.” That line identifies the legal operator behind the brand’s storefront and customer service. In plain terms, the Firmstrong bike brand sits inside the Sixthreezero family. You can read that clause on the company’s privacy page and confirm the copyright line naming the same LLC. Clearly.

That’s the answer people came for. Next, a bit more context on why it matters and how to confirm the links.
Why The Ownership Answer Matters
Ownership affects warranty decisions, parts availability, and service timelines. When the same parent operates multiple cruiser labels, it can mean shared supply chains, common component specs, and unified support queues. For riders, that usually translates to easier parts sourcing and consistent policies across similar models.
It also helps you judge reviews. If two labels share leadership and factories, feedback on frame quality or wheel build can carry across models that use the same patterns. That doesn’t erase differences—geometry, tires, gearing, and finish still vary—but it gives you a clearer baseline.
How Firmstrong And Sixthreezero Connect
The connection isn’t rumor; it’s written into the site’s legal pages. The privacy policy explicitly names Sixthreezero Enterprises, LLC as the entity doing business as Firmstrongbikeco.com. The copyright line on the same page repeats the LLC name. That’s the clearest public signal of control over the Firmstrong storefront and customer relationship.
Outside the legal fine print, the market footprint lines up. Both labels sell beach cruisers and casual e-bikes with similar fit-first geometry and easygoing specs. You’ll also see Firmstrong models offered by third-party specialty retailers online, which is normal for a house brand with a dedicated factory run.
Want to cross-check brand control with official records? Two fast routes work well: a basic business-entity lookup for the LLC in California, and a trademark search to see which party controls any registered marks used on packaging and web pages. The steps below walk you through both.
For a direct read, open the brand’s privacy page and look for the operator language that mentions the LLC and the DBA. Here’s an easy link to the privacy notice. If you want to dig into trademark ownership, use the USPTO’s trademark search and look up words and logos used on bikes and product pages.
How To Verify Ownership Yourself (Quick Steps)
You don’t need paid tools to confirm the relationship. Use the two checks below. Each one takes a couple of minutes.
| Step | Where To Check | What You’ll See |
|---|---|---|
| Read The Privacy Notice | Firmstrong’s privacy page | References to “Sixthreezero Enterprises, LLC DBA Firmstrongbikeco.com,” plus a matching copyright line. |
| Confirm Business Entity | California Secretary of State search | Public filings for Sixthreezero Enterprises, LLC, showing status and registered agent. |
| Search Trademarks | USPTO trademark search portal | Any live filings listing an owner for marks used with the Firmstrong label. |
| Cross-Read Contact Info | Firmstrong contact page | Phone, email, and the South El Monte distribution address used for order support. |
| Check Sibling Brand | Sixthreezero site | Active catalog under the same parent category (cruisers and comfort-first e-bikes). |
What The Contact Trail Tells You
The brand lists help@firmstrong.com and a toll-free number for customer care. The contact page also lists a distribution office on Adelia Street in South El Monte, California. Those details match the pattern you’d expect when an LLC runs multiple web storefronts under related bike labels. It puts customer service and shipping under one operational roof.
Where The Bikes Are Designed
Copy on the Firmstrong site points to Hermosa Beach, California as the design home. That city is a cruiser hotspot, and you see that vibe across colorways and bars-up geometry. Final manufacturing is outsourced, which is normal in this price tier, and the bikes ship to customers or dealers from California distribution.
How To Read A Privacy Policy For Ownership Clues
Scroll to the legal sections named “Privacy,” “Terms,” or “Copyright.” Look for any line with “LLC,” “Inc.,” or “DBA.” The “DBA” tag matters because it shows the legal entity operating under a trading name—a common setup when one company manages several brands. When you see an LLC named next to a brand domain, treat that as the operator unless a newer filing says otherwise.
Next, scan for addresses and contact emails. A shared phone number across sibling brands is a giveaway that the same support team handles both. Finally, check the footer year next to the copyright. If the same LLC name appears there and in the privacy text, you’ve got a consistent ownership trail.
What Ownership Doesn’t Tell You
Ownership confirms who stands behind the warranty and the checkout page. It doesn’t tell you everything about ride feel. Wheelbase, bar rise, tire width, and saddle shape play bigger roles there. Two bikes from sibling labels can feel different if one uses a springer fork or a different rim width. So use ownership to anchor trust, then pick based on fit and geometry.
Retailers, Resellers, And What That Means
You’ll run into Firmstrong models on specialty web stores. That doesn’t mean those stores own the brand. It just means they’re authorized to sell select SKUs or parts. The ownership answer still traces back to the entity named in the privacy and copyright lines. Keep that distinction in mind when a reseller page lists its own warranty language or marketing copy.
How This Affects Warranty And Parts
Firmstrong frames carry a stated lifetime warranty with limited coverage on components. Warranty claims usually flow through the dealer where you bought the bike or directly through support. When a parent company runs several labels, parts supply—tubes, tires, chains, chain guards, and saddles—often overlaps. That can make replacements simpler, since you’re not hunting for rare, brand-specific items.
Clear Answers, No Jargon
Firmstrong Is Not A Stand-Alone Company
The website and brand operations are tied to Sixthreezero Enterprises, LLC as shown in the privacy policy. That’s the entity you interact with when you place an order, file a return, or send a warranty email.
No Separate Holding Company Is Publicly Shown
There’s no public filing that points to a separate holding company in the way large conglomerates report structure. For shoppers, the meaningful layer is the operating LLC named on the privacy page and on site copyright lines.
Retail Listings Don’t Equal Ownership
Retailers list and ship Firmstrong bikes, but retail presence doesn’t change who controls the brand. If you want to confirm control, follow the five-step checklist above and read the legal pages first.
How This Ties Back To Your Buying Decision
Knowing the operator gives you a handle on service quality, parts pipelines, and product cycles. If you like the ride feel on a Sixthreezero cruiser, you’ll probably feel at home on a Firmstrong with the same wheelbase and bar sweep. If you prefer a different saddle or a lighter wheelset, you can often swap parts across the sibling lines without drama.
Price swings also make more sense when you know the structure. Promotions that hit both labels at once often reflect shared inventory planning. When sizes or colors go missing on one site, a quick check on the sibling brand often turns up the same fit in stock.
Where You Can Read The Source Lines
Two links anchor the answer. The privacy page on the brand’s site names the operating company and the DBA. The USPTO site shows how trademark ownership works and lets you search filings tied to any mark found on frames, boxes, or web pages. Both are public, free, and maintained by the responsible agencies.
Why The Question “Who Owns Firmstrong Bikes?” Keeps Coming Up
Beach cruisers attract first-time buyers who want simple, low-maintenance rides. Multiple labels in the same niche can be confusing, especially when colors, geometry, and specs overlap. People type “who owns firmstrong bikes?” because it cuts through marketing and gets to accountability—who stands behind the warranty and who fields your email when a shipment is late.
Bottom Line For Shoppers
The brand you’re looking at is part of the Sixthreezero umbrella, operated by Sixthreezero Enterprises, LLC as spelled out on the Firmstrong site’s legal page. That structure is common in the cruiser space and, for most riders, it’s a net positive. You get a steady supply of parts, straightforward support, and models that stick with easy-riding geometry. Do the quick checks above and you’ll be set.
