Sour Bicycles – Steel Frames with Soul, Made in Saxony

If you’re drawn to bikes with real character, Sour Bicycles is your brand. Since 2019, the Dresden-based company has been crafting steel frames that embody pure cycling passion – from the trails of the Ore Mountains to gravel routes around the world. Whether you ride off-road, on tarmac, or somewhere in between, every Sour frame strikes the perfect balance of function, style, and individuality. “Build your Sour Ride” – your dream project starts here. Find your frame and all the matching parts in one place, from drivetrain to wheels and even the signature rubber duck. One quick delivery, and you’re ready to start building.

Sour Bicycles stands for independence, craftsmanship, and authenticity. Born in Dresden’s skate and BMX scene, the brand grew out of a hands-on culture that values creativity and self-expression. Founder Christoph Süße built Sour for riders who love to tinker, rebuild, and make their bikes their own. With the Homebrew Project, Sour brought production home to Saxony – where every frame is welded, coated, and finished by hand. This local approach ensures top quality, fair manufacturing, and short supply chains. Sour believes in steel as a timeless material – durable, repairable, and honest. These are bikes with attitude, built for riders who don’t just ride – they live it.

Looking for a bike that stands out from the crowd? Here’s why Sour Bicycles should be on your shortlist:

• Handmade in Saxony
• Durable chromoly steel
• Modern standards and progressive geometry
• Fair price for true craftsmanship

From long rides and trail sessions to gravel adventures and daily commutes – we’ve got the perfect Sour frame for your style of riding. Every model is designed with passion, tested on real terrain across Europe and beyond, and built to deliver pure ride feel and individuality.

Models like Crumble and Pasta Party show what steel can do: direct feedback, playful handling, and rock-solid stability when things get rough. Each frame is handcrafted in Saxony and ready for modern standards like thru-axle dropouts and internal dropper post routing – perfect for riders who’d rather hit the trails than make compromises.

Clueless and Purple Haze are Sour’s answer to gravel exploration. From quick after-work rides to multi-day bikepacking trips, these frames combine comfort, toughness, and style – with plenty of mounting points for bags, racks, and even a bottle of your favorite post-ride drink.

The Space Cake is Sour’s no-nonsense road machine –  fast, robust, and honest. Ideal for riders who love speed but never shy away from a detour.

Sour frames bring together the best of both worlds: traditional craftsmanship and modern engineering. Custom-butted tubes boost stiffness while keeping weight low, giving you a lively, comfortable ride with natural vibration damping. Progressive geometry ensures efficient climbing and confident descending. Add corrosion protection, durable finishes, and full compatibility with modern components – and you’ve got a frame built to last, giving you maximum freedom when choosing your parts.

• Multi-butted, custom-shaped CrMo tubesets
• ED coating for lasting rust protection inside and out
• In-house dropouts and frame details
• Compatible with modern standards (BSA, thru-axle, flat mount)
• Durable powder coating
