Sour Bicycles

Introducing the new Sour Purple Pie

The Purple Pie doesn’t just inherit the road—it rewrites it. Born from the proven DNA of our beloved Purple Haze, it carries forward that spirit of playful adventure, now sharpened with the precision of the Pinion Smart.Shift transmission.

For years, we dreamed of a bike that could merge the effortless flow of our classics with the intuitive control of modern shifting. The geometry was already there, the soul already alive—but the missing piece was a drivetrain that could keep up with every twist, climb, and descent without hesitation.

After countless rides and refinements, the Purple Pie is ready: a bike that blends heritage with innovation, speed with stability, and instinct with technology. Whether the path is smooth, rough, or something in between, the Purple Pie makes every ride feel like second nature.

Homebrew – Made in Germany

Homebrew represents the culmination of plans, chats with friends while out riding, and many late nights writing ideas down. Homebrew is the project name we gave to our on-shoring process, the project we started to make all our frames right here in Germany, one-by-one, by hand, in our own facilities.

Homebrew is the biggest step we’ve ever made as a company: moving 100% of our production to Saxony. We are so proud to be Made in Germany and will continue to grow the Homebrew project in the coming years.

Custom bikes – Painted in Dresden

We love custom colors on bikes. We’ve offered custom powdercoating, done right here in Dresden, since our very frist day of operation.

Every year with have two or three standard colors if you’re not interested in stressing out over the thousands of solid colors, fade, gradients, and pearls… but really, there’s nothing more fun than a frame in your own color!

We have a selection of custom colors, just to keep it a little simpler, but if you’re really looking for super duper custom colors, we’ve got that too.
