Sidney
Urban Fixie bike
Back in 2016, a dream was born. At Siroko, we pledged to make every effort to change the lives of the people around us for the better. And there is only one way to change the world: by doing what you are passionate about.
Six years later, and thanks to your endless support, we can take a giant leap forward in our most ambitious project. Now, our top design and cutting-edge technology are put at the service of the true sport and nature lovers. Our Siroko Sidney fixie bike is here to revolutionize city transport and the way people interact with their surroundings and with the space they share with each other. Turn every journey into a challenge, a pleasure, a way to tell the world that you are unlike anyone else. That you fight every day for the environment, for our nature, for our planet. That you constantly strive to take care of your health and the health of the people around you by doing what you truly love: pedaling.
We dreamed of changing the world and now we are one step closer. We dreamed of creating the perfect machine and today it can be yours. Discover the Siroko Sidney fixie bike, discover a new way to transform the system.
(The photos show a size 55 bike with a 60 mm rim depth and bullhorn handlebar).
The most complex parts of the bike come pre-assembled. You will need an allen key (hex key) and a wrench (adjustable or fixed-size) to adjust it to your liking (tools not included). You will also find wheel decals that you can put on the rims. In cooperation with our friends at Santafixie, we have put together a video that will guide you through the assembly of your new bike.
