About 6KU

At 6KU, we believe that everyone should ride a bike, it’s great for the environment, your health… and your wallet. We created a streamlined business model that cuts out the middle-man, and allows us to offer complete bikes for the most affordable price around. After all, riding a bike should be saving you money.


This bicycle comes in a well protected box, about 80% assembled. The most complicated is already mounted from the factory and the rest is quite easy to do. You will have to place the front wheel, the pedals, the saddle and adjust the handlebar.

At the top you will see a video where one of our mechanics explains in a few simple steps how to correctly assemble this. If you do not feel confident to finish the assembly, we recommend you take the bicycle to a nearby bicycle store/workshop for a specialist to complete the bicycle build.

    I chose this bike both for aesthetics and for practicality, it weighs little, it practically goes alone, you can use a fixed gear or not, as you prefer, just by changing the side of the wheel...
