These systems receive data from bikes, analyze it in real time and store it for further analysis. You will have access to vast data sets of bike sensory data and you will be limited only by your imagination to find ways on how to use them. You will be building systems that will make life easier for different types of engineers by providing them with tools that will give insights on how are their vehicles behaving and that, in the end, will allow them to make better products.

  • O nama
  • We are Greyp Bikes - a tech company that designs, engineer and produce high-end electric bicycles with amazing technology and performance. Our story is strongly connected to our sister company Rimac Automobili, the producer of the world's most powerful electric car. The key to our success lies in the fact that we strive to change peoples everyday lives for the better by focusing on fields we are most confident in - technology and mobility. From our humble beginnings in 2013 up until now we have grown exponentially which resulted in an even bigger brain power to make even better e-bikes! We believe that the e-bike is not a traditional bike with an electric motor, but a high-tech product that should capture all the potential of its electrical soul. That is why we start our design from the inside out, not the other way around. The Greyp corporate offices are everything but corporate. They're a place where we all come together to think, exchange ideas, do some work and have fun while doing it. Our production department is a place where all our dreams come to life and that gives us the motivation to push even further. We are not necessarily bikers. Some of us are crazy about bikes, others are just occasional riders. But all of us are fascinated with technology. We are not afraid to use technology to upgrade your riding experience.
