FitCrank is a Polish company founded by siblings Karolina and Michał. The idea for their invention was born during the pandemic when many sports facilities were closed, and access to training was limited.
Michał, a physical education teacher and avid cyclist, was aware of the benefits of cycling but missed the variety of workouts available at the gym. Inspired by this need, he decided, along with Karolina and Andrzej, to create a solution that would enable exercises previously impossible during cycling.
It took over two years of designing and testing various prototypes to find the perfect solution that could be applied to existing bikes without altering their structure. Their determination and commitment led to the creation of FitCrank – the world's only patented bicycle crank that, once installed, allows you to perform exercises previously unavailable on your bike.
