Jarek's love for carbon handbikes started in 2004 with making the bike that was later spotted by a legendary athlete - Franz Nietlispach. Franz and Jarek started a project which ended up with the Carbonbike.ch. When Carbonbike went to Chris Peterson in 2015, Jarek continued his adventure with this brand, as a designer and constructor of Carbonbike.usa’s “K” kneelers.

In 2021 Jarek started his own brand of carbon handbikes – JetBike.

Since 2004 Jarek’s mission is to deliver stiff, aerodynamic, light, beautiful bikes, and to quickly respond to athletes needs and preferences.
