One of the first handbikes on the market to feature a thru-axle and hydraulic disc brakes.

A kneeling handbike with an integrated, highly aerodynamic frame, built using a manufacturing approach that allows full customization without driving up the cost.

First single, bottom-led handbike fork, improving aerodynamics while providing knee support.

The world’s first handbike to feature a fully integrated frame, delivering a major leap in aerodynamic performance. Today, this design approach has become standard across modern carbon handbike manufacturing.

Jarek's first dual-frame handbike with a very low riding position, featuring an exceptionally stiff and durable frame. Many of these bikes are still in use today.

An innovative kneeling-position handbike featuring an integrated frame, developed for Paralympic athlete Franz Nietlispach. Its advanced design exceeded UCI regulations of the era, preventing series production.

One of the earliest carbon handbikes (kneeling-position), marking an important step in the transition from metal frames to composite construction.

Jarek’s first serially produced full-suspension carbon bike, weighed just 10.2 kg, which is still competitive by today’s standards.
