Fullfjädrad

Fullfjädrad is a Swedish adjective meaning fully suspended, used to describe vehicles or bicycles that are equipped with a complete suspension system—front and rear—that absorbs shocks through springs and dampers. It is commonly used in Swedish cycling and automotive contexts to denote that the chassis includes suspension elements on both ends, in contrast to a rigid frame or halvfjädrad setups that offer limited suspension.

In bicycles, a fullfjädrad bike has a front suspension fork and a rear shock absorber connected to a swingarm or linkage. Travel is typically measured in millimeters (front roughly 100–180 mm, rear roughly 100–170 mm for mountain bikes). The design aims to keep wheels in contact with uneven ground, improving traction and comfort over rough terrain.

In cars, motorcycles, and other vehicles, fullfjädrad indicates independent suspension on multiple axles, intended to improve ride quality and handling across irregular surfaces.

Benefits include improved traction, control, and comfort; better ride stability on rough terrain and during jumps; potential for enhanced braking performance. Drawbacks include greater weight, higher cost, more complex maintenance, and potential energy loss in rough-terrain use if not tuned well. Some cyclists opt for rear-seat lockouts or progressive dampers to balance efficiency on smooth surfaces with the benefits of suspension.
