Bicycle seat with vibration isolation
A bicycle seat suspension can include one or more movable body members. The one or more movable body members can be configured to be operatively connected to a bicycle saddle. The one or more movable body members can be configured to change configuration when a load is applied to the bicycle saddle. The bicycle seat suspension can also include a vibration isolator. The vibration isolator can be configured to exhibit a non-linear stiffness profile including a region of quasi-zero stiffness. The vibration isolator can be operatively positioned such that, when the one or more movable body members change configuration responsive to a load being applied to the bicycle saddle, the one or more movable body members can engage the vibration isolator. As a result, the vibration isolator can isolate a person seated on the bicycle saddle from vibrations transferred through the bicycle saddle.
