[Description] My legs shake/vibrate/bounce uncontrollably from the ankles when my calves are lightly engaged. Cadence is disrupted and jerky. Vibration can affect control of the machine. Reduced power. Adaptations. (1) reduce cadence to approximately 60 RPM, (2) when pedaling, change from flat foot position to pointed toe (fully engages calf muscles to control reflexes), (3) when coasting, slide aft on saddle and fully flex ankles (fully extends calf muscles to control reflexes). [Impairment]
