A Sybian (), or Sybian saddle, is a type of masturbation device. It consists of a hollow saddle-like seat containing two electric motors, motor speed controller boards, gearing, pulleys, and a platform on cranked axles such that a ridge on the top of the unit can be made to vibrate through a range of speeds as set using a wired external hand controller, and an upward-pointing shaft set on an angle through the ridge can be made to rotate at speeds of up to several hundred rpm, again by use of the wired remote control. Flexible molded attachments are usually supplied, fitting over the vibrating ridge and shaft which mostly have integrated dildos on their top. In use, the rider inserts the dildo into a body orifice for internal stimulation while applying pressure on the vibrating ridge with their external erogenous parts
