Abstract: A longitudinally adjustable assembly for a bicycle seat has a seat tube, a seat post and an auxiliary hoop device. The seat tube has an inner surface and multiple longitudinal grooves formed in the inner surface of the seat tube. The seat post is slidably inserted into the seat tube and has an outer surface and multiple protrusions. The protrusions are formed on and protrude out from the outer surface of the seat post. The protrusions are respectively slidably mounted in the longitudinal grooves to allow the seat post to longitudinally move along the seat tube. The auxiliary hoop device is mounted securely with the seat tube and around the seat post. Because the protrusions are slidably mounted in the longitudinal grooves and the auxiliary hoop device provides a pressing force for the seat post, a relative rotation between the seat post and the seat tube can be avoided.
