A bicycle suspension assembly 41 elastically supports a first frame member 34 to a second frame member. The suspension assembly preferably forms a bottom bracket unit that allows the rear frame member to pivot about the axis of the bicycle crank axle without any adverse affects to the drive train assembly. Preferably, the suspension assembly 14 includes a first suspension member 41, a second suspension member 42, a first bearing unit 44, and a shock-absorbing structure 43. The first bearing unit 44 is operatively disposed between the first and second suspension members 41,42 to movably support the first suspension member 41 for rotation relative to the second suspension member 42 about a center pivot axis. In the preferred embodiment, each of the shock-absorbing structure 43 includes a plurality of biasing members 43a. Preferably, the suspension assembly includes a second bearing unit 44 that is axially spaced from the first bearing unit 44 along the center pivot axis.
