A slide assembly for sliding a bicycle along a rail with the bicycle oriented approximately orthogonal to the direction of travel along the rail includes clamps and support arms to connect a slide plate, known as a skid, below the bottom bracket of the frame. The skid provides a surface upon which the bicycle may slide along a rail. The assembly positions the skid at or nearly in line with a vertical axis extending through the center of mass of the bicycle, sufficiently apart from the rear wheel, sprocket, chain and pedal crank to avoid interference therewith. |

1. A bicycle skid assembly for attachment to a bicycle frame, the bicycle frame including a head tube having a top end and a bottom end, and a seat tube having a top end and a bottom end and being spaced apart from and generally parallel to the head tube, a crank bracket at the bottom end of the seat tube, a down tube extending forward at a first angle from the the crank bracket at the bottom end of the seat tube to the bottom end of the head tube, and a pair of spaced apart chainstay tubes extending backward at a second angle from the crank bracket, the seat tube, head tube and down tube being in a frame plane, said bicycle skid assembly comprising:
a slide plate, the slide plate including a leading edge, an intermediate portion, and a trailing edge, a distance from the leading edge and trailing edge being at least four inches, the intermediate portion including a generally planar segment orthogonal to the frame plane; a fore attachment, the fore attachment connecting to the down tube of the bicycle frame; an aft attachment, the aft attachment connecting to at least one of the pair of chainstay tubes; and at least one structural member, the at least one structural member connecting the fore attachment to the slide plate and connecting the aft attachment to the slide plate and positioning the slide plate below the crank bracket. |
