In a vehicle body frame 2 of a saddle-ride-type vehicle which includes: a plurality of rear frames 11 arranged to face each other in an opposed manner; and a cross frame 12 which connects the plurality of rear frames 11 to each other, a through hole 20 is formed in the rear frames 11 arranged to face each other in an opposed manner, and the cross frame 12 is joined to the rear frames 11 at insertion portions 12i thereof inserted into the through holes 20. The arrangement provides a vehicle body frame of a saddle-ride-type vehicle which enables a high-strength joint and the reduction of weight of the vehicle body frame.

A torque transmitting, bicycle frame coupling (50) is provided which connects to the frame tubes (1, 11) of a bicycle. The coupling (50) replaces a portion of the tubes (1, 11) and has clutch teeth (3, 7) on their engaging faces. Each coupling (50) is actuated, pulling the tubes (1, 11) together and joining them through use of specialized clutch teeth (3, 7) under compression provided by a threaded lug (2), a removable-shoulder lug (9) with a removable shoulder (4) and a threaded coupling nut (5). The removable shoulder (4) makes the nut (5) and shoulder replaceable, and makes possible an additional shoulder (10) on the tube connecting end of the removable-shoulder lug (9) to keep the nut (5) from slipping onto the tube (11).

A pipe joining construction includes a tube (10; 12; 14; 16), two or more extensions (210; 220) extended from the tube (10; 12; 14; 16), a tube member (10; 12; 14; 16) coupled to each of the extensions (210; 220) so as to form a joint portion, an insert (30) disposed in each of the tube members (10, 12, 14, 16) and the extensions ( 210; 220) and having an envelope (31) and a foamable material (32) disposed in the envelope (31), a covering having an outer layer (40) wrapped around the joint portion and a foamable material (41) disposed between the outer layer (40) and the joint portion. When foamed, the foamable materials (32, 41) apply forces against the tube members (10, 12, 14, 16) and the extensions (210, 220) so as to solidly couple them together.

The present invention discloses a reinforced bicycle or vehicle frame comprising: a head tube portion for engaging a front fork and wheel; a bottom bracket portion for engaging a rear fork and wheel; a seat tube portion. Each of the head tube portion, the bottom bracket portion, and the seat tube portion being hollow, allowing for the installation of a frame reinforcement assembly to a hollow interior of each of the hollow head tube portion, the bottom bracket portion, and the seat tube portion or entire frame. The frame reinforcement assembly includes a plurality of ribs structure adapted to be approximately be perpendicular to each other. The plurality of ribs structure formed in the hollow interior and being composite material to provide stiffness to the hollow interior of each of the hollow head tube, the bottom bracket, and the seat tube portions.
