A molded structural bicycle component design, such as wheels and frames, which may incorporate complementary halves and at least one shear bond to allow efficient manufacturing and assembly. The molded design which may be applied in a host of different applications, including a bicycle frame and wheel, where demanding loads exist in normal use. Details of the joint and its design are provided. Integral bearings, foam tire adaptations, symmetrically opposite designs, and compression bonding techniques are described. Various cross sections may be made at different stress areas. A method of inserting a reinforcing tube in various high stress areas is also described. A host of bonding techniques including the use of electromagnetically active material are accommodated by the designs. The design may include the use of spacers in the vicinity where methods of retention of accessories or components require compressing from both sides such as the wheels, head tube, bottom bracket, and suspension attachment. The invention may include semicircular boundaries of a wheel assembly so as to define a valve stem hole after assembly.
