International ClassB62K 019/22AbstractA bicycle frame having an improved lug design is disclosed. The inner lug has a first external diameter and a second external diameter with the first external diameter being longer than the second external diameter the circumference of the second external diameter has at least two flanges which are shorter than the length of the second external diameter. The circumference about these flanges is equal to the circumference about the first external diameter of the lug. The tube to which the inner lug is joined has a first internal diameter and second internal diameter, the first internal diameter being at the free end of the tube and larger than the other external diameter. The length of the first internal diameter is at least equal to the sum of the length of the first external diameter and the flanges of the inner lug. The second internal diameter of the outer lug is larger than the second external diameter of the inner lug.Field of SearchFrames and running gearYielding One-wheel controlled Having only two wheels Arranged in tandem MOLDED JOINT And independent connection Socket or open cup for bonding material Member cast in situ MEMBER ENDS JOINED BY INSERTED SECTION With coating before or during assembling Coating By driven force fit Inserting of lamina in hole, aperture or recess of other lamina and adherence to side walls thereof Core within tube For telescoping sleeve Forming channel, groove, or aperture for reception of filler material | |
