Under the leading of the eldest brother Jack three of four Taylors (all have been enthusiastic for cycling) developped their sideline business of making racing bike frames to the nowadays highly esteemed name of vintage bicycles. At first influenced by Claud Butler bicycles, since the beginning of the 1950ies their acknowledgement of french bicycle makes as René Herse and Alex Singer and the possibility to import french components has been an important kick to their reputation as an highly estimated touring bicycle and tandem builder. Also it was exceptional that Jack Taylor began early to weld (bronze-welding with so-called Sifbronze rods) bicycle frames in the absence of lugs during the war. That enabled them to built frames with non-standard angles and this decisively released tandem production. Another point was their very good connection to Reynolds, so they could fulfill their needs concerning special tube features. That's the reason why they have preferred 531-tubing, but they have also used other makes like Columbus. After not selling a huge amount of somewhat mass produced frames the Taylors began to build frames for individual demand. This has been the preliminary action to conquer the north-american market, which became a key to success since the beginning of the 1970ies, not least for the exceptional finishing of the frames. By closing their firm in 1990 they had built 8628 frames.
