It was only time before we took out our most popular bike with the “next big thing”. That’s right! We have the BULLS Copperhead 3 which comes standard with the 27.5 (650b) wheels! The Bulls Copperhead 3 stands out for the high-quality appearance. Once we got the frame geometry just how we desired we made it out of the same lightweight 7005 triple butted aluminum we use on the Copperhead Plus. By triple butting the tubes we make the frame strong and stiff where it is needed most and shave the thickness of the walls down to decrease the weight making this bike one of the lightest in its price class.
