I missed the premier on Sunday, but it looks like classic English roadsters feature pretty prominently in this new PBS series. Oh yes, the actresses are beautiful also

From the promo shots, it looks like Jenny rides a Phillips, Cynthia a Triumph, and Chummy is on something with rod brakes. The trailer shows a modern Gazelle, but only a total wonk would notice that...
