After You’ve Gone - Season 3 Episode 8

Jimmy is unenthusiastic when Diana puts Alex forward for a scholarship to a private school,causing her to accuse him of indifference to his son's future – as well as being unmanly. So he buys a motor-bike to appear macho. Unfortunately it's a kiddies' model but it comes in handy at getting him through a traffic jam to wish Alex good luck – even if it reduces his status with biker Stella.
