Bumblebee | My parents are enjoying a cruise around the Baltic this week. Their first port of call is the wonderful wonderful Danish city of Copenhagen. They sent this photo of the distinctive Nimbus motorcycle on display at a museum. The nimble and reliable in-line four 750cc engined workhorse became a staple mode of transportation for the Viking population. The Type C was introduced in 1934, when this model is from, and continued in very much this form until 1959. Its nickname was Humblebien (Bumblebee) due to a buzzing exhaust note.
