Why do I refer to the bike as a "lamplighter"? In the old days lamp lighting was a job. A lamp lighter went around in the evening usually with a ladder and lit up each gas powered lamp post in turn.
Some of the people doing this job had specialist bikes made that were very tall. Then they could just cycle between each one, hold on (or lean) and light them without needing the ladder.
The design here is classic lamplighter bike style, albeit scaled down. A real lamplighter would be over 7 foot.
