Summary

[edit]
Description
English: Description of a range of early Motorcycles. The Humber
The motor is built into the lower reach of the frame in a novel way, comprising four tubes as an enclosure. The motor drives a sprocket on the pedal crankshaft by chain, and by another chain to the rear wheel sprocket. A friction disc on the crankshaft prevents jerking of the chains under undue strain.
