W. H. J. Grout

William Henry James Grout (1839–1915) was a pioneering inventor and manufacturer of bicycles.

Grout grew up in Hackney and established the Tension Bicycle company in Stoke Newington.[1] He patented the Grout Tension Bicycle in 1870 which introduced several innovations including hollow forks to save weight, rubber tyres for a better ride and adjustable spokes which could be tensioned to align the wheel.[2] He also devised a portable version of a Ordinary bicycle penny-farthing, whose front wheel could be dismantled into four sections for carrying.[3]
