Hack was a mini-scooter produced from 1921 to 1923, in Hendon, North London.
Early in the 1920s the firm offered a simple scooter. Its open tubular frame had unsprung forks, 20-inch wheels and an alloy foot platform. Positioned low down on the right of the rear wheel was a 104cc Simplex two-stroke engine with a clutch. This drove the wheel by chain. The machine was well designed as the low-mounted engine was tucked away with the petroil tank over the rear wheel.
