it was an automatic shift 2 speed igh
The now discontinued Ikea Sladda bike was fitted with the now discontinued SRAM Automatix two speed. SRAM ceased production of their entire line of IGHs in early 2017.
Sturmey-Archer currently offers a manual ('kick-back') shift two-speed, the S2, and an automatic shift, the A2. Both offer a 1:1 low gear and a 1:1.38 high gear.
In 1970 cycletourist Colin Martin rode from England to Australia on an Alex Moulton bike fitted with a Sachs (the company was later purchased by SRAM) two speed hub and two chainwheels and two cogs. The bike therefore had a 'flat land' two speed range and a 'mountain' two speed range. The chain was moved by hand in response to conditions encountered.
