Redline Engineering was started in 1970 by Linn Kastan and Mike Konle in Northridge, California as a manufacturer of motorcycle components and frames. Starting in 1974, they applied their chromoly motorcyle techniques to making BMX chromoly, tubular forks and handlebars in Chatsworth, California. 1)
Redline is often referred to as the original BMX manufacturer.
In 1988 Kastan sold Redline to Seattle Bike Supply (SBS) and they relocated the company to Kent, Washington.2) Seattle Bike Supply was later acquired by Accell in 2006.

1984 Conquest Escape Vehicle bmxmuseum
The head badge states that this is a city bike - but with the fat tires, mountain gearing and cantilevers this is a worthy MTB. SunTour XC rear (1984-1985) and MounTech II front (1984-1987). It's possible that this is a 1986. Need a 1985 catalog to verify this, but the coloring and lettering is 1985 consistent.

1993 Rocky Top II
1993 Rocky Top II Shimano RD-TY20GS (1989-1994). The year is a guess, based upon the 1992 Rocky Top (and all previous Redlines) being wedded to SunTour. SunTour died in 1992, leaving Redline to finally move to better components in 1993.
