Founded by Steve Rink.
Erick Bartoldus, www.fatbmx.com: Powerlite is an old school BMX company originally called Peddlepower started by a guy named Steve Rink, in Orange Ca. Then it was sold in the mid 80's to a guy I don't know. Then in 1990 Rich Long the (president of GT) purchased Powerlite and the rest is history. Powerlite is known for its Powerbend handlebars, and its high end racing frames and components.
Erick Weinstetter, powerlite.wordpress.com, april 2012: Powerlite got its start as a bike shop. Peddlepower was a bike shop located on East Grove Ave. in Orange, CA. (...) near the famous Western Sports-A-Rama track. It was one of the first BMX tracks in America. All the legends from Stu Thomsen, Dennis Dain, Greg Hill to Tinker Juarez raced this track often. The bike shop was run by Steve Rink. Being close to such a early and famous track helped launch the shop into sponsoring a team. Early riders included “The Red Baron” himself , Dennis Dain. Dennis went on to fame racing for Redline and Cooks Bros.

In 1977 it appears they released their first production bike, the SR. The decals on them used the bike shops name, Peddlepower.
Ad in BMX Action august 1978: Strong 4130 chrome-moly frame and forks. Lightweight frame (under 4 pounds). Lightweight fork (1 pound, 10 ounces). Rigid aerospace design -no flex.

The stem appears to be identical to the DG stem except the decals. It is unclear what colors this stem came in. An Everything Bicycles ad shows the stem in polished aluminum.
1978 ad
Oz, BMX Action september 1979: Anyway, what happened was that there was this Peddlepower company in the West that manufactured BMX equipment and was getting ready to go buns-out into promoting their products. And then there was this Peddlepower company in the east that was totaly separate, but would get a bunch of free advertising if the western Peddlepower company didn't do sometting. So the mild-mannered western Peddlepower company aimed their Secret Star Ring at the planet Jupiter, spun around twice, shouted, “SHAZBAH!", and bingo . . . Powerlite! (...) The name’s changed but the frame's the same.
