We did locate the Burley and it measures 27.0 between the BBs. But it wouldn't work for us as it has a proprietary BB setup with pressed in cartridge bearings. We would need much shorter BB spindles to go with our 153mm cranks.
Too bad as the owner says it only has about 1000 miles on it and I saw nothing to contradict that figure. Seems a little spindly looking but would be a great kiddie crank bike.
