Another report of a beautiful single bike made by Cyfac is here. That review includes one of the best paragraphs I've ever seen in a bike review:

"For the (very) well-heeled seeking a true hand-built rarity, the Absolu presents a compelling option. Cyfac even offer a two-night package – including a stay in a chateau and tours of local wine cellars – for customers who would like to collect their dream machine in person. Sip and enjoy an Absolu if you have the funds, but mere mortals will likely have to look elsewhere."

I didn't know Cyfac made tandems, but I am fortunately only a "mere mortal" and so I'll have to appreciate it from afar. No picking up my custom bike while sipping the local vintage wine for me unfortunately!
