My place has a lot of space for bicycles as it's an empty office block, but I do keep my fixie in my bedroom as I have a fair amount of space and it looks nice. Although one of these bike storage units, the 'Bookbike' from BYografia looks amazing! There are a few lovely storage solutions for Bromptons such as the Bike Box but other than plain wall hooks I've not seen many solutions for un-foldable bicycles.
The Bookbike bike/book system is perfect for books, bike and bike books!
