Westfalia-Automative has created a towbar-mounted bicycle rack that, in a matter of seconds, converts into an extra boot by attaching a cleverly-designed waterproof lid. Portilo - the bike rack - is built to hold two bicycles in stands, rather than hang them from the frame (which is becoming increasingly difficult these days, given the variation in frame sizes between brands). The PortiloBox fits the Portilo easily with no tools needed to secure it. It's only small but, if you just need that little bit of extra space, it's ideal.
