Custom Bike Builders

Custom Bike Building

Old Empire Motorcycles founding was born through an absolute and enduring passion for everything two wheeled and The House Of Assembly (HOA) is where we pay daily homage to the gods of speed and fuel.  Its the place where we meet, greet, drill, weld, cut, grind, turn, mill, hammer, roll and notch to our hearts content to create and display our bespoke motorcycles.

Unlike most custom bike builders in the UK we do not stick to styling ‘rules’ but focus on creating the very best we possibly can with what we are given. 

We create a handful of one off custom bikes annually which all take their names from Great British automotive, aeronautic and maritime history, a slight nod of recognition to the people who designed and built these machines for us to be inspired by today.

We also appreciate that individuals have their own conceptual  ideas that they may want to see taken from paper and turned into steel, therefore it only seemed sensible to also offer our skills and services in a way in which people could do just this.

The fact is that the time consuming and intricate process of designing and crafting a custom motorcycle is one which OEM understands well, so if you like our style then get in touch.



One of our aims is to design and craft as much as we can entirely in Britain. Working with other British manufacturers play a big part throughout OEM motorcycles, parts and clothing also.

We realise with a little foresight and selflessness that doing this may inspire others to and will eventually be of great benefit to us all as we can begin building a better future for everybody.

British Made British Pride.
