A magic carpet', a transport solution to the corners of any city in the world. That was the vision in 1975 when we started, and it has guided us ever since. Brompton is defined by the ingenious engineering of our founder Andrew Ritchie. And by collective courage to do things differently. Across our West London factory and expert welding division in Sheffield, a team of 300+ engineers, designers, skilled fabricators, makers, inventors and manufacturers work to make the world's best folding bike.
See how we do it in the 360-degree factory tour below.
In our eyes, whether it was intended or not, the Brompton is a bike with personality. And so is the place where it's built. Many of our factory machines, designed and made by us, have parts named after the people that created them.
All Brompton bike frames are built by hand. The steel frames are pieced together using a process called brazing. Our brazers are trained in-house for 18-months. Some Master Brazers have been crafting our bikes for over 18 years. A small signature at the bottom of every frame marks the maker.
The titanium framesets are TIG welded in our specialist factory in Sheffield, 300 km north of our London Factory. This process requires a high level of skill and coordination between hand, foot and eye. Like brazing, each craftsperson has a signature style, their welds as unique as handwriting.
Between 7 am and 4 pm, the sound of collective invention quietly hums through the building.
