When Mr Butler-Adams joined Brompton in 2002, it was making 6,000 bikes per year, and employed 24 people. The company was profitable, but in no way able to keep up with demand.
Fast forward to today, and Brompton makes 40,000 bikes a year, and has 190 workers. Its annual turnover is set to hit £28m after growing by more than a quarter in each of the last three years.
