Brompton Grade B

Grade B Brompton Renewed bikes are A Little Loved. They may have been on an enthusiastic test ride or adventured to a trade show. You will find 1 to 4 marks or scratches, all under 2 cm each. Like all Brompton bikes, they are hand built in our London Factory, some recently, others a bit further back. They come with a 15% discount and arrive at your door fully serviced and ready to roll. Note: all images are illustrative – every Brompton Renewed bike is totally unique.
