This is an aftermarket rear carrier for a BROMPTON. It's made of black aluminum and is a mini size. Screws and easy wheels are not included. Although it's for a BROMPTON, I personally used it on a Dove plus. I only tried it out for a short period, and there are no noticeable damages other than scratches on the bolts of the connection part. To install it on a Dove plus, you need to use the short metal fittings as shown in the photo, but I think it fits better than the original carrier. I believe it can also be installed on a K3, which has the same rear carrier.
