Brompton M3L in British Racing Green. A Brompton is the perfect bicycle for the city. It folds down to a portable, practical size so can be taken on other forms of public and private transport. It can also be taken inside (homes, offices, bars) so it is a lot less likely to be stolen. Its ride position and agility are more than a match for conventional bicycles. Small wheels mean fast acceleration from red lights and increased maneoverability through busy streets.
