Brompton 2017 M6L Grey folding bike

Grey Brompton M6l - 2017

Grey was introduced as a Brompton model colour in 2017 and discontinued at the end of 2018 on the 2019 model range

2017 model Grey Brompton folding bike model M6L (M=handlebar type, 6=6 gears, L=with mudguards) with front carrier block

This 6 speed Brompton is just like the most popular M3L (3 speed model) but with extra gears (6 gears instead of 3) and a wider gear ratio that makes climbing hills just that bit easier.

Because the Brompton folds to such a small size means it is accepted on just about all public transport, can be stored under your desk when at work or in a small cupboard when at home.
