Brompton Australia have a full inventory of their current stock on the web. A new 2017 M6L (new model with increased cockpit room and updated controls) is listed @ $2219.00. I know that seems a lot of money, but they are a 'keeper' and you can take them anywhere.
I started with the M6L-X low range, -12% gearing, a better gearing option. Cycling through Darling Harbour one day a few years ago (4) I bumped an Argentinian airline captain riding his prefered S model. I told me he deploys is Brompton for discovery riding in every city in which he finds himself. This led me to acquiring an S type also, simply because Brompton bikes are that good; and useful. I have even been to day surgery at RPA and been allowed to take my (immaculate) Brompton into theatre.
Because of my now age I have installed Tillers Cycles (UK) custom specific 40T chainring and guard also. The S model has a Calhoun Cycles (US) custom S 45mm riser bar. Ergon GP2 grips on both bikes also allows you to reach forward in a relaxed manner. The new 2017 M model has a similar forward bend in the handlebar stem to the S model, giving more room to more M riders.
By every definition of the word I am a cyclist, have been for 40 years consistantly, running parallel with my motorbikes and scooters, but these Bromptons offer the greatest level of personal autonomy in the widest range of circumstances of any machine I have owned. The following Sunday is a scheduled Brompton exploritory ride of 65 klms; ride- train- ride. This little bike will eat up that distance easily, and offer a huge grin factor.
