Bike Explorer:
Frame and colour

* All pricing increases and weight changes, indicated next to every option in the Bike Explorer, are calculated using an S1E as the base model with a standard steel pillar.

On all Bromptons, steel is used for the main frame and handlebar stem. The steel gives rigidity to the vital link between handlebar and pedals, which is the key to good handling. On a standard Brompton, the extremities (principally the rear triangle and front forks) are also made of steel, but on a Brompton with a superlight frame, the rear triangle and front forks are made of titanium, while an alloy headset and titanium seat pillar, mudguard stays, seat pillar and folding pedal-axle save more weight. In line with the minimalist approach, no pump is fitted. Black or red attract no surcharge; all other colour options, except Raw Lacquer (which has an £80 surcharge including extremities and main frame), have an additional £25 surcharge, both for the extremities and again for the main frame.

All-steel Bromptons

You can choose either to have your Brompton finished in one colour or in two, with the extremities and main frame contrasting. The raw lacquer option (a clear coating highlighting the braze detail and quality) is however only available for the whole frame, not in combination.
