The new 12-speed gearing system expands the Brompton’s capabilities, matching or exceeding traditional road and commuter bikes in versatility. This innovative setup pairs a 3-speed hub gear with a 4-speed derailleur, offering a wide range of gears for tackling city streets, rolling countryside, and steep hills alike.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
