Brompton Explore 12-speed Review
Wide range 12-speed drivetrain for the Explore and Electric Explore models
More gears. More range. More possibilities.
The new Brompton 12-Speed drivetrain is an expertly engineered solution that offers more gears and more range while still delivering the compact foldability of every Brompton bike.

For when you need more
Brompton’s 12-speed drivetrain gives you the gear range of – and sometimes even more than – a regular road or hybrid bike. This unique system is more compact than on a regular bike, so you still get the lightweight, portability you expect from a Brompton folding bike.

A Combined System
The unique Brompton 12-speed system combines a 4-speed derailleur with a 3-speed hub to give you 12 gear options to cover all terrain. The Sturmey-Archer 3-speed hub is weather-sealed and virtually indestructible. The whole system is lightweight too with the 4-speed derailleur - originally designed for the ultralight titanium T Line bikes - weighing just 60 grams.

Intuitive Gear Changes
This wide range 12-speed system is easy to use. The 4-speed derailleur takes care of your primary gear changes, the ones you use as you accelerate or regulate your speed in traffic. Then you have the 3-speed hub which multiplies the 4 derailleur speeds up to 12. The hub gears do the same job that a front derailleur would on regular bike, so it feels intuitive from the first pedal strokes.

P Line Explore
With its titanium rear end, lightweight fork and next level components the P Line is Brompton’s smoother rolling, easier to carry folding bike. The P-Line Explore 12-speed models combine this with the extra gearing you need to tackle the hills more easily and take your adventures further.

Electric C Line Explore
The Electric C Line is based around Bromptons original all-steel frame, but with a powerful 250w motor to boost your natural pedalling power. With the Explore 12-speed bikes you can use this power to greater effect and take on the steepest hills with less effort.

Electric P Line Explore
Lighter and more compact than any other folding e-bike the Brompton Electric P Line weighs under 16Kg. It offers a smoother ride and is easier to carry than the Electric C Line while offering the same powerful pedal assistance. The Electric P Line Explore is now available with 12-speed gearing, so you can fly up even the steepest of hills.
If you want a compact, easy to fold, and easy to carry bike that you can ride further over varied terrain then the Brompton Explore 12-speed bikes are for you. Whether you choose the electrifying boost of a Brompton Electric or prefer the timeless charm of a traditional Brompton, the new Explore models, equipped with an intuitive 12-speed gear system, unlock a world of possibilities for your next adventure.
