Brompton P Line M4R Lunar Ice *Accessories not included*

The Brompton P Line M4R in Lunar Ice is a British-made steel folding bike designed for daily urban commuting. Like all Bromptons, it folds compactly for storage or transport, making it practical for mixed journeys involving cycling and public transport. The 16-inch wheels and steel frame give it the characteristic Brompton handling and feel, whilst the 12-speed hub gear setup provides enough range for varied terrain without needing to think too much about gear selection.

If you're looking to upgrade from the stock plastic components, the H&H Gold Edition accessories offer a straightforward way to improve durability and performance. The aluminium front carrier block is CNC-machined from 6061 aluminium in a unibody design, making it stronger and lighter than the standard plastic block at around 58g. The smooth spring-release lever makes loading and unloading straightforward, and the gold colour matches the aesthetic if you're after that look. The hinge clamp and lever set comes as a pair and uses 6061 aluminium clamps with 7075 aluminium bolts, designed with an ergonomic lever profile that makes the fold a bit quicker and easier on the hands. The spring-free locking system keeps weight down and works across Brompton A, C, and P Line models. The quick-release seatpost clamp is also CNC-machined aluminium, weighing around 43g, and lets you adjust saddle height without tools—useful if you share the bike or swap between different riding positions.

These upgrades suit anyone who rides their Brompton regularly and wants components that are more robust than plastic, or riders who value the small weight savings that aluminium brings across multiple parts. The gold finish gives a consistent look if you're building a specific aesthetic. Note that these are sold separately and don't come with the bike—you'll need to source and fit them yourself or arrange fitting when you collect your Brompton.
