Brompton Saddle Height Insert

The Brompton Saddle Height Insert was a new addition to 2015 model Brompton folding bikes, but like so much in the Brompton design world is backwards compatible

We think this is one of the best enhancements / retrofit options to the Brompton - along with the rear frame clip.

Note: If you are sharing one Brompton with multiple riders, it's not quite so useful!

What is the saddle height insert for?

The purpose of the saddle height insert is to help you set your preferred saddle height - a bit like having a memory seat function in your car - but low-tech!

When you raise the seatpost as part of the unfold operation, the saddle height insert stops it lifting up too far - to a height pre-set by you

This means that you have to spend less time in pre-ride adjustment when unfolding the bike - one quick lift of the saddle / post and you are ready to go

The insert comes as standard to all new (2015 onwards) Brompton folding bikes 

Free with new Brompton folding bikes

The saddle height insert is supplied free with all new Brompton bicycles - since 2015 - so an alternative to this upgrade would be to invest in a new Brompton bike :-)

Note: we don't fit with a new bike - it takes time for you to get to know your preferred riding height - once you have determined that, then you should fit it

Designed in-house at Brompton and patented, the saddle height insert is designed to make your Brompton riding life just that little bit easier

Fitting instructions for the height insert sleeve can be found on the download section of this page and come with it too

Tools required for installation:
5mm hex / allen key
Marker pen / tipex / masking tape
Scissors / knife

There is also an instructional seat height insert installation video on Youtube from Brompton - see below.

    Hi, do you have to use the height insert, or is it safe enough to use the extended post at it's longest? Many thanks Answer:
    No the saddle height insert is to make the saddle to the right height for you, without having to make adjustments when you ride each time. It is not a safety device. Please find a link to use and installation as follows:

    I have a new bike that had one of these included but it is too short for my little legs. Is this one longer than the standard one or is there another product which would work for me?The standard one is 126mm, I require 153mmThanks Answer:
    So sorry, this is the same length as the one that came with your bike.

    Do they have a longer one? I need an insert that is a couple of inches longer Answer:
    No there is not a saddle height insert that is longer, but we do have some shorter seat posts if you are interested please let us know.
