Brompton hub gear setup - Sturmey Archer 3 / 6 / 12 speed
updated
There are 8 colours available (these same 8 are available in the Brompton Electric P Line range)
They are:
1/ Black Lacquer
2/ Cloud Blue
3/ Fire Coral
4/ Flame Lacquer
5/ Racing Green
6/ Black
7/ House Red
8/ Matcha Green - new for 2023
In 2022 the single / 1-speed P Line was discontinued
This year the Urban / 3-speed P Line is being discontinued
The Piccadilly Blue colour has also been discontinued
The bike will revert back (Urban / 6-speed only) to having a Zefal instead of Lezyne pump
All components will be black:
e.g. Handlebars, Brake Levers / shifters, Wheel rims, Spokes, Mudguards, Hinge clamps etc
This short video will show a solution that we have provided to a few customers - and it works!
So now - when the sprockets are worn - there's no need to throw away the old wheel and get a BWR 6 speed instead (unless you want to!)

What better way to answer than to try it
So - here we have a Brompton P Line electric ... and a B & W hard case
(of course - if you are using it for flying - you can't take the battery with you!!)
Thats not what you want to here when replacing the sprockets on your 6 speed Brompton or Brompton Electric
In 2022 there was a change to the sprocket stack
But somewhere - something went wrong - and some were sent out with a mix of the old and new sprockets - meaning they didn't fit properly
This very short video briefly explains the difference between the original, new and imposter sprocket sets - and what to look for!
The rack (or rear frame) helps it roll better when folded
A question we are now being asked a lot is - can I retro-fit a rack to my P Line (or T Line) - the answer is yes and this video shows how to do it
Tools required:
Torque wrench (for tightening nuts and bolts up to the correct tightness)
10 mm socket (for torque wrench)10mm spanner
3mm Allen key / hex wrench
5mm Allen key / hex wrench
Pump
Note: Brompton recommend that you remove the rear wheel, but we thought we’d show how to do it without rear wheel removal)(we made a video on doing removing the advance wheels here: youtu.be/vN_wMaTeYLk )

Now there are (as far as we know) a limited edition of bags available
There are 3 bags / luggage items available in the Barbour x Brompton 2022 bag collection
Barbour Brompton Metro pouch
Barbour Brompton Holdall
(these two came with the Barbour x Brompton folding bike)
Barbour Brompton City bag
In this video we do our best to show the features of the 3 bags
If we missed anything / got anything wrong - please point it out in the comments section!

Normally this time of year (autumn is when Brompton launch their new model year) there is a release of the BLACK edition bikes
This year (2022) it seems to be exactly the opposite of normal - with more silver (and gold) than black!
In this video we run through the collaboration bike between Barbour and Brompton
The bike comes with two bags - a metro pouch and a wax holdall - like the famous Barbour wax jacket - but in the form of a bag
The gold details:
A brass / gold coloured bell
A Barbour logo on the front part of the frame
A Gold Brompton Logo (in the normal Brompton Logo position)
The silver details:
Silver hinge clamp plates and levers - the new advance CNC'd version
Silver rear frame release lever
Silver Lezyne pump
(pump installation details are here: youtu.be/kL4dehkoGi0)
The new things:
Silver hinge clamp and rear frame release
Schwalbe (not Shwobble!) Marathon Almotion Transparent Skin (tan wall colour) nobbly tyres
Brooks Cambium C17 silt colour saddle
Amble Sands (based on Barbours birthplace) frame colour
The video is split into the following parts:

Will the Brompton advance roller wheels fit on a standard Brompton
To be honest we were lazy and said no - the bolt looked different
In this video we finally get around to trying it
(spoiler alert ... the answer is actually yes!)
We also show the different wheels and their diameters and weights
Co-incidentally we are often asked which bike trailer we would recommend for taking a child on the back of a Brompton folding bike
Well - we wanted to do exactly that, so thought we would give it a go - and here are the results
Spoiler alert: we will be using it a lot in the future
It's the Thule Chariot Cross trailer
We use it as a pushchair for every day use
It has a conversion kit (extra) to allow it to be used for running on rough terrain
It comes as standard with a bike attachment - which is what we used in the video
It also has the option of adding skis for cross country skiing
Then suddenly - some turned up, more or less unannounced
So we thought we would compare the most important thing - weight - against the weight of the 2 speed and 6 speed Brompton C Line electric (and the P Line)
We weighed without the battery ... which is a constant value - and would often be carried separately (partially to avoid damage to the front carrier block)
The video is in different parts:

All previous brompton sprockets (or sprocket stacks) were held in place by a Circlip
The P Line and T Line ranges use a 4-speed derailleur system which is held in place using a lock ring - as used on many Shimano and SRAM cassettes
We show you how to remove and re-install the sprockets - and the tools required - for the 4-speed P / T line bikes
Here it is!
The Brompton "Disrupt" Camo Metro Pouch - and we thought when they said Camo, it would be green!
It consists of a new mudguard stay and mudguard flap
Note: This is for the Brompton Electric only - and not for the non-Electric Brompton
The new stay gives more clearance under the mudguard and should also stop the mudguard stay bending when under weight / folding resulting in the mudguard being too close to the front wheel
Why is it important - to allow you to select the correct gear cables for your Brompton when replacing them, or changing handlebar grips or if replacing the handlebars bars
Here we give 8 clues to point you in the right direction

In 2017 (along with the launch of the Brompton Electric), Brompton changed the specification of the bars (and consequently the handlebar stem) on H-type (now known as high rise bars) and M-type (now known as mid rise bars)
Knowing which bars you have will make replacing cables and grips a lot easier
This is our first attempt at a #shorts video - so lets see how it goes
This should answer the question - yes - the Brompton Tote Bag rain cover will fit
(we have seen them in yellow or orange - orange with the Liberty Print Tote bags)
brilliantbikes.co.uk/brompton-luggage-spares/3376-brompton-tote-bag-cover.html
Now a set containing the aluminium clip set is available to all as a retro-fit option
Consisting of:
Main Frame hinge clamp
Handlebar stem hinge clamp
Rear frame clip
Seat post quick release
(and a set of bits for fitting them)
The parts are made from black anodised CNC'd aluminium

We weighed them - they are approx the same weight as the standard Brompton clamps - so you won't save weight - but they do feel / look nicer!
There isn't much - so we also run through the Brompton Electric colours available since the beginning and when they appeared / disappeared
The changes for 2022 are:
Re-branding from M-type and H-type to C Line Mid and C Line High
New Lezyne pump
Here's a video we made on the new pump:
youtu.be/kL4dehkoGi0
New catch on bag to help keep the battery connected more securely
Here's a video on the new latch:
youtu.be/9h47SRrfcjI
New front mudguard stay and flap
New colours - Flame Lacquer and Black Lacquer in addition to Turkish Green and Black
There have been reports of issues with the motor - and the battery cutting out
Brompton have been investigating - with feedback from dealers - and come up with a solution
Well - this video is about exactly that!
There are two bags for the Brompton Electric - this video applies to both bags - small and large
Hopefully there will be more bag / luggage options at some point!
This video is less about the actual bag and more about the frame inside the bag- well the catch inside the frame
The bag / battery moves just a bit too much with the old latch - so the connection isn’t tight enough - this means the battery can disconnect and potentially damage the motor
With the new latch you can see that it moves a lot less
The new latch is grey - the old latch is black
One of our viewers - David - has always told us to make sure we push the battery “home” well
There is also a new front mudguard stay / flap
(If you have a very recent C Line Brompton Electric it will already have these two changes)
A collaboration with CHPT3 that was originally supplied with the 2020 Brompton CHPT3 bike
It's now available as an after market bag
We run through the bags features
This time it's not just colours or small changes
(It is available in storm grey or midnight black - both are a metallic finish)
It's almost like a new bike - here we run through all the details (unless we missed some!) - even the box is different
We were going to compare to a C Line (Core Line) bike - but there was so much different it seemed like it would be eating into valuable time to spend with this new bike!
There are so many changes we split the video into the following sections:

Can I put a manual from wheel on my Brompton Electric folding bike?
This is a video of two subjects
1/ Is it possible to run a standard front wheel on a Brompton Electric
2/ How much effort does it take to climb a hill on the Brompton Electric with a standard front wheel versus with power
We chose one of the top 100 Climbs - these are 100 climbs around the UK that can be “collected” like football cards!
There’s an app for that! And a website describing all the climbs
Here is a link to the website in the details section:
cyclinguphill.com/100-climbs
There is a link to the Strava segment also in the details:
strava.com/segments/6691062
I last did it in June 2017 - in a time of 14:17 on my road bike (the estimated power was 162 W so it will be good to see how good / different that estimate is)
To measure the power required up the hill (by the rider as opposed to provided by the motor) we are going to fit these power meter pedals - they will show how much effort is required during the ride
We’ll do that before we set off
Then we do one run on the Brompton Electric
Then we do the same run on the Electric with a standard front wheel
1/ So - I guess that answers the question - yes it will fit
We made a video on removing / re-installing
youtu.be/_Z1-h5s5FBs
We chose Marathon Racer tyres so that the rolling resistance is as similar as possibleThe Electric ride has tan wall front and rear
The Manual version has black / standard front wheel
2/ So here we are at {if 20 - Toys Hill}
The hill has the following characteristics
* Location: Four Elms, Kent, south of M25
* Directions: Heading on B2042 towards Ide Hill, take a left direction Toys Hill

There's a new light out from Brompton - the Brompton 500 LM - so we thought we would compare it against the Brompton CatEye Volt 400, the CatEye AMPP 500
We recently made a video on mounting the CatEye AMPP 500 - the link is here:
youtu.be/dAyoW8qHmnA
Upon closer inspection we decided the Brompton 500 LM was so similar in looks and specs that we wouldn't compare it too - as it would be a bit boring
So we compare the Volt 400 and AMP 500 in the video - but there are some extra comparisons in this description:

This prompted a lot of comments
The old pump was rubbish
Can it really pump to 160 psi
Etc etc
And this constructive one:
"It would be interesting for you to pump the tyres as hard as you can, then use a gauge to check the actual pressure. I am not convinced that you could even achieve 100 psi let alone their claimed maximum. Now that’s a challenge for you."
This piqued our curiosity
So we decided to:
Install an in-line pressure gauge on a tube (we can only find for Presta valve - but don't think that should make that much difference)
and see how we get on

Here we show the colours and features / models available for 2022
The 2022 C-Line colours are:
Black
Racing Green
House Red
Black Lacquer - gloss
Cloud blue - was new for 2021
New for 2022 are:
Piccadilly blue
Flame coral
And dont forget you can mix n match
In 2021 Colours were: Black, Cloud Blue, Gloss Black Lacquer, House Red, Orange, Racing Green, Tempest Blue - so it’s goodbye (or more likely au-revoir) to Orange and Tempest Blue
Gearing
No single speed
2 speed - urban - 2 speed Brompton Derailleur
3 speed - utility - 3 speed Sturmey Archer hub
6 speed - explore - 2 x 3 Brompton BWR wide ratio
Handlebars
S - low - like this S2L - Fire Coral and Piccadilly Blue
M - mid - like this M3L - Racing Green
H - high - like this 6 speed (sorry - Explore) black lacquer - you can see the bars are higher
All bikes now come with mudguards (or mudguards and rack if specified)
Since last year (2021) - all bikes came with a front carrier block as standard
The grips may (or may not be the same)
They all come with the new pump from Lezyne (did we mention we made a video on that)
We made this video for posterities sake … so we could remember / look back at the colours / models for 2022
We first got this pump on the new C-Line black edition bikes
Previously we had done a video on the Brompton / Zefal pump here: youtu.be/mZs829pkA_Y
To be fair to that pump - we have never had a problem (bearing in mind that it is designed for emergency use - as opposed to a track / floor pump for quick / accurate inflation) - and we never lost one (apart from on stolen bikes)
The new pump also comes with the 2022 C Line electric bikes
It should be available as a retro fit pump - and will fit all models including the Superlight, and CHPT3 (titanium frame models) which don’t have the braising for fitting a pump
It will also fit all current / B75 / all older Brompton folding bikes
0:01 | Intro

We started looking into alternatives - but Brompton beat us to it by bringing out this new pump!

In recent years, the launch of the BLACK edition Brompton folding bikes marks the launch of the new year bikes - at the end of the year
This year is the same - so in November 2021 - we get the 2022 model Black edition bikes
Almost like Christmas comes early!
So let’s see what we have
We run through the colours and options and specifications
Colours:
Once again - the finish is gloss - previously it used to be a silk finish (as with my old orange one - Clementine - she was stolen and now “lost and gone forever!”)
Gloss Black - this has been a standard since the launch of the black editions - black with black extremities - and black detailing
The first thing we notice (peering in the box) is the C - denoting that it is a “Core” bike as opposed to A (Entry level - that was previously the B75) - you can see it through the carry holes
All Bromptons now come with (since 2021) the front carrier block as standard (except B75)
They also now all come with mudguards (unless a rack is specified)
The next thing we notice - in the pack with the manual is a new pump (we will cover that in a separate video very very very soon!)
Turkish Green
Turkish green (some think it’s blue) has been in and out as a black edition colourIt’s also very popular as a Brompton Electric colour (also gloss with black extremities - so this bike could almost pass as an electric look-e-likie)
The other options are “special finishes”
Sorry no “standard” colours - and no rocket red - the most popular (for us) colour last lear!
Black Lacquer
This has been available for a number of years
We have had people ask if the finish of the black lacquer is durable - our camera man has one - this is 3 years old and still looking nice
(Are the extremities black)
Flame Lacquer - new to the Black edition for 2022
We made a video on the flame lacquer bike - it seems we can’t seem to keep hold of them - they are so popular
This is the first year that it’s been available as a black edition
We are interested to see which saddles they come with and which handlebar grips
Common black detailing on all bikes:
All the detailing is black - which seems to be the theme for special edition bikes - as compared to standard bikes (like this example demo one)
Bars and Levers are black
Stem
Headset
Forks
Front mudguard
Front wheel (spoke, rim centres and hub)
Hinge clamp plates
Pentaclip
Seatpost
Chain ring
Crank set
Pedals - non-folding and folding
Rear mudguard
Rear reflector bracket
Rear triangle
Pump fitting braising is still there - even though the new pump is supplied
Rear wheel (spokes, rim centres and hub)
Gearing
The black edition is available in only 2 or 6 speeds
No 1 speed at all for any Brompton since 2021 or 3 speed in black edition
The model denotation has changed from M6L / S3R etc for this year
We could do another video on that - what do you think?
M now mid
S now low
H now high
All of these (as we are focussing on the colour) are the same model C-Line, Black Edition, Mid, Explore (previously known as M6L)
So … that is (for our video history library) the Brompton BLACK EDITION colours for model year 2022
To recap
New colour: Flame lacquer
New pump - we made a video on that here: youtu.be/kL4dehkoGi0
Rear frame (triangle) still has mounting points for the old pump - but one is not included with the bike
New model designations
Link to unboxing a Brompton (it's a B75 in this case)

We had a request - could we compare the features of the Metro (the black one) vs Borough (the blue one) large waterproof bags - we thought we would throw in the previous champion - the O-bag (the Orange one)
The video started out as a comparison of features then we decided to also see how they performed in the rain
So the video has the following parts:
0:00 | Intro
1:10 | Rain test of the waterproof bags
We did an initial test - leaving the bags out on a rainy day ...
Originally (a week earlier) we were going to leave the 3 bags on the 3 bikes - it started raining (for about 5 seconds) then stopped - we were later reminded that leaving the bikes out in the rain could be seen as Brompton abuse!
So - we left them out without bikes
We are uploading an hour of relaxing rainy day Brompton bag video - with a special appearance by our friendly robin
You can see it here (complete with robin)
youtu.be/yvserAUP178
Even this gentle rain for an hour showed that the zip on the front of the Metro bag isn't reliably waterproof (or we didn't do it up enough!)
3:57 | Extremely wet rainy day ride test
Then the forecast for the following day was for heavy rain - so we decided to re-do, get wet and give them a real test!
If you would like to see 40 minutes of getting wet riding around local roads - we could also upload that!
5:44 | About the three waterproof bags
6:27 | Rear pockets / storage
All three bags have two rear storage pockets - perfect for a thermos flask or bottle of water
They are all roll top so very waterproof
The Ortlieb winds here - the bags can be removed and used as smaller carry bags away from the Ortlieb mothership!
7:23 | Shoulder Strap
Metro bag - fixed
Borough bag - removable - but a bit fiddly
Ortlieb bag - removable - easily
8:38 | Borough waterproof bag features
Including:
Roll top
Webbing straps on the front for attaching .... stuff
Large (orange) interior
13 inch laptop sleeve
Zip up net pocket inside
10:23 | Metro waterproof bag features
Two fasteners on the front - with different settings
Zip pocket in front flap
Pen holders
Two pockets under the front flap
Orange interior
13 inch laptop sleeve
Zip up net pocket
11:50 | Brompton O bag features
Laptop sleeve with velcro fastener
Keyring holder
Pens holder
Two zip up pockets
Two velcro sealed pockets

Thanks for watching
13:40 | Outtakes
Sorry - we went wrong on some takes!
Over a year ago we started making a video showing which grips will fit which model of Brompton
It was a bigger task than we ever imagined
And some of the grips we started with have since been modified or discontinued
So we thought we would simplify it (hopefully) so - here goes
The video is in different sections - with time stamps in the description so you can skip to the most interesting part for you (hope it’s not just the outtakes!)
0:00 | Intro
This video will hopefully help with that question- will this grip fit my B75? - we have 5 + a bonus grip options
And we try the GP5
0:35 | B75 standard grips
Current / standard B75 grips - and how to remove (clue - washing up liquid)
The B75 comes with push on rubber grips
1:43 | Brompton standard pre-2017
(these may have been discontinued in 2021)
The first option would be to replace them with the standard pre-2017 grips - but these are one of the options that was (maybe) discontinued during the making of our comprehensive video
They are made of a foam like material - and should be glued on using a copydex type adhesive - making them difficult to replace
The only way we could remove the old ones was with a knife
Top trumps - Brompton branded - lightest @ 14 g
2:21 | Brooks slender short (100mm)
If you like leather - and maybe would like a matching saddle - then we already made a video on the Brooks slender grips -
These are available in the same colours as the Popular Brooks saddles - black / brown and honey (a lighter brown)
though these have also changed specification slightly since we fitted them to our old Brompton - the wording on the leather disappeared
We would say these are more for looks than comfort
Here are the new look ones ….

Top trumps - prettiest
3:46 | Madison youth
If you are looking for the cheapest option - then these from Madison will do the job with no thrills
They are actually ‘youth grips’ - hence the handy shorter length (but also a,slightly smaller diameter)
Top trumps - cheapest
Weight: 71g
4:24 | Frog short 90mm grips
If you want cheap but lock on rather than slide on - these Frog (kids) grips will do the job
Top trumps - shortest
Weight: 58g
5:00 | Ergon GP1 short / grip shift
‘Maximum comfort and best possible pressure distribution in a grip designed for touring or mountain biking. Turn the grip to get the correct support platform position.
* 202g per pair’
The most popular option are the GP1 - either Cork or Rubber
These are almost the standard ‘after market’ fit handlebar grips
Some people buy the full length version - these [show them] - and cut to length
(Do you really want to take a knife / saw to your new grips … we know it’s almost hallowe’en but …..)
The shorter version come in two finishes - rubber and bio-cork and rubber
And in 2 diameters - s and l
Top trumps - most fitting options
6:53 | Ergon GS1 short / grip shift
We didn’t want to look Ergon biased - but the nicest looking are the GS1
And they have the option of being short or really short due to the removable end
Cross country / Marathon MTB - designed for comfort over a long period of time
Only one size and one finish
Top trumps - adjustable length
Weight: 134g
7:57 | Ergon GP5 - will they fit?

The Metro Messenger Team GB bag was originally released with the limited edition Team GB 2020 (released in 2021 due to the delayed Tokyo Olympics)
Now it's available (for now at least) as a stand-alone option for all Brompton folding bikes (with a front carrier block installed that is)
Here we show the bags features
Is there a brighter light available for my Brompton Electric
The official answer is no
The complexity with the Brompton Electric is that the power goes through the front light and back out to power the rear light
It seems that most electric bikes have two feeds - one for front and one for rear - so the front light must have an input AND output
We found one (two actually) from Bush and Muller - so thought we would give it a try
We wouldn't recommend you try this - as we are not sure what it will do to the warranty
While making the video we discovered it was very long and the bit in the middle was a bit boring! But necessary if you want to see all the steps - so here are the time stamps for the three parts, so you can skip what you are not interested in
0:00 | Intro
3:00 | Light installation
13:57 | Light comparison
16:33 | End
16:57 | Outtakes
It took a while ... we had to find the correct fixings for the cable and to plug into the front carrier block (once the wires are removed - the connector is not-re-useable) - so we had to order these
We also had to find the right lights - so far we found 2 alternatives
Then we had to try it and compare!
Let us know what you think
It was made in a hurry and to be honest the sound quality vas rubbish (we can hardly bare to watch it)
But by the time we produced the video and noticed - the bike was gone
It's been 2 years and we haven't had any more - until now
We have all learned a bit more about the B75, and the spec.has settled down - that first one had some non-standard features (such as reflective sidewall tyres) to get them out quickly
So here is another effort - hopefully it's better
We also show how to unbox it (for those getting one delivered by post) and fit the pedal and saddle
The video is in 3 parts
0:00 | Unboxing / assembly
5:59 | Comparison of B75 against a standard 2021 Cloud Blue M6L Brompton
14:27 | The end bit
The Brompton Schwalbe Marathon Racer Tan Wall 16 inch
Well - it's not actually new - it was launched originally with the Brompton Explore limited edition bike
But in this year of tyre (and component) shortages - 2021, it has - maybe surprisingly been added to the official range of Brompton tyres (though availability could be limited)
The video shows the 2021 tyres available and shows the "new tyre" and how it looks
So we show all the current (2021) colours:
Black
Bolt Blue
Turkish Green
White (discontinued)
Black edition features
Gear options
rear and front gearing
Bags
We made a detailed video on the two bags here:
youtu.be/TkZyYvHr1F8
In 2020 Brompton released some of their bags in a limited edition Liberty Print fabric - a floral fabric
These were:
Metro Pouch
Tote Bag
Basket Bag
These proved so popular that in 2021 they released more liberty print bags - this time the print was called Metropolis - a bright coloured range named and representing the tall buildings of London
This time there was the addition of the Back Pack
Now in 2021 there is a more subdued third iteration - the Liberty Jonathan print - though we have been unable to find out who or what Jonathan is!
The video shows the new print and compares to the previous models
The problem is they have been in short supply (none so far this year?)
And CatEye have discontinued the Volt in favour of a new light - the Ampp
But what if you want one on your Brompton - you can't get a bracket
Here's an idea on how to mount a CatEye AMPP light
We previously made a video on how to install the Brompton CatEye Volt 400
youtu.be/J62uVJUo_HE
And how to install the Brompton Hub Dynamo (for how to fix / replace the bracket from that)
youtu.be/9sLr2xIvY0U
Let us know if you have already tried this?
Too many Brompton users out there seem to lose their pumps - we have done 1000's of kilometres (or miles) on our Bromptons and never lost one (yet!)
This video shows :
How to remove the Brompton pump
How to use the Brompton pump
How to re-install the Brompton pump
Compatibility with different models of Brompton including the B75
The Brompton Borough Waterproof Small Bag - in a navy colour is the obvious current replacement
So we thought we would show the features of this simple bag
And ... test the waterproof features in a summer storm
The bags included in the range were the Metro Pouch, Basket Bag and Tote Bag
For 2021 there are new Brompton Liberty Print bags out - the print design is named “Metropolis” and inspired by the skyscrapers of London.
This time in addition to the Metro Pouch, Basket Bag and Tote Bag - there is also the increasingly popular Metro Back Pack available in this print
Bag numbers are (we think) very limited this time around - so we thought we would show off the design
We also run through the basic features of the tote bag - as we havent covered that before.
Features of the other Brompton bags can be seen in these previously made videos

The Original Liberty Print collection

This Brompton Team GB limited edition folding bike was due to be released in 2020 for the Tokyo Olympics
The pandemic delayed both the olympics and the bike launch
Now it's here - very limited - 2020 were built (it's rumoured there is a 2021st one out there!)
This video is just a short one to show the colours and features
However - there is currently a global shortage in bicycle components - some saddles are n a 400 day lead time!
The shortage extends to some Brompton spare parts / accessories - including wheels and .... the Brompton Rack!
So we made this short video on the Brompton Rack Sack - the official bag of the Brompton rack
We installed a pair of Continental tyres AND inner tubes on the 05 April 2020 so just short of a year. (now it's March 2021)
Since then these Continental Tyres and the Brompton to which they have been fitted have done (according to Strava) 1,400 in or miles / kilometres 869 miles
This is less than would have been done if commuting were allowed!
This has included some long rides around London and the Home Counties - including riding over broken glass (that we didn’t see - just heard the crunch of glass)
The video shows how they look new compared with after almost a year and approaching 1000 miles
They are easy to fit

Brompton Borough Small Waterproof bag vs Mini O (Ortlieb) bag
Brompton Electric 2021 colours
Brompton Quad Lock Phone Mount
Brompton Electric firmware update
(We are still working on the handlebar grips)
As you can probably tell from the title - the Quad Lock was the winner
We’ve been using Quad Lock phone cases and bicycle mounts on our phones for years - so we actually look forwards to using these on our Bromptons too
The video is in the following parts - so you can skip to a particular part of that’s all you are interested in:
0:00 Introduction - what is the Quad Lock system - and what’s it used for
2:08 Whats the the difference between the mount only and the mount with universal adapter
4:32 Fitting the Quad Lock mount to Brompton S-type handlebars
7:24 Fitting the Quad Lock mount to Brompton M-type (including B75) and H-type handlebars (yes it’s slightly different)
11:01 Outtakes and using the Quad Lock for mounting some alternatives to phones
Please feel free to comment and give suggestions
"The Brompton Borough Medium (roll top) bag - is not the same as the Brompton Borough Large Roll Top bag - and not just the size"
The bag is "similar" but has different features
The kind viewer suggested we highlight the features
So, here we attempt to do that!
We haven't run through all the features of the Borough Roll Top Bag - which first appeared with the Brompton Explore bike - as we did that here:
youtu.be/4Z_ErL3sXc4
Sorry it's not the grips (yet) - they are still a work in progress
1 speed (discontinued for 2021)
2 speed - 2 sprockets and a derailleur
3 speed - Sturmey Archer Hub gear - BSR
6 speed - a combination of the Sturmey Archer BWR hub and a 2 speed derailleur
Why downgrade?
It partially comes from a question we had about Brompton Electric - can they be made 3 speed
Cleaner look without the derailleur mechanism
Simpler with less gear levers / combinations
Wide range 3 speed compared to the standard 3 speed
Steps
Remove old chain tensioner
Tip - remove tension
Tools required: 15mm spanner
Remove wheel - including fixings and chain tensioner
Here’s a video we made earlier
youtu.be/L_RQ4Y94-6M
Tip: remove air from tyre so it will fit between the brake blocks
Here's a bit about the inside of the Sturmey Archer hub: youtu.be/Wsovy4NPJLI
Remove old sprocket stackTools required: small flat head screwdriver
Tip: Whenever you change your sprockets - change your chain
Clean wheel - inside to get warm!
Install new sprocket stack - QRSPRSTACK-BWR3
Remove chain pusher etc
Shorten chain
Use chain link pliers - to remove the master link
and chain tool to cut two links outRejoin the chain
Link to chain choice and installation: youtu.be/ynlbPOPG_QI
Install wheel
Install new chain tensioner and set up gears
Hub gear setup: youtu.be/-mGfuqxilO4
Remove gear shifter
Get out and ride (when the snow stops)
youtu.be/9sLr2xIvY0U
and other on how to upgrade to a different front light
youtu.be/oK805QSHaxs
but we still keep getting asked if its possible to change the font dynamo light
So here we show the preparation required to upgrade your front light
We have STARTED making a video about the combinations of what does and doesn't work - but it's taking a LONG time!
In the meantime we needed to replace the grips on one of our bikes - so thought we would try the Brooks Cambium grips and an orange Cambium saddle as they "sort of" match with the Black Edition Raw Lacquer colour
We just passed 10500 subscribers - so thank you all - so much!
Here's a link to the video on fitting a Brompton Pentaclip (yes it is compatible with a Brompton B75 saddle) - sorry about the music!
youtube.com/watch?v=EKR2E9ec-Xg&t
We were also asked if a 2 speed would be suitable for hilly areas
So we got two bikes - and rode them up a relatively steep hill (for the South of England) 8 times - 4 times each with no power (to simulate a flat battery) and on levels 1, 2 and 3
The video has the following:
Intro
6-speed Brompton Electric
No Power / Power Level 0
Power Level 3
Power Level 1
Power Level 2
2-speed Brompton Electric
No Power / Power Level 0
Power Level 3
Power Level 1
We went home and came back on Christmas Day for ....
Power Level 2

We thought we would do a comparison - with our new power meter pedals - so we can measure effort
We failed!
