Brompton 2023 Buyer's Guide

Brompton 2023 Buyer's Guide

Posted on 07 December 2022

2023 brings new opportunities, and even more innovation from our favourite British bike brand. Follow our streamlined system below to choose the ideal Brompton for you and your needs.

We’ll walk you through the process of building a custom 2023 Brompton below!


ELECTRIC OR NOT? - Empowering The Ride

You need to decide if you want a Brompton Electric or a standard Brompton (what we lovingly call an “acoustic” bike).

Standard Bromptons are excellent for many reasons. They’re more lightweight than the Brompton Electrics (weighing in at 24-28lbs depending on spec) and can fly anywhere in the world when packed in a suitcase or bag and checked as luggage. Compact on public transport and extremely agile in bike lanes and on narrow streets, the standard Brompton is designed to thrive in urban environments where space is at a premium and time is money. 

The Brompton C Line Electric is a perfect fit if you’re doing long distances or big climbs on your daily commute, or just want some assistance keeping up with cycling partners on weekend rides. If you're a performance rider or want an even more lightweight bike, the P Line Electric is 6 lbs lighter than the C Line Electric and features many premium upgrades (more on that later). The Electric models have three levels of assist, with a maximum assisted speed up to 25km/h and a battery range between 40-80km depending on variables like speed, assists, hills, wind, rider weight, etc. The Electric C Line weighs 34lbs without the battery and 40lbs with the battery, and the Electric P Line weighs 28lbs without the battery and 34lbs with the battery, making these some of the lightest e-bikes on the market. Please note that the Brompton Electric models are only available to customers able to pick up in store in Toronto!

If you plan on travelling by air with your Brompton Electric, you’ll need to leave the battery at home and ride unassisted on your trip - the battery’s 300Wh storage capacity means they’re not permitted on planes.



LINES - Who Are You?

Choosing your line of Brompton determines the weight and ideal environment of your bike. Whether you’re a ride-any-bike cyclist or a particularist who loves customizing things just how you want them, there’s a Brompton line for you.


C Line - The Artist

This lineup of bikes is perfectly suited to customization as nearly every detail can be configured for the rider’s specific needs. New for 2023, all C Line bikes are built with all-black componentry, along with black fork and rear triangle in the spirit of the wildly popular "Black Edition" Bromptons. An entirely steel frame absorbs road shock and a front carrier block means you can attach whichever Brompton bag you like. Choose between seven matt colours (including the all-new Matcha Green), or the premium Black Lacquer or Flame lacquer finishes made with only the best hand-brazed frames.

P Line - The Specialist

This is the lineup of bikes for folks wanting to shave weight and maximize performance. The 4-speed external derailleur gives you the same gear ratio as a 3-speed Brompton, but with huge weight savings without the Sturmey Archer internal hub. The cassette and derailleur weighs a mere 60 grams, reducing the weight by 8% compared to the 6-speed Brompton model. This makes this bike perfect for people carrying the bike often who don’t tackle hilly terrain and want the ultimate urban commuter bike. A front fork and rear triangle made of pure Titanium reduces weight even more while adding significantly more road-dampening properties than the usual steel frame components. Other features include a firmer suspension block for increased energy transfer, redesigned easy wheels, optional rear roller frame, and zippy Continental Contact Urban tires. Available in two premium metallic colours, the P-Line turns heads and looks as sharp as it performs.

T Line - The Perfectionist

If money is no object in your quest for the perfect bike, the T Line is worth your consideration. This bike's frame is made entirely of strong, lightweight, and flexible Titanium, making it enormously comfortable to ride and featherweight to carry - a mere 16.4 lbs for the 1-speed and 17.5 lbs for the 4-speed model, a savings of 37% over its all-steel equivalent. The carbon fork and handlebar improve handling and comfort, while the steel-armoured carbon seatpost keeps the ride comfortable.

MODEL - Where You Going, What You Doing?

The question to ask at this stage is what do you plan to do with your Brompton? Are you riding the same flat commute every day, or wanting to travel and needing the widest gear range to tackle all kinds of terrain? How far are you riding on the average trip, and how much gear fine-tuning do you want?


One - 1 Speed (T Line only)

The One is the simplest gearing option for the T Line. One gear with freewheel makes this a simple, lightweight bike without any frills, but don't try to take it travelling unless your destination's topography is very close to flat. 

Urban 2 Speed (C Line only)

This Urban is the simplest gearing option for the C Line. With only two speeds, this bike is best suited to flatter and shorter rides in urban environments. The chain tensioner pulls the chain onto two separate rear cogs - one for speed, one for climbing, without the ability to fine-tune your cadence. This bike will be 8% lighter than the Explore 6-speed option but also more limited in its favoured terrain.

Urban 4 Speed (P Line, Electric P Line and T Line)

The Urban is a good middle-ground choice for people wanting a bit more gear range without the full capability of a 6-speed Explore. The Urban’s 4-speed external derailleur and cassette weigh a mere 60g and let you climb slight hills and have one more gear choice than the 2-speed, along with a higher top gear and lower bottom gear - meaning you’ll climb easier and go a little faster on the flats.

Explore 6 Speed (C Line & Electric C Line)

The Explore is Brompton’s best-selling model, and for good reason. It’s only marginally heavier than the 2-speed (the weight of a pint of beer, to be exact), but offers a much, much larger gear ratio - meaning easier uphills and faster speeds on the flats. Most of our customers that opt for the Urban upgrade to the Explore within a year or two because they find that 2-speed gearing isn’t wide enough for their needs - especially after discovering that the Brompton makes an excellent travel companion in new cities where topography isn’t well-known. The Explore operates with a Sturmey Archer 3-speed rear hub working in tandem with a 2-speed external shifter to make a combined 6-speed bike.


SPEC - Dial In The Fit & Style It Up

Once you’ve sorted out your Brompton needs, it’s time to move onto wants! The fit of your Brompton will determine your riding posture and is governed by your height and preferred position on the bike. Folks love customizing their Brompton and colour choice plays a massive role. Lastly, choosing a Brompton bag or upgrades will make your bike uniquely your own and serve functional purposes too.


Fit - Handlebar Height

Choosing the ideal handlebar height for you is an entirely personal decision. Some of our customers come from a road-riding background, so even if they’re over 6 feet tall they still prefer to be bent over their bike in an aero “tuck” position and choose a Low Handlebar. Other cyclists who are shorter want an upright “Dutch-style” riding position so opt for the High Handlebar. We’ve got a handy breakdown below to help you decide.

 Brompton Handlebar Heights

Low Handlebar (C Line, P Line, T Line)

This handlebar is a great option for shorter riders between 5’0”-5’4” wanting a moderately upright position, or riders 5’5”-6'0” who want a very sporty position dialled in for speed and exertion. For riders above 6’0”, this handlebar is going to feel very bent-over and aggressive, like a drop-bar road bike. This handlebar is 2.5” shorter than the Mid Handlebar and not available in the Electric range of bikes.


Mid Handlebar (C Line, P Line, T Line, Electric C Line, Electric P Line)

This handlebar is our most popular as it suits riders between 5’0” all the way up to 6’2” with lots of variance on fit. For riders 5’0”-5’4” this bar will feel bolt-upright (and potentially too upright if you’re riding long distances). Riders 5’5”-6'0” will get a moderately upright position, while riders above 6'0” will find this bar to be sporty and aggressive.


High Handlebar (C Line, P Line, Electric C Line, Electric P Line)

This handlebar is the most upright of the bunch and suits riders who want a relaxed position on their bike. It will feel very upright and very "Dutch" for riders between 5’0”-5’4” and provides a bolt-upright position for 5’5”-6'0” riders, and a moderately upright position for riders 6'0” and above. This handlebar is 2.5” taller than the Mid handlebar.


Fit - Seatpost Height

Unlike the handlebar heights which are chosen based on height and riding preference, the seatpost decision depends on height and foldability. What do we mean by that? Bromptons are extremely compact, but if you’re tall things get complicated if you plan on travelling with your bike by air. Read on for more details.


Standard Seatpost

This seatpost is excellent for smaller to average-height riders with an inseam of 26”-32”. When folded, the seatpost drops entirely into the frame which means it fits in Brompton-specific travel cases.


Extended Seatpost

This seatpost fits taller folks with an inseam between 28.5”-34.5”. It sits 6cm taller than the Standard when folded, so won’t fit in most Brompton-specific travel cases.


Telescopic Seatpost

If you’re sharing the bike with a partner who is a different height than you, or you’re a tall person travelling with your Brompton, this is the seatpost for you. It stands 7” taller than the Standard when fully extended, but thanks to the telescoping construction it only sits 2cm taller when folded, meaning it will fit in most travel cases. This seatpost is suitable for riders with an inseam of 27”-39”.



Brompton is releasing new colours to the range for 2023 but offering them within specific Lines of bikes. 

If you’re after choice, the C Line and C Line Electric are your best bet. Seven matt colours cater to every taste. Matcha Green and Yellow join the cohort, while Black Lacquer and Flame Lacquer round out the offerings as the premium option, using only the best frames to highlight the brass brazing visible under the lacquer coat.

All the colours available within the C Line "acoustic" lineup of bikes (apart from Yellow) are on offer for Electric C Line bikes as well. Get your Brompton C Line Electric in whichever colour suits your fancy, from classic Racing Green all the way to premium Lacquer finishes.

The P Line and Electric P Line feature a premium metallic finish that shimmers in sunlight. These bikes keep it smart and sophisticated in either Storm Grey and Midnight Black finishes that complement any accessory choice and can be dressed up or down with Brompton upgrades in brass, black, or titanium finishes.

 P Line Colour Swatches


Congrats, you’ve configured your Brompton! The last thing to do is decide what you might want to add to spice it up. But do keep in mind - a lot of the things we’ll talk about here are even more practical than they are pretty.



A Brompton bag is a truly unique invention. Most full-sized bikes use a rear pannier rack with some combination of baskets, bungees or pannier bags, but because Bromptons fold for transport it’s often not practical to use the optional rear rack for carrying things. Brompton uses their bespoke Front Carrier Block to carry a custom lineup of bags that don’t impact the fold or steering and keep your back sweat-free. The Front Carrier Block can support 10kg / 22lbs of weight and the full range of Brompton bags allow you to carry up to 30L of essentials.

If you’re an urban commuter, the Metro Messenger lineup doesn’t look out of place at the office and comes in two sizes. The smaller Metro Zip provides handlebar or saddlebag space for a wallet, keys, and phone. Need adaptable storage? Opt for the Borough Roll-Top lineup. If you’re frequently riding in wet weather, the Borough Metro and Roll-Top bags also come in fully-waterproofed options. Daytrippers will appreciate the Borough Tote, a small shoulder-carry bag big enough for a book and water bottle, and folks regularly popping into the grocery store with their Brompton love the wide mouth and large capacity of the Borough Basket. Being from rainy Britain, every Brompton bag comes with a hi-vis waterproof cover if it’s not already waterproofed. 

If you're riding the Brompton Electric, you have your choice between the Electric City Bag Large or Electric Basket Bag. The Basket Bag swallows 20L of stuff in an open-top basket that can be cinched closed, while the City Bag Large offers a zipped business-bag style of carry with pockets galore. Both have space and a bag mount dedicated to the Brompton Electric's battery.

Rear Rack

As mentioned above in relation to bags, a Brompton rack isn’t designed primarily for carrying things to and fro, although it can serve that purpose. The main reason customers buy Brompton racks is to make their bikes more transportable.

Bromptons come stock with two small wheels in front of the rear fender that the bike balances on when folded, along with the small wheel on top of the fender. You can pull the bike along behind you like a suitcase, but you need to lift the fender wheel off the ground by lifting the bike slightly at the handlebars while moving it. This is to prevent damage to the fender, and provide an easier roll on the larger frame wheels designed for exactly this purpose. When you install a rack, the bike has four frame wheels instead of two, which allow the bike to be more stable when folded. They also make the bike more mobile - you can push it like a shopping cart on its four wheels through the store or subway station without needing to lift the front end. Read more below under “Upgrades” to learn why we recommend Easy Wheels alongside the rear rack install.

Unless you turn into a pumpkin after dark, chances are you’ll be a nocturnal rider at least once while owning your Brompton. Lighting makes the road safer for cyclists and drivers (make your presence known!) and helps you avoid road hazards that are hard to see after sundown.

If you’re buying a Brompton Electric C Line or Electric P Line, it comes stock with Busch & Muller front and rear e-bike lights powered by the battery. 

For all “acoustic” Bromptons, there are two choices for lighting - battery or dynamo. Battery lights are readily available at any bike shop, and we can certainly point you towards a great option in our shop! But if you want to stay loyal to Brompton, you can opt for the Cateye front and rear lights. These lights are very compact yet pack a punch for output and are USB-rechargeable when the lithium batteries give up the ghost.

Dynamo lighting is a real gamechanger. These lights are powered by a dynamo hub in the front wheel that generates power as you pedal, turning the lights on whenever you’re riding. The big benefit is they provide daytime running lights for maximum visibility, are fully theft-proof, work in the cold, and don’t ever need a battery swap. We have a full breakdown of your options and all pricing details here.



Many of the upgrades in this list are both beautiful and incredibly practical.

Titanium Seatpost - Titanium made its debut into the bicycle industry in the heat of the Cold War when aerospace-grade material was being produced en masse and readily available. Titanium is much stronger and more flexible than the stock-standard aluminum posts, so it absorbs a ton of road chatter and makes the Brompton much more comfortable to ride. We recommend the Ti Parts Workshop titanium seatpost as it still uses the brilliant Brompton Pentaclip for custom saddle adjustment.

Hinge Clamp Levers - The multitude of hinge clamp levers we offer make folding the Brompton much easier, which saves a lot of time if you’re running errands. Unlike the stock-standard Brompton hinge clamp levers, the ones made by BrompficationNOV Designs, and Ti Parts Workshop (sold in two sets here and here) have a slightly longer edge on one side and a spring underneath the plate, allowing you to twist the knob one-handed to open or close the fold. If you plan on using the Brompton Toolkit with your bike, choose something other than the Brompfication Hinge Clamp Plates & Levers as they don’t allow the toolkit to be inserted into the frame.

Easy Wheels - We recommend these to every Brompton customer due to their practicality. The Easy Wheels made by Brompfication, NOV Design, Joseph Kuosac and Ti Parts Workshop are wider than the C Line and C Line Electric frame wheels, allowing the bike to roll better over smooth surfaces and reducing scratches on the top of the rear fender when the bike is in transport mode. Most of these have ball-bearings inside a sealed hub to make them long-lasting and mobile for years to come. Speak to a staff member during your sales appointment to suss out which Easy Wheels are best for you. 

As always, if you need an extra hand deciding or want to chat through options with an expert, you can book a sales appointment on our website for either an in-store or remote conversation. We're happy to help!
