How to Fold your Brompton Bike – Brompton Junction Melbourne

Based around a single frame and wheel size, there are three handlebar height options to choose from;
combine these with the frame, gearing and component options to build your perfect Brompton folding bike.

The Fold

All Bromptons fold the same way. Just five easy steps.

The ingenious design means that you can easily fold or unfold your Brompton in under 20 seconds. When folded, the bike is locked into a compact package, which can be carried, pushed or towed easily and conveniently stored almost anywhere. The chain and gears are protected in the centre of the folded package, which also keeps them away from clothing and luggage.

This makes Brompton bikes perfect for taking onboard public transport or putting in the boot of a car for more fun at your destination.

Handlebar heights

C/P/T Line Bromptons (i.e. the 16″ models) are offered with different handlebar heights – Low, Mid or High – which changes how upright or forward-leaning the rider is. This allows one frame size to accommodate various styles of riding.

These height descriptors refer to the distance from the ground to the handlebar grip. It’s the handlebar stem, rather than the handlebar, that differs between the Low, Mid and High models. The handlebar stem is a fixed height and not adjustable on your Brompton. This means that you never have to worry about your handlebar stem slipping when you ride, but this is also why we encourage people to test ride our demo Bromptons prior to their first purchase. Your height is not an indicator of your handlebar preference.

All handlebar height options allow for a compact folded bike size that is easy to handle and transport. Bromptons are perfect for taking onboard public transport or putting in the boot of a car for more fun at your destination.

Each handlebar option holds a different appeal for different people. Click on the handlebars to see the riding position.

C Line Brompton

Brompton bikes (parts and components) have been steadily refined over the past 40 years, but the core range remains the classic full-steel frame Brompton. C Lines are available in the widest range of options (gears, colours, handlebar heights) this classic Brompton is also the most affordable entry point to Brompton ownership.

Until 2024, C Line Bromptons were available in three gearing options; 2, 3 and 6. With the introduction of the Advance Rear Frame across the Brompton 16″ range in 2025, the gearing choice is now between “Urban” or “Explore”.

“Urban” = 4 gears (164%) = left hand shifter only
Typically chosen for flatter or short rides. The lighter weight makes it easier to stand up on the pedals and power up hills.
“Explore” = 12 gears (406%) = left & right hand shifters
Ideal for long and/or hilly rides. When you don’t know where your adventures will take you and you need the widest gear range available to ride comfortably, whatever the terrain.
