INTRODUCTION
Before using your Brompton, please read this manual noting the
sections on safety and folding in particular. While this manual is
intended as a guide, it is not a comprehensive guide to cycling
or bicycle maintenance.
To activate your 7 year extended warranty you must register your bike in the My Brompton section of our
website to record the details of your bike(s); that way, if your bike is stolen or we have any need to contact
you, we will have a record to refer to. You will be asked to enter your serial and frame numbers: the serial
number is located on a plate at the back of the main frame; the frame number is stamped on the main frame
near the bottom bracket. The information remains on the Brompton database and will not be passed on to
third parties https://www.brompton.com
If you carry out any adjustments or maintenance work yourself, please read the relevant sections of this man-
ual first, as it’s quite easy to get things wrong, and to impair the folding process or damage your bike. This
manual contains some tips and advice for using your Brompton but if you are ever unsure of how to maintain
your bike, visit an authorised Brompton dealer for expert advice. For a list of dealers, please visit our website:

We recommend having your bike inspected and serviced by a Brompton dealer regularly.
This manual conforms to ISO 4210-2
CARRYING & WHEELING THE FOLDED BIKE
• Owners are responsible for assessing the way they use the bike at all times, and should ensure that
they take due care of their safety and welfare when riding, moving or carrying their bike
• Brompton accept no responsibility for any injury caused when lifting and handling a folded bike
• A Brompton bike weighs between 9 and 14kg, depending on the equipment fitted
• Luggage fitted to the front carrier block can also weigh up to 10kg
• Owners must take due consideration of the weight of their bike and any luggage they plan to lift or
carry, and balance this against their particular physical capabilities; the circumstances i.e. route,
under-foot conditions etc, must also be considered before each lift and/or carry of the bike and
luggage
• Owners should always remove luggage from their folded bike so they do not attempt to lift or carry
the combined weight of the bike and luggage
• Whenever you are no longer able to ride your Brompton, inside a train station for example, you should
first push it as far as possible, then fold it up and roll it on the rear rollers before carrying it for the
shortest distance
• It is recommended that the folded bike is carried one-handed, most comfortably with your arm
straight and the bike to your side. The bike should be held either by the saddle, or the main frame
below the saddle, whichever is most suitable for you
• If you have to carry the bike for any distance, then it may be appropriate to swap the bike between
each hand at suitable intervals, depending on your capabilities
• Carrying the folded bike two-handed is only advisable over a very short distance, as it can only be
done by holding the bike at chest/stomach level in order to avoid knocking your legs or knees against
the bike; this requires both arms to be bent with an approx 90degree bend, which will place extra
strain on your arms
The small rollers fitted as standard on a Brompton are useful for pushing the folded bike into tight spaces.
Using the raised handlebar as a handle, the folded bike may also be pulled around on these rollers, though
this only works over short distances on a smooth surface. Remember to raise the seatpost slightly from the
fully-down position so that it does not hinder the bike from rolling along, but not so high that the bike unfolds.
The folded bike is not designed to be used as a stool, do not sit on the bike when folded.
