The Brompton is designed for use on the roads and well-made paths, carrying a maximum load, not exceeding 110kg (rider and luggage weight included). The Brompton is not intended for stunts, cross-country riding or extreme sports. Your Brompton should be used for its intended purpose. Misuse may lead to failure of some components and void your Brompton warranty.
Before riding your Brompton for the first time, and periodically thereafter, please pay close attention to the following:
Before or after each ride, pay close attention to the following:
Many components on a bike are highly stressed, and with high mileage, heavy loads or hard riding will eventually reach the end of their design life; in particular, aluminium alloys have a limited fatigue life. Failure in use can cause injury. You should check all load-bearing parts for any signs of damage, corrosion, or cracking, and replace if necessary. Please visit an authorised Brompton dealer for expert advice if you are uncertain.
Like all lightweight machines, the Brompton features aluminium alloy parts which have a finite design life before failure; in normal use, the risk of aluminium fatigue failure is remote, even after many thousands of miles, but the risk of failure increases with use, especially with hard riding or severe loading.
As such a failure could cause injury, we recommend that these items are checked regularly and that the folding pedals, aluminium seatpost, hinge clamp plates, handlebar and chainset be replaced every 5,000 miles (8,000 kilometres), or more frequently on a bike subjected to particularly hard use.
If the bike has been subject to a crash or impact you should stop using the bike immediately and have the bike inspected by a Brompton dealer. Damaged components should be replaced before the bike is ridden again. Any deep scratches or gouges in the aluminium parts can severely weaken the component and cause premature failure of the part.
