Tyre pressure is important for both comfort and safety. Please note the following tips for ensuring a safe and comfortable ride.

It is important to keep your tyres well-inflated; soft tyres increase pedalling effort, wears tyres down quickly and has an adverse effect on handling. Keeping your tyres well-inflated is highly recommended.

The most appropriate pressure depends on your weight and preference. It’s also worth remembering that a very hard tyre isn’t always faster. A hard tyre might be faster in the velodrome, on a rough road a lower pressure will deflect more easily over uneven and rough road surfaces and therefore roll faster and make the ride more comfortable. Generally, a slightly lower pressure in the front wheel and slightly higher in the rear is recommended, this accounts for the different weight distributions between the two tyres.

Brompton bikes (A, C, P Lines) are fitted with Schrader valves, allowing various methods of inflation. To inflate your tyres to the recommended pressure, we recommend using a track / floor pump with a gauge, or an air-line found at petrol/gas service stations. In addition, depending on your bike model, a pump is sometimes installed on the rear frame of the bike.

However because it doesn't have a gauge, we only recommend the usage of this mini hand pump for road side emergencies, and to use a track / floor pump with a gauge at your earliest convenience to ensure the pressure is within the suggested range written on the sidewalls of the tyre. 

The table below shows recommended tyre pressures for tyres supplied on Brompton bicycles:

Recommended tyre pressures are the same for both the electric model and standard Brompton.
