Bicycle floor pump Foot-operated bike pump Frame-mounted bike pump Outdoor public air compressor for bicycles. A bicycle pump is a type of positive-displacement air pump specifically designed for inflating bicycle tires. It has a connection or adapter for use with one or both of the two most common types of valves used on bicycles, Schrader or ...
These two properties are not linearly proportional to the area of the contact. For example, a 10% change in load or inflation pressure usually does not result in a 10% change in the contact patch area [ 3 ] because the load or pressure on a tire can be altered freely, and the contact patch area is affected by the tire geometry and stiffness.
The tire trademark is "Terrainarmor". Bridgestone is developing the Bridgestone Air-Free Concept Tire, which can hold 150 kg (330 lb) per tire. [13] The Energy return wheel (ERW) has the outer edge of the tire connected to the inner rim by a system of springs. The springs can have their tension changed to vary the handling characteristics.

A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
It is recommended the valve stem is to be at least 10 mm longer than the rim is deep to allow adequate room for the bicycle pump to be attached. It has a narrower diameter of 6 mm (0.24 in), compared to Dunlop and Schrader valves, measuring 8 mm (0.31 in). The weakest point of a bicycle rim is usually the hole for the valve stem.
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs , and handcycles , frequently for racing . Bicycle tires provide an important source of suspension , generate the lateral forces necessary for balancing and turning , and generate the longitudinal forces ...
An inflator stem is not used; instead, a removable cap on a valve stem embedded in the tire rim is fitted, with only the cap visible. When inflating the tire, the cap is first removed, typically with a coin, and then a "portable" dedicated inflator stem is screwed onto the valve stem. Through the inflator, the tire is inflated as usual.
The wheel is removed, the tire levered from the rim and inspected for causes of damage, and the inner tube replaced and wheel inflated. Re-inflation can be carried out by the use of a frame mounted pump or a CO 2 cartridge inflator. The CO 2 cartridge is generally a single use item only while the pump can be used to inflate many flat tires. The ...
