GIYO Portable Bicycle Mini Pump with High Pressure and High Volume Modes, Stored Flexible Hose and Presta Schrader Head for Road and Mountain Bike Tires

Compact hand pump for bicycle tires

This GIYO portable bicycle pump combines selectable HP and HV modes with a flexible hose that stores inside the barrel. The supplier photographs show a black engineering-plastic barrel, a silver aluminum-alloy handle and a frame bracket for carrying the pump on the bicycle. This listing follows the construction and dimensions shown in these source photographs.

High-pressure and high-volume modes

The end selector is marked HP and HV. HP is the high-pressure setting and HV is the high-volume setting, allowing the rider to choose the pumping mode for the tire being inflated. The supplier graphics state an 80/120psi reference range. Inflate according to the tire and rim pressure recommendations and use a separate pressure gauge when needed; the pictured pump has no built-in gauge.

Stored flexible hose with threaded head

The flexible extension hose is kept inside the pump body under a dust cap. Withdraw the hose for use, then return it to the barrel for storage. The flexible connection gives room to position the pump while the head is attached to the valve.

Presta and Schrader valve configurations

The source close-ups show the threaded head in Presta and Schrader configurations. Use the configuration illustrated for your valve, with the parts correctly seated, then connect the head and pump. The valve comparison image is included below for reference.

Carry size and frame bracket

The source gives an approximate closed length of 205mm, a hose-extended reference length of 330mm and a fully extended reference length of 444mm. Product reference weight is approximately 113g. Measurements are approximate. The photographed frame bracket retains the pump alongside the frame; compare the bracket mounting points and available clearance with your bicycle.

What is included

One pump with its stored hose and the frame bracket shown in the source packaging. Bicycles, wheels, valves and other items used to demonstrate installation are not included.
