Biketube Air Handler Mini Two-Stage Bicycle Pump
Biketube Air Handler Mini Two-Stage Bicycle Pump
Two modes. One pocket-size pump.
The Biketube Air Handler Mini pairs an aluminium barrel with high-volume and high-pressure pumping modes, giving you a compact bicycle pump for roadside tyre inflation.
Small enough to carry
The supplier lists a 6.3-inch length and a weight of less than 4 oz. Check the space in your jersey pocket or seat bag before choosing where to carry it.
Start with volume, switch as resistance rises
Begin inflating a flat tyre in HV (high volume) mode. The supplier advises HP (high pressure) mode for higher-pressure tyres above 40 psi when pumping in HV becomes difficult. HP moves less air per stroke and requires less force to reach higher pressures. The 40 psi figure is switching guidance, not a maximum pump pressure or a target for every tyre; follow your tyre’s pressure limits.
Push on, then lock the head
The head fits Presta and Schrader valves. Push it firmly onto the valve and flip the locking lever up; the source describes a push-on connection without threading or disassembly. Support the pump head with your other hand while pumping to avoid straining the valve. Push the lever back down before pulling the head off.
Keep the valve opening protected
One pump, a valve-hole plug and a spare rubber grommet are supplied. Keep the plug in the pump’s valve hole during storage to help keep contaminants out; the second grommet is supplied as a replacement if the first becomes worn.
