Traditionally if you needed to inflate your tires on the go you had two options to choose from, the trusty mini pump or the quick and efficient CO2 inflator. Recently a third option has been creeping onto the market in the form of small portable battery-powered air compressors.
Cycplus sent me its full range of e-pumps and I have been putting them to the test to see how they compare to each other and whether they have the performance to leave the best mountain bike pumps out of breath.
