I keep a full size pump at the office and at home and carry small inexpensive pumps on the bikes. All but the cheapest of the cheap have worked well. They eventually wear out through breakage or seals going bad. I have found my 26x1.75 65psi tires easier to pump than my 100psi road tires. My next inexpensive frame pump will have a retractable hose and small foot pegs. My current inexpensive pumps have psi gauges. I mainly use the pumps to charge my AirZound 115dB bike airhorn.
