Cycling Weekly Verdict

A good alternative to CO2 pumps, combining their speed but with greater control. A well-made and sturdy product encased in an aluminum shell, with an optional silicone case that adds further durability. A 200-second usage per charge will allow between one and four tire inflations depending on size/volume and pressure. Twenty minutes recharging time, using a USB-C cable, is impressive.

Reasons to buy
  • +

    Uses USB-C cable

  • +

    Simple, fast and controllable function

  • +

    100psi max pressure

  • +

    Presta or Schrader valve compatibility

Reasons to avoid
  • -

    Not having a fully reversible and contained Presta/Schrader conversion risks losing a crucial part (Schrader pin)

  • -

    Limited number of inflations per charge

Coming in a little smaller than two CO2 refill bottles, the diminutive Cycplus Tiny E-Pump AS2 inflator packs a lot of functionality into its 65x46.5x28mm shell. It can accommodate either Presta or Schrader valves with a reversible chuck and inflate for around 200 seconds, to a maximum of 100psi.

It costs $89.00, £70.20 or €82.38 with free shipping, and is available in either a black or silver finish. Included with the pump was the silicone case, USB-C charging cable, Schrader pin or 'pillar' and a spare seal (used on its own for Presta or in conjunction with the pin for Schrader).

Over 40 years cycling in a variety of disciplines including road riding, commuting, a self-supported Land's End to John o' Groats trip, XC mountain biking and several Polaris Challenge two-day events. Adventure, escape and fun are the motivations for my riding. I also love bike and kit design and have fillet brazed a couple of framesets using Reynolds 853 steel tubing for myself. A very satisfying experience to ride your own bespoke bike!
