Compressor pump test: As practical as bicycle battery compressor pumps are, only very few models are really suitable for touring. Ideally, the dimensions correspond to those of a conventional mini pump, but compromises have to be made when it comes to weight. The Cycplus Tiny Pump Cube proves in the Velomotion test that this doesn't have to be the case. We took a closer look at the dwarf among bicycle compressor pumps.
Cycplus Tiny Pump Cube: structure and functions
With its dimensions of 66 x 45 x 31 millimeters, the small bicycle battery compressor pump is only slightly larger than a matchbox - and this already includes the removable silicone coating. The weight is also sensational: the Cycplus Tiny Pump Cube weighs just 115 grams, and without the silicone protective coating it is only 97 grams. The unscrewable and reversible valve attachment ensures compatibility with Schrader and Presta valves. It is therefore not necessary to carry a separate valve attachment. A permanently installed 7,4 volt / 300 mAh battery is responsible for the power supply, which can be conveniently charged via USB-C. The electric compressor pump is only controlled with a single switch. The switch shows the battery charge status using different color lighting modes. The tire pressure cannot be read and setting a target value is also not possible.
The compressor pump in the test
Handling the Cycplus Tiny Pump Cube is extremely straightforward. The switch is used to turn the device on and off as well as to start the pumping process. Changing the valve attachment is quick and easy, but you have to be very careful not to lose the small metal pin for the Schrader valve. That would be a disaster on a tour. It is important that the USB-C charging socket is not closed during the pumping process, as this is where the air is sucked in. Despite its small dimensions, the pump is in no way inferior to the larger models in terms of performance. A 700x23C tire is inflated to 48 bar after 4 seconds; the pump needs 6,9:2 minutes for the specified maximum pressure of 30 bar. The little pressure maker also wastes no time when charging the battery. After about 20 minutes the device is ready for use again.
