Magicshine Airro E-Pump Black, One Size

Tires lose air between rides, and the Airro E-Pump is a portable electric bike pump that fills a tire to the target pressure and stops on its own. Plus and minus buttons set the target, and a toggle switches the readout between psi and bar. What Our Gearhead(R) Experts Are Saying:"On a full charge, the pump brought three or four road tires up to 80 psi. Each tire finished in a little over a minute, so pre-ride top-offs stayed quick."
