Review on WOTOW Mini Double Inlet Bike Pump, Portable On Bike Pump Fit Presta And Schrader With Repair Kit, Metal Rasp, Tire Pry Bars, Glueless Tyre Patches For Frame Mounted Road Mountain BMX Gift by Calvin Booker

This product does the job. It can bump air into your bike tires. However, I like the model with flexible nozzle because when you bump the air, your hand will move back and forth so with this bump, I have to hold the nozzle head with the valve in order to keep air not leaking out. One time, I held it hard, the top of the valve little bend. Return it and will try other model.
