Double stroke function that both the in and out pulling the handle for air flow ensures the tires, as practical. I confess to being absolutely incapable craft (which affects mostly inflate on the ability bicycle tires). Nevertheless, even me (after a short time intensive study of the air pump apparatus) managed to fill the tires successfully with sufficient air It is also convenient that the pump including balls can be inflated (the corresponding valve is supplied), appropriately in view of the coming summer More from the pump I did not expect, I do not need more this respect, particularly as a very good price performance ratio, 5 stars and a clear recommendation from me.
