The pump locks when u lift up/open the handle on its head and there is no room to do this. How is this possible? Because this is a motor scooter(tires inflate to 30psi), and the back wheels inner spoke ring is large in diameter, limiting only a small amout of space from that ring to the long valve sticking out of my tire!
I have standard schrader valves but u must lock the handle for it to inflate the tire with a hand pump, if your using a compressor you dont with schrader values.
