Hi guys, this might be the wrong forum for this, but considering I'm going to be commuting on my bike, I might as well post it here. I'm not sure if this is what it's called, but how do I do a running mount?

I don't see it too often around here in LA but in China, it seems like the default way people get onto a bicycle. It looks like they're running next to their bike and pushing it and all of a sudden, they step one foot on the pedal and next thing you know they're sitting on the bike and pedaling at a higher speed than if they were just to straddle the bike and start from a stop there.
