Amazon has been testing the idea of using bike messengers to help deliver packages within an hour in New York City, sources tell The Wall Street Journal.

The program — called Amazon Prime Now — will let the company better compete with brick-and-mortar stores, as well other instant-delivery services like WunWun, Postmates, and Instacart. Uber also has its own bike delivery service in New York City, launched earlier this year.

Amazon has reportedly been testing the service in Manhattan and is experimenting with different courier services by holding time trials between their messengers.

During the trials, messengers are reportedly given an address. They have to bike to it, take a photo of the building, and make it back to Amazon's newly-leased building near the Empire State Building in the allotted time frame. Messengers reportedly get paid about $15 an hour for 8 hour shifts. The Wall Street Journal's Shelly Banjo and Greg Bensinger saw a stream of bike messengers deploying from the building, which their source says is equipped with a lounge with foosball, pool, air hockey, and an arcade for messengers to use between deliveries.

Currently, Amazon offers its same-day delivery service in more than a dozen cities (as well as the Park Slope neighborhood in Brooklyn), but Prime Now would be its first attempt to take on nearly instant delivery. If Amazon offered this service as another perk of Amazon Prime (its $99 yearly-membership program that offers free, two-day delivery on tons of items as well as free streaming on many movies, TV shows, and music), the company could potentially convince its customers to use Amazon to shop for things they usually wouldn't.
