Uber is getting serious about its bike-sharing aspirations. The company just announced its purchase of Jump, the bike-sharing platform featuring "electric, dock-less" bikes. Previously, Jump bikes were available in the Uber app as part of a pilot program. Rather than going to a specific rack in the city, bikes from Jump can be dropped off and locked up wherever it's legal to park a bike. Details are scant at the moment, but it looks like you can order a bike as easy as you'd order a black car or Prius. You can also continue to use the Jump app if you'd rather.
