Uber is a ride-sharing service available in hundreds of cities around the world. Like Lyft, you can book your trip, communicate with your driver and receive text updates when they get close -- all from the Uber app on your phone.
Uber has been in the news in recent weeks due to a fatal pedestrian crash with one of the company's self-driving cars. The company has since stopped its autonomous vehicle testing in Tempe, Phoenix, Pittsburgh, San Francisco and Toronto.
On Jan. 31, Uber announced plans to pilot Uber Bike by Jump, an electric bike-share program. Its bikes come with a feature called "e-assist" that's supposed to make it easier to climb hills.
