Houston officials rolled out a small bike share program last May with three kiosks and 18 bikes downtown.
What's surprising is how popular the service turned out to be. In less than eight months of operation, 1,200 people joined and checked out bikes 2,000 times.
Houston Mayor Annise Parker says in March the city will expand to 200 bikes at 24 kiosks in Downtown, Montrose, Midtown and the Museum District.
"The collaborations that we are making will make Houston a more bike-friendly city, will expand our transportation options. And the more of us who get get out and about and enjoy the fact that we have great weather most of the year, will allow us to be a healthier city."
A third phase some time late this year will bring even more bikes to the Texas Medical Center, the Heights, Washington Avenue and the East End.
That rapid expansion is possible because of a $750,000 donation from Blue Cross Blue Shield of Texas.
"Bike Share has been a great program for Houston, it works very, very well in other cities. We know that with more stations and more bikes it will just take off here in the greater Houston area. And truly want to thank Blue Cross and Blue Shield of Texas for their support."
Right now, you can check out a bike at City Hall, Market Square Park or Discovery Green for as little as $5 a day or as much as $50 for a year membership.
