The Bay Area’s bike-share system will likely be run by Alta Bicycle Share , an American vendor that already operates several systems in North America and Australia.
A board committee of the Bay Area Air Quality Management District (BAAQMD) is expected to recommend selecting Alta tomorrow, according to a memo [PDF ] from CEO Jack Broadbent. The memo says that Alta ranked the highest out of six bidders in meeting the agency’s criteria.
If awarded the contract, Alta would run a system initially consisting of 1,000 bicycles and 100 station kiosks  — half in San Francisco and the other half in four cities in Silicon Valley . The contract would be capped at $5,969,000, according to the memo.
The Portland-based Alta already runs systems in Boston, Montreal, Melbourne, and Washington D.C., where the wildly successful Capital Bikeshare was recently reported to be nearly operationally profitable . Alta has also been selected to run systems in New York City  and Chicago , expected to launch later this year.
In each city Alta has partnered with the Montreal-based Public Bicycle System Company, which manufactures the bikes and kiosks. PBSC also makes the equipment for the Barclays Cycle Hire in London.
Alta Bikeshare is an affiliate of Alta Planning + Design , a bicycle- and pedestrian-focused transportation planning firm which has an office in Berkeley.
The system is expected  to be rolled out throughout August and September.
