Washcycle points to this infographic covering the usage metrics for Cabi through its 2nd Birthday. http://www.thewashcycle.com/2012/09/cabi-2nd-anniversary-infographic.html
Two numbers that jumped out at me were the single hardest working bike – only 1,850 miles ridden (no indication of how long it has been/was in service -although it wouldn’t be too hard to get that from the CaBi spreadsheet data). I suspect most people on this forum knock out that much riding in half a year or so.
The other number that jumped out was the total miles ridden (2 million). If the highest mileage bike only logged 2,000 miles, then the capacity utilization of the entire fleet must be pretty high. That is, there aren’t many bikes sitting idle. They’re all probably really well used.
Fun with cycling numbers!
