I'm not sure I understand how the Bixi bikes work. Do I understand, that, for example, I pay for the 24-hour access, and I can go on as many small trips as I choose in those 24 hours?
It seems that the best way to use Bixi, as a tourist, is to pretend I'm a courier, with many errands and just take it for small trips, each one less than 1/2 an hour. For example, take out a Bixi bike, bike to a new area, hopefully less than 1/2 hour away, lock it in the new station, visit the new area, shop, eat etc., and then when ready to tour the next area, get a new bike, start again on another (hopefully) less than 1/2 hour trip? Repeat for the rest of the 24 hours, and if all of my trips (which start when I take out a bike and end at the new station when I lock it back) are under 30 min., then I'll only pay $5?
So the first half hour is free. If I were to pay $5 and get a 24-hour access, and I were to go on a ride of, say, 1-1/2 hours, I'd pay for an hour usage, PLUS the $5?
