I just tried the bicycles out at Science World, very cool. They're easy to ride like cruisers, have 3 speeds (the first gear is for going up hills, the second gear is go on flats, the third gear is for going fast on flats/going down hills). You don't have to wear full out bicycle attire to ride these, whether you're in a full out business suit or in beach wear, these bicycles look good and work either way.
Membership is $78 a year or $28 a month or $5 a day and your first half hour of EACH RENTAL is free. For example, I get off at Waterfront Station, get a Bixi, ride 8 minutes to a station near my work, and return it. That ride is free. I get a Bixi at 10am to go to a client meeting in Gastown, 15 minutes there, that's free. Return trip is free. Going to Waterfront to commute home is free. The first 30 minutes is free to encourage short frequent trips. The next 30 minute of a trip is $1.50. Say I want to ride around Stanley Park, that takes about 40 minutes. $1.50 is a heckuva lot cheaper than using the rental shops. The third 30 minute period is $3.00, the fourth and subsequent is $6.00, I don't see anyone using a Bixi for more than an hour at a time though.

I can really see this program taking off in Vancouver, especially for those who aren't hardcore cyclist but need a good, quick, recreational way of getting around casually, like me. I wish I had a bicycle downtown to quickly ride from Waterfront to work as walking and bussing both take way too long.
