Big controversy: advertising on Bixi bikes! There have been many unhappy users who are against this surprising move to have so-called "sponsors"... namely Telus, Desjardins ( a Quebec bank ) and Rio Tinto Alcan for the bike-sharing service. Apparently, there have been reports that some of the Bixi ads have been defaced. I went hunting for them in the downtown core, but I couldn't find any. Click "here" for defaced Bixi bikes.
