There is a point of diminishing returns on additional bike facilities.    There are those that will ride bicycles and those that will not.   In my age group among my friends I'm the only one who frequently rides.  Eugene is by no means devoid of bike lanes, off street paths, short cuts, and bike racks, but  bike use is still limited by weather,  fear of nighttime riding, ability to carry things,  distances to be covered with the time available.     I do not see a rental bike scheme greatly adding to the number of bike trips for these reasons.    Those that are prone to riding a bike already have a privately owned one and use it.   I would prefer to see a two year trial of the rental project and then a totally unbiased analysis of its effectiveness.   If it does not measure up to predetermined objective standards, discontinue it and reclaim as much of the taxpayers' contribution as possible.
