It's good to be ambitious, but the Paris goal of increasing share of trips from 5 % to 15 % in five years sounds somewhat unrealistic. I'd be surprised if you can double the numbers in five years.

In Helsinki, the share of trips made by bike is 11 % and the goal is to reach 17 % by 2025, in ten years time. I think even that is ambitious but not entirely unfeasible.

(However, it must be said that there seem to be vary many different ways to calculate the share of trips done on bike vs. other ways, and if you change the way you make statistics, you can of course indicate huge progress...)
