Chicago is a city that is not just bike friendly, but it's often ranked as one of the most bike friendly cities in the nation. Thousands of residents commute to work by bike each day, and the trend only seems to be growing as each year passes and as new bike lanes are installed. The GPS tracking app Strava, which is popular with bicyclists and runners, has recently launched an interactive map tool that shows its mapping data from 2014 and 2015. It's quite convenient to use, as a slider allows the user to effortlessly compare both years' worth of data at the same time. Users logged 115 million rides with the app, and it's clear that more folks are using the particular app when commuting by bike in Chicago. The most noticeable change between 2014 and 2015 is that the Bloomingdale Trail is now a major hotspot for riders.
