This app claims to provide the safest bicycle routes for many cities around the world - San Francisco, Montreal, Barcelona, Paris, Reykjavik and many more. This website is particularly useful for large cities with busy traffic, steep hills and/or an underdeveloped bicycle culture. The website includes a blog, with posts from anyone involved in urban bicycling. A job listings platform–for any job that involves bicycling–is part of the website: from courier to saleswoman. Additionally, the maps on the website indicate the location of bicycle and sports stores.
