Issue
Phone holders don't fit on Citibike's weird handlebars.
Almost all phone holders are designed to fit cylinders and Citibikes are wide and rectangular. People need their phones out to know what dock to go to beforehand, and to navigate to the docks — it's hard to memorize the map, and annoying to keep pulling out a phone to check to see if a dock is full.
Solution
I made a phone holder that uses a bungee cord system, instead of a screw mechanism.
I created a phone holder to specifically fit the irregular handlebar shape of bike share bikes, so people can check their GPS and dock availability while they're on their bike in a safe way.
