Bike Handle Cap - Secret Key Compartment

This part replaces the cap on the ends of bike handlebars, it's designed to press fit into the socket, however it may require some light sanding to get it to the right size.

This cap has a socket for a bike locks key, so that you can always have a spare key if you happen to lose or forget yours.
I designed this to be universal, so it should fit any key, if that key would fit into the bikes handlebars.
You may need to sand the sides of your key down so that it will fit into the handlebars.
