Biking to work every morning on your citi bike is a healthy way to commute. As summer gets closer (FINALLY!) I found my self trying to bike with beverages. Though doing this with one hand even though will make you expert rider. it's pretty hazardous even for seasoned bikers. This is the first iteration of my solution. Simply attach to the handle bars and ride away.Simply print in 2 steps and join pieces. You can use some 12 inch bungee chords to attach this to the handle bars. Or simply double loop the existing bag holder bungee as well. Though this bungee is very stiff so it might be better off using the 12" bungee's you can find at homedepot.
