The 'Zenstem' is a bike stem that allows people who use it to turn their handlebars around.
Once attached to a bike, the device works via a contraption that can rotate 360 degrees. When users need to store their bike away in a confined space, they can turn the device as needed. A clamp holds the handlebars in place -- whether they are in standard riding positions or have been rotated to rest vertically.
The bike stem would be perfect for people living in cities or in less populated areas, as they could resolve the problem of not fitting into public bike stands that have countless other bikes on them. They could also fit well into cluttered garages, making them the perfect space-saving device.
