Bike Handlebar Cup Holder - Pint Glass or Coffee

thingiverse

The ring is a basic clamp that secures itself onto your handlebars, providing a sturdy hold for a pint glass or another beverage container similar in size. You'll also notice I've added an alternate, smaller design that can accommodate a standard coffee cup. To set this system up correctly, you will need to obtain two 40mm M4 machine screws and their respective nuts. Please note that the ring's bar clamp hole is slightly larger than what would be needed for a standard road bicycle handlebar. In order to compensate for any sizing differences, I recommend attaching a small strip of old inner tube rubber or several layers of electrical tape along its edge to secure a proper friction fit between the ring and your bar. Remember, safety always comes first: it's crucial not only for responsible cycling but also for common sense to ride without engaging in such hazardous behavior as drinking on a bike.
