Just like 50 Rebels bikes, the UNI MK comes in one frame size and can be comfortably ridden by riders between 155cm and 195cm tall. People can easily adjust like in a motorcicle.  The UNI Swing is designed for a body height of 150 cm to 190 cm. Some members of our community even exceed the 2 metre height mark and ride comfortably on the UNI MK. Nevertheless, we recommend taking a test ride to ensure your own comfort.
