How high should the seat be?
The most important adjustment on the unicycle is saddle height. Mount the unicycle while holding on to a support and place your heel on the pedal in the down position (perpendicular to the ground). You should be able to reach the pedal in this position without leaning your body or stretching your leg. That is, your leg should be extended straight but without any strain. Next, put the ball of your foot on the down pedal. In this position, your knee should be slightly bent. To adjust the saddle, loosen the saddle post clamp, bring the saddle pillar to the desired position, then tighten the bolt securely. A loose saddle post clamp will cause the saddle to move out of position while riding. It is also important to adjust the saddle so that it is properly aligned with the wheel. If it is even slightly misaligned to the left or right, riding becomes difficult. Tighten the bolt firmly so that the saddle does not twist out of alignment.
