In order to achieve a smooth and comfortable ride, you must ensure that the bike is stable and secure. If you notice that the bike is unbalanced during use, you should adjust the Left & Right Rear End Caps (No. 32L & No. 32R) located beneath the rear stabilizer. To do so, simply turn the dials on the Left & Right Rear End Caps (No. 32L & No. 32R) until the bike becomes levelled with the floor surface. Turn counter-clockwise to raise and turn clockwise to lower.
