2.4 Adjusting Seat Height
For better pedaling, safety, and overall comfort, positioning the seat at the right height is key. The rider’s leg
length is used to determine the seat’s position. During pedaling, your hips should remain level while your legs
shouldn’t suffer strain from over-extension. To determine the right seat height, sit on the E-Bike with one pedal
at its lowest point and place the ball of your foot on the pedal. If your knee bends slightly at this position, the
seat is at the right height. Additionally, when placing your heel on the pedal, your leg should be nearly straight.
