You are here
Your bike seat should be at a level that supports your full body weight and allows you to move around on the seat. Too much upward tilt can result in pressure points. Too much downward tilt can make you slide forward while riding and put too much pressure on your arms, hands and knees.
To adjust the seat height, place your heels on the pedals and pedal backwards. Your knees should fully extend in the down position. If your hips rock side to side the seat is too high. You should have a slight bend in your knees when your foot is in the proper pedaling position.
You can also adjust the seat forward and backward for better comfort. Place your feet on the pedals so the crank arms are parallel with the ground. The proper position will put your forward knee directly over the pedal axle. Drop a plumb line from the patellar tendon in your knee to make this adjustment easier to see.
