Trunk Position and Shoulder Angle
For the recreational rider, trunk position should be 40-80 degrees from horizontal. Shoulder angle should be between 80-90 degrees. For the road cyclist, trunk position should be between 30-40 degrees and shoulder angle should be between 90-100 degrees.

The Handlebars
Handlebar position will affect your hand, shoulder, neck, and back comfort as well as the handling of your bicycle. The width of the recreational rider's handlebars should allow hands to be slightly wider than shoulders.

Knee to Pedal
A physical therapist can measure the angle of your knee to the pedal. The closer the angle is to 35 degrees, the better function you will have with less stress on the knee. For the recreational cyclist, the angle should be 35-45 degrees. The road cyclist should have a 30-35 degree angle.

The Saddle
The saddle on your bike should be level. If the saddle tips downward, pressure will be placed on your hands and lower back. The saddle also should be a comfortable distance from the handlebars - too close, and extra weight will be placed on your mid-back and arms; too far away, and you may put extra strain on your lower back and neck.

Foot to Pedal
Position the ball of your foot over the pedal spindle for the best leverage, comfort, and efficiency. A stiff-soled shoe is best for comfort and performance.

A Note About Pedaling
Pedaling is a skilled activity that requires aerobic conditioning. You should make it your goal to work toward pedaling at 80-90 revolutions per minute. Pedaling at this rate will lessen your chance of injury.

The Handlebars
For the road cyclist, correct handlebar positioning will provide better pedaling efficiency, aerodynamics, and improved safety with cornering and braking. Your hands should be approximately 2 cm wider than the shoulders for comfort and to help ensure good handling of the bicycle.
