New Balance stationary bicycles are a line of exercise products produced by Fitness Quest, designed to provide an aerobic workout. These products consist of a seat mounted on a base unit equipped with pedals; as the user turns the pedals, a pulley wheel inside the device provides resistance. A digital console monitors the user's workout and displays relevant information such as the time elapsed and estimated distance traveled. Occasionally, one of these components may suffer a failure, affecting the bicycle's ability to function properly.

Check the computer's power supply. If the computer uses batteries, open the battery bay and confirm the batteries have been installed properly; if this fails to solve the problem, replace the batteries with a new set. If the computer uses an AC adapter, confirm the adapter is properly connected to the computer and power outlet.
Remove the bolts securing the computer to the computer tube and lift the computer upward. Check the connections between the wires protruding from the computer and those protruding from the top of the tube. Bolt the computer back onto the tube.
Remove the bolts securing the computer tube to the bicycle's base and lift the tube upward. Check the connections between the wires protruding from the bottom of the tube and those protruding from the bicycle base. Bolt the tube back onto the base.
