What type of batteries does the display use?

The LCD display requires 2 AAA batteries (not included). They are inserted into the battery compartment located on the back of the console. Some models also feature a self-powered dynamo, so batteries may only be needed for initial setup.

How do I change the resistance level?

The resistance is adjusted using a tension knob located on the main frame near the handlebars. Turn the knob clockwise to increase resistance and counterclockwise to decrease. There are typically 8 magnetic resistance levels.

What is the maximum user weight for this bike?

The maximum user weight is 250 lbs (113 kg). Do not exceed this limit to ensure safe operation and prevent damage.

What should I do if the display is not working?

First, check that the batteries are installed correctly and have sufficient charge. If the bike has a dynamo, ensure it is generating power by pedaling. If the issue persists, inspect the wiring connections and contact customer support.

How do I clean and maintain the bike?

WARM UP AND COOL DOWN ROUTINE

A good exercise program consists of a warm-up, aerobic exercise, and a cool down. Do the entire program at least two to three times a week, resting for a day between workouts. After several months you can increase your workouts to four or five times per week.

AEROBIC EXERCISE is any sustained activity that sends oxygen to your muscles via your heart and lungs. Aerobic exercise improves the fitness of your lungs and heart. Aerobic fitness is promoted by any activity that uses your large muscles eg: legs, arms and buttocks. Your heart beats quickly and you breathe deeply. An aerobic exercise should be part of your entire exercise routine.

The WARM-UP is an important part of any workout. It should begin every session to prepare your body for more strenuous exercise by heating up and stretching your muscles, increasing your circulation and pulse rate, and delivering more oxygen to your muscles.

COOL DOWN at the end of your workout, repeat these exercises to reduce soreness in tired muscles.
