The manual provides instructions for adjusting the drive belt on the Pro-Form 831.21813.2 but does not mention replacing it. However, since the bike is covered by a 90-day full warranty and the frame has a 5-year warranty, it may be worth checking if the repair is covered. If the bike is out of warranty, replacing the belt could be worth it if the rest of the bike is in good condition and the cost of replacement is reasonable compared to buying a new bike.

How do you get the batteries out of the battery compartment? I cannot pull them out to change them. Please advise.
