It is always a challenge to stay in shape these days. I think we all get a little frustrated when our exercise equipment we depend on starts acting up on us.

Thank you for your question and I understand your concern.

The resistance is controlled by how close or how far the resistance magnet is positioned from the flywheel. When the bike had the original console you would press the + or - button on the console and it would cause the resistance motor to pull on a cable which would move the resistance magnet closer to the flywheel. When the resistance is reduced, the return spring would then move the resistance magnet away from the flywheel.

To reduce the resistance, the resistance magnet (key#41) will need to be moved away from the flywheel (key#54). See image below. You will need to remove the pedal cranks (key#57) and then remove the screws securing the two left and right panels. Remove the side panels to access the tension motor (key#34), cable (key#46) and the resistance magnet. Loosen the cable and the return spring should pull the resistance magnet back away from the flywheel.

I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.

The left pedal has reverse threads, so make sure to turn it the right (as you face it from the side) to loosen it. The right hand pedal is normally threaded so you will turn it to the left to loosen it.

I use an "adjustable" wrench to remove the pedals on these but an actual "pedal wrench" can be had at most bike shops. If you need to remove the crank arms you will most likely need a crank arm removal tool.

If you have any further questions please let me know.
