The resistance on my bike doesn't change. I got a new power cord and the display works but the tension doesn't seem to change

Hi There, does this machine adjust resistance with a turn knob or via electronic buttons? If it's a crank or turn style resistance adjustment, this is usually positioning a pair of magnets near a spinning disk inside that front cover. Electrical "magnetic" resistance units use an Eddy-Current brake system which also produces a magnetic field near the spinning disk, either way the magnetic attraction properties will stop any metal (conductive) disk from spinning, or at least provide a resistance to it spinning ;o) Crank tension units have a cable and pulley system inside. Good Luck

if this is a stationary bike, look on the wheel for a hand operated knob that has a roller on the tire itself.. this is a tensioner..it will need tightened up..the tighter you go the more resistance you get.the new ones use electronic braking system..dont now how it adjusts except by the control module..

follow this steps and fix it. God bless you
Power Supply An inadequate power supply limits a Sole treadmill's speed to 7 mph, even though the display may say it is going faster. Plug the treadmill directly into an outlet without using an extension cord for best performance. If this is not possible, Sole recommends using a short 16 gauge minimum cord.
Belt Too Tight A walking belt that is too loose will slip and one that is too tight runs slowly. Adjust the tension by inserting a 6 mm Allen wrench into the hole in the right end cap at the back of the deck. This gives you access to the tension bolt. Turn the wrench counterclockwise no more than a 1/4 turn at a time to decrease tension or the opposite way to increase tension. Do not tighten more than necessary to eliminate slippage of the belt on the front roller. You must also then adjust for tracking due to increased belt tension by turning both tracking bolts on each side of the end of the rail 1/4 at a time.
Belt Lubrication Sole treadmill belts come pre-lubricated, but after the first 50 hours of use you will need to lubricate the machine again. Use only lubricant sold by Sole. The treadmill can go for another 1,000 hours of use before another lubrication if it is cleaned regularly. If the belt is running slow and you have done everything else, it may be that your belt is ready ahead of schedule. Spread an entire tube width-wise across the center of the deck. The place where your feet hit when walking or running is the ideal location for the lubricant.

ERR1 indicates a speed issue. In this case, the motor speed as reported from the optic sensor differs

from the speed setting.

Analysis: Optic sensor signal issue -- Either the optic sensor signal is not right, or it is read incorrectly, or

the signal is not reaching the display.

test the speed sensor for open or faulty. clean it, and tight the connector very well. see the diagram attached. However RUN the software calibration for easy fix it.

God bless you

you must tdst the power cord, for continuite with the DVOM see the video how to measure

When using the NordicTrack in manualmode, you can adjust its resistance by twisting a resistance knob, locatedeither in the corner of the console or on the upright support. If the treadmillbelt slips from side to side, you need to adjust its tension via bolts locatedin the back of the machine frame. First find the treadmill adjustmentbolts in the rear end of the treadmill frame, to either side of the belt. Now putin an Allen wrench into each bolt, one at a time, and turn each bolt aquarter-turn clockwise. Slip one hand among the belt and the treadmill deck. Ifthis doesn't pull the treadmill belt taut, it's still too loose. Tighten thebolts another quarter-turn. Continue testing the belt tension, then adjustingthe bolts as needed, until the belt is just loose enough for you to slip yourhand between it and the deck with no extra slack. Step onto the treadmill andwalk. The belt shouldn't bind or slip side to side. If it does, dismount andre-adjust the bolts until the belt tracks correctly. AV

1)see if the breaker is tripped
2) tight the flexible cord from keypanel vs display board
3)tight the connector display board vs lower board
4)see the main motor board is working if the signal is coming by 5vdc
5) main motor faulty repair.

20 years old! wow vintage ha well it is actually connected my friend but ur bike is well a little oldy for more resistance u see as the bike gets older the wire to provide the tension losses its tension factor or rather its ability to provide tension like our tendons and ligaments so my friend either change the wire if u can or better change the bike lol

If your bike has magnetic resistance and you changed the batteries this should make your tension work properly. Since it did not I believe that there are magnets somewhere on your bike that are wearing out. Or it could be a computer part. Your manual should tell what part you need to order and replace. I hope this information has been helpful.

Also make sure the batteries that you put in your bike are really new ones. Sometimes you can purchase new batteries at a store and they are actually a little weak. I had this problem with an elyptical trainer and I went and got other batteries and this fixed the problem.

If you are refering to a regular bicycle this means the derailer is not making the chain jump from gear to gear. You probably need a new shifter cable or the shifter cable came unhooked from the derailer. I would take your bike to a bike shop to have this reconnected and then they will adjust it for you.

If you are refering to an exercise bike then here may be your solution. From what I have seen on exercise bikes there are three different kind of bikes. I am refering to how there resistance works.

First type has a strap that wraps around the wheel. There is a some kind of a nut and a bolt that holds that strap around the wheel. You simply need to tighten that nut. The strap will stretch over time and that is why you do not have the same resisteace you had when the bike was new. Afer you tighten this you will find that regular tensioner works better.

The Second type of exercise bike has what appears to be brake pads contacting the wheel. Basically your peddaling the bike with the brakes on. Pretty simple concept. Again there should be some sort of adjustment around this pad that is touching the wheel. Probably a screw or a bolt. Some even have adjusters that you can turn with your fingers.

The new and improved exercise bikes have what is called magnetic resistance. This is where your resitance is created by a magnet and some sort of power source such as batteries or your bike being plugged into a wall outlet. If you are using batteries replace them. I found that with my elyptical exerciser new batteries made a world of difference in the resistance settings. If changing the batteries doesn't help then there may be another problem. This could be the computer. Just check your user manual and I am sure you can get it replaced.
