If this is a new bike that may be the way it is. If it worked differently in the past, you may be looking at a busted tension motor or faulty brake.

Always check the sensor alignment first. If its properly aligned, check the sensor magnet. If thats ok, replace sensor

tention belt or spring is broken. buy a new bike its not worth fixing.

Have you updated the software? Have you contacted the manufacturyouer? It may need a software update. Without knowing the make and model it is difficult to direct you for a fix. If you have a manual, look at the trouble shooting section.

follow the steps, and fix it. God bless you

Be aware that the resistance is often the part that requires repair. Resistance is managed magnetically, so often if the machine is working, but the resistance isn't setting correctly or at all, check the bolts that secure the magnets. If they are loose, the resistance will slip. If the bolts are fine, check the magnets themselves by using a refrigerator magnet and see if it is attracted or repelled by the your fridge magnet. If not, the magnets have de-magnetized and need to be replaced.

1) tight the bolts tension for magnet and clean very well. and proof..if the fail
2) go to test the magnet, use again the magnet from your refrigerator magnet, for attraction and repulsion. If do not pass the TEST replace the magnet in any Hardware such home depot, etc.
God bless you

There are three main types of resistances, the fan resistance used to provide resistance with air they push as you pedal. The second type is the belt resistance which uses a belt that runs through a brake providing resistance for the exercise bikes. The third type is the magnetic exercise bike which provides resistance which can easily be adjusted while riding the bike.

This unit incorporates an adjusting motor for the magnetic boot. This unit also uses batteries for the upper console functions I would check the batteries first and replace them, if you haven't done so before.
If this does not resolve the problem then it could be the adjusting motor, then you will have to pull the the side panels in order to apply a 6v dc to the motor and see if it moves smoothly, if not then replace motor.

Hi,

I looked into this thinking is must be a simple belt, or tention wheel, but these devices are much more complex than the average exercise machine. See the Recumbent selection here.

It appears that the tentioning device is a magnetic brake.
This would require that it be plugged into a power source and programmed to provide a desired tention.
I've never used one of these so I can't say what kind of programming options there are or where they are found.

Hope this helps.
Richard.
