Question About Keys Fitness Bicycle 550R
550r resistance levels...

The resistance levels all seem to be the same. I bought this bike used at a garage sale and level 1 is as hard as level 8 any suggestions?

1 Monitor display lights up with a humming noise, but none of the functions work. Is there a possible disconnected wire?
