Assembled per instructions. The exercise bike does not run smooth like in the video Not sure what needs to be adjusted. Turned tension on low still hard to peddle smooth without that hesitation of feeling stuck. I'm a cardiac patient was suggested to get a stationary bike, I don't want to get a heart attack from this stress of working this equipment. One would think that it would be set at the factory. Lack of Customer support. Please help Gail Grutzius User's recommendation: sturdy exercise bike, the console needs to be removed to put the batteries in. Poor housing for battery. takes or more hours to build and bring your own tools the ones provided really don't work well.
