You get the same feeling as riding a real bike, ie; more force required in the pedal pushing down position and less force on the upstroke. No assembly or quality issues.
I compared both the Teeter Hangups and the Gravity 4000 in a local sporting goods store. Without question the 4000 is way more comfortable, every bit as well designed and sturdy, very easy to assemble and less that half the price, . Also, no problems with packaging. Item was delivered completely intact. With the height adjustment set correctly the incline is controllable with movement of hands and arms.
