The rear suspension is adjustable. If the ride is too harsh, try adjusting down one position on each rear shock for a softer ride. There are 5 positions on the shocks. Most of the bikes come set up on position #2. I weigh 160 and find any position higher than #2 too firm for me. Even when my wife rides I keep it in that position because she won't ride unless the ride is soft - we both have back problems and hard bumps hurt.
If your complaint is that the ride is too soft, try going up one or two positions.
