I spent a lot of time trying to find a fully that wouldn’t bob when I peddled it. A good bike shop will help you adjust the rear shock. Also a lot of rear shocks don’t have a lock out. Try locking your fork when going up a steep hill. I found that my fully makes hill climbing a lot easier because the rear wheel stays on the ground more. Also, if you have the stock tires on the fully, you may want to upgrade. Tires make a huge difference.
