There are ways you can improve the shape of your abs and that is by balancing your exercise routine. Bicycle is good but you may also want to try crunches and pull-ups (the ones you pull your knees up as well) to make sure your chest muscles and the muscles beneath your armpits don't start looking unflattering. If all else fails, use a roller. Granted you won't be able to eat anything for a while but at least you stomach will be flattened and you can start again.
