I ride a 636 and Im 5'6.....5'7 on a good day lol.....I can barely tippy toe the thing. Usually I come to a stop with my right foot on the brake and left foot FLAT FOOTED on the ground....Since the bike is so light she SHOULD be able to support its weight with one leg....you just need to get over that feeling that it will tip over if you don't have two feet on the ground. Please don't lower it
