I always make sure dabz is ready before I step on and he has both feet on the floor and holding onto the bars to steady the bike, only a couple of times have I not made it first time but touch wood we've never fallen over or anything dramatic! When it is almost dropped its because he's not ready

Hope your gf will enjoy the sports bike, it's very different being sat higher than the rider! The more times she gets on and off the better you'll both get at it ��
