This is elementary, but I live in a very hilly area. Often I have to stop at a stop sign or traffic light where the hill is very steep. I always feel uneasy that I might loose the bike when I take off. I always hold the position with the front brake, but I am always afraid that I might not give enough throttle and kill the engine, or too much and spin out. I believe this is just a phobia, but would like some comments. Thanks.
