I've racked up 3000+ miles riding up and down the hills in SF (530 vertical feet over 3.7 miles). 4 falls, 1 going too fast downhill and overcharging the battery (dislocated shoulder), 1 crossing tracks perpendicular slowly, and twice slipping on wet metal. Except for the first time I only managed to get banged up.

Take safety seriously and remember that things can go bad any time, so go slow (but not too slow) when it's riskier. Knowing how to foot break and fall safely are also musts.
