The name Safety Cycle brings back some memories--not all pleasant. Back when I went High School they just about the only game in town (or at least that part of town). They were generally rude, obnoxious and condescending. It because of them that I finally decided to learn how to fix my own bike.
FWIW, there is one one those "bike kitchens" not too far from Safety Cycle. It is licated near LA City College. you can borrow their tools for a small donation and do your own wrenching.
