I just started riding (road) exactly 2 mos ago. I will not go on my bike without one. I've fallen twice (and a few near misses) learning to use my spd pedals. I've never hit my head but I really don't mind wearing a helmet. Mine is quite comfy.

My husband also has a motorcycle. Neither he nor I would ever ride it without helmets even though they are not mandatory. Why risk it, on a bike or motorcycle?!
