Input:
It fits well on my Optibike.  Loud enough to be useful to warn people on the path.  In black it looks good on the black handlebars. Mostly indicates north. It swings when I apply power to the motor and this is expected given the laws that apply to electricity. I just make sure that I check the direction when the power is off.
