I bought this months ago. I am a teacher, so I just installed it on my bicycle this summer. It will work and then just stop working for a while. When it decides to begin working again, it will switch speeds at a range not capable by me (or any other person.) It will read 12 mph and then go immediately to 18 mph. It was installed according to the instructions and works most of the time. I ride on paved surfaces just trying to get back into shape. It is not like vibrations are a problem. Money wasted.
