I purchased this item new 4 years ago and used it for about a year, but I'm selling it because I no longer need it. There are no issues with its operation. The included accessories are the saddle mount and remote control only. Please understand that there are no other accessories. It also has a brake light sensor function. It also has a security function, so I think it will protect your important bicycle. (The security sound is 120dB, so it's quite loud) This product is used. Please refrain from purchasing if you are concerned about the condition.
