At present, only displays for Bee Challenger and Bee Pathfinder series have password setting. By setting the password, you can secure your bike better. To set the password, you need to pay attention to two things. First, if the password is not entered or entered incorrectly within 30s of the countdown, the meter will automatically shout down. Second, if you forget the password, you can't reset it by yourself and the only way to solve the issue is to contact us to replace the display (To replace the display for forgetting the password is not covered in the warranty, so customer needs to pay for the cost for the new display by themself).
