Problems and challenges

Abstract

Owning a fantastic bike is a cool thing, but when someday you walk out your classroom and find out that the wheel or seat of your bike is missing, that is not cool at all. The construction design of modern bicycle caused it very easy to be disassembled. Adding extra lock could reduce the chance of bicycle parts, especially front wheels and seats, being stolen. However, using multiple locks also increases time taken to unlock the bike, which is inconvenient.
