The BI5 (back in 5) lock is a neat little bike lock that fits conveniently in your bag or back pocket.
Useful when security needs are low, when you’re away from your bike for just a short time, or perfect as a secondary lock for securing your front wheel. Not as bulky as a common U-lock, but more secure than a cable lock. Its sleek design and colour combinations will make your bicycle toolkit just a little bit more stylish!
Take it wherever your bike takes you.
Register your keys so that if you ever lose them a new set can be made.
