Frequently Asked Questions
How long should a folding bike lock be when unfolded?
Aim for a lock that opens to at least the circumference needed to loop through the frame and a wheel plus an immovable object; many compact folding locks offer 29–43 inches (approx.) of circumference. Choose the length that fits the racks and posts you use most often.
Are folding locks as secure as U-locks or chains?
Folding locks can match or exceed many U-locks and chains when they use hardened plates and quality rivets; look for heavy-duty materials and strong cylinders. For the highest risk situations, a certified heavy-duty lock or combining a folding lock with an additional secondary lock provides extra deterrence.
What mounting option is best for carrying a folding lock?
A stable frame mount or purpose-built case that eliminates rattle is best — it keeps the lock accessible, prevents loss of parts and makes it more likely you’ll bring the lock on short trips. Check that the mount fits your frame and that straps or screws match your seat tube or bottle-cage area.
