Frequently Asked Questions
Is a U-lock enough for college campus security?
For most campus parking, a good U-lock with a 14–16mm shackle and a solid cylinder provides strong theft deterrence. Pairing a U-lock with a short cable for accessories makes it harder for opportunistic thieves; reserve premium locks for high-risk or overnight parking.
How should I carry a compact U-lock on my bike?
A frame-mounted bracket is the most convenient option — it keeps the lock secure and accessible without a backpack. If a bracket isn’t included, a small saddle or handlebar bag works. Choose a lock whose weight and shape suit how you commute.
What size U-lock do I need?
Measure the most common racks and anchors you’ll use. A 4 x 8 to 4 x 10 interior is the common compact range that fits most frames and allows you to lock frame and rear wheel to a rack. Longer shackles give more reach but often add weight and bulk.
