Review on 🔒 Secure Your Ride with BIGLUFU Bike Lock - Heavy Duty Folding Lock with 4 Keys, Mounting Bracket and Straps - Alloy Steel Foldable Design - 86cm Unfolding - 1.92 lbs - Ideal for Bicycles, Scooters, and Motorcycles by Roel Lebron

1. The lock comes with 5 keys none of which can be easily inserted to lock/unlock. The metal around the keyhole appears to be damaged or warped which also prevents easy access to the lock/unlock function.2. The lock case, which attaches to water bottle mounts for easy portability, only works on my old-school road bike frame due to the curvature of the attachment points. It can't be installed on every bike unless the water bottle cage tube is round and small diameter.3. Fastening straps are also useless.4. The lock rattles in the body when attached to the bike. Terrible product, save your money!
