TMD’s keyless bike lock is a $280 solution to a $60 problem

A $280 bike lock, the TMD Chain Lock, is being marketed for high-end e-bikes despite being overpriced. It features a hardened steel chain, Bluetooth sensor, and motion alarm. This lock is worth considering due to its ART-2 certification and insurance-friendly features. It's a solution to a relatively inexpensive problem. Engineers may want to consider alternative, more affordable options.
