I\u2019ve seen lots of so-called \u201csmart\u201d bike locks over the years, but none so far could justify the added cost. A newcomer that got its start securing ATMs for banks is trying to change that. There\u2019s nothing wholly unique about the TMD Chain Lock<\/a>, but the combination of materials, performance, and insurance-friendly ART-2 certification makes it worth considering.<\/p>\n<\/div>\n

TMD\u2019s first bicycle lock combines a Bluetooth proximity sensor and motion alarm with a slender core of hardened steel chain wrapped in a soft and lightweight sleeve of high performance Dyneema and Kevlar fibers. That makes this lock tough, yet flexible enough to conveniently wrap around your seat post when cycling. TMD also designed the keyless lock to be shareable with friends and family, and capable of withstanding shock, rain, dust, and extreme temperatures. That makes it highly suited to city bikes parked outside and ridden all year long.<\/p>\n<\/div>\n

I like the TMD Chain Lock I\u2019ve been testing, but spending \u20ac249 (about $283) on something that typically costs far less is a big ask.<\/p>\n<\/div>\n
