LAS VEGAS – Lattis unveiled the Ellipse Smart Bike Lock at CES last week. In addition to being app-controlled and having a programmable combination lock, this bike lock is solar powered. That makes batteries a non-issue as long as the device sees at least one hour of sunlight per week of usage. It has a built-in accelerometer which the app harnesses for crash alerts with HPS coordinates it can send out to a designated contact. The accelerometer is also used for theft detection alerts. Another nifty feature is the ability to give a friend access through a one-time code you can send out from the app. The shackle is made from chromoly steel, and the lock is substantial. I liked the fit and finish, and the “smart” functions seem to be smart, rather than an attempt to merely bolt an app onto a lock. The device is priced at US$199, and it’s available now.
