Specs taken from Sentinel cable-lock hardware page plus Sentinel Smart Lock API page on 2026-04-23. Sentinel is a Belgian company (HQ Corda Campus, Hasselt; founded 2017); sentinel-tec.com is the B2B / OEM brand and Zingi (zingi.solutions) is the bike-share spinoff. Within the Sentinel range, the Smart Steel Cable Lock carries the largest battery (10000mAh, roughly 2x the S90 and 3x the M60) and the most flexible form factor - the cable wraps cargo trike frames, e-scooter handlebars, trailer hitches, rental kayaks, golf carts, and other ground-tied assets - making this the SKU Sentinel positions explicitly for REST-API-driven asset tracking on mixed, non-frame fleets. Sentinel's white-label and fleet customer list includes Blue-Bike, BASF Antwerp, Mobit, YUST, Shell, and PBSC / Lyft Urban Solutions (which deployed 8,500 S90 units for the BiciMAD Madrid bike-share relaunch). A Premium subscription with the first year included free covers connectivity and S.Cloud platform access; fleet pricing is negotiated via RFQ.
About This Product
Sentinel describes this product as a smart steel cable lock with real-time positioning and comprehensive connected functions. The official page calls out GPS, Bluetooth, RFID, Internet connectivity, solar charging, and a seat-post mounting bracket.
Just like the rest of Sentinel's hardware family, the cable lock is positioned for use with the Sentinel fleet platform or third-party platforms via API. That makes it a legitimate integration product rather than a generic consumer cable lock with an app.
