Specs taken from Sentinel M60 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. Among the Sentinel range, the M60 is the only model with an embedded eSIM, which means data plans ship pre-provisioned and operators avoid juggling local-carrier SIM contracts across EU borders. Its compact 168.7 x 144 x 38 mm / 1.0 kg form factor and IP67 rating target standard-tire urban e-bikes and pedelecs in corporate, hotel, residential and short-term rental fleets. Sentinel's white-label customer list includes Blue-Bike, BASF Antwerp, Mobit, YUST, Shell, and PBSC / Lyft Urban Solutions (the latter for the 8,500-unit BiciMAD Madrid relaunch). A Premium subscription with the first year free covers connectivity and platform access; fleet pricing is negotiated via RFQ.
About This Product
Sentinel positions the M60 as a compact keyless smart lock with GPS, RFID card access, Internet connectivity, and solar charging support. The official page highlights app, key fob, ID card, and remote backend unlock workflows.
Integration is still a core part of the product family. Sentinel states that all of its lock hardware can connect to the Sentinel fleet platform or third-party platforms via API, which keeps M60 inside a real fleet integration path rather than a self-contained consumer app.
