Specs taken from the official Re-Lock solutions page on 2026-04-23, then updated from the RE-LOCK Technical Sheets 2026 PCB PDF and product demo video provided in May 2026. Re-Lock advertises a patented digital lock mechanism as a market differentiator. Two ownership models are offered: capex purchase or monthly lease. Known fleet customers include ING, Roetz, Over-Amstel Boerderij, SURE mobility, and Poldar. Nazza micro-mobility software is a named SDK integration partner. Manufacturing origin is the Netherlands. Re-Lock (Chiel Bekker) confirmed commercial terms on 2026-05-13: standard MOQ is 1,000 units (a 100-unit pilot is possible if stock allows); a special 2-sample pilot kit covering one BLE plus one Premium unit is available for €100 with operator-supplied UPS/FedEx account. Lead time is 10 weeks per order (confirmed at quote time; quotes valid 30 days). Premium pricing includes a GSM SIM with 30 MB of data per month for 3 years; bring-your-own SIM has no specific network requirements. US import/certification specifics are still pending forwarder reply. Re-Lock will be unreachable 2026-05-14 through 2026-05-18 for the Dutch national holiday.

About This Product

Re-Lock presents the BLE model as the entry point in its smart-lock range for sharing and rental operations. The official solutions page states that the BLE version opens and closes over Bluetooth, uses a replaceable battery, and fits around almost any tire up to 70 mm.

Re-Lock also emphasizes integration with either its own system or compatible fleet management platforms. That integration-first positioning is why the BLE variant belongs in the catalog despite the relatively light public product page.

The 2026 technical sheets add the underlying BLE PCB details: a compact 73.0 x 30.0 mm board, Nordic nRF52832 radio, BLE 4.0 / proprietary 2.4GHz support, up to 30 m short-range operation, 3D accelerometer, buzzer, stepper motor driver, and OTA firmware/configuration updates.
