Pros

Stronger telematics and backend-control story than the BLE version
Vehicle-battery power reduces manual battery swaps
GPS plus motion detection are useful for fleet operations
Optional CAN bus motor immobilisation adds drivetrain-level theft deterrent on top of physical lock
Re-Lock says IoT data will be made available via API
ART certification supports EU fleet insurance acceptance
Thales secure element provides hardware-level cryptographic security

Cons

-Remote-open API endpoint is not yet available as of Re-Lock email on 2026-05-11
-Current customer flow is BLE: backend fetches session keys, app generates OTPs, and phone talks to lock
-No confirmed server-side remote-lock command; users lock manually by holding the lever
-Public site does not publish detailed IP or electrical integration specs
-Requires vehicle-power integration to realize the full feature set

Ideal For

Connected bike-sharing fleets

Integrated rental e-bikes

OEM programs needing backend unlock

Specs taken from the official Re-Lock solutions page on 2026-04-23, Chiel Bekker email replies on 2026-05-11 and 2026-05-13, and RE-LOCK Technical Sheets 2026 PCB PDF / product demo video provided in May 2026. Re-Lock confirmed Premium and Premium Plus support server-side remote unlock at the hardware/platform level, but current customers use the BLE session-key flow: Re-Lock Key Management Service provides session keys and the app generates OTPs over BLE. The API endpoint to control/open a lock is not yet available and is expected soon; IoT data will be made available via API. Optional CAN bus integration with e-bike powertrain controllers enables drivetrain-level motor immobilisation. Two ownership models are offered: capex purchase or monthly lease. 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 positions the Premium tier as the connected step-up from the BLE version. The official solutions page adds GPS, server-side unlocking, optional CAN bus integration, and crash or motion detection while drawing power from the vehicle battery.

Re-Lock confirmed on 2026-05-11 that Premium and Premium Plus support server-side remote unlock at the hardware/platform level, but current customer deployments use the BLE session-key flow. The API endpoint to control/open a lock is not yet available and is expected to be added soon.

The 2026 technical sheets identify the Premium IoT electronics as a 73.0 x 32.0 mm board with LTE Cat 1 bis / EGPRS, nano SIM, onboard GNSS antenna, Nordic BLE, 8-55VDC external power, internal LiPo backup battery, motion sensing, buzzer, stepper motor driver, and up to 4,000 stored position logs.
