SC350MG
Queclink SC350MG — LTE Cat M1 e-bike GNSS tracker reading battery and ECU data via CAN/UART. Official Queclink UK distributor.

Queclink SC350MG — Purpose-Built LTE Cat M1 E-Bike Tracker with ECU and BMS Data Reading
The Queclink SC350MG is a genuinely unique product — a compact LTE Cat M1 GNSS tracker designed from the ground up specifically for electric bikes. Where standard vehicle trackers simply provide GPS location, the SC350MG goes far deeper — communicating directly with the e-bike's vehicle controller, instrument cluster and Battery Management System via CAN or UART ports to read critical operational and battery data that e-bike operators and fleet managers need to manage their assets intelligently.
By reading battery voltage, remaining capacity, battery temperature, charging state, mileage, torque and component diagnostic information directly from the e-bike's own systems, the SC350MG transforms a standard GPS location device into a complete e-bike intelligence platform — enabling predictive maintenance, real-time battery monitoring, remote immobilisation and smarter fleet operations for e-bike sharing services, rental operators and commercial e-bike fleet managers.
As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the SC350MG directly from our London warehouse — with trade pricing available for e-mobility operators, telematics service providers and resellers.
Key Features
CAN and UART ECU and BMS data reading — communicates directly with the e-bike's vehicle controller and Battery Management System to read battery voltage, remaining battery capacity, battery temperature, charging state, mileage, torque and component diagnostic information
LTE Cat M1 and NB with 2G fallback — global IoT network connectivity for real-time e-bike data transmission and tracking across UK and international networks with automatic 2G fallback
Wide 8-60V power input — specifically designed for e-bike electrical systems, supporting the wide voltage range of e-bike batteries without requiring additional converters or adapters
BLE connectivity — supports Bluetooth Low Energy wireless unlocking, allowing riders to unlock their e-bike wirelessly via a smartphone app or BLE device
Vibration detection for anti-theft — built-in vibration sensor detects unauthorised movement or tampering and triggers immediate alerts to the fleet management platform
3-axis accelerometer — detects motion, impact and orientation for comprehensive anti-theft and crash monitoring
Real-time GPS positioning — GNSS tracking with GPS and additional constellation support for accurate real-time e-bike location across urban and rural environments
Remote immobilisation — digital output enables remote disabling of the e-bike via the fleet management platform
IPX5 water resistance — splash and weather resistant for reliable outdoor operation in all UK weather conditions including rain
Geofencing — configurable zone alerts when e-bikes enter or exit defined operational areas such as parking zones, exclusion zones or depot boundaries
Low battery warning — automatically alerts when battery level falls below a configured threshold for proactive battery management
Malfunction alarm — transmits diagnostic fault alerts when component issues are detected via the ECU or BMS connection
OTA updates — remote firmware and configuration management without physical access to the device

Frequently Asked Questions
What ECU and BMS data does the SC350MG read?
The SC350MG reads battery voltage, remaining battery capacity, battery temperature, charging state, mileage, torque and component diagnostic information directly from the e-bike's controller and Battery Management System via CAN or UART ports. The exact data available depends on the specific e-bike model and controller compatibility. Contact us for guidance on compatibility with your specific e-bike brand.
What is the difference between CAN and UART on the SC350MG?
CAN — Controller Area Network — is the standard communication protocol used on many e-bikes for controller to system communication. UART — Universal Asynchronous Receiver Transmitter — is an alternative serial communication protocol used on some e-bike controllers and BMS systems. The SC350MG supports both, giving it broad compatibility across different e-bike brands and controller types.
Can the SC350MG remotely immobilise an e-bike?
Yes — the SC350MG includes a digital output for remote vehicle immobilisation, allowing fleet managers to disable an e-bike remotely via the fleet management platform in the event of theft, overdue rental or other scenarios requiring immediate vehicle control.
Does the SC350MG support wireless unlocking?
Yes — the SC350MG supports BLE connectivity for wireless e-bike unlocking, allowing riders to unlock their e-bike via a compatible smartphone app or BLE device — a key feature for shared and rental e-bike deployments.
Can I buy the SC350MG in bulk from Tracking Hardware UK?
Yes — we supply e-mobility operators, telematics service providers and resellers across the UK and internationally. Volume pricing and trade accounts are available. Contact us for a bulk quote.
Does the SC350MG support driver identification?
Most hardwired Queclink vehicle trackers, including the SC350MG, can be paired with iButton driver ID readers so every journey is logged against a driver. Contact Tracking Hardware UK to confirm the right reader and configuration for your installation.
