Best-Selling Hub Motor with Smarter IoT System

The BAFANG 48V 500W RM G020.500.DC Rear Hub Motor has long been one of VARSTROM's best-selling hub motor kits and the preferred choice for many OEMs, distributors, and bulk buyers. To bring this proven platform to the next level, we've upgraded the controller and the display for an optional IoT system (subscription required), delivering enhanced smart connectivity for a more complete riding experience.

  • More accurate real-time GPS positioning
  • Advanced remote monitoring and control
  • Enhanced anti-theft protection with intelligent security features
  • Instant alerts for bike position
  • A smarter and more connected e-bike experience

Hardware Upgrades That Power a Smarter Ride

A better riding experience starts with better hardware. To deliver more intelligent features and a seamless connected experience, this system has been upgraded with a new generation of IoT hardware, including:

Hardware Upgrades for C60X IOT Display
  • Built-in Gyroscope for enhanced motion sensing
  • GNSS Positioning Module for accurate global location tracking
  • 4G Cat.1/NB-IoT Communication Module for reliable cellular connectivity
  • Cloud Platform for real-time data management and connected services

Together, these hardware upgrades enable a wide range of smart features, including real-time tracking, remote monitoring, intelligent anti-theft protection, and a more connected riding experience.

True Remote Control, Powered by 4G Connectivity

Unlike Bluetooth, which only works within a limited range, the VARSTROM IoT system uses 4G Cat.1/NB-IoT connectivity to enable true remote access from virtually anywhere. Key remote features include:

True Remote Control Function for BAFANG 48V 500W RM G020.500.DC Kits with IOT Controller System
  • Remote System Activation
    Turn on the e-bike system remotely through the mobile app using the cellular network—no Bluetooth range limitations.
  • Real-Time Location Sharing
    View and share your bike's location in real time, making it easier to locate your e-bike whenever needed.
  • Remote Power-On Password Management
    Create, update, or share the power-on password remotely, allowing authorized users to access the e-bike without requiring physical setup.

Multi-Layer Anti-Theft Protection

Powered by a combination of GNSS positioning, 4G connectivity, and a built-in gyroscope, the VARSTROM IoT system provides intelligent, real-time security for your e-bike. Key anti-theft features include:

Anti-Theft Protection Function for BAFANG 48V 500W RM G020.500.DC Kits with IOT Controller System
  • Motion Detection Alerts
    The built-in gyroscope detects unexpected movement or vibration and instantly sends a notification to your smartphone.
  • Remote Power Button Lock
    Disable the physical power button remotely through the app, preventing unauthorized users from turning on the system directly from the bike.
  • Geofence Alerts
    Create a virtual riding boundary in the app. If the e-bike moves outside the designated area, you'll receive an instant alert on your smartphone.

Ride Freely — No Subscription Required

The VARSTROM IoT system is completely optional. A subscription is only required if you want to access advanced smart features such as remote connectivity, GPS tracking, and intelligent anti-theft functions. Even without an active subscription, your e-bike will continue to operate just like a standard system, with all essential riding functions available. Standard features include:

Free Standard Function for C60X IOT Display
  • Speed unit selection (km/h or mph)
  • Speed limit adjustment
  • Quick speed limit shortcut (25km/h)
  • Wheel size configuration
  • ODO (Total Distance) & TRIP data
