Abstract:

This video reviews the SIG Plus M1 cycling computer and its accompanying SIG Plus C3 sensor, positioning them as an excellent, affordable option for amateur cyclists. The M1 computer features a 2.9-inch monochrome LCD with backlight, built-in triple-satellite GPS for fast and accurate positioning, and an impressive 30-35 hour battery life. It boasts ANT+ compatibility, allowing connection with various external sensors (like heart rate monitors, torque, and speed sensors) and can store 150 hours of ride data, which is easily synchronized with Strava via a dedicated phone application. The C3 sensor, designed for either speed or cadence measurement, is a lightweight, mode-switchable device. While the computer's display layout is fixed and there's a slight 1-1.5 second data delay, these are minor drawbacks for recreational users. The reviewer praises the robust build quality, clear display visibility, and overall value, contrasting it with much more expensive professional-grade devices that offer advanced features like navigation and customizable displays.

Exploring the SIG Plus Cycling Computer and Sensor

• 0:00 Introduction: The video focuses on the SIG Plus M1 cycling computer and the SIG Plus C3 sensor.
• 0:21 Unboxing & Accessories:
  • M1 Computer: Includes a simple handlebar mount, a rubber strap, a USB-C charging cable, and a detailed manual.
  • C3 Sensor: Comes with two rubber straps and two different profiled rubber pieces for attachment to either the pedal crank or wheel hub.
• 1:10 C3 Sensor Functionality:
  • Tiny, lightweight, and versatile.
  • Can measure either pedal cadence (when on crank) or speed (when on wheel hub).
  • Mode is selected by rotating the back cover.
  • Indicates current mode with an LED flash: green for cadence, blue for speed. Two sensors allow simultaneous speed and cadence tracking.
• 1:51 M1 Cycling Computer Features:
  • Display: 2.9-inch backlit monochrome LCD.
  • GPS: Built-in positioning supporting a three-satellite system for fast and accurate tracking.
  • Battery Life: Impressive 30-35 hours on a single charge, potentially lasting over a month for regular amateur use.
  • ANT+ Compatibility: Key feature enabling connection to various sensors (C3, heart rate from smartwatches, torque, other speed sensors).
  • Memory: Stores up to 150 hours of travel data.
  • Data Synchronization: Primarily via a phone application with automatic Strava synchronization.
• 4:04 M1 Computer Operation:
  • Controlled by three physical buttons at the bottom, each having short and long-press functions (total of six).
  • Functions include power on/off, route saving (start/stop), synchronization, lap measurement, and cycling through displayed data (current, maximum, average).
  • The "C menu" (accessed via button) allows basic settings like adding sensors (C2), setting wheel circumference (C3 for speed measurement), and time zone (C4).
• 5:01 Fixed Display Layout (Disadvantage): The data display layout is fixed and cannot be customized, leading to empty fields if corresponding sensors (e.g., torque, heart rate) are not connected.
• 6:24 Build Quality: Well-built with thick plastics, offering rain and impact protection via a rubber cover. USB-C port is for charging only; data transfer is app-based.
• 7:06 Phone Application (Sik Plus Fit App):
  • Displays weekly statistics and saved routes.
  • Provides map views of traveled routes and graphs for speed, elevation changes, and pedal rotation.
  • Seamless Strava synchronization once initially set up.
  • Minor Criticisms:
    • Birth date selection in the app is limited, not allowing dates before 1970.
    • Automatically assigns Chinese names to synchronized Strava routes, though this is easily changeable.
• 9:24 User Experience & Performance:
  • Visibility: Display is highly visible even in direct sunlight and without glasses.
  • Data Delay (Main Flaw): A 1 to 1.5-second delay in displaying real-time speed and sensor data. This is negligible for amateurs but a significant drawback for professional cyclists needing instant feedback.
• 11:29 Conclusion & Value:
  • Target Audience: Not suitable for serious professional cyclists who require instant data, advanced features (navigation, customizable color displays, segment tracking).
  • Ideal for Amateurs: Perfect for amateur cyclists who want to track performance, compare rides, and monitor general progress.
  • Affordable Price: Priced around 10,000-11,000 Forint, which is considered excellent value for its capabilities, especially compared to higher-end models costing 100,000-200,000 Forint+.
