SPIDER Automation | WYZ23837 Waterproof Wireless Bicycle Speedometer & Odometer | Multifunction Backlit LCD Cycling Computer
The WYZ23837 Waterproof Wireless Bicycle Speedometer & Odometer is a multifunction cycling computer designed to provide essential riding information through a compact handlebar-mounted display. It combines real-time speed monitoring, cumulative odometer measurement, individual trip-distance tracking, riding-time functions and ambient temperature measurement in one unit.
Its wireless wheel-speed sensing system uses a wheel magnet and wireless sensor to detect wheel rotation and transmit speed-related data to the meter body. This removes the need for a wired signal connection between the wheel sensor and the display. The large backlit LCD supports visibility in low-light conditions, while the supplied base bracket and control button provide a convenient handlebar installation arrangement.
Product Overview & Functional Design
The WYZ23837 is designed for cyclists who want multiple riding measurements without installing separate instruments for speed, distance and travel-time monitoring. Its display continuously presents current speed, while dedicated measurement modes provide access to total mileage, single-trip distance and time-related information.
The integrated ambient temperature function adds environmental information to the cycling display. Its waterproof construction is intended for outdoor bicycle use, including exposure to rain and splashes. The wireless sensor arrangement also helps keep the bicycle installation free from a long signal cable running between the wheel and handlebar display.
Technical Features & Functional Characteristics
- Continuous Speed Monitoring: Keeps the current bicycle speed visible during operation, with readings available in kilometres per hour or miles per hour.
- Large Backlit LCD: Provides a clear display interface and supports reading information in reduced-light riding conditions.
- Wireless Speed Detection: Uses a wheel magnet and wireless sensor to detect wheel rotation and transmit speed data to the meter.
- Cumulative Odometer: Tracks total accumulated distance through ODO mode, with the displayed value returning to zero after reaching its maximum count.
- Single-Trip Distance: Records individual ride distance through DST mode.
- Trip Riding-Time Function: Provides TTM measurement for the accumulated riding time of an individual trip.
- Travel-Time Function: Includes a separate RAT time measurement mode.
- Ambient Temperature Measurement: Displays surrounding temperature in Celsius or Fahrenheit.
- Handlebar Control Arrangement: Uses a base bracket with an integrated wire control button for convenient access to meter functions.
- Waterproof Construction: Designed for outdoor cycling conditions where rain and splashes may occur.
Display Functions & Measurement Modes
The WYZ23837 provides multiple measurement modes for monitoring bicycle speed, distance, riding duration and surrounding temperature.
- Current Speed: Continuously displays the bicycle’s current speed, with a maximum reading of 99.9 km/h or mph.
- ODO – Total Distance: Displays cumulative mileage from the odometer’s counting history. Its range extends from 0 to 99,999 km or miles. The displayed value resets to zero after reaching the maximum count.
- DST – Single-Trip Distance: Displays the distance travelled during an individual trip, with a range of 0–9,999 km or miles. The reading returns to zero after reaching its maximum limit.
- TTM – Trip Riding Time: Records the total riding time for one trip, with a stated range of 0–9,999 hours.
- RAT – Travel Time: Provides a separate travel-time measurement function, with a stated range of 0–9,999 hours.
- Ambient Temperature: Measures the external environment temperature over the stated Celsius range and also supports Fahrenheit readings.
Wireless Wheel-Speed Sensing System
The wireless speed-detection arrangement consists of a wheel magnet and wireless sensor. The magnet is fitted to a rotating wheel component, while the sensor is positioned nearby. As the wheel rotates, the magnet passes the sensor, allowing wheel movement to be detected and speed-related information to be transmitted to the display.
Correct sensor positioning and wheel-size configuration are important for dependable readings. The wheel circumference setting must correspond to the actual wheel and tyre combination so that the meter can calculate speed and distance from detected wheel rotation.
Mounting & Mechanical Installation
The meter body is designed to fit onto the supplied base bracket for handlebar installation. The wireless sensor and wheel magnet are installed near the wheel to establish the speed-detection arrangement. A tie strap is included to assist with securing the sensor assembly.
- Display Mounting: Secure the base bracket to a suitable handlebar position where the LCD can be viewed conveniently.
- Sensor Positioning: Install the wireless sensor near the wheel magnet’s path, following the positioning guidance in the instruction manual.
- Magnet Alignment: Attach the magnet to a rotating wheel component so it passes the sensor consistently during wheel rotation.
- Sensor Securing: Use the supplied tie strap to secure the sensor in its intended position.
- Wheel Configuration: Set the wheel circumference according to the bicycle’s actual wheel and tyre size for accurate speed and distance calculations.
Applications
The WYZ23837 is intended for compatible bicycles where riders require a multifunction display for speed, mileage, trip duration and ambient temperature monitoring.
- Mountain Bikes: Supports speed and trip monitoring during recreational and trail cycling.
- Electric Bicycles: Provides an independent wheel-based speed and distance display for compatible e-bike installations.
- City Bicycles: Helps monitor speed and accumulated mileage during everyday urban travel.
- Commuter Bicycles: Provides trip-distance and travel-time information for regular journeys.
- Fitness Cycling: Supports basic ride monitoring through speed, distance and riding-time measurements.
- Recreational Cycling: Gives casual cyclists access to essential riding information in one display.
- Touring Bicycles: Helps track cumulative mileage and individual trip distance during longer rides.
- Replacement Cycling Computer: Can be used as a replacement display where the bicycle’s mounting arrangement and wireless sensor installation are compatible.

Connection & Operating Recommendations
Correct wheel configuration, sensor alignment and display mounting are important for dependable speed and distance readings. Follow the supplied instruction manual for the model-specific setup and operating sequence.
- Configure Wheel Circumference: Enter the correct wheel circumference for the bicycle’s wheel and tyre combination. An incorrect setting can affect speed and distance calculations.
- Align the Magnet and Sensor: Position the wheel magnet so that it passes the wireless sensor consistently as the wheel rotates.
- Secure the Sensor: Use the supplied tie strap to prevent unwanted movement of the sensor during normal riding.
- Check Wireless Detection: Rotate the wheel after installation and confirm that the display responds to wheel movement.
- Mount Within Easy View: Position the meter so its display can be read comfortably without obstructing steering or access to bicycle controls.
- Select the Preferred Units: Configure the speed and distance units according to the rider’s preference and the meter’s operating instructions.
- Observe Temperature Readings: Allow the unit time to respond to changes in surrounding temperature, particularly when moving between environments with substantially different temperatures.
- Protect the Electronics: Although the product is described as waterproof, avoid pressure washing or prolonged immersion unless its specific water-resistance rating permits it.
