Overview and First Impressions
The VDO M2.1 WL is a wireless cyclocomputer with a simple yet functional design. It features two red buttons, one on top and one on the bottom, each acting as forward and back controls. The display shows essential cycling data in an easy-to-read format, making it ideal for casual riders or those seeking a straightforward cycling companion.

The unit itself is compact and unobtrusive on the handlebars. It’s branded clearly with the M2.1 logo, which is visible on the screen even during operation. The overall aesthetic is clean and modern, without unnecessary embellishments.

Features and Functionality
The cyclocomputer displays key metrics such as current speed, trip distance, average speed, maximum speed, ride time, and total distance. It also tracks calories burned and total ride time since the last reset. All this information is presented in a clear and concise manner, making it easy to monitor progress.

The use of two buttons, while seemingly simple, provides intuitive control over navigation through the various metrics. The large number display for current speed is a particular highlight, making it easy to read even at a glance.

Sensor and Battery
The wireless sensor is sleek and attaches easily to the bicycle using zip ties. Its design complements the overall minimalistic approach of the cyclocomputer. The device runs on standard watch batteries – two in total – one for the computer and one for the sensor.

This simple battery setup is both convenient and cost-effective. Replacing the batteries is straightforward, avoiding any complicated charging systems.

Performance and User Experience
The cyclocomputer performs reliably. However, it has one minor drawback: the device needs a manual button press to initiate tracking when starting a ride. Once activated, it provides accurate and consistent data without further interruptions.

While this initial activation step might be slightly inconvenient, the overall performance and accurate data make up for this minor issue. The large digits on the display and the straightforward menu navigation further enhance the user experience.

Pricing and Final Verdict
The VDO M2.1 WL is priced competitively within its category, usually around $35-$40 for a new unit. Used units might be available at even lower prices. This makes it an attractive option for budget-conscious cyclists.

While not packed with advanced features, the VDO M2.1 WL is a reliable and straightforward cyclocomputer that delivers essential cycling data accurately. The minor inconvenience of manually activating the tracking at the start of each ride is easily outweighed by its overall performance and value for money. It’s a great entry-level option for those new to cycling computers or looking for a simple and dependable device.
