Details

• [SECURE METAL LOCKING CLAMP] Equipped with a metal locking clamp, it fits standard-diameter bicycle handlebars. The installation process is simple, and it resists loosening or slipping even on bumpy trails. With excellent fastening performance, it is suitable for both daily commuting and off road riding, ensuring your device stays put no matter the terrain.
• [BATTERY FREE MECHANICAL DESIGN] It adopts a purely mechanical transmission structure, requiring no batteries, which eliminates the hassle of frequent battery replacements and the frustration of power failures. It operates stably even in complex outdoor environments like intense sunlight and low temperatures, ensuring greater reliability for long distance rides. The vintage style dial also adds a highly atmospheric look to your bike build.
• [COLOR CODED SAFETY ZONES] The dial uses green and yellow color zones to delineate speed ranges: the low speed safe zone is marked in green, while the high speed warning zone is in yellow. This allows you to instantly identify your current speed range even in bright outdoor light, making it easier to control your pace and avoid overspeeding for a safer cycling experience.
• [DUAL SCALE DISPLAY FOR INSTANT DATA] The dial features dual scales with a maximum speed reading of 60 km/h and RPM markings, allowing riders to check both riding speed and wheel rotation speed at a glance. One quick reading provides two types of cycling data to meet different riding reference needs, making every ride more informed and efficient.
• [BUILT IN MECHANICAL ODOMETER] The dial comes with a built in mechanical odometer counter that records total cumulative mileage. This makes it easy to track your monthly and annual riding distance, helping you monitor training progress and plan your bicycle maintenance schedule, perfectly meeting the recording needs of fitness rides and long term cycling goals.
