Sunding Backlit Bicycle Speedometer, Wired SD563A or Wireless SD563C

You press the middle MODE button on the handlebar and the green backlit screen flips from speed to trip distance

The Sunding 563 series is a handlebar mounted cycling computer with a large LCD that shows speed in big digits and clock, ride time and trip distance on the lines beneath. Three buttons sit under the screen, with MODE in the middle, and the green backlight keeps the numbers readable when the light drops.

Pick the wired SD563A, where a cable runs from the wheel sensor to the unit, or the wireless SD563C, where the sensor talks to the unit without a cable. Both are English models in black, with an ABS body, a mounting bracket, a sensor with a magnet and a screen protector in the box.

Best for: Commuters, weekend riders and anyone who wants a simple speed and distance readout on a road, city or mountain bike.

Why It Works

A cycling computer should tell you what you need without a menu. Here speed sits in the biggest digits, the other lines hold the clock, ride time and distance, and the MODE button steps through the rest. The unit turns on and off automatically, and a low battery reminder tells you when to swap the cell.
