This is a simple GPS speedometer with a few other features! I've tested it on my bike and it is accurate and works well enough for my inspector to pass it on the inspection! No magnets or calibration required! Just turn it on and go! Has a light sensor to turn on a backlight at night! Will mount to any size bar easily with included mounts. It also recharges using USB C and it lasts a long time on a single charge!
