Detection range determines how much warning you get before a vehicle approaches from behind. Most models tracked here cover the shorter range, which suits city and suburban riding, while the longer-range radars are less common but rate noticeably higher in this lineup. Pick the longer range if you mostly ride on fast, open roads where extra warning time matters.
