Bike radar: choosing by “Detection range”

Detection range decides how early a warning arrives before a vehicle gets close. Most units tracked here sit in the shorter range and already cover everyday riding conditions, while the longer range option is less common in this lineup but tends to rate higher. Pick the longer range mainly for fast or busy roads, where extra warning time matters most.
