Bike lights are the essential accessory for every ride, whether day or night. The Cateye Rapid Mini provides a good balance between visibility and cycle time, features a durable case and a Brompton-designed rear bracket, this allows the lamp to mount under the Brompton saddle - an ideal solution for providing a secondary rear light on our special folding bike (prevents obstruction when lowering seatpost on a folded position of a Brompton’s bike). The lightweight Cateye Rapid Mini has four lighting modes; it offers a constant, flashing, rapid-flashing, and pulse mode to help keep you visible to other road users. This mini rear lamp can handle bumps and drops, light spray and rain from road use. Has a long battery life of up to three hours in constant mode, up to five hours on rapid mode, up to 20 hours on pulse mode and up to approximately 30 hours on flashing. This light is rechargeable via the included micro-USB cable.
