Our take on the Bike Tail Light USB
The Bike Tail Light USB is a rechargeable rear light for bicycles. It charges via USB and mounts to the seatpost or rear rack. Riders value its brightness and long run time, but some find the mount fiddly and the charge port cover flimsy. It competes with other USB tail lights on brightness and battery life, though it lacks smart features like auto-brake or app control.
