In daily use

Mounting the Curve takes only a moment: stretch the durable silicone strap around your seatpost and you are ready to ride. The curved body hugs the post, reducing the risk of snagging on bags or clothing, while the soft-touch button lets you cycle through modes even with gloves on. The battery indicator glows to show charge status, so you will never be caught off guard. Whether you ride through busy intersections or unlit paths, the wide beam ensures motorists and pedestrians notice you early.
