I bought this as a replacement for same light which I misplaced (senior moment). Used in flashing mode I can get well over 100 miles of riding on one charge ( multiple rides of 32-46 miles. Probably could go much further. Easy to charge. Solidly built. Ive ridden for over 40 years and have developed my favorites. For lights it is always Light and Motion.
I have a Giant road bike and an Lectric Xpremium eBike. The light on the eBike was not working from the the time i got it. Friend of mine has same bike and she has the LED which is brighter, but this light is so much stronger. With a few twists of the lock in screw and it pops out for charging. lasts a good while, went 120 miles with it flashing and continued for entire ride which was 121 miles. Light is awesome
