According to my experience, this flashlight is a must-have for any cycling enthusiast.The adjustable focus feature ensures that you have the perfect beam size for any situation while the rechargeable battery means you won't have to keep buying disposable batteries. The flashlight is also resistant to water, dust, and shock, giving me the confidence to take it on any ride. The only downside is that it may be a bit heavier than other flashlights, but the bright light output makes up for it..See full review
