Lighting options are very good. Charging while lighting option is the missing.
Light output is sufficient for night rides. However the handle bar mounting system has a flaw in design. Some vibration on the road and the light falls off the bike. There are 2 tabs on the mount which gets locked in to the light. The release handle vibrates on bumpy surfaces and the light falls off. Happened twice for me and was fortunate that someone riding behind picked it up and gave it to me.
Light Build - 5/5
Mount - 4/5 (clip gets easily detached, on rough patches light may come loose & fall)
Brightness - 5/5
Battery backup - 3/5 (runs out pretty quickly on high mode, medium mode is perfect. Not for bikepacking trips)
Charging - 3/5 (doesn't support fast charging, will take some time, so, plan ahead)
Reliability - 5/5 (never failed on me)
Versatility - 4/5 (is a bit bulky but pretty small in size)
Using this light since 09/21
Bought two of these from BOTS, arrived early. Both lights perform well and hold their charge well. The lights are incredibly well built and mount securely, with one of these lights your bike outputs more light than most motorcycles, with two of these you begin to output light that is comparable to buses and trucks or large cars, your bike definitely outshines most small cars with two of these. Love these lights by niterider, and also thanks BOTS for timely delivery.
