I use this light kit for commuting and trail riding on my MTB bike; I like the helmet mount option as well; great to charge my phone; highly recommended!
The best way to use all PWR lights in my opinion, the smaller profile makes look stealthy. It's would be nice if the kit also came with a GoPro style mount so people could mount it on a dual sided mount.
It's a very bright light. I have it fit to my GoPro mount which is attached to the bottom of my QuadLock and that is a rock solid mount. I didn't think the actual PWR Mountain Kit mounts were as nice. I have a Hybrid bike.
It offers a good light for my gravel bike while touring. It has multiple light settings to allow the rider to see and be seen on the road or trail. It can also double as a power bank to recharge other devices. I plan to recharge the battery with a solar panel while touring.The kit offers several mounts (helmet, handle bar, front fork).
The Mountain Kit was easy to install on the bike and helmet. It is not reasonably light, but the solid aluminium construction feels sturdy and secure with all the kit provided. It also has fantastic brightness. The medium-level (last about 8 hours long) setting is bright to use on country roads with no street lights and freeways. I've gone a few Audax rides through the night with it so far been impressive.
