Question: how is the helmet mount?
Document: Came with a helmet mount as well but I haven't tried that yet.
The light mounts up to either your bars or your helmet with the additional helmet mount provided. Get this light. You will not be disappointed.
Road Bike or if its a larger diameter off-size mountain bike it wouldn't fit). He said engineering is working on it for handlebars and seat posts, but as of right now, the only option I have is helmet mount.
This light is bright, light and ready for night. I keep a mount on a helmet, one on the bike and I'm ready to go in a second. No cables or packs to mess with and I'll never out run the beam.
This is exactly what I was looking for. The light was bright enough for me to see everything at 5 in the morning. Also, strong enough to illuminate signs from a considerable distance. Very easy to charge and mount on bicycle. Also, included helmet mount.
Very bright! This light is easy to mount and doesn't weigh much considering the volume of light that it puts out. Charges on a microUSB adapter which comes with it (AC to USB not included). Also comes with a helmet mount... haven't used, but looks ok.Highly recommend.
bought this in combination with the MagicShine MJ-816E for night trail riding. MagicShine on the handle bars NightRider on my helmet. Love the light weight and bright light! Also easy to take off the helmet and mount in my road bike with both mounts included.
I feel that I need 2 of those when I am riding at night.I have a helmet mounted &#34;light and motion&#34; it's an old fashioned light and I feel that it's more powerful and brighter.But otherwise this light is easy to charge; easy to mount and practical
I did try the bar mount and it was easy to install and it was rock solid. When I decided that this would be my helmet light, the helmet mount was just as easy to install and it too was rock solid. I was a little concerned that it might pop up and down because the angle adjustment is pretty easy but it held true throughout the ride.
I can't speak to the longevity of the battery in this guy as I haven't really pushed it yet, but it's bright enough for trails, mounts up solid, is surprisingly compact, and the helmet mount is a huge bonus. It also works with other NR mounts so if you have a Mako or something you can use it with the helmet mount and leave a mount on your bars for any of them.
Answer: yes
