Light the way.

If you're in the habit of choosing to ride with the stars instead of the sun, you know that making sure you can see where you're going requires a little more planning than it does during the day. Light & Motion's Urban 850 Trail light was designed so that you don't have to stop doing what you love just because the sun goes down — or hasn't come up yet — and at 850 lumens, it claims to be the most powerful single LED bike light available right now.

You never know what types of animals you may be sharing your bike lane or trail with at night, which is why it's helpful that the Urban 850 includes red lighting on each side for added peripheral visibility. Light & Motion uses a light beam pattern meant to maximize riders' depth perception, and they developed a smooth spot beam to help you see clearly on trails. The light can be submerged in up to one meter of water for 30 minutes, which, if you're not planning on riding underwater, means that a rain shower won't hurt the Urban 850.

Take this light to the trails, the road, or through the city on your commute home, just know that on "high" the battery will last continuously for about one and a half hours. You can get up to six hours of battery life if the light is just on low, and it comes with a USB cable for easy on-the-go recharging. In addition to a regular handlebar mount, the Urban 850 also includes a helmet mount and a GoPro mount, and it adds about 121g to your frame.

  • Familiarity: I've used it several times

I have been using Light&Motion products for a while now in some of their other sectors and have always been impressed. This light has not been any exception. This thing is super bright and illuminates a pretty decent distance away.
While I have not drained the battery completely, I have noticed that the indicator light changes to orange about 30-45 minutes into a ride at the brightest setting which concerns me how long it will actually last. Most of the rides I have taken it on have been about an hour long so it hasn't been an issue yet.
FWIW, one evening I passed a few pedestrians who commented that someone had their brights on as I rode passed them. I wasn't on the highest power setting.

Night becomes day

  • Familiarity: I've put it through the wringer

Mountain biking with this in the dark is incredible. Great visibility, light weight, awesome except for a lousy helmet mount that does not hold the light well. The light rotates with the mount and ends up pointing down. I ended up buying a go pro mount and now it is perfect.

Worth every cent!!

  • Familiarity: I've used it once or twice and have initial impressions

This is a super bright light (the image shows the brighest mode on a trail with no light). It works perfect on those trails without light, because its range is wide and long enough to see all road section you need to.

On the other hand, it is pretty easy to mount and unmount and it does not move at all even during downhill; when you put it on the handle bar, it is easy to switch between modes.

Worth every cent!!

Packs a Punch

  • Familiarity: I've used it several times

This little light packs quite a punch for its size. It mounts easily to your bars or the included helmet strap (I have not used it with the helmet strap). The light did not rotate up or down while mountain biking. The light can also be rotated slightly to the right and left as well.

The on/off button is easy to find and use with full finger gloves on. Charging was quick with the included USB cable. The light was plenty bright to ride off road with but having one on the bars and helmet would be even better.

Packs a Punch

this is a great image, thx for sharing

Great Light

  • Familiarity: I've used it several times

I've used this mainly for riding around dusk on the road. It provides more than enough light on the high setting. I generally ride with it in the pulse setting which gives me more visability to automobiles and other road users.

The 850 lumens provides quite a bit of light and I'm excited to try this for night riding on my Mountain Bike. If it's anything like the otherLight and Motion lights that I have it will do great.

Lightweight, affordable and reliable

    For the price, get two and throw one in your pack for back up. I had two of the Urban 800s and loved them but gave them to my Wife and upgraded to the fast charge 850. The light is noticeably whiter and brighter than the 800. They are both lightweight and feature a small green/ red light to let you know when they're done charging. I also got the helmet mount designed specifically for the Smith Forefront helmet.
