    • Good product I feel much more visible with this light flashing behind me.
Style: 350 Lumens, Standard Seatpost Mount
Great product. I utilized this light over a thousand miles last summer without an issue. It’s plenty bright during the day time. Like all the flashing modes. Battery life is good for my needs, on my average rides of 40 to 50 miles.

    • Love this light!
Style: 350 Lumens, Standard Seatpost Mount
This light is amazing and I felt seen. When I'm riding solo, cars rarely ever get up on my rear wheel anymore. I think this light is so bright that they just dont want to be right behind me. I felt seen I the daylight and I felt seen from half a mile away when it's pitch black out. I love the various mixes - important to me as I turn it solid during group rides so not to blind the other riders. And then the various blinking modes for when I'm riding solo. My only gripe about this - and I didn't deduct a star because the light is that good - is the mounting hardware. You have to purchase an external piece of hardware I'd you want to mount it to an aero seatpost. I feel this should come with this light to match current bike trends. I was able to rig something up on my own and it works, bit that was a minor annoyance. Get this light though, it rocks! ... show more

    • My Favorite Taillight
Style: 350 Lumens, Standard Seatpost Mount
I have these on all of my bikes and they are bright enough to be effective, even in daylight. Multiple flash patterns allow you to pick your favorite for the conditions ay hand. Some of mine are over 5 years old and still operating perfectly. While they are relatively expensive, in my opinions they are worth the money. ... show more

    • Cygolite Hypershot 350 & 250 Lumen Bicycle Taillight- 2 is better than one!
Style: 350 Lumens, Standard Seatpost Mount
One thing you need to know, is that this tail light is, in a word, bright! Has a generous number of modes, adjustable brightness and reasonable battery life depending on how you adjust it (the product insert is pretty much right on and the battery performs well over time). Useful certainly at night, but also provides great visibility during the day on those narrow single lane roads where cars go way too fast. With this light, they must see me because they noticeably slow down (I know, don't you wish they'd slow down more often!). Paired with a Cygolite front light in blinking mode, daytime visibility is guaranteed. I've used other brands, but have now transitioned all our bikes to Cygolite. After nearly a year on the road this light is really holding up! ... show more

    • One of the brightest tail lights made!
Style: 250 Lumens, Seatpost Mount
I owned a Cygolite Hotshot 100 for years and a competitors tail light before this. I keep coming back to Cygolite for a reason. Durability and features that are really used (some newer tail lights even adapt to braking which I find to be a gimmick), not features of limited to no use at all. For the reason of price alone, I chose the 250 lumen version of this light. The Hotshot 100 I had was very visible. It just took forever to charge. This light came with just above 50% charge and took less than an hour and a half to charge fully. We'll see if the claims of 3 hour charge time holds factual once i drain the battery to charging level again. Just two gripes about this light and Cygolite should be ashamed of itself. The seatpost clamp does NOT fit a 31.6 mm seatpost. They seem to be holding onto the smaller standard for seatposts. Thankfully, they've now made the standard for tail light mounts and I was able to use the old tail light mount to mount it to the seatpost until I get the T-mount I ordered specifically for my rack in and mounted. The second gripe is common to most bicycle tail lights. However, Cygolite still hasn't addressed their largest complaint. The charging port cover will not last more than a year at best even with the newer cover that I noticed. One of their competitors makes a better port cover, but not much better. Eventually, I'll have to replace it with duct tape to prevent moisture from entering at this point which is what killed the last Cygolite I owned. All said, I still recommend the Cygolite's. Headlamp or tail light. Their products will last even if you dump the bicycle while riding on wet or uneven surfaces. They are well worth their price. I only docked one star for the minimal gripes I had. ... show more

    • Bright is safe
Style: 350 Lumens, Standard Seatpost Mount
This 350 lumen tail light is actually highly effective during the day, if you bike in a lot in traffic this light will get you noticed, the quick release mount allows easy removal when you park your bike and is small enough to pack with you, the adjustable patterns and intensity is great for reducing the intensity for night time rides, I just tip mine down slightly and keep it full power. Caps are easy to remove for charging and construction is good. ... show more
